    Description: The genus Ctenochaetus is reportad in the waters of the Colombian Pacific based on two specimens of C. marginatus (Valenciennes) collected in 1993 at Gorgona Island (2°59' N, 78° 12' W). These specimens differ inseveral morphometric characteristics from thosepreviously examined. Such differences appear to be an artifact of the small number of specimens formerly examined and the consequent narrow ranges reportad. We suggest that temperature variability affects the distribution of C. marginatus in the tropical eastern Pacific.
    Description: El género es Ctenochaetus reportad en las aguas del Pacífico colombiano a partir de dos especímenes de C. marginatus (Valenciennes) recogidos en 1993 en la Isla Gorgona (2 ° 59 'N, 78 ° 12' W). Estos ejemplares difieren inseveral características morfométricas de thosepreviously examinados. Estas diferencias parecen ser un artefacto del pequeño número de muestras examinadas anteriormente y reportad los rangos estrechos consecuente. Sugerimos que la variabilidad de la temperatura afecta la distribución de marginatus C en el Pacífico tropical oriental.

    Description: Over the last decade eutrophication of freshwater artificial reservoirs in Cuba occurred in parallel to oligotrophication of estuarine and coastal waters. These two processes influenced both freshwater and marine fisheries. A dramatic shift in species composition in freshwater fisheries has occurred, from dominance by cichlids (tilapia) to dominance by cyprinids. The high fishery yield from some reservoirs, and shift in species composition, seems related to progressive eutrophication of reservoirs by nutrient subsidies from different anthropogenic activities; particular those related to the size of urban areas within their watersheds. On the other hand, marine landings of estuarine-dependent species declined more significantly than for other groups associated with seagrass beds–coral reefs and oceanic waters. The ratio between catches of estuarine-dependent species and those associated with seagrass beds and coral reefs, decreased significantly over the last 20 years. The decrease in landings was more evident in typical estuarine species, such as shrimps (Litopenaeus schmitti and Farfantopenaeus notialis), mangrove oyster (Crassostrea rhizophorae) and mullets (Mugil spp.). River damming increased during the same period and is significantly correlated with these decreases. It is hypothesized that two different processes acted synergistically, leading to dramatic decreases of several orders of magnitude, in the catches of estuarine species over the last decade: the trapping of nutrients and sediments by river damming, and a drastic reduction in nutrient inputs from land-based sources due to reduced fertilizer use. These are postulated to have affected not only estuarine resources, but also the whole coastal ecosystem.
    Description: Durante la última década, la eutrofización de los embalses artificiales de agua dulce en Cuba se produjo en paralelo a oligotrophication de estuarios y costeras aguas. Estos dos procesos de influencia de agua dulce y la pesca marina. Un cambio dramático en la composición de las especies en la pesca de agua dulce se ha producido, de la dominación de los cíclidos (tilapia) a la dominación de ciprínidos. La alta producción de la pesca de algunos embalses, y el cambio en las especies composición, parece relacionada con la progresiva eutrofización de los embalses de las subvenciones de nutrientes de diferentes actividades antropogénicas, especialmente las relacionado con el tamaño de las zonas urbanas dentro de sus cuencas. Por otro lado, los desembarques de especies marinas de estuario-dependientes disminuyeron significativamente más que para otros grupos asociados con algas marinas Los arrecifes de coral-camas y las aguas oceánicas. La relación entre las capturas de las especies que dependen de los estuarios y las asociadas a las praderas marinas y Los arrecifes de coral, se redujo significativamente en los últimos 20 años. La disminución en los desembarques fue más evidente en especies típicas de estuarios, tales como camarones (Litopenaeus schmitti y Farfantopenaeus notialis), ostra de mangle (Crassostrea rhizophorae) y la lisa (Mugil spp.). El represamiento del Río aumentó durante el mismo período y se correlaciona significativamente con estas disminuciones. Se planteó la hipótesis de que dos procesos diferentes actúan de forma sinérgica, que conduce a una disminución drástica de varios órdenes de magnitud, en las capturas de las especies de estuario en la última década: la captura de nutrientes y sedimentos por represas río, y una reducción drástica de los aportes de nutrientes de fuentes terrestres, debido a la reducción del uso de fertilizantes. Se postula que han afectado no sólo a los recursos estuarinos, sino también todo el ecosistema costero.

    Description: Production of mangrove oyster (Crassostrea rhizophorae Guilding, 1828), north of Villa Clara, Cuba Province, tends to decline since 1980, accentuating from 2003 on. Despite regulations to protect the resource, minimum legal size and catch closures, the year 2008 presents the landing smaller volumes of the past 50 years. An analysis of the variability of catches in relation to natural and human factors, allows for precipitating causes of low productivity of this fishery resource; between the most representatives are expanding storage capacity of river water, salinity increment, the increase in frequency and intensity of hurricanes and the mismanagement of the extraction of oyster.
    Description: La producción de ostión de mangle (Crassostrea rhizophorae, Guilding, 1828), al norte de la provincia de Villa Clara, Cuba, tiende a la disminución desde de 1980, acentuándose a partir del año 2003. A pesar de regulaciones para la protección del recurso, talla mínima legal y vedas de captura, el año 2008 presenta los menores volúmenes de desembarque de los últimos 50 años. Un análisis de la variabilidad de las capturas, en relación con factores naturales y antrópicos, permite establecer causas desencadenantes de la baja productividad de este recurso pesquero; las más representativas son, la ampliación en la capacidad de embalse de aguas fluviales, aumentos de la salinidad, el incremento en la frecuencia e intensidad de los huracanes y un manejo inadecuado de la actividad extractiva de ostión.

    Description: Las capturas de langosta espinosa Panulirus argus (Latreille, 1804) en Cuba alcanzaron sus mayores volúmenes en la década de 1980 con un promedio anual de 11565 ton. En la década de 1990, la captura descendió a un promedio de 9327 ton, lo cual se ha visto agudizado entre 2000 y 2007 con un promedio de 6262 ton y una mayor variabilidad de las capturas, a pesar de un perfeccionamiento del sistema de manejo pesquero dado por: la disminución del esfuerzo pesquero y de la tasa de mortalidad por pesca desde 1999, el aumento del período de veda desde 2001 y el incremento gradual de la talla mínima legal de captura a partir de 2004. Los análisis más recientes sobre el estado de esta pesquería fueron presentados en el Quinto Taller Regional sobre la Evaluación y la Ordenación de la Langosta Común del Caribe en septiembre 2006 (Puga et al, 2006; FAO, 2007), donde se reconoció por la comunidad científica especializada que la pesquería de langosta cubana se encontraba bien manejada y plenamente explotada (no sobre- explotada) y se concluyó que además de la mortalidad por pesca, otros factores ajenos al sector pesquero estaban produciendo afectaciones en la abundancia del recurso, al causar daños al hábitat 1 en zonas de cría, influyendo negativamente por esta vía sobre el reclutamiento y la producción de langostas. Entre estos aspectos para Cuba se señalaron: la mayor frecuencia e intensidad de huracanes durante el último decenio, el desarrollo de las zonas costeras, la construcción de presas en las cuencas de captación de los ríos y de carreteras en el Archipiélago Sabana-Camagüey comunicando la isla principal con los cayos y los cayos entre si (pedraplenes).

    Description: Se efectúa un estudio de la fauna acompañante del Mero, Epinephelus morio, en la pesquería con palangre de fondo del Banco de Campeche, México, durante el periodo 1987-2009. En la investigación se consideró información de 32 cruceros de investigación realizados en la etapa como parte del convenio pesquero firmado por Cuba y México para la evaluación sistemática del recurso. Se determinó la composición por especie y talla de las capturas, sus variaciones en la abundancia relativa, estructura de tallas, así como el índice de diversidad de Brillouin, la riqueza de especies (Margalef, 1980), la dominancia numérica y la constancia, estas ultimas valoradas según el esquema propuesto por Bodenheimer (1955). Se encontró que la fauna acompáñate de E. morio esta representada por 69 especies, agrupadas en 3 clases y 12 órdenes. De ellos, el orden mejor representado lo constituyó Perciformes con las familias Serranidae, Lutjanidae, Scombridae, Carangidae y Haemulidae como las más abundantes en número. Dentro de estas, dominaron las especies L. campechanus y O. chrysurus, apreciándose que las entidades mejor representadas son, L. campechanus (100%), O. chrysurus (96,87%) y M. bonaci (73,2%). Los largos medios observados se encontraron por encima de las tallas de primera maduración reportadas en la literatura. Sólo E. nigritus y L. analis presentaron individuos inmaduros. Se reportan tallas máximas superiores a las reportadas en la bibliografía en M. interstitiaslis (150cm), M. bonací (155cm) y E. nigritus (125cm). Se determinó que el rendimiento (cpue) y la diversidad de la fauna acompañante poseen una relación inversa con la disminución de la biomasa de mero. Por su parte, la diversidad y riqueza de especie presentaron sus mayores valores concordando con las temporadas de lluvias.

    Description: La Commission Sous Régionale des Pêches (CSRP), qui est un organisme intergouvernemental de coopération halieutique dont l’objectif global est l’harmonisation à long terme, des politiques des pays membres en matière de préservation, de conservation et d'exploitation durable de leurs ressources halieutiques et le renforcement de leur coopération au profit du bien-être de leurs populations respectives, a obtenu par l’intermédiaire de la Banque mondiale, un Don du Fonds pour l’Environnement Mondial (FEM) et du Gouvernement du Japon, pour la préparation d’un Projet Régional des Pêches en Afrique de l’Ouest (PRAO) pour trouver une solution à la problématique susvisée. Ce projet implique 9 pays côtiers: la Mauritanie, le Cap Vert, le Sénégal, la Gambie, la Guinée Bissau, la Guinée, le Sierra Léone (Etats membres de la CSRP), ainsi que le Libéria et le Ghana. Le PRAO comprend trois composantes : (1) Bonne Gouvernance et Gestion Durable des Pêches ; (2) Réduction de la Pêche Illicite ; (3) Augmentation de la Contribution des Ressources Halieutiques dans les Economies Locales (incluant la réalisation d’infrastructures et équipements dans les pêcheries). Certes, les activités prévues dans le cadre du PRAO sont pressenties pour contribuer au développement du secteur de la pêche dans les pays ciblés et apporter des bénéfices aux populations locales. Toutefois, elles pourraient engendrer dans certains cas des effets négatifs aux niveaux environnemental et social (notamment celles prévues dans la composante 3), si des mesures adéquates ne sont pas prises au préalable. Afin de minimiser ces effets défavorables, il a été requis l’élaboration de la présente Evaluation Environnementale et Sociale (EES).

    Description: Ce travail représente une contribution à l'étude de l'activité de pêche hauturière dans le gouvernorat de Médenine, particulièrement, au niveau du port de Zarzis ; durant la période (juin 2005-juin 2006). Il consiste à réaliser, grâce à des enquêtes menées au port, deux types d'analyses : une analyse quantitative afin de déterminer les débarquements saisonniers moyens des espèces les plus débarquées par la pêche hauturière et une analyse qualitative pour établir les structures démographiques des espèces les plus exploitées dans la région. Les résultats obtenus ont montré que, durant la période d'étude, les principales espèces débarquées par la pêche hauturière sont la sardinelle, le maquereau, le saurel, le rouget blanc, le pageot, la thonine, la seiche et la crevette royale. En examinant les débarquements saisonniers moyens des espèces les plus débarquées par type de pêche, nous avons remarqué que deux ou trois espèces dominent pour chaque saison. De plus, l'analyse des structures démographique des apports a montré que la majorité des individus débarqués sont matures, à l’exception du maquereau dont les captures sont constituées d’individus immatures, surtout pendant les saisons d’été et d’automne.
    Description: This work represents a contribution to the study of the offshore fishing activity in the governorate of Medenine, particularly at the port of Zarzis, during the period (june 2005-june 2006. It is to realize, through surveys conducted at the port, two types of analyzes: a quantitative analysis to determine the average seasonal landings of most landed species by fishing offshore units and qualitative analysis to determine the demographic structure of the most exploited species in the region. The obtained results showed that during the period of study, the main landed species by offshore fishing are sardinella, mackerel, horse mackerel, white mullet, sea bream, skipjack tuna, cuttlefish and the caramote prawn. By examining the average seasonal landings of the most landed species, we noticed that, for each season, two or three species dominate. Furthermore, analysis of demographic structures of the landings showed that the majority of landed individuals are mature, with the exception of mackerel catches which are composed of immature individuals, especially during the seasons of summer and autumn.

    Description: El presente artículo da una descripción detallada de la elaboración y del "curado" de cuerdas de curricán, utilizadas anteriormente para la pesca en Taganga, un pueblo pescador en la costa norte de Colombia. Antes del "curado", estas cuerdas de fibras de algodón y de fabricación industrial, eran o destorcidas o torcidas a mano nuevamente, o tensionadas y envueltas con una cuerda más delgada del mismo material. El "curado" que siguió a estas operaciones se efectuó tanto en una cocción de corteza de las raíces zanconas de mangle, y/o por medio de un frote de estas cuerdas con los hypocotylos del mismo árbol (Rhizophora manglr). Por medio de las técnicas aquí descritas, los pescadores aspiraban a aumentar la resistencia de sus aparejos de pesca en el agua de mar.
    Description: The present paper gives a detailed description of the elaboration and curing of curricán Unes, formerly used as fishing lines in Taganga, a small fishing village on the northem coast of Colombia. These lines, made of cotton fibers and produced industrially, were disassembled and then retwisted by hand, or tightened and then carefully covered with a thinner string of the same material. The curing {"curado") that followed these operations was achieved by immersion of the lines into a boiled infusión of the bark of the prop roots of mangroves (Rhizophora mangle) and/or a rinsing with the hypocotyls of the same trees. By means of the techniques mentioned, the fishermen sought to improve the resistance of their fishing gear to sea water.

    Description: During a 3 week study, a total of 55 individuals of the redlip blenny (Ophioblennius atlanticus) were observed for at least two 15-minute periods, and several for ten of such periods. The sizes of their territories were estimated, the color pattern of each specimen an intra and interspecific interactions were recorded. The mean territory size of the redlip blenny in the study area appeared to be greater than that of these blennies studied in Curacao and Barbados by NURSALL (1977), the difference reflecting perhaps different methods of identifying the territories or a lower density of O. atlanticus in the Santa Marta área. Territories did not appear to be as consistently defended at the study area as at Barbados/Curacao and our impression ¡s that individuals holding large territories are less likely to defend their borders. It seems possible that light colored individuals are protected by their coloration from attack by dark colored territory owners. In territorial defense the redlip blennies grabbed each other tighthy by the mouth and struggled in this position repeatedly for about 15 seconds. Interspecific antagonism was common in the present study, the redlip blennics defended their territory frequently against Eupomacentrus dorsopunicans or E. partitus.
    Description: Durante un estudio de tres semanas, un total de 5 i individuos del bií'nido Ojih'toblcnnius atlnniicur. fueron observados por lo menos durante dos períodos de 1 í minutos para cada individuo y en algunos casos hasta por 10 de estos periodos. Se estimó el área de sus respectivos territorios y se tomó notí de los patrones de coloración de cada espécimen y de las relaciones intra e interespecificas de ellos. El tamaño promedio del territorio de estos blénidos resultó ser mayor que el de los respectivos territorios estudiados por NURSALL (1977) en Curacao y Barbados. Esta diferencia posiblemente se debe a un método diferente de definir los territorios o refleja una densidad menor de la población de O. aílanticus en Santa Marta, Los territorios del área fueron defendidos con menor intensidad a como lo fueron los de Barbados/ Curacao y es nuestra impresión que individuos ocupando un territorio extenso tienden a defender sus límites en menor grado. El color claro de algunos individuos probablemente los protege de agresiones por parte de individuos de color oscuro. En el acto de defensa territorial intraespecífica, los blénidos se agarran por sus bocas y se sacuden mutuamente durante aproximadamente 15 segundos , pudiéndose repetir esti varias veces. Con frecuencia se observarondefensas de los territorios dirigidas hacia los peces doncella Eupomacentrus dorsopunicnas y E. partitus.

    Description: Se ha estudiado la variación anual de la condición de la lisa Mugil incilis Hancock en la Ciénaga Grande de Santa Marta (CGSM), la mayor laguna costera del Caribe Colombiano, haciendo énfasis en la influencia ejercida por factores ambientales como la salinidad, la temperatura y la transparencia de las aguas sobre la condición de esta especie de Mugilidae. Las diferencias estacionales observadas en la condición de M. incilis están evidentemente relacionadas con su desarrollo gonadal y dependen de la disponibilidad de alimento. La dieta de M. incilis se basa en detritos y su suministro de alimento parece ser muy afectado por el aporte fluvial a la CGSM, el cual es también responsable de los cambios en la salinidad de la laguna, esto explica la relación inversa (r = -0.82) hallada entre la salinidad y la condición de M. incilis expresada por C = 0.9949 - 0.0057 S(°/oo). La variación anual de la salinidad sigue un patrón rítmico de cambios estacionales, no precisamente "in situ", sino en regiones continentales distantes: las cabeceras de los tributarios de la CGSM. Estas lisas desovan en aguas del Caribe adyacente a la CGSM y su período de migración (dic-marzo) comienza con su mejor condición física, y retornan a sus áreas de alimentación en la CGSM 2 a 4 semanas después, hasta el final de la migración, con su condición mínima ya que al parecer estas lisas no se alimentan durante su migración de desove. No se observaron cambios relacionados con las variaciones de la temperatura. Las aguas más turbias coincidieron con los sitios de alimentación de M. incilis.
    Description: The annual variation in condition of the mullet Mugil incilis Hancock has been studied in the Ciénaga Grande de Santa Marta (CGSM). The largest coastal lagoon on the Colombian Caribbean, with emphasis on the influence of such environmental factors as salinity, temperature and transparence of the waters on the condition of this species of Mugilidae. Seasonal differences observed in condition of M. incilis are evidently related to gonadal development and depend on food availability. The diet of M, incilis is based on detritus and its food supply seems to be very influenced by river discharge which also accounts for the salinity changes in the lagoon. this explains the in verse correlation (r = -0.82) found between salinity and condition of the mullets expressed as C = 0.9949 - 0.0057 S (°/oo). Annual salinity variation follows a rhythmic pattern of seasonal changes. not precisely "in situ", but in distant continental regions: the headwaters of the tributarles of the CGSM. These mullets spawn in Caribbean waters adjacent to the CGSM and their migración period (Dec-March) begins with their best physical condición, returning to their feeding áreas in the CGSM 2 or 4 weeks lacer, until the end of the migración, with their lowest condition since these mullets apparently do not feed at all during the spawning migration. No change related to temperature variations was observed. and turbid waters were the rule in M. incilis feeding sites.

    Description: Un análisis de los datos arqueológicos e históricos sobre la pesca en Cuba muestra que el impacto de la población aborigen sobre los recursos pesqueros no fue significativo debido a su baja densidad poblacional y a las tecnologías de pesca. El interés por el oro, el tamaño de la población, las limitaciones tecnológicas para la pesca y preservación de las capturas así como las preferencias dietéticas de los españoles todas indican que la pesca tampoco fue una actividad económica importante durante los tres siglos que siguieron a la llegada de Colón. Las preferencias por la carne de res y el bacalao salado y la baja tasa de crecimiento poblacional durante el período colonial determinaron que la mayor parte de los recursos pesqueros, con la excepción del manatí y las tortugas marinas, permanecieran prácticamente inexplorados durante varios siglos después de la Conquista. Los datos estadísticos e históricos revelan que la pesca experimentó un rápido crecimiento desde 1950 y este patrón parece ser una característica común en el Caribe así como en otras partes del mundo. Las presiones sobre la vida marina fueron más evidentes en la segunda mitad del siglo xx cuando el crecimiento poblacional, las mejoras tecnológicas y las demandas del mercado aceleraron el sector pesquero así como la urbanización en la mayoría de los países del caribe.

La talla de los organismos para ambos sexos presenta un comportamiento estratificado por profundidades, los ejemplares de mayor tamaño se encuentran a profundidades superiores y viceversa, lo cual se ajusta a una recta de regresión (r2 = 0.88; a = 0.05). Las hembras alcanzaron largos promedio del manto superior a los machos, incrementándose la presencia de machos en las capturas desde enero a abril. Se estimaron los largos promedio de primera maduración, como 20.5 y 26.5 cm de largo del manto para machos y hembras respectivamente. Se observó un aumento de la proporción de individuos maduros de febrero a abril, haciéndose más marcado este fenómeno en los machos, que en su mayoría presentaban abundantes espermatóforos en el saco. Se obtuvo la relación largo-peso para hembras y machos y para la combinación de ambos sexos.
    Description: In 1987 a program for the biological sampling of squid ///ex argentinas, was begun on board of a fishing ship belonging to the Cuban Fisheries-Fleet, wich operates in the Patagonian Shelf. The lengths of both sexes presented a estratified pattern with individuals of larger size found in higher depths and viceversa; this pattern is adjusted to a regression line (r2 = 0.88; a = 0.05). Pernales reached average length larger (han males and the rate of males in catches increased from january to april. The first maturation average length was estimated about 20.5 cm for males and 26.5 cm for females. An increase of the rate of mature individuals was observed between february and april emphazasing ¡n males which showed abundant espermatophores in the sac.

    Description: A yield per recruit model has been used to compare the effects of mesh size increment on the yields and revenues of the fisheries of Cameroon under two different cases. Case 1 assumes the commercial fishery to move from the exploitation of three age-groups to two age-groups with no interactions with the artisanal fishery, whereas Case 2 takes into account these interactions. The difference in the percentage increase of yield per recruit between case 1 and case 2 is 61% at current fishing (46% and 18% yield per recruit increment in cases 1 and 2 respectively). The usually accepted long-term yield per recruit increment with increase of age at first capture (with a single non-interacting fisheries) is, in this case, cancelled out. However, the revenues increase by 72% and 63% in cases 1 and 2 respectively. Therefore the economic approach, compared with purely biological analyses, is more convincing. In general, as fisheries always interact, a single-fishery management approach should not be the rule as it is at present; management strategies should consider interactions between different fisheries and be based on their economic performances and not, as said earlier, on purely biological considerations. This is because a biological approach to fisheries management will, at best, be modified by economic factors, or, at worst, be ignored totally in favour of economic policies.

    Description: La pêche au Sénégal joue un rôle économique et social très important par une contribution globale de près de 11% du PIB primaire et 2,3% du PIB total. Elle occupe de façon directe et indirecte environ 600 000 personnes, soit près de 17% de la population active selon la DP M. Cependant ces dernières décennies, les études ont montré que le secteur traverse une crise aiguë se traduisant par une raréfaction croissante des ressources, notamment les espèces nobles qui ont une forte valeur commerciale. Cette crise est due entre autres à une surexploitation de ces ressources qui est le résultat d’un manque de maîtrise de l’effort de pêche surtout pour les pêcheries artisanales (80% des débarquements et plus de 60% des approvisionnements des industries de la place) au regard du volume de ressources disponibles. Ce manque de maîtrise est dû essentiellement par un défaut du suivi contrôle et surveillance au niveau de la pêche artisanale par l’Etat, qui n’a pas les moyens humains et matériels pour appliquer des mesures de gestion, qui pour la plupart ne sont pas adaptées aux réalités des acteurs à la base. L’objet de cette étude est d’analyser une nouvelle approche axée sur la surveillance participative basée sur l’émergence d’initiatives locales de cogestion au niveau des quatre (04) sites du programme GIRMaC que sont ; Ouakam, Ngaparou, Foundiougne et Bétenty. Il ressort de cette étude que : • Le secteur de la pêche traverse une crise aiguë due principalement selon les acteurs à un défaut de suivi, contrôle et surveillance tel que appliqué actuellement ; • L’approche de cogestion avec des bases juridiques cohérentes, comme le propose le programme GIRMaC peut être un moyen viable pour solutionner à la crise que traverse la pêche ; • D’une part le système Suivi Contrôle et Surveillance coûte cher, d’autre part que ces coûts sont fortement amoindris lorsque les acteurs participent à l’effort de surveillance, par une démarche de surveillance participative en cogestion.

    Description: The first meeting of the South West Indian Ocean EAF Regional Task Group (RTG) was held in Mombasa, Kenya, from 27 to 30 January 2009, together with an ecological risk assessment methodology workshop. It was attended by 20 partic ipants from the South West Indian Ocean (SWIO) countries, the South West Indian Ocean Fisheries Project (SWIOFP), the Agulhas and Somali Currents Large Marine Ecosystems (ASCLME) project, the Scientific Committee of the South West Indian Ocean Fisheries Commission, the United Nations Environment Programme (UNEP)/Nairobi Convention Implementation Unit, the African Union Commission and FAO. The RTG is an implementation structure under the EAF-Nansen project GCP/INT/003/NOR and serves as the forum for training in ecological risk assessment that is the methodology used for the identification and prioritization of issues requiring management attention. The main objectives of the meeting and workshop we re to discuss and facilitate key processes and activities for the implementation of the ecosystem approach to fisheries management in the South West Indian Ocean region including the modalities for the formation and functioning of the RTG and National Task Groups (NTGs). It was explained that, to be able to achieve the objectives of implementing an ecosystem approach to fisheries at the national level, certain key structures have to be in place including the NTG with representatives of key stakeholders in a given fishery and that would take the lead in the process. An overview of the key concepts and process of the ecological risk assessment methodology were clarified. Participants were also introduced to the preparation of EAF baseline reports to be used as initial input for the work on ecosystems approach to fisheries. It was explained that the preparation of the report is to be led by national and regional experts and overseen by the NTG. For the exercises the participants worked in three subgroups formed during the meeting with each group selecting a chairman who moderate d the discussions and a rapporteur. The participants expressed satisfaction with the development of a communication strategy for the project and especially with the participatory approach used.

    Description: Français - Les traits essentiels de la côte sénégalaise, repères historiques de la pêche, communautés de pêcheurs, caractéristiques des flottes et modes d’accès à la ressource et d’interaction sont analysés. Les caractéristiques, tendances décroissantes de l’abondance,niveaux d’exploitation, mesures d’aménagement, relations interspécifiques, changements potentiels et sources de variation des stocks démersaux côtiers sont précisés. Les notions de tactiques et stratégies de pêche sont passées en revue, conceptualisées puis étudiées.Le modèle «Dynamique Conjointe Exploitation Ressource» utilisé repose sur la définition de 4 typologies. L’utilisation de méthodes de classification et de connaissances d’experts conduit à considérer 32 stocks, 31 strates, 82 tactiques et 25 flottilles artisanales et chalutières. Les typologies sont articulées avec la prise en compte de paramètres relatifs à l’économie, aux stocks, flottilles et règles de décisions. L’ajustement est satisfaisant en partie. Toutefois, le modèle garde son importance en matière de prospective et d’objectifs à atteindre via la définition de variables de contrôle. Notre travail peut être considéré comme une esquisse invitant à un groupe de travail élargi aux experts des institutions halieutiques nationales voire, sous-régionales. Des propositions sont faites sur les bases de données, les licences de pêche et l’étude des tactiques et stratégies à mener suivant des pas de temps raisonnables pour tenir compte du grand dynamisme des pêcheries. Dès lors qu'il s’agit de caractériser l'impact de la pêche sur l'écosystème, ces travaux sont des éléments essentiels des recherches à faire sur la dynamique des écosystèmes exploités. English - The essential features of the Senegalese coast, fisheries history, fishermen's communities, artisanal and trawling fleet’s characteristics and their way of accessing to the resource and interactions are described. The characteristics, evolutionary tendencies of abundance, level of exploitation, measures of fisheries management, interspecific relationship, potential evolutionary changes and sources of variation of coastal demersal stocks are specified. Tactics and strategies are reviewed, conceptualized and studied. We used the model "Dynamique Conjointe Exploitation Ressource" which lies on 32 stocks, 31 strata, 82 tactics, 25 fleets and several other parameters dealing with stocks, fleets, economy and making decision rules. The adjustment is partially satisfactory but the model is of great interest for prospective studies and objectives to reach once defined variables of control. Our work is an outline calling for an enlarged working group implying national or sub regional fisheries institutional experts. Tactics and strategies studies, re-actualized in artisanal fisheries, are performed for the first time in industrial fisheries. The typological approach is simple, pertinent, efficacy and fast. Propositions are made relatively to databases, fishing licenses and tactics and strategies studies that should be implemented according to a reasonable time steps in order to take into account the big dynamism of the Senegalese fisheries. As it is intended to characterize fisheries impact on ecosystem, these works are one of essential research elements on the dynamic of exploited ecosystems.

    Description: En Afrique de l'Ouest, la zone littorale et ses ressources représentent une composante essentielle pour le développement. Près de 60% de la population est concentrée à moins de 20 km des côtes . La part des ressources halieutiques dans l'alimentation des populations est très importante et croissante. Au Sénégal par exemple, elles contribuent jusqu'à 70% des apports en protéines. A cela s'ajoute le poids socio-économique très important de la pêche en général et de la pêche artisanale en particulier devenue l'un des secteurs les plus stratégiques pour l'économie nationale en Mauritanie notamment. Le Cadre Stratégique de Lutte contre la Pauvreté du Gouvernement Mauritanien considère que : "compte tenu des possibilités qu'elle offre en terme de création d'emplois et de sécurité alimentaire notamment pour les populations pauvres, mais également de génération de recettes en devises, la pêche artisanale revêt une grande priorité, un plan décennal de développement lui sera consacré ".

    Description: This study presents a framework for analyzing the interactions between aquaculture and capture fisheries in the context of ecosystem-based management. We extend a model of the economic and ecological systems in coastal New England by incorporating an aquaculture sector in a computable general equilibrium (CGE) model and by examining the forage fish and aquaculture link in a marine food web. We show that aquaculture and commercial fisheries interact in a complex way throughout the economic and ecological systems.

    Description: The biological benefits of marine reserves have garnered favor in the conservation community, but “no-take” reserve implementation is complicated by the economic interests of fishery stakeholders. There are now a number of studies examining the conditions under which marine reserves can provide both economic and ecological benefits. A potentially important reality of fishing that these studies overlook is that fishing can damage the habitat of the target stock. Here, we construct an equilibrium bioeconomic model that incorporates this habitat damage and show that the designation of marine reserves, coupled with the implementation of a tax on fishing effort, becomes both biologically and economically favorable as habitat sensitivity increases. We also study the effects of varied degrees of spatial control on fisheries management. Together, our results provide further evidence for the potential monetary and biological value of spatial management, and the possibility of a mutually beneficial resolution to the fisherman–conservationist marine reserve designation dilemma.

    Description: Description du secteur de la pêche Avec la Mauritanie, le Sénégal est de loin le plus grand producteur de produits de pêche de la sous région. Avec 718 km de cote et un territoire maritime de 198km2, 15 745 km2 de superficie fluviale, 2 estuaires, des mangroves et un lac de 350km2, le Sénégal possède tous les atouts des plus grands producteurs de pêche. Le potentiel annuel de captures s’élève à 500 000 tonnes. Le secteur a subi une croissance spectaculaire ces trente dernières années : les débarquements sont passés 50 000 tonnes en 1965 à plus de 450 000 en 1997. Le secteur se compose principalement de deux sous-secteurs : la pêche industrielle et la pêche traditionnelle ou artisanale. Cette dernière, vielle de plusieurs siècles a su s’adapter et se moderniser au cours des dernières décennies. La flotte de pêche artisanale est dynamique et diversifiée ; selon les estimations, en 2005 il y avait plus de 13 000 pirogues. La pêche artisanale se concentre dans sept régions maritimes et fluviales du pays: Dakar, Thiès, Saint Louis, Fatick, Zinguinchor, Louga et Kaolack. Le port de Kayar dans la région de Thiès correspond à la principale zone de débarquement de la pêche artisanale avec environ 70% des débarquements. Dans le secteur industriel, les pêcheurs travaillent à bord d’une flottille de petits sardiniers, de 143 chalutiers destinés à la pêche d’espèces demersales, de 3 sardiniers et de 42 thoniers. Alors que le Sénégal domine largement le sous-secteur demersale avec 70% des chalutiers opérants, le pays ne possède que 6 thoniers contre 38 étrangers, dont une partie seulement des captures est débarquée au Sénégal. La pêche industrielle est concentrée autour de la capitale dans le Port autonome de Dakar et des ports secondaires de Saint Louis, Kaolack et Ziguinchor. Aujourd’hui, le secteur de la pêche sénégalaise est largement dominé par la pêche artisanale, qui constituait 90% des cargaisons totales des produits de la mer en 2006 avec 350 000 tonnes. Plus de 60% des produits de la pêche artisanale sont destinés à l’exportation et la transformation. En 2006, le secteur dans son ensemble représentait 9% du PIB du secteur primaire, 1.5% du PIB total, et 1/3 des devises étrangères (250 millions de dollars par an). Plus importante que le poids économique du secteur, est son poids social : la pêche génère indirectement 600 000 emplois, dont 67% au sein du secteur artisanal. En outre, les produits de la pêche comblent les besoins en protéines animales de la population sénégalaise à hauteur de 75%1. La pêche a connu une expansion spectaculaire au cours des dernières décennies grâce à l’impulsion de politiques publiques de développement basées sur une logique sectorielle productiviste. Une flotte nationale artisanale et industrielle a été progressivement mise en place ainsi que de fortes capacités de transformation industrielle. Cet engagement de l’Etat a ensuite connu un net ralentissement du fait, entre autre, des politiques d’ajustement structurel. Le renchérissement des coûts de production subséquents à la dévaluation du franc CFA en 1994 a lourdement affecté les pêcheurs. Parallèlement, avec la forte demande en produits halieutiques et en l’absence de politiques adéquates et cohérentes de gestion durable des ressources exploitables, une situation de surexploitation des ressources halieutiques s’est installée. En conséquence de la raréfaction des ressources halieutiques, la pêche sénégalaise traverse une crise sans précédent, dont les effets commencent à se faire sentir à tous les niveaux : appauvrissement des communautés de pêcheurs, menace de l’approvisionnement en poisson des populations, baisse des captures à haute valeur ajoutée, baisse des exportations, baisse de la rentabilité et des revenus des unités de pêche. Par ailleurs, de plus en plus d’établissements de transformation industrielle ferment (23 entreprises entre 1999 et 2006).

    Description: 1. Interactions between cetaceans and fishing activity in the Archipelago of the Azores were examined using information contained in grey literature and previously unpublished data collected by observer programmes and research projects from 1998 to 2006. Together with a brief description of the economics, gear, fishing effort, and past and ongoing monitoring projects, levels of cetacean bycatch and interference were reported for each major fishery. 2. Cetaceans were present in 7% (n=973) and interfered in 3% (n=452) of the fishing events monitored by observers aboard tuna-fishing vessels. Interference resulted in a significantly higher proportion of events with zero catches but it was also associated with higher tuna catches. 3. There was a decreasing trend in the proportion of tuna-fishing events with cetacean presence or interference throughout this study, as well as a reduction in the estimates of dolphins captured annually by the whole fleet. 4. Observers reported cetacean depredation in 16% of the sets for demersal species and in 2% of the sets for swordfish. Cetacean presence and depredation were associated with higher overall catches and higher catches per unit effort in demersal fisheries. Bottlenose dolphins (Tursiops truncatus) were responsible for most depredation events in demersal fisheries, whereas in the swordfish fishery, depredation was associated with the presence of killer whales (Orcinus orca). There were no reports of cetacean bycatch in these fisheries. There were also no reports of cetaceans interacting in the experimental deep-sea fisheries that were examined. 5. Available data suggests that levels of interaction between cetaceans and Azorean fisheries are generally low and that the economic impact of cetacean interference is probably small. However, for several traditional fisheries there are no accurate data to determine levels of cetacean interaction. We recommend that existing observer programmes be expanded to increase observer coverage of the demersal and swordfish fisheries and allow monitoring of other existing and emerging fisheries.

    Description: The longfin squid Loligo pealeii is distributed widely in the NW Atlantic and is the target of a major fishery. A previous electrophoretic study of L. pealeii was unable to prove genetic differentiation, and the fishery has been managed as a single unit stock. We tested for population structure using 5 microsatellite loci. In early summer (June), when the squids had migrated inshore to spawn, we distinguished 4 genetically distinct stocks between Delaware and Cape Cod (ca. 490 km); a 5th genetic stock occurred in Nova Scotia and a 6th in the northern Gulf of Mexico. One of the summer inshore stocks did not show genetic differentiation from 2 of the winter offshore populations. We suggest that squids from summer locations overwinter in offshore canyons and that winter offshore fishing may affect multiple stocks of the inshore fishery. In spring, squids may segregate by genetic stock as they undertake their inshore migration, indicating an underlying mechanism of subpopulation recognition.

    Description: No-take marine reserves are widely recognized as an effective conservation tool for protecting marine resources. Despite considerable empirical evidence that abundance and biomass of fished species increase within marine reserve boundaries, the potential for reserves to provide fisheries and conservation benefits to adjacent waters remains heavily debated. This paper uses statistical and population models to evaluate published empirical data on adult spillover from marine reserves and shows that spillover is a common phenomenon for species that respond positively to reserve protection, but at relatively small scales, detectable on average up to 800 m from reserve boundaries. At these small scales, local fisheries around reserves were likely unsustainable in 12 of 14 cases without the reserve, and spillover partially or fully offsets losses in catch due to reserve closure in the other two cases. For reserves to play a role in sustaining and replenishing larger-scale fished stocks, networks of reserves may be necessary, but as few exist this is difficult to evaluate. The results suggest reserves can simultaneously meet conservation objectives and benefit local fisheries adjacent to their boundaries.
