| 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... |

| (1). During 1995 an estimated total of 4313 tonnes of fish was landed on Mahe. Praslin and La Digue by 337 fishing boats 86,4% of which was landed on Mahe alone. The catch volume has decreased by 114 tonnes since 1994, and the number of boats operating has increased by 9 over the same period. (2). The most important species groups landed (greater than 5% of the total catch) were, carangues {29.8%), job (13.3%), bourgeois (8.3%), maquereau doux (7.5%), cordonicr (6.8%) and capitaine (6.8%). (3). Peak landings occurred in March (546.6 MT) and the lowest catch occurred in January (216.4 MT). The average catch per month was 359.4 tonnes. (4). A marked seasonal variation in catches of demersal species was observed, with low catches being recorded during the... |

| Le Centre National de Recherches Oceanographiques et des Pêches de Nouadhibou (CNROP) entreprend chaque semestre un recensement exhaustif des unités de pêche artisanale opérant sur le littoral mauritanien. En juillet 1987 une enquête socio- 6conomique a été effectuée. Les informations recueillies portent sur les pirogues en état de prendre la mer, les migrations de pêcheurs, l'emploi et l'activité au cours des trois derniers mois,le capital technique, les équipages et l'organisation sociogconomique des unités de pêche. La pêche artisanale mauritanienne compte actuellement 735 embarcations réparties sur 22 points de débarquement. Elle génère 3302 emplois directs. |

| (1). During 2003 a total of 3,852 Metric Tonnes (MT) of fish was landed on Mahe, Praslin and La Digue by 405 fishing boats. 80.5% of the total catch was landed on Mahe alone. The total artisanal catch decreased by 1063 (MT) compared to 2002, whilst the number of boats operating increased by 31 over the same period (excluding sport fishing vessels). (2). The most important species groups landed (greater than 5% of the total catch) were carangues (33.6%), job (15.8%), bourgeois (9.1%), cordonier (6.6%), capitaine (6.1%), becune (6.0%), and maquereau doux (5.4%). Compared to 2002, there were notable increases in the relative importance of cordonier and bourgeois to the overall catch. (3). Peak landings occurred in November (463.7 MT) and the lowest catch was... |

| Abstract—In collaboration with local stakeholders, Frontier-Tanzania is collecting biophysical information to facilitate effective management initiatives for Misali Island, where marine resource management is currently limited to a 1.4-km2 non-extraction zone within a 21.6-km2 conservation area. In the study reported here, the extraction and non-extraction zones at Misali Island with similar substrata were compared. Data analysis showed a significant disassociation in both abundance and mean length patterns of fish families found in each zone. Further analysis using t-tests on individual families showed that some groups were significantly more abundant in either zone, but without significant differences of mean lengths. Fish family abundance and length... |

The catch volume has decreased by 498.9 tonnes since 1991 The number of boats operating has decreased by 3 since 1993. (2). The most important species groups landed (greater than 5% of the total catch) were, carangues (24.1%), job (13.6%), maquerau doux (13.2%), bourgeois (6.8%) and capitaine (6.4%). (3). Peak landings occurred in March (619.7 MT), the lowest catch occurred in February (172.0 MT). The average catch per month was 368.9 tonnes. (4). A marked seasonal variation in catches of demersal species was observed (snappers, job, vielle) with... |

| Monte Hermoso (Province of Buenos Aires, Argentina) is a tourist town inhabited by a large number of artisanal fishermen. The aim of this study was to characterize, through a descriptive analysis, the operational activity of the artisanal fleet and quantify the catches landed per species. The ships, of a trucker type, are 6-9 m length equipped with a 40-90 HP outboard motor. The data analyzed derive from purchase slips furnished by a gatherer corresponding to the November 2009-October 2010 period. The target species were stripped weakfish (Cynoscion guatucupa) and patagonian smoothhound (Mustelus schmitti). The former was caught with hand line throughout the year, essentially between September-December. The latter was fished during March-April and... |

| Durante 1994 el chivo mapalé (Cathorops spixii) fue el segundo recurso pesquero más abundante en la Ciénaga Grande de Santa Marta y el Complejo de Pajarales, principal sistema laguno-estuarino de Colombia. A partir de estadísticas de capturas comerciales y prospecciones pesqueras, se determinaron los parámetros básicos de su población: ciclo reproductivo, crecimiento, mortalidad, rendimiento y biomasa por recluta. Se presentaron individuos maduros durante todo el año con un pico de maduración y desove de junio a agosto cubriendo las épocas de lluvia menor y seca, respectivamente. La talla media de madurez se estimó en 23 cm. Los parámetros de crecimiento de la función de von Bertalanffy fueron: L¥ = 32.5 cm y K = 0.38 año-1, en tanto que el índice de... |
