| The Colombian deep sea shrimp fishery is carried out by vessels with double bottom trawl fishing gear. There is a wide variety in the catch composition species, in which many of them have a wide distribution depth range. Fifty four fish species of 35 families, 11 crustacean species of 11 families, and one mollusk species were identified. Some holothurians, gastropods, echinoderms and other mollusks also appeared occasionally. The joint analysis of the current and former studies determined 85 species in the catch composition of this fishery. The Colombian bottom trawl fishery is actually using the turtle excluder device as the only technical adaptation of the fishing gear to reduce the bycatch turtles, but seems to exclude other big size commercial bycatch.... |

| There is increasing evidence from previous studies, and from fishers' observations, that coastal dolphins use fishing nets as an easily accessible feeding source, damaging or depredating fish caught in the nets. This study investigates the impact of dolphin depredation on artisanal trammelnets by analysing the catch composition of 614 artisanal fishing operations in the Bonifacio Strait Natural Reserve (France). Common bottlenose dolphins (Tursiops truncatus) attacked, on average, 12.4% of the nets and damaged 8.3% of the catch. However, attacked nets were characterized by statistically significantly higher catch per unit effort than unattacked ones. Catch composition also differed significantly after dolphin attacks; bentho-pelagic fish were more... |

| This work characterizes the composition and dynamics of the incidental catch in the patagonian shrimp (Pleoticus muelleri) fishery, with special emphasis on the bycatch of common hake (Merlucius hubbsi). The Observer Program coordinated by the Chubut Province (Argentina) and used to monitor the fishery is evaluated. The factors that explain the variability of hake bycatch rates are analyzed, different statistical estimators are evaluated and possible strategies for controlling bycatch are discussed. The study is centered on the double-otter-trawl freezers, responsible for 75 percent of the Argentine shrimp landings. This fleet operates in San Jorge Gulf, in waters under the jurisdiction of the provinces of Chubut and Santa Cruz, and in waters of the... |

| (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... |

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).

| Ce travail décrit les résultats de la campagne de pêche benthique dans le golfe de Tunis. Durant la campagne de 1999, les ressources benthiques du golfe sont exploitées par 45 chalutiers. Ces unités ont enregistré une production de 590 tonnes qui est voisine à celle de deux années précédentes. Les débarquements sont constitués essentiellement de merlu Merluccius merluccius , rouget blanc Mullus barbatus, saurel Trachurus sp., chevrette Parapenaeus longirostris, pageot Pagellus sp. et spicarel Spicara sp. Le chalutage expérimental dans le golfe a donné un rendement horaire de 45Kg et un pourcentage de rejet évalué à 16%. L'étude des structures démographiques des principales espèces montre que l'exploitation dans le golfe s'effectue sur des groupes d'âge... |

| During 2008, a total of 4777 MT of fish was landed on Mahé, Praslin and La Digue by approximately 400 fishing boats. 81% of the total catch was landed on Mahé. The total artisanal catch increased by 593MT compared to 2007, whilst the number of boats operating increased by 49 units over the same period (excluding sport fishing vessels). The most important species groups landed (greater than 5% of the total catch) were carangue (25.7%), bourgeois (17.7%), job (15.8%), capitaine (7.1%), and macquereau doux (6.1%). Peak landings occurred in May (567.1 MT) and the lowest in June (219.2 MT), the latter period coinciding with the Southeast (SE) Trades and sea states not conducive to fishing. The average monthly catch in 2008 was 398.1 MT, representing an increase... |

| Se presentan los resultados del seguimiento de la pesquería del recurso concha realizado en el año 2008. Los puertos de Hualtaco y San Lorenzo registraron los más altos desembarques (6 667 617 y 5 959 595 conchas, respectivamente). El esfuerzo promedio máximo se presentó en San Lorenzo (320 recolectores/día pesca) y el mínimo en Puerto Jelí (50 recolectores/día pesca); mientras que la captura promedio de conchas (CPUE) más alta se registró en Puerto Jelí(136 conchas/hombre/día de pesca)y la menor en Muisne (100 conchas/hombre/día de pesca). El porcentaje de conchas por debajo de la talla mínima legal (45 mm Lt) tanto de concheros y comerciantes es superior a 55% en cada puerto de desembarque. Respecto a la condición reproductiva, se obsevó gran... |

| Durante el 2004 se realizó el seguimiento del recurso concha en los principales puertos de desembarques de la costa ecuatoriana. Se estimó las capturas promedios mensuales en cada puerto, registrándose en San Lorenzo desembarques superior a 1000 000 conchas, en contraste con puerto El Morro que registró los valores más bajos (alrededor de 50 000 conchas). A nivel de esfuerzo y captura por conchero, San Lorenzo registró los valores promedios más altos (284 concheros/día/pesca y 196 conchas/pescador/día, respectivamente). En la proporción de especies en los desembarques comerciales predominó A.tuberculosa en una relación 3:1 con respecto a A. similis. En la mayoría de los puertos se registró el predominio de conchas menores a 45 mm (talla legal), siendo... |

| En Ecuador se han reportado cuatro especies de pinchagua: Opisthonema bulleri, O. libertate , O. medirastre, O. berlangai, difíciles de distinguir a través de sus características morfológicas externas durante los desembarques, por lo que para estas investigaciones se las ha agrupado a nivel de género (Opisthonema spp.). Su captura se la destina para la elaboración de enlatados, prohibiéndose su utilización para la elaboración de harina de pescado. Se ha registrado una considerable declinación de este recurso a partir de 1985, hasta llegar a un mínimo desembarcado de 6 895 t durante el 2003; en el 2009 acumuló 22 528 t. El rango de longitudes fluctúa entre 9 y 33 cm LT. Por lo general, un gran porcentaje de los individuos capturados no alcanzan la talla... |
