    Description: This document, which is directed at the fishing sector, researchers, conservationists and fishery administrators, was developed by researchers who are members of the Specialists Group for Marine Turtle Research and conservation in the Southwestern Atlantic Ocean (SWA) in response to the urgent need to evaluate the impact generated on sea turtles by fisheries. Historically, sea turtle conservation efforts have focused almost exclusively on the protection of nesting beaches. Nevertheless, over the last decade, research has proved incidental mortality as a result of fishing activities to be one of the greatest threats to these animals. This type of interaction is not only problematic for turtles, but also generates financial losses for fishermen and businesses. In spite of the efforts that are currently underway, researchers still do not have a detailed understanding of the impact that bycatch produces on sea turtle populations in the SWA. We have a long way to go before its effects can be minimized. Further research is needed regarding the biology and ecology of the various turtle species as well as the effective application of mitigation measures. The life cycles of sea turtles are long and complex. Turtles occupy various ecosystems (nesting beaches, coastal, neritic and oceanic zones, as well as pelagic and demersal areas) throughout their lifetimes, transcending various Exclusive Economic Zones and International Waters. The five species that inhabit the SWA region perform vast feeding and reproductive migrations, traveling through areas where many different fishing fleets operate. Therefore, sea turtles in the SWA interact with virtually all fisheries. These circumstances make it necessary to carry out biological, fishing related and conservation studies on a regional level. The efficiency of the existing international and national legal instruments has yet to be determined, in terms of their effectiveness in protecting sea turtles. In some cases, legislation that is specifically related to the interaction between fisheries and turtles does exist, such as those laws requiring the mandatory use of turtle excluding devices (TEDs). There are also explicit bans on sea turtle capture. Nevertheless, none of these regulations prevent sea turtle bycatch. Although some regional legal instruments are needed, these and the existing legislation will only be effective if they are accompanied by a broader range of permanent education and control measures, to achieve the commitment of all the parties involved. The ecosystem approach is gaining popularity among fishery administration organizations. Research and conservation efforts should also be moving in that direction. A regional and international effort is required in order to compile information regarding the bycatch produced by the various types of fisheries and fleets operating in the area. The enormous increase in fishing pressure that these fleets are exerting in this area has not been accompanied by an increase in information regarding the bycatch of species that have no commercial value. Pelagic longlining is one of the fishing methods, which must be most closely monitored, due to the high levels of bycatch that it produces, as well its ample distribution throughout the region, and the high level of fishing effort that it accounts for. Coastal trawlers and gillnetters must also be considered critical players, because they too produce a large rate of bycatch. These are the three types of fisheries that are most broadly distributed throughout the region, accounting for the majority of the fishing effort. Most of the institutions that work toward sea turtle conservation in the area have only begun to address the issue of bycatch over the last decade. This timeframe is reflected in the scope and quantity of the available publications, as well as the progress of activities directed at mitigating this problem. All of the institutions that have been mentioned in this report have made the gathering of information regarding interaction between sea turtles and fisheries one of their top priorities. Some institutions are even developing working programs for monitoring fisheries and testing mitigation measures. Many of these institutions have managed to develop adequate relationships with fishermen, ship owners and administrators. Nevertheless, limited access to funding is an obstacle to the development and testing of mitigation measures. The SWA network, which is a very valuable instrument that was created in 2003, has allowed the region’s institutions and researchers to exchange information and share their experience, in addition to lending each other support in carrying out joint activities, thus strengthening sea turtle conservation efforts. The capacity demonstrated so far by the region’s researchers and institutions, testifies to their ability to continue to make progress in knowledge generation and tests of bycatch mitigation measures.

    Description: A partir de la firma del Proyecto de Gestión Pesquera DINARA-FAO (UTF/URU/025/URU), en septiembre de 2007, se comenzó a conformar una Unidad de Economía Pesquera. Sus objetivos se focalizaron en fortalecer la capacidad de recolección y análisis estadístico de la información socio-económica del sector. En el 2008 esta Unidad compiló y realizó un análisis de la información comprendida entre los años 2002 y 2007, reanudando luego de varios años esta publicación histórica. La misma fue un éxito en todo sentido, especialmente para consulta de los diferentes actores del sector. La aceptación y receptividad que ha tenido dicha publicación nos motiva y obliga a continuar en esta línea, rumbo a la obtención de un producto de valor y utilidad, basado exclusivamente en información oficial nacional. Este año retomamos la serie anual poniendo nuevamente a disposición de todos información actualizada, completa y de calidad que estamos seguros será nuevamente de gran beneficio para el sector público como privado, así como de interés para el público en general.

    Description: Este documento, dirigido al sector pesquero, investigadores, conservacionistas y administradores de las pesquerías, surge como respuesta de investigadores pertenecientes al Grupo de Especialistas en Investigación y Conservación de Tortugas Marinas en el Atlántico Sud Occidental (ASO) a la urgente necesidad de evaluar el impacto de las pesquerías sobre las tortugas marinas. Históricamente, los esfuerzos referidos a la conservación de las tortugas marinas se han dirigido casi exclusivamente a proteger las playas de anidación. Sin embargo en la última década se ha podido comprobar que una de las mayores amenazas es la mortalidad incidental causada por las pesquerías. Esta interacción no implica únicamente un problema para las tortugas, sino que también genera pérdidas económicas para los pescadores y las empresas.

    Description: El presente trabajo llama la atención a las recientes epidemias de intoxicación histamínicas reportadas en los Estados Unidos, debido al consumo del dorado (Coryphaena hippurus) o Mahi-Mah, contaminado. Esto dió como resultado la prohición de las importaciones de esta especie, proveniente de varios países entre ellos el Ecuador, y siendo el dorado una especie de relativa importancia económica en este país, dicha prohibición ha preocupado al sector pesquero. Los estudios llevados a cabo muestran claramente la susceptibilidad de esta especie a desarrollar histamina. Esto se debe principalmente a la temperatura a la que está expuesta, pues la demora antes de enhielar el pescado es la etapa crítica. Los resultados muestran un aumento exponencial de los niveles de histamina, en ciertos casos después de tan solo 9 horas de almacenaje a temperaturas ambientales entre 25-30°C. Los niveles de histamina en pescado muestreado en el mercado local fueron tan altos como 250 mg/100g de muestra. Se demuestra que el problema se debe fundamentalmente al mal manejo de la captura por parte de la flota artesanal, y la subsecuente falta de infraestructura adecuada para conservarla, es decir, no se enfría el pescado. Sin embargo, el estudio muestra que una reducción de la temperatura del pescado de solo 15° menos, podría dar como resultado un producto de mayor calidad. En el presente trabajo se hacen recomendaciones para establecer un nivel máximo permitido para la exportación de 10 mg%, y se comparan dos métodos rápidos de análisis.

    Description: 153 experimental sets were made with stackable Antillean fish traps in depths of 5 to 30 m in the waters around the Galápagos Island (Ecuador), between Octobre and April 1983. 1,885 fish were caught of 18 species mainly of the families Pomadasyidae, Acanthuridae, Sparidae and Serranidae. The mean catch rate was 5,5 Kg per lift or 0,4 Kg.h-1, and the mean weight of the fish caught was 0,45 Kg. The optimum set duration was found to be between 2 and 18 hours (possibly indicating a high rate of escape). This study took place during the period of the ”El Niño”, when catches of fish in this area generally were low, and it is not known what effect this had. The catches were good compared with other shallow areas, but the fishes caught were mainly of medium quality. It is thought that significant increases in the quantity and quality of the catch could be obtained with commercial traps in deeper areas, but the efficient use of these would require new vessels and equipment, and the resulting increase in fishing effort could lead to overfishing of the most acceptable species of reef fish. Hence the development of fishery using fish traps is not recommended for Galápagos. A study of the biology of the fish caught was carried out. A bibliography of references on fish traps and their use was compiled and is included.

    Description: Le domaine maritime sénégalais s’étend de 18°00 N, -20°00 W, -16°30 E, 12°15 S ; la presqu’île du Cap-Vert située entre 14°30 N et 15°00 N le divise en deux zones aux caractéristiques topographiques distinctes. Au nord, le plateau continental est peu étendu vers le large et orienté Nord-Nord/Est. Au sud de la presqu’île, le plateau s’élargit et le talus continental est orienté nord-sud. L’embouchure du fleuve Sénégal au Sénégal au Nord de la presqu’île du Cap-Vert et celles de la Gambie et de la Casamance au Sud constituent également un trait marquant de cette région. Les travaux réalisés au Sénégal en océanographie ont montré : - l’existence de deux saisons marines aux caractéristiques très différentes qui se succèdent : une saison chaude de juillet à octobre et une saison froide de décembre à mai. Ces deux saisons sont séparées par des périodes de transition. Pendant la saison froide, les alizés (vent de secteur nord-ouest à nord-est) s’établissent et engendrent à la côte une résurgence d’eau profonde (upwelling) vers la surface ; - la mise en évidence de systèmes de grands courants aux caractéristiques différentes : le courant des Canaries et le contre courant équatorial ; - la description de trois grandes houles au large du Sénégal : o la houle de Nord-Nord ouest qui a lieu toute l’année o la houle de Sud-Sud ouest apparaissant pendant l’hivernage o la houle d’ouest possible aux environs du mois de novembre. Le littoral sénégalais représente une zone d’intérêt stratégique à la fois sur le plan démographique, économique et environnemental. Les milieux naturels, dans un état de conservation relativement préservé, produisent des ressources vitales pour les 11 millions d’habitants peuplant le Sénégal. L’économie nationale sénégalaise est très dépendante de ces ressources côtières et marines qui constituent les principales recettes en devises, qu’il s’agisse de pêche ou de tourisme. L’analyse de la situation et des tendances montre que la zone côtière fait l’objet de pressions diversifiées et de plus en plus lourdes. Ces pressions se traduisent souvent par des conflits d’intérêts entre les différents secteurs et par des impacts qui génèrent une dégradation de l’environnement et des conditions de vie des populations. Cette évolution risque ainsi de compromettre les potentialités de développement offertes par les 700 Km de littoral sénégalais. La pression démographique se développe préférentiellement sur la zone côtière qui accueille déjà près de 60% des habitants, notamment dans les centres urbains et les capitale, toutes situées en bord de mer, et qui continuent à recevoir des populations en provenance de l’intérieur, réfugiés climatiques ou économiques, ou simplement jeunesse attirée par les « lumières de la ville ». Cet exode, à l’origine de dysfonctionnements des systèmes de production ruraux qui manquent peu à peu de main d’oeuvre, contribue à son tour à générer des perturbations au niveau des centres urbains où la misère se substitue parfois à la pauvreté.
    Description: Les besoins en matériaux de construction consécutifs à cette évolution démographique entraînent des prélèvements massifs de sable sur les plages qui ont à leur tour des conséquences négatives sur l’érosion et la protection du littoral. La fragilisation des cordons dunaires augmente ainsi les risques d’inondations des terres, la ville de Saint Louis étant particulièrement vulnérable à cet égard. Les besoins en développement ont conduit à la réalisation d’infrastructures le long du littoral. Ces constructions, qui tiennent trop rarement compte des contraintes environnementales, ont entraîné des répercussions structurelles sur l’équilibre de la zone côtière. Ainsi, les barrages anti-sel, tel le barrage de Diama sur le fleuve Sénégal, ont entraîné des répercussions sur le fonctionnement de certains écosystèmes côtiers. En condamnant les influences des apports d’eau douce ils appauvrissent les milieux situés en aval, stérilisant peu à peu des zones riches en ressources ainsi que les économies et les cultures qui en dépendent. Le ralentissement des courants et la baisse de salinité en amont du barrage favorisent l’apparition de certaines plantes envahissantes, telles que la bilharziose ou le paludisme. Les effectifs de poissons dépendant de milieux à salinité variable sont directement affectés, expliquant par exemple une chute de près de 70% des captures dans le bas delta du Sénégal. Les besoins du développement se traduisent également par l’amélioration ou la création d’axes routiers qui, dans la majorité des cas, longent la zone côtière. Ces ouvrages entraînent des impacts directs sur l’environnement, tels la destruction des mangroves là où les routes barrent l’écoulement des marées (exemple de la route Samba Dia – Djifère. Les systèmes de production traditionnels sont en règle générale peu préparés à faire face à des circuits de commercialisation organisés à une échelle régionale ou internationale, où à des technologies plus performantes, et éprouvent des difficultés à maintenir un contrôle sur leur terroir. Faute de pouvoir opérer une métamorphose rapide de leur système de production, le risque existe de voir peu à peu disparaître des savoir-faire d’une grande valeur dans la gestion même de ces territoires et de leurs ressources et , plus généralement, des cultures qui leur sont associées. Le développement industriel exerce des impacts potentiels ou réels de grande magnitude sur la zone côtière et marine. Les secteurs les plus significatifs à cet égard sont le tourisme et les hydrocarbures. Concernant le premier, les infrastructures, principalement orientées vers le tourisme balnéaire, sont en grande majorité installées à proximité directe de la zone côtière. L’absence quasi généralisée d’études d’impacts approfondies et indépendantes a conduit à de nombreux échecs. Ainsi, la plupart des projets ont été pensés et réalisés sans tenir suffisamment compte des contextes socio-économiques, culturels et environnementaux dans lesquels ils s’insèrent. Certaines réalisations ont été planifiées sur des secteurs soumis à une forte érosion littorale, compromettant de façon irrémédiable non seulement les investissements mais l’utilisation ultérieure du site, comme cela s’est produit sur les plages au sud immédiat du Cap Skirring. Les questions relatives à la disponibilité en eau douce qui se posent de façon cruciale dans le Saloum par exemple, à la gestion des déchets et des eaux usées ne sont que rarement prises en considération de façon structurelle et durable, conduisant à la dégradation de l’environnement ou à des conflits avec les communautés locales qui nuisent à la qualité même du tourisme. L’exploration et l’exploitation des ressources en hydrocarbures représentent aussi un secteur d’intérêt stratégique avec une généralisation des prospections. Si la découverte de gisement d’intérêt commercial représente une opportunité majeure pour l’économie nationale, elle soulève néanmoins un certain nombre de questions au regard de l’environnement. En effet les des puits. Parmi ces risques nous pouvons citer les impacts des études sismiques sur les organismes marins, notamment poissons et cétacés, le rejet de fluides toxiques et déblais de forage, le déversement des eaux de production et les pollutions aiguës dues à des accidents intervenant pendant le forage, le stockage ou le transport. Le Sénégal en ce moment, en est au stade de la prospection. Toutefois, pour ce qui concerne le transport d’hydrocarbures, plus de 90 000 0000 de tonnes d’hydrocarbures transitent par les côtes sénégalaises. Les modèles de dérive des nappes élaborés par la Compagnie pétrolière Woodside en relation avec le champ de Chinguetti, actuellement en cours de production au large de la Mauritanie, montrent des probabilités d’impact sur les côtes allant du golfe d’Arguin jusqu’à Dakar, en cas d’accident. La surexploitation des ressources halieutiques constitue également un problème au niveau de l’environnement marin et côtier. En effet, si une partie de la fluctuation des biomasses peut s’expliquer par les changements du régime des upwellings, la baisse des captures s’explique par un effort de pêche excessif, que ce soit dans le sous-secteur industriel ou artisanal. A cette surcapacité vient s’ajouter la présence de flottes illicites non déclarées et non réglementées. L’utilisation de certains engins ou pratiques de pêche contribue à aggraver la situation : la pêche crevettière est à l’origine de prises accidentelles qui représentent jusqu’à 85 % du total des captures, incluant des espèces protégées comme les tortues marines, et qui sont rejetés à la mer . Les chaluts de fonds, qui vont pêcher jusqu’à 800 m de profondeur, ainsi que les dragues à coquillages entraînant des dégâts structurels sur les écosystèmes De plus l’influence des marchés à l’exportation exerce des pressions sélectives sur certaines espèces, les espèces démersales de poissons, céphalopodes étant les plus recherchées sur le marché. Les changements climatiques ont également des impacts négatifs sur l’environnement marin et côtier. On sait que l’élévation du niveau marin aura des répercussions directes sur les installations humaines littorales ainsi que sur les écosystèmes insulaires et côtiers. Des zones de mangroves entières qui ne disposent pas des conditions écologiques pour s’adapter peuvent disparaître, entraînant des risques accrus d’érosion et d’inondation. Ces mêmes risques se multiplient avec la fréquence accrue des épisodes météorologiques exceptionnels tels que les ondes de tempêtes capables de drosser les pirogues à la côte ou de provoquer la rupture de cordons dunaires. On sait par ailleurs que le réchauffement de la température des mers influe négativement sur la productivité des océans et la dynamique des courants tels que le courant profond originaire de l’antarctique et qui exporte vers le Sénégal et les autres pays de la sousrégion des sels nutritifs présents dans les upwellings. On observe également une diminution de la puissance des alizés qui pourrait avoir des répercussions directes sur la force des upwellings et donc sur la productivité des pêcheries et du milieu marin en général. La stratégie de réponse proposée combine une protection des zones côtières importantes et un reboisement des dunes littorales dans les secteurs de la côte nord et de la Flèche de Sangomar particulièrement menacés. L’évaluation économique de cette stratégie montre qu’elle est coûteuse mais nettement en deçà de la valeur économique des terres qu’elle sera amenée à protéger. Des efforts complémentaires devront cependant être faits pour évaluer le coût d’autres solutions de protection telles que le nourissement artificiel des plages. Par ailleurs, la stratégie envisagée ne répondant qu’à l’un des impacts des changements climatiques, à savoir les inondations, toute une série de mesures dites d’accompagnement ont été suggérées qui visent à diminuer la vulnérabilité en gérant mieux les ressources présentes dans la zone côtière, en développant les techniques de récupération des sols salés et en prenant des mesures législatives et institutionnelles appropriées. Enfin, il est très important de souligner que ces différentes mesures ne devraient être envisagées que dans un cadre plus global de gestion intégrée des zones côtières, seul à même d’assurer la participation de l’ensemble des acteurs concernés, l’éducation, la recherche et l’information environnementales mais aussi la cohérences et le suivi des mesures.

    Description: This paper examines the arrival of a new group of fishermen on the Kenyan coast and what this has meant for the state of fishery resources. It reviews four subject areas: access and the number of fishermen; the fishermen’s identity; the choice of fishing gear; and the fishing grounds selected. Data were collected from a small number of fishing households in the villages of Uyombo and Takaungu in Kilifi District, using mainly qualitative research methods. Local households on the Kenyan coast face increasing pressure on land as well as on marine resources. The declining economic situation and greater pressure on land have made people turn to fishing as an income-generating activity. This group of fishermen is referred to as the ‘new’ generation of fishermen as they have been involved in fishing for only one or two generations (including the current one) in contrast to the ‘old’ generation from families who have been fishing or in fishingrelated activities for much longer. The old generation of fishermen and their households have also diversified their incomes, with many fishing households turning to farming, for example, with women and grown-up children involved in various activities. The new generation of fishermen, mainly of the Mijikenda population group, has often been blamed for the loss of traditional access regulations and for using harmful fishing gear. This paper discusses the new generation of fishermen and their identity as they perceive it and relates this to employment generation as a policy measure for marine conservation.

    Description: This report describes a preliminary analysis of borehole seismic data to determine VLF/Sub-bottom Seismic Noise in the Atlantic and the preliminary results of finite difference modelling for a Cape Fear environment. Noise levels were not a simple function of depth and there are indications that noise levels may depend on local geology about a given receiver position and/or on clamping. Coherency of the noise was generally poor (〈0.8) and was independent of depth. There is no evidence for distinct polarizations or directionality of the noise. The lowest determined value for ambient noise power on the vertical component was 10-4 nm2/Hz in the frequency range from 5-50 Hz. The better clamped horizontal component had comparable power values. In conclusion, although the drill ship was on the site and drill pipe was in the hole, analysis of the data for a large number of windows can provide meaningful upper bounds on the ambient noise levels in the upper crust.

    Description: Durante las últimas décadas se ha observado un incremento de la captura (descartada y retenida) de condrictios en las pesquerías artesanales e industriales, conjuntamente con un rápido crecimiento de las pesquerías no reguladas, lo cual ha ocasionado una disminución en muchas poblaciones de este grupo de peces en todos los mares del mundo. La sobrepesca y los elevados niveles de mortalidad ocasionados por la captura incidental, asi como la degradación y contaminación de áreas costeras donde se ubican las zonas de alimentación, reproducción y cría para muchas especies de condrictios, han colocado a este grupo de peces en una situación difícil. Estos hechos, combinados con el bajo potencial reproductivo y la estrategia de vida de la mayoría de las especies de condríctios, no permiten una recuperación de las poblaciones, cuando las mismas se ven enfrentadas a períodos de sobreexplotación. En las aguas de Uruguay ocurren aproximadamente 100 especies de condrictios, muchas de las cuales son capturadas por diferentes pesquerias, tanto de forma incidental como dirigida. Debido a la preocupación a nivel internacional sobre la sustentabilidad de las pesquerías de tiburones, la FAO en 1998 realizó una consulta internacional a expertos y desarrolló un “Plan de Acción Internacional para la Conservación y el Manejo de los Tiburones” (PAI - Tiburones), el cual fue adoptado en 1999. El objetivo del PAI - Tiburones es asegurar la conservación, el manejo y el uso sustentable a largo plazo de los tiburones. Al hacer referencia a “tiburones”, se incluyen a todos los condrictios (tiburones, batoideos y quimeras). Este documento se divide en dos Capítulos y cuatro Anexos. El primer capítulo incluye los objetivos del PAN - Condrictios Uruguay y las medidas propuestas para alcanzar los mismos. El segundo capítulo contiene un diagnóstico general de los condrictios, las pesquerías y el marco jurídico. Como anexos se incluyen una lista de especies de condrictios citadas para Uruguay junto a su status en las listas rojas de la UICN, una reseña biológica de las especies consideradas prioritaras, una lista de abreviaturas, y listas de instituciones y personas que participaron de las reuniones desarrolladas durante el proceso de elaboración del PAN – Condrictios Uruguay. Las medidas propuestas por el PAN - Condrictios Uruguay se deberán aplicar a todas las pesquerías efectuadas por buques de bandera uruguaya, incluso los que operan fuera de la zona económica exclusiva de Uruguay.

    Description: La captura incidental en pesquerías comerciales ha sido identificada como una de las principales amenazas para la conservación de este grupo de aves, siendo los albatros (familia: Diomedeidae) y los petreles (familia: Procellariidae) las especies más afectadas. Debido a que los albatros y petreles presentan una gran longevidad y una baja fecundidad, pocas crías y un lento desarrollo, sus poblaciones son muy sensibles al aumento en la tasa de mortalidad causado por la captura incidental en las pesquerías. Anualmente son capturadas y muertas miles de aves marinas en las pesquerías comerciales que operan con diferentes configuraciones de palangre alrededor del mundo. Este arte, entre otras causas, está contribuyendo al descenso de varias poblaciones de albatros y preteles, configurando un claro riesgo de extinción de estas especies, si se permite que las tendencias actuales persistan. Las pesquerías de arrastre también interactúan con las aves marinas provocando la mortalidad de las mismas en un importante número. Otras pesquerías que capturan aves marinas son las que operan con redes de enmalle, redes de cerco y poteras. Respondiendo a la necesidad de reducir la mortalidad de aves marinas la Organización de las Naciones Unidas para la Agricultura y la Alimentación (FAO) desarrolló un Plan de Acción Internacional para Reducir la Captura Incidental de Aves Marinas en las Pesquerías de Palangre, el cual propicia la elaboración de Planes de Acción Nacionales en cada uno de sus países miembros. El objetivo del Plan de Acción Nacional – Aves Marinas de Uruguay es presentar un marco general que permita instrumentar medidas para la reducción de la captura incidental de aves marinas en todas las pesquerías de Uruguay.

    Description: A highly efficient frequency-controlled sound source based on a tunable high-Q underwater acoustic resonator is described. The required spectrum width was achieved by transmitting a linear frequency-modulated signal and simultaneously tuning the resonance frequency, keeping the sound source in resonance at the instantaneous frequency of the signal transmitted. Such sound sources have applications in ocean-acoustic tomography and deep-penetration seismic tomography. Mathematical analysis and numerical simulation show the Helmholtz resonator's ability for instant resonant frequency switching and quick adjustment of its resonant frequency to the instantaneous frequency signal. The concept of a quick frequency adjustment filter is considered. The discussion includes the simplest lumped resonant source as well as the complicated distributed system of a tunable organ pipe. A numerical model of the tunable organ pipe is shown to have a form similar to a transmission line segment. This provides a general form for the principal results, which can be applied to tunable resonators of a different physical nature. The numerical simulation shows that the “state-switched” concept also works in the high-Q tunable organ pipe, and the speed of frequency sweeping in a high-Q tunable organ pipe is analyzed. The simulation results were applied to a projector design for ocean-acoustic tomography.

    Description: In this study, we develop a framework for measuring the value of harmful algal bloom (HAB) predictions. The framework captures the effects of both private and public responses to HABs. Using data from the New England nearshore commercial shellfish fishery and impact estimates for a large-scale HAB event in 2005, we illustrate how the potential value of HAB forecasts may be estimated. The results of our study suggest that the long-term value of a HAB prediction and tracking system for the Gulf of Maine is sensitive to the frequency of HAB events, the accuracy of predictions, the choice of HAB impact measures, and the effectiveness of public and private responses.

    Description: This paper introduces a perturbative inversion algorithm for determining sea floor acoustic properties, which uses modal amplitudes as input data. Perturbative inverse methods have been used in the past to estimate bottom acoustic properties in sediments, but up to this point these methods have used only the modal eigenvalues as input data. As with previous perturbative inversion methods, the one developed in this paper solves the nonlinear inverse problem using a series of approximate, linear steps. Examples of the method applied to synthetic and experimental data are provided to demonstrate the method's feasibility. Finally, it is shown that modal eigenvalue and amplitude perturbation can be combined into a single inversion algorithm that uses all of the potentially available modal data.

    Description: The management and conservation of the world's oceans require synthesis of spatial data on the distribution and intensity of human activities and the overlap of their impacts on marine ecosystems. We developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems. Our analysis indicates that no area is unaffected by human influence and that a large fraction (41%) is strongly affected by multiple drivers. However, large areas of relatively little human impact remain, particularly near the poles. The analytical process and resulting maps provide flexible tools for regional and global efforts to allocate conservation resources; to implement ecosystem-based management; and to inform marine spatial planning, education, and basic research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halpern, Benjamin S -- Walbridge, Shaun -- Selkoe, Kimberly A -- Kappel, Carrie V -- Micheli, Fiorenza -- D'Agrosa, Caterina -- Bruno, John F -- Casey, Kenneth S -- Ebert, Colin -- Fox, Helen E -- Fujita, Rod -- Heinemann, Dennis -- Lenihan, Hunter S -- Madin, Elizabeth M P -- Perry, Matthew T -- Selig, Elizabeth R -- Spalding, Mark -- Steneck, Robert -- Watson, Reg -- New York, N.Y. -- Science. 2008 Feb 15;319(5865):948-52. doi: 10.1126/science.1149345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, 735 State Street, Santa Barbara, CA 93101, USA. halpern@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18276889" target="_blank"〉PubMed〈/a〉

    Description: Atlantic bluefin tuna populations are in steep decline, and an improved understanding of connectivity between individuals from eastern (Mediterranean Sea) and western (Gulf of Mexico) spawning areas is needed to manage remaining fisheries. Chemical signatures in the otoliths of yearlings from regional nurseries were distinct and served as natural tags to assess natal homing and mixing. Adults showed high rates of natal homing to both eastern and western spawning areas. Trans-Atlantic movement (east to west) was significant and size-dependent, with individuals of Mediterranean origin mixing with the western population in the U.S. Atlantic. The largest (oldest) bluefin tuna collected near the northern extent of their range in North American waters were almost exclusively of western origin, indicating that this region represents critical habitat for the western population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rooker, Jay R -- Secor, David H -- De Metrio, Gregorio -- Schloesser, Ryan -- Block, Barbara A -- Neilson, John D -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):742-4. doi: 10.1126/science.1161473.

    Description: The West side of lake of Garda, in Northern Italy, was struck by a ML=5.2 earthquake on November 24, 2004. The felt area is rather large (from Venice to Milan) and the damaged area consists of 66 municipalities, with a number of homeless of about 2200 and estimated direct damages of 215 millions of euros. Most of the damaged structures are old masonry buildings and churches, while there were almost no damage to reinforced concrete structures. The observed distribution of macroseismic intensity shows a strong azimuthal dependence, with high intensity level in a 10x10 km2 area located SW to the epicentre and rather large dispersion of values (ranging from V to VII-VIII) in the first 10 km epicentral distance. Taking into account the vulnerability level of the damaged structures and the features of the geological formations, we tried to explain the observed damage distribution in terms of finite fault properties of the source, despite the moderate magnitude of the event. Thus we hypothesised a fault geometry from seismotectonic considerations and we simulated the event by a high frequency simulation technique (Deterministic Stochastic Method, DSM). The synthetic ground motion parameters were converted into intensity values by empirical relationships and local geological conditions were considered to explain some discrepancies between simulated and observed intensities. It was possible to adequately reproduce both the observed distribution of macroseismic intensity and the ground motion recorded by an accelerometric station located at about 13 km epicentral distance.

    Description: The exploitation status of cardinalfish (Epigonus crassicaudus) yielded in Chile between 33° to 41°S was analyzed. An indirect assessment was performed between 1997 and 2003 through size-structured model with a transition matrix defining the changes among sizes. The model was calibrated using size structures, official landings, catch-per-unit of effort (CPUE) taken from commercial fishing logbooks and standardized by generalized linear models (GLM). After 7 years of an intense fishery activity, we concluded that the cardinalfish resource in Chile is on the recruitment overfishing limit. On 2003, the spawning biomass with respect to the virginal spawning biomass is close to 40%. The biological references points (BRP) based on spawning per recruit biomass (SPR) support this assesment because the fishing mortality level on 2003 (Fact) was very close to fishing mortality level of 40% of SRP at virginal value (F40%).

    Description: Oceanic spreading centers are sites of magmatic, tectonic, and hydrothermal processes. In this thesis I present experimental and seismological constraints on the evolution of these complex regions of focused crustal accretion and extension. Experimental results from drained, triaxial deformation experiments on partially molten olivine reveal that melt extraction rates are linearly dependent on effective mean stress when the effective mean stress is low and non-linearly dependent on effective mean stress when it is high. Microearthquakes recorded above an inferred magma reservoir along the TAG segment of the Mid-Atlantic Ridge delineate for the first time the arcuate, subsurface structure of a long-lived, active detachment fault. This fault penetrates the entire oceanic crust and forms the high-permeability pathway necessary to sustain long-lived, high-temperature hydrothermal venting in this region. Long-lived detachment faulting exhumes lower crustal and mantle rocks. Residual stresses generated by thermal expansion anisotropy and mismatch in the uplifting, cooling rock trigger grain boundary microfractures if stress intensities at the tips of naturally occurring flaws exceed a critical stress intensity factor. Experimental results coupled with geomechanical models indicate that pervasive grain boundary cracking occurs in mantle peridotite when it is uplifted to within 4 km of the seafloor. Whereas faults provide the high-permeability pathways necessary to sustain high-temperature fluid circulation, grain boundary cracks form the interconnected network required for pervasive alteration of the oceanic lithosphere. This thesis provides fundamental constraints on the rheology, evolution, and alteration of the lithosphere at oceanic spreading centers.

    Description: The first year of the New England Regional Fisheries Management Council has been marked by its experimental aura. Neither the Council nor the various sectors (representatives of the Federal and State agencies, members of the fishing industry, the public at large) were clear as to exactly what they were to do and how they were to do it--except in the broadest, most flexible (ambiguous?) terms. This created certain operational difficulties, and confusion for those whose livelihood was affected by the Council's operation. This latter group, particularly the fishermen, knew little of what went on, save in terms of the 'public facet of the Council--i.e., that portion of the Council's performance which occurred during the monthly meetings which were open to the public and which, supposedly, received public input at that time. This study defines that public face, deliberately avoiding the presentation of any data which was not accessible to the average audience participant, in an attempt to present some of the behavior which all participants demonstrated and which generated responses and reactions on the part of the other sectors. It uses standard anthropological techniques of data gathering and analysis to show the degree to which impression management on the part of all the actors operated in a systematic fashion to produce action, reaction, and counter-action. Particularly emphasized is the communication aspects.

    Description: A new tomographic technique is employed to investigate the structure and dynamics of the Pacific upper mantle. We invert band-center travel times of ScS reverberations and frequency-dependent travel times of direct S phases, upper-mantle guided waves such as SS and SSS, and the R1 and G1 surface waves for the 2D composite structure in the plane of two Pacific corridors. The frequency-dependent travel times of the turning and surface waves are measured from all three components of ground motion as phase delays relative to a radially-anisotropic, spherically-symmetric oceanic mantle model, and their 2D Fréchet kernels are constructed by a coupled-mode algorithm. The travel times of the primary ScSn and sScSn phases and their first-order reverberations from the 410 and 660 discontinuities are measured as individual phases and the 2D Fréchet kernels for these band-limited signals are calculated using the paraxial ray approximation. The model parameters include shear-speed variations throughout the mantle, perturbations to radial shear-wave anisotropy in the uppermost mantle, and the topography of the 410 and 660 discontinuities. We construct vertical tomograms through two mantle corridors: one between the Tonga subduction zone and Oahu, Hawaii, which traverses the central Pacific Ocean; and the other between the Ryukyu subduction zone and Oahu, which samples the northern Philippine Sea, the western Pacific, and the entire Hawaiian swell. Tests demonstrate that the data sets for the two corridors resolve the lateral structure in the upper mantle with a scale length of a few hundreds kilometers and greater but that the resolving power decreases rapidly in the lower mantle. The model for the Tonga-Hawaii corridor reveals several interesting features, the most significant being a regular pattern of high and low shear velocities in the upper mantle between Tonga and Hawaii. These variations, which are well resolved by the data set, have a horizontal wavelength of 1500 km, a vertical dimension of 700 km, and an amplitude of about 3%, and they show a strong positive correlation with seafloor topography and geoid-height variations along this corridor. The geoid highs correspond to a series of northwest-trending swells associated with the major hotspots of the Society, Marquesas, and Hawaiian Islands. Where these swells cross the corridor, they are underlain by high shear velocities throughout the uppermost mantle, so it is unlikely that their topography is supported by thermal buoyancy. This result is substantiated by the model from the Ryukyu-Hawaii corridor, which exhibits a prominent, fast region that extends beneath the entire Hawaiian swell. This anomaly, which resides in the uppermost 200-300 km of the mantle, is also positively correlated with the undulations of the Hawaiian-swell height. The other dominant features in the Ryukyu-Hawaii model include the high-velocity subducting slabs beneath the Ryukyu and Izu-Bonin seismic zones, which extend throughout the entire upper mantle; a very low-velocity in the uppermost 160 km of the mantle beneath the northern Philippine Sea, which is ascribed to the presence of extra water in this region; and a pronounced minimum in the amount of radial anisotropy near Hawaii, which is also seen along the Tonga-Hawaii corridor. A joint inversion of the data from the two corridors reveals the same anomaly pattern and clearly demonstrates that the swells in the Central Pacific are underlain by fast velocities. It is therefore implied that the topography of the swells in the central Pacific is supported by a chemical buoyancy mechanism which is generated by basaltic volcanism and the formation of its low-density peridotitic residuum. While the basaltic depletion mechanism can produce high shear velocities in the uppermost 200 km, it cannot explain the depth extent of the fast anomalies beneath the swells which, along Tonga-Hawaii corridor, extend well into the transition zone. It is therefore hypothesized that the central Pacific is underlain by a system of convective rolls that are confined above the 660-km discontinuity. It is likely that these rolls are predominantly oriented in the direction of plate motion (like "Richter rolls ") but the limited depth of the fast anomaly beneath the Hawaiian swell (200-300 km) suggests that their pattern is probably more complicated. Nevertheless, this convection pattern appears to be strongly correlated with the locations of the Tahitian, Marquesan, and Hawaiian hotspots, which raises interesting questions for Morgan's hypothesis that these hotspots are the surface manifestations of deep-mantle plumes.

    Description: Fish and fishermen appear to be in a serious decline in New England. The haddock are overfished, inshore herring stocks are depleted, yellowtail flounder and lobster are scarce. The popular image is of grizzled fishermen, their boats chipped, scarred, old-fashioned hulks of wood tied up two and three abreast along the rotting wharves and piers of New England's depressed port towns. In this research project, we wanted to determine the state of the New England fishing industry and to propose acceptable methods for the management of the fishery. During our early discussions with the fishing industry people, we mentioned that we were interested in limited effort programs as they might be applied to New England fishermen. We carefully, and probably tediously, explained the "theory of limited effort" and we were generally thought to be daft. We were told we had things backwards--that the fishing industry needed more fish, more men, more boats - and that the way to accomplish this was to get a 200-mile fishing limit and kick the foreigners out. One of these wishes has come true - in the spring of 1976, P.L. 94-265 established a 200-mile fishing zone off the United States, with regional management councils to make management plans and allocate the resources first to United States fishermen, with surpluses to foreign fishermen.

    Description: Laterally extensive, well-developed clinoforms have been mapped in Early Cretaceous deposits located in the northeastern 27,000 km2 of the Colvile Basin, North Slope of Alaska. Using public domain 2-D seismic data, well logs, core photographs, and grain size data, depositional geometries within the Nanushuk and Torok formations were interpreted in order to constrain the transport conditions associated with progradation of the shoreline and construction of the continental margin out of detritus shed from the ancestral Brooks Range. Using STRATA, a synthetic stratigraphic modeling package, constructional clinoform geometries similar to those preserved in the North Slope clinoform volume (32,400 km3) were simulated. Sediment flux, marine and nonmarine diffusivities, and basin subsidence were systematically varied until a match was found for the foreset and topset slopes, as well as progradation rates over a 6 milion year period. The ability of STRATA to match the seismically interpreted geometries allows us to constrain measures of possible water and sediment discharges consistent with the observed development of the Early Cretaceous c1inoform suite. Simulations indicate that, in order to reproduce observed geometries and trends using constant input parameters, the subsidence rate must be very small, only a fraction of the most likely rate calculated from the seismic data. Constant sediment transport parameters can successfully describe the evolution of the prograding margin only in the absence of tectonic subsidence. However, further work is needed to constrain the absolute magnitude of these values and determine a unique solution for the NPR-A clinoforms.

    Description: Like all species, humans have exercised their impulse to perpetuate and propagate themselves. In doing so, we have domesticated landscapes and ecosystems in ways that enhance our food supplies, reduce exposure to predators and natural dangers, and promote commerce. On average, the net benefits to humankind of domesticated nature have been positive. We have, of course, made mistakes, causing unforeseen changes in ecosystem attributes, while leaving few, if any, truly wild places on Earth. Going into the future, scientists can help humanity to domesticate nature more wisely by quantifying the tradeoffs among ecosystem services, such as how increasing the provision of one service may decrease ecosystem resilience and the provision of other services.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kareiva, Peter -- Watts, Sean -- McDonald, Robert -- Boucher, Tim -- New York, N.Y. -- Science. 2007 Jun 29;316(5833):1866-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Nature Conservancy, 4245 North Fairfax Drive, Suite 100, Arlington, VA 22203, USA. pkareiva@tnc.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17600209" target="_blank"〉PubMed〈/a〉

    Description: Impacts of chronic overfishing are evident in population depletions worldwide, yet indirect ecosystem effects induced by predator removal from oceanic food webs remain unpredictable. As abundances of all 11 great sharks that consume other elasmobranchs (rays, skates, and small sharks) fell over the past 35 years, 12 of 14 of these prey species increased in coastal northwest Atlantic ecosystems. Effects of this community restructuring have cascaded downward from the cownose ray, whose enhanced predation on its bay scallop prey was sufficient to terminate a century-long scallop fishery. Analogous top-down effects may be a predictable consequence of eliminating entire functional groups of predators.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Myers, Ransom A -- Baum, Julia K -- Shepherd, Travis D -- Powers, Sean P -- Peterson, Charles H -- New York, N.Y. -- Science. 2007 Mar 30;315(5820):1846-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biology, Dalhousie University, 1355 Oxford Street, Halifax, NS B3H 4J1, Canada.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17395829" target="_blank"〉PubMed〈/a〉

    Description: Captive breeding is used to supplement populations of many species that are declining in the wild. The suitability of and long-term species survival from such programs remain largely untested, however. We measured lifetime reproductive success of the first two generations of steelhead trout that were reared in captivity and bred in the wild after they were released. By reconstructing a three-generation pedigree with microsatellite markers, we show that genetic effects of domestication reduce subsequent reproductive capabilities by approximately 40% per captive-reared generation when fish are moved to natural environments. These results suggest that even a few generations of domestication may have negative effects on natural reproduction in the wild and that the repeated use of captive-reared parents to supplement wild populations should be carefully reconsidered.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Araki, Hitoshi -- Cooper, Becky -- Blouin, Michael S -- New York, N.Y. -- Science. 2007 Oct 5;318(5847):100-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, 3029 Cordley Hall, Oregon State University Corvallis, OR 97331, USA. arakih@science.oregonstate.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17916734" target="_blank"〉PubMed〈/a〉

    Description / Table of Contents: Substantially revising and updating the classic reference in the field, this handbook offers a valuable overview and myriad details on current chemical processes, products, and practices. No other source offers as much data on the chemistry, engineering, economics, and infrastructure of the industry. The Handbook serves a spectrum of individuals, from those who are directly involved in the chemical industry to others in related industries and activities. It provides not only the underlying science and technology for important industry sectors, but also broad coverage of critical supporting topics. Industrial processes and products can be much enhanced through observing the tenets and applying the methodologies found in chapters on Green Engineering and Chemistry (specifically, biomass conversion), Practical Catalysis, and Environmental Measurements; as well as expanded treatment of Safety, chemistry plant security, and Emergency Preparedness. Understanding these factors allows them to be part of the total process and helps achieve optimum results in, for example, process development, review, and modification. Important topics in the energy field, namely nuclear, coal, natural gas, and petroleum, are covered in individual chapters. Other new chapters include energy conversion, energy storage, emerging nanoscience and technology. Updated sections include more material on biomass conversion, as well as three chapters covering biotechnology topics, namely, Industrial Biotechnology, Industrial Enzymes, and Industrial Production of Therapeutic Proteins.

    Description: Two earthquakes (both having Mw 5.7) struck the eastern portion of Molise on October 31 and November 1, 2002. Both caused severe damage over a 2000 km2 region straddling Molise and Puglia. The two larger shocks and the rather unusual aftershock sequence surprised most Italian seismologists and tectonicists. Although Italy has a good record of historical and instrumental seismicity and its main seismogenic trends are quite established, the epicentral location, depth and kinematics of this earthquake sequence were largely unexpected. In fact, the 2002 Molise earthquakes shed light on a previously unsuspected style of seismogenic faulting in this region. From the seismotectonic perspective, much of the significance of the two quakes arises from the possibility that this style of faulting might be shared by several much larger quakes that took place on the Adriatic side of the southern Apennines. In the first part of this paper we briefly describe the main seismological characteristics of the sequence. These were largely derived from the analysis of data supplied by permanent networks and from a preliminary analysis of data recorded by a portable network deployed a few hours after the first shock. In the second part of the paper we discuss the seismotectonic characteristics of the sequence in the framework of Italian tectonics and the implications for future earthquakes in the same region.

    Description: A correlation has been recently found between large earthquakes and the succeeding largest 9 explosive eruptions of the last century, which has been interpreted as a product of co- and post-seismic stress diffusion. Here, we check the statistical significance of the proposed coupling by using a larger dataset, and investigate the reliability of the causality hypothesis. We find that the volcanoes with VEI ≥ 4 eruptions underwent, in the few decades before the volcanic event, higher seismic stress perturbations due to large earthquakes compared to other volcanic areas. The correlation is statistically significant and it is not explained by a spatio-temporal clustering of eruptions and earthquakes due to tectonic pulses. This implies that the large earthquakes indeed triggered the eruptions.

    Description: We investigate conceptually, analytically, and numerically the biases in the estimation of the b-value of the Gutenberg-Richter law and of its uncertainty made through the least squares technique. The biases are introduced by the cumulation operation for the cumulative form of the Gutenberg-Richter law, by the logarithmic transformation, and by the measurement errors on the magnitude. We find that the least squares technique, applied to the cumulative and binned form of the Gutenberg-Richter law, produces strong bias in the b-value and its uncertainty, whose amplitudes depend on the size of the sample. Furthermore, the logarithmic transformation produces two different endemic bends in the Log(N) versus M curve. This means that this plot might produce fake significant departures from the Gutenberg-Richter law. The effect of the measurement errors is negligible compared to those of cumulation operation and logarithmic transformation. The results obtained show that the least squares technique should never be used to determine the slope of the Gutenberg-Richter law and its uncertainty.

    Description: Seychelles is composed of over 100 islands with a land area of approximately 455 km², centred close to 4°30'S and 55°30'E. The combined coastline is approximately 600 km long, the oceanic shelf totals about 50 000 km² and the Exclusive Economic Zone (EEZ) is over 1 370 000 km². The total population (1994 census) stands at just under 74 000. in 1994, the population registered a growth rate of 2.2%. The GDP (1994) was SR 2373.8 million, fisheries representing 4.8% of this sum. Licensing agreements for foreign fishing activities provided a yearly revenue of SR8 million. Port Victoria is seen as a prime centre for tuna fishing operations in the Indian Ocean. In the artisanal fishery just under 900 persons are working. The largest contributor to catch by vessel type are the traditional whaler vessels representing 47.8% of the total catch. Over 66.3% of the catch is by the handline method. Carangidae representing 24% and Lutjanidae 19% of total landings. There are six specific objectives to the fisheries sector policy, which aims as resource development and maximisation of potential benefits. Nearshore fishery resources are considered to be heavily exploited, however opportunities exist around the distant islands and in deeper waters off the Mahe plateau shelf. Aquaculture of molluscs and prawns is being developed and carried out. The main constraints to development are seen as the lack of skilled manpower and foreign exchange.

    Description: The trophic relations of two apex predators, yellowfin and bigeye tuna (Thunnus albacares and T. obesus), and their prey were investigated in the western tropical Indian Ocean. The contents of 173 non-empty stomachs were analysed from specimens caught with longlines and purse seine during scientific and fishing cruises. Diet data were processed by occurrence, by number, and by wet weight and a comparison of diets between surface and deep swimmers made. Crustaceans were the almost exclusive food source of surface-swimming bigeye tuna, with the stomatopod (Natosquilla investigatoris) being the sole prey item recorded in this category. The diet of deep-swimming yellowfin tuna was balanced between epipelagic fish, crustaceans and cephalopods. Bigeye tuna fed predominantly on cephalopods and mesopelagic fish (Scopelarchidae and Paralepididae), for which this predator appeared to be the most active chaser. The diet of the two predators reflects their ability to catch the prey, and their vertical distribution.

    Description: Lake Manzalah; the largest delta Lake in Egypt represents a dynamic system that has been undergoing continuous and pronounced changes since long times. In the last year’s this Lake faced drastic problems that retarded its environmental and fisheries development; the most serious one is the discharge of waste water. It is attempted in the present study to investigate the chemical characters of Lake Manzalah water during 2001-2002. Water temperature ranged from an average of 12.35oC in January and 29.14oC in July. Dissolved Oxygen, pH and total dissolved solids were found in ranges optimum for the living of marine and freshwater fish species. The average concentrations of nutrients lied in the following ranges: 1.24 to 4.89 μmol PO4 -3 l-1 , 5.08 to 28.73 μmol SiO4 -2 l-1 and 1.81 to 17.7 μ_mol NO3-1 l-1 The concentrations of phosphorus and nitrogen compounds were found to be relatively higher at the southern regions of the Lake near to the outlets of the drains.

    Description: This paper models the effect of changes in wetlands yields within the freshwater fishery of (the Kenyan segment) of Lake Victoria. Specifically, it models the nutrient retention function of wetlands as a buffer against fertilizer run-off from agriculture, and the impact of nutrient loading on the fishery. Run-off from the watershed is among the major causes of eutrophication in the lake, along with atmospheric deposition and sewage and other organic discharges from domestic and industrial activities. The ecological component of the model captures the interactions between phosphorus loading, wetland area, water quality and fish stocks. Chlorophyll-a concentration is used as a proxy for phytoplankton density, and as a measure of nutrient enrichment. The impact of this on fish stocks is then estimated using using Ecopath. The economic component of the model then evaluates the effect of changes in stocks on performance in the fishery, given the regulatory regime in Kenya. We use the results to obtain an estimate of the value of the nutrient retention function of wetlands on the margins of the lake.

    Description: Over the past decade, exports of fish and fishery products from developing countries have increased rapidly. However, one of the major challenges facing developing countries in seeking to maintain and expand their share of global markets is stricter food safety requirements in industrial countries. Kenyan exports of Nile perch to the European Union provide a notable example of efforts to comply with such requirements, overlaid with the necessity to overcome restrictions on trade relating to immediate food safety concerns. Although food safety requirements were evolving in their major markets, most notably the EU, most Kenyan exporters had made little attempt to upgrade their hygiene standards. Likewise, the legislative framework of food safety controls and facilities at landing sites remained largely unchanged. Both exporters and the Kenyan government were forced to take action when a series of restrictions were applied to exports by the EU over the period 1997 to 2000. Processors responded by upgrading their hygiene controls, although a number of facilities closed, reflecting significant costs of compliance within the context of excess capacity in the sector. Remaining facilities upgraded their hygiene controls and made efforts to diversify their export base away from the EU. Legislation and control mechanisms were also enhanced. Hygiene facilities at landing beaches were improved, but remain the major area of weakness. The Kenyan case illustrates the significant impact that stricter food safety requirements can have on export-oriented supply chains. It also demonstrates how such requirements can exacerbate existing pressures for restructuring and reform, while prevailing supply and capacity issues constrain the manner in which the supply chain is able to respond. In Kenya most of the concerted effort to comply with these requirements was stimulated by the sudden loss of market access in very much a “crisis management” mode of operation, illustrating the importance of responding to emerging food safety requirements in a proactive and effective manner. This paper - a product of the International Trade Department, Poverty Reduction and Economic Management Network - is part of a larger effort in the network to understand the challenges and opportunities facing developing countries associated with evolving international standards for food and other products.

    Description: The increasing power of computers and numerical methods (like spectral element methods) allows continuously improving modelization of the propagation of seismic waves in heterogeneous media and the development of new applications in particular time reversal in the three-dimensional Earth. The concept of time-reversal (hereafter referred to as TR) was previously successfully applied for acoustic waves in many fields like medical imaging, underwater acoustics and non destructive testing. We present here the first application at the global scale of TR with associated reverse movies of seismic waves propagation by sending back long period time-reversed seismograms. We show that seismic wave energy is refocused at the right location and the right time of the earthquake. When TR is applied to the Sumatra-Andaman earthquake (26 Dec. 2004), the migration of the rupture from the south towards the north is retrieved. Therefore, TR is potentially interesting for constraining the spatio-temporal history of complex earthquakes.
