La pesca recreativa es una variedad turística practicada alrededor del mundo, siendo cada vez más preferida la captura y liberación. Pocos estudios han sido realizados sobre las pesquerías recreativas en Cuba y ninguno enfocado a las características socio-económicas de la misma. Los objetivos del presente trabajo son (1) caracterizar socioeconómicamente las pesquerías recreativas en Jardines de la Reina y (2) evaluar la percepción de los visitantes sobre la conservación de los recursos naturales del área. Para ello fueron encuestados 93 pescadores recreativos procedentes de 13 países, fundamentalmente de Reina Unido, Canadá, Argentina y Estados Unidos. La muestra fue dominada por hombres, con edades entre 41 y 50 años, casados y graduados... |

The activity of fishing fleets for hake Merluccius hubbsi south of 41°S Argentine Sea, SW Atlantic, is described. In order to establish the standard group of vessels, density indices derived from research cruises and ice-chilling fleets were related. Group four 1,400-1,800 HP related better to the abundance trend. Also, two series of indices associated to different fractions of the population were estimated: juveniles age 2) and adults age 3-5. Finally, a total catch per unit effort CPUE for the region south of 41°S, which showed a declining trend during the period considered 1991-1997, was calculated. |

Analyzed in this paper is the structure of the fleet applied to mackerel fishing based at Mar del Plata Port (38° LS); an attempt is also made at establishing the best system for measuring the fishing effort; the changes in catch capability (availability and vulnerability)are duly analyzed. Sampling vessels that allow greater data, particulary by in relation to the fishing effort, are available since the 1983/84 fishing season. |

Durante el período abril 2009 – 2010 se analizó la situación pesquera artesanal del recurso guariche o cangrejo rojo Ucides occidentalis (Ortmann, 1897) en el estuario del Río Chone, considerando desembarques comerciales y su hábitat “in situ”. El esfuerzo total promedio correspondió 84 recolectores/día pesca, con una captura promedio de 36 cangrejos o su equivalente a 6 sartas u atados. Se registró un 90% de ejemplares macho con talla promedio de 7.5 cm de ancho cefalotorácico (AC); mientras que el 10% de ejemplares hembras presento una talla promedio de 6.5 cm AC. El muestreo de densidad poblacional se lo realizo en 36 estaciones correspondiente a las seis localidades cangrejeras ubicadas en el estuario reportando una densidad de 0.7 cangrejos/m2.... |

Se presentan los resultados obtenidos para la tortuga carey (Eretmochelys imbricata) en la plataforma cubana, a partir de los monitoreos en los dos sitios de captura comercial: Cocodrilo (Isla de la Juventud) y Nuevitas; entre 1995 y 2006. Se analizan algunos indicadores poblacionales como el comportamiento de la composición por talla, la talla media anual y la proporción sexual de los careyes capturados, así como el comportamiento de la captura comercial anual en los dos sitios. Se concluye que la talla media de los careyes capturados en la Isla de la Juventud y Nuevitas, se ha mantenido estable a lo largo del tiempo, con un predominio de las tallas menores en la Isla de la Juventud; y que la proporción por sexos favorable a las hembras muestra un... |

Due to the general lack of targeted fisheries on billfish, the resource status of these species within the Indian Ocean has not been analysed in any previous study and currently remains unknown. Nevertheless, significant quantities of billfish are caught annually in the Indian Ocean and, being generally long lived, these species remain vulnerable to overfishing. In this paper preliminary indices of stock availability are presented for the main billfish species based on the catch and effort data pertaining to the Japanese and Taiwanese Indian Ocean longline fisheries. While the indices need to be treated with some caution (due to problems relating to the accuracy of the catch and effort data, and the fact that changes in catchability have not been factored... |

Red porgy (Pagrus pagrus) fishery. Analysis of catches, nominal effort and landings structure in 2011. A descriptive analysis of red porgy (Pagrus pagrus) fishery within the Buenos Aires Coastal Ecosystem (BCE) and the Argentine continental shelf, between 34° S and 42° S, during 2011 was performed. The catches landed, of a total of 3,627 t, performed in a direct and incidental way by an heterogeneous fleet of 149 vessels belonging to five strata (Ia, Ib, Ic, IIa and IIb) in 1,527 fishing trips represented a 36.7% decrease as regards 2010. The spatiotemporal analysis allowed to determine that the highest yields of the species were obtained close to 50 m depth, that coincides with the highest surface temperatures in the area, that decrease in a... |

An analysis was made of the factors affecting the catch rates of the yellow squat lobster (Cervimunida johni) in Chile’s northern region (26°03’-32°10’S) by reviewing commercial fishing logbooks from 1993 to 2003. Factors evaluated included years, months, depth stratum, fishing areas and fleet characteristics as linear predictors in a generalized linear model (GLM) in order to explain variability in the catch rate. In contrast with other fisheries, with this resource the technical characteristics of the fleet and its’ specialization poorly explain variations in catch rate; temporal factors and their interaction were, however, highly significant. The results of this study, together with the life history of the resource, allow the supposition that... |

Basic aspects concerning southern blue whiting (Micromesistius australis) fishing by the Argentine fleet in the period 1989-1995 are analized. Catch and effort statistics, fleet operation modalities and spatial and temporary characteristics of fishing activities are included. The basic information to perform this analysis was collected from the fishing statistics provided by the Subsecretaría de Agricultura, Ganadería y Pesca of Argentina and from reports of the Observers Program on board of the commercial fleet. It was in 1989, when the first ship for surimi production entered the fishery, that southern blue whiting catches carried out by the Argentine fleet became important. As of 1989 catches increased in a steady way to stabilize at near 100,000 annual... |

The analysis of the Argentine fishing fleet (SW Atlantic) evolution as of 1960 allows to explain the major causes of expansion, the crisis in the fisheries and the structural changes of the fleet during the 90's. Different fleet classification criteria focused on fishing capacity, fish landing composition, yields and productivity indices are described. The expansion cycles were associated to the incorporation of fishing vessels, while the 1960-1989 crisis originated in domestic and international economic crisis and changes in the strategy pattern of the fishing countries. The latter was related to overfishing of traditional coastal and demersal fisheries and to the full exploitation of resources such as squid, blue whiting and toothfish incorporated to the... |
