| Bathymetric changes in groundfish catch composition are analyzed, on the basis of routine reports of 106 bottom longline strings. The project was conducted from 12 December 1986 to 29 November 1987, covering areas from coastal waters to the outer shelf of the continental shelf off Argentina from 36° to 55°S. As a preliminary step to the analysis, the validity of each factor as probable explanatory variable in each area, was analyzed with consideration as to their range and variation. Obtained results show that the kingclip (Genypterus blacodes), a main objective of the project, could become one of the most profitable target species of the high-sea bottom longline, in areas along the outer edge of the continental shelf, at bottom depths slightly below 200... |

| More than ten years after its launching, an evaluation of the results of the FADs programme carried on in Reunion Island has been made. Its implementation and its impact on artisanal fishery in Reunion Island have been analysed. This analysis demonstrates that, following a continuously ascending phase, the production of fish caught on fads has reached a plateau. Parallel to the FAD-associated fishery, the longline fishery has developed since 1991. This type of fishery includes production units whose operating zone is bordering the FAD installation area. Analysing the evolution of the small longliner sector is based on general activity indicators (number of ships, production, fish selling prices). Besides, a synthesis of the interactions between those two... |

| Del 2 al 14 de marzo de 2008 se realizó el Crucero T08/03/01 durante el cual se efectuaron nueve lances de pesca entre 01°24.5’ N - 03°12.0’ S y entre 081°08.6’ W - 082°56.1’ W, empleando un palangre de superficie doradero. Oceanográficamente se determinó la profundización de la termoclina lo cual favoreció el ingreso de ATS en toda la columna de agua hasta los 40 m de profundidad, lo que explicaría las bajas capturas de dorado obtenidas. El índice de abundancia determinó una mayor efectividad de los anzuelos No. 4 y 5 en cuanto a número de organismos por lance, mientras que en relación a la talla no se observan diferencias en la captura para todos los anzuelos. La pesca incidental tuvo una incidencia mínima en lo referente a tiburones, rayas y peces óseos... |

| Del 9 al 21 de marzo de 2010, se realizó el Crucero T10/03/01 durante el cual se efectuaron 10 lances de pesca entre 01º21.39' N-03º 02.55' S y entre las longitudes 080º 32.20' W-082º 57.08' W, empleando un palangre de superficie doradero. En los lances realizados frente a Esmeraldas y Manabí, se registraron las mayores capturas, con especímenes con mayor talla y peso promedio, con una temperatura superficial promedio de 27 ºC y termoclina ubicada entre los 10 y 50 m de profundidad con la isoterma de 20 ºC, próxima a la profundidad de cala de la línea de pesca. Hacia el sur (lances 7 al 10), ubicados frente al sur de Manabí, Península de Santa Elena y Golfo de Guayaquil. Las capturas estuvieron representadas por especímenes con talla y peso promedio... |

| El presente informe resume los resultados de la pesca objetivo e incidental realizada por tres barcos palangreros extranjeros, en el periodo agosto 2008 y marzo 2009. La captura total registrada fue 782.81 de las cuales 75,3% correspondieron a pesca objetivo y 24,7% a pesca incidental. El pez espada Xiphias gladius represento el 61,8% en las capturas de pesca objetivo y el tiburón aguado Prionace glauca el 69,7% en pesca inciden¬tal. Las áreas de pesca de mayor concentración se distribuyeron en aguas internacionales frente a las costas de Peru y Chile entre los 18° y 29° Latitud Sur, y 86° y 106° Longitud Oeste. El arte de pesca utilizado fue el longline o palangre de media agua con una longitud máxima de 120 km y 1500 anzuelos tipo "J". Las tallas menores... |

| Data used to generate the tables and figures presented here are based on daily catch and effort forms (logbooks) returned from fishing vessels that are licensed to fish in the Seychelles EEZ and for purse seiners, as well as from data collected via the tuna sampling programme conducted during transshipment in Port Victoria. Sometimes there are delays in these being received at SFA, especially for longliners that often spend up to a year at sea, and for purse seiners the delays are usually during and just after the second quarter of the year when most vessels are fishing in the Mozambique Channel and are not necessarily using Port Victoria for transshipment. |

| The monofilament longline fishery targeting swordfish and tuna is practised actually in Seychelles by 8 local longliners (average length of 16 metres) and foreign longliners fishing under Seychelles licenses ( French and Indonesian longliners , averaging 34 metres and 25 metres in total length). Experimental trips by SFA’s research vessel were undertaken in 1994 and commercial trips started in 1995. The total landing catch increased from 215 mt in 1996 to 456 mt in 1999. The estimated catch rates varied from 0.64 kg/hook in 1996 to 0.92 kg/hook in 1999. Loss of catch due to predation by marine mammals (pseudorca crassidens) remains one of the major problem of this fishery. In 1999, 24 % of the total catch (109 mt of fish) was lost due to predation. The... |
