| 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... |

| (1). During 2002 an estimated total of 4915 tonnes of fish was landed on Mahe, Praslin and La Digue by 374 fishing boats. 83.1% of the total catch was landed on Mahe alone. The total catch increased by 625 tonnes compared to 2001, and the number of boats operating decreased by 3 over the same period. (2). The most important species groups landed (greater than 5% of the total catch) were carangues (41.5%), job (12.4%), capitaine (6.8%), becune (6.1%), maquereau doux (5.7%) and bourgeois (5.7%). (3). Peak landings occurred in October (576.5 MT) and the lowest catch was recorded in January (222.51 MT). The average catch per month was 409.6 tonnes. (4). Seasonal variation in catches of demersal species was less marked compared to previous years. The mean... |

| (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... |

| 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... |

| As part of the research programs performed yearly at the Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP, Mar del Plata, Argentina) some important basic data about the commercial fisheries usually included in internal reports are registered. This formal paper is a review and summary of size and age composition estimates of commercial catches (discards included) of Northern Argentine anchovy (34ºS-41ºS) obtained between 1990-2011. The basic data resulting from the examination of 521 samples from fishing vessels included 62,466 fish length measurements and 26,667 valid age readings from which the corresponding 22 annual age-length keys were built. The annual estimates of the individual total length-total weight relation parameters and of... |

| (1). During 1998 an estimated total of 3334.3 tonnes of fish was landed on Mahe, Praslin and La Digue by 355 fishing boats. 86% of the total catch was landed on Mahe alone. The catch volume has decreased by 716 tonnes compared to the 1997 catch and the number of boats operating has increased by 7 vessels over the same period. (2). The most important species groups landed (greater than 5% of the total catch) were carangues (30.2%), job (18.1%), capitaine (8.4%), red snappers (including bourgeois) 12.7% and barracuda (4.5%). (3). Peak landings occurred in November (507.1 MT) and the lowest catch was recorded in March (172.2 MT). The average catch per month was 277.8 tonnes this is 63.4 tonnes less on average per month than for 1997. (4). A marked seasonal... |

| 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... |

| 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... |
