| Durante el 2009, se realizó el seguimiento de las capturas de cangrejo rojo (Ucides occidentalis), en las principales localidades de extracción de la provincia de El Oro y Guayas, la captura total estimada de cangrejos fue de 2 897 707 y 3 184 795 en las provincias mencionadas. Las localidades de Puerto Jelí y Puerto Baquerizo Moreno fueron las de mayor desembarque, lo que está relacionado directamente con el esfuerzo. La CPUE fue muy variada en los puertos monitoreados con valores que oscilaron entre 47 a 94 cangrejos hombre-1 día-1, obteniéndose mayores niveles en el periodo posterior a la época de veda. La distribución de tallas de amplitud del cefalotórax de los cangrejos capturados, en cada una de las localidades muestreadas, fue superior a la talla... |

| Chub mackerel (Scomber japonicus) landings corresponding to November 2003-January 2004 and November 2004-January 2005 fishing seasons were analyzed at the Mar del Plata port (Argentina, SW Atlantic). Fourty one samples were taken to measure total length exclusively and 4 sub-samples to record individual data (total length, weight, sex, sexual stage, age according to otoliths reading). Total length ranged 20-50 cm (1 and 8 years old). The most abundant sizes, between 32-37 cm, corresponded to ages 3 and 4, respectively. Most of the fish caught were adult (95%) and mature (85%) specimens. Length-weight, length-age relations were calculated and length-growth, weight-growth parameters estimated. The catch per unit of effort, of high variability (0-2,455 kg... |

| The evolution of argentine landings, characteristics of trawl fleets, principal ports, landings per fleet and management unit (north and south of 41°S), areas and fishing seasons are described. Main results show a continuous increase of argentine hake landings as of 1987. Freezers, that operated in the Patagonian zone along the whole year, was the fleet that most contributed to said increase while the ice chilling fleet maintained its level of landings in the period considered. During the second and third quarter of 1996 and 1997, in the north management unit, the fleet fished in the argentine sector of the Common Fishing Zone and north of 41°S. During 1996, in the south management unit, the main fishing zones for both fleets were northeast of Escondida... |

| (1). During 1999 an estimated total of 4842 Metric Tonnes (MT) of fish was landed on Mahe, Praslin and La Digue by 345 fishing boats. 88.9% of the total catch was landed on Mahe alone. The catch volume has increased by 1508 MT compared to the 1998 catch and the number of boats operating decreased by 10 vessels over the same period. (2). The most important species groups landed (greater than 5% of the total catch) were carangues (30.4%), job (17%), red snapper (10%), cordonnier (5,1%) and capitaine (5.9%). (3). Peak landings occurred in April (560.1 MT) and October (565.4 MT) and the lowest catch was recorded in August (254 MT). The average catch per month was 403.5 tonnes. (4). Seasonal variation in catches of demersal species was observed, however this... |

| Se realizó el seguimiento a los desembarques de peces pelágicos pequeños en la costa ecuatoriana durante el 2008, los cuales se incrementaron en un 11 % con relación al 2007. Las especies que aumentaron fueron chuhueco (Cetengraulis ringens), sardina redonda (Etrumeus teres), y pinchagua (Opisthonema spp) en un 96 %, 80 % y 56 %, respectivamente, mientras disminuyeron los desembarques de macarela (Scomber japonicus) en un 50 % y anchoveta (Engraulis ringens) en un 25 %, mientras que botellita (Auxis spp) disminuyó en un 23 %, debido a la poca disponibilidad de alimento en la zona donde fue capturada y a las condiciones climáticas de su hábitat. El desembarque de anchoveta fue el segundo más importante del año en términos de biomasa, lo que significa que... |

| An overview of the available information on the commercially important squid species distributed in the Argentine Sea and adjacent zones is given. It includes the most representative characteristics to identify the species and general information on their biology, distribution and fisheries. A biological sampling designis presented, with particular emphasis on the identification of sexual maturity stages. The world market of the squid resources has considerably risen in the last decades and one of the most important fishery zones is placed in the Southwest Atlantic region (Area 41, FAO), where squid represent 25. of the total landings. Illex argentinus, sustains the second fishery in volume, with landings reaching 612.000 tonnes in 1999. Other species,... |

| 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... |
