    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: 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: 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.

    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: 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: 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).

The angular momentum of the gas is shown to display oscillations as a function of the particle number or chemical potential. This phenomenon is analogous t... [Phys. Rev.

    Description: Author(s): Igor Boettcher, Sebastian Diehl, Jan M. Pawlowski, and Christof Wetterich We derive the universal high momentum factorization of the fermion self-energy in the BCS-BEC crossover of ultracold atoms using nonperturbative quantum field theoretical methods. This property is then employed to compute the Tan contact as a function of interaction strength, temperature, and chemic... [Phys. Rev. A 87, 023606] Published Wed Feb 06, 2013

    Description: Author(s): Maxim A. Efremov, Polina V. Mironova, and Wolfgang P. Schleich We propose a lens for atoms with reduced chromatic aberrations and calculate its focal length and spot size. In our scheme a two-level atom interacts with a near-resonant standing light wave formed by two running waves of slightly different wave vectors, and a far-detuned running wave propagating pe...

    Description: Author(s): P. Hauke, R. J. Sewell, M. W. Mitchell, and M. Lewenstein We describe a technique for the preparation of quantum spin correlations in a lattice gas of ultracold atoms using an atom-light interaction of the kind routinely employed in quantum spin polarization spectroscopy. Our method is based on entropic cooling via quantum nondemolition measurement and fee... [Phys. Rev. A 87, 021601] Published Fri Feb 08, 2013

    Description: Author(s): S. Kühn and T. E. Judd We show that magnetic dipolar interactions can stabilize superfluidity in atomic gases, but the dipole alignment direction required to achieve this varies depending on whether the flow is oscillatory or continuous. If a condensate is made to oscillate through a lattice, damping of the oscillations c... [Phys. Rev. A 87, 023608] Published Fri Feb 08, 2013

    Description: Author(s): M. Grupp, W. P. Schleich, E. Goldobin, D. Koelle, R. Kleiner, and R. Walser We propose to create pairs of semifluxons starting from a flat-phase state in long, optical 0- π -0 Josephson junctions formed with internal electronic states of atomic Bose-Einstein condensates. In this optical system, we can dynamically tune the length a of the π junction, the detuning δ of the opti... [Phys. Rev. A 87, 021602] Published Wed Feb 13, 2013

We derive a separable potential to describe the low-energy scattering properties of such atoms, and use this potential to solve the mean-field dynamics during a magn... [Phys. Rev.
