| Tuna world fisheries yield 3 million tons per year; the increase rate of whole production is constant and sustained since 30 years. This original figure for marine fisheries is due to enlargement of tuna fleets and fishing grounds over all the world ocean, the continuous increase of tuna fishing power by in board equipment and remote sensing equipment for searching and scouting (on board, aircraft, satellite, telecommunication_). During the last 20 years, the log-associated tuna fishing has contributed to the local individual and tuna fleets efficiency and fishing power either for large industrial tuna seiners by radio-equipped buoys on natural (debris) or artificial man-made logs. The same trend is noted for numerous artisanal tuna and large pelagic... |

| Con la activa participación del sector industrial pesquero, se evaluaron los efectos biológicos y económicos de cambios tecnológicos en redes de arrastre para camarón en aguas someras del Pacífico colombiano en términos de reducir la fauna acompañante y el consumo de combustible. Se usaron dos embarcaciones simultáneamente en faenas de pesca experimental que compararon el desempeño de una red prototipo y de la red convencional usada por la flota, cuantificando en ambos casos los efectos del dispositivo excluidor de tortugas (DET) y de dos subáreas de pesca (centro-norte y centro-sur). Las variables de desempeño pesquero usadas para evaluar el efecto de cambios en la tecnología de pesca sobre la captura objetivo (CO) y la fauna acompañante [captura... |

| Following the trials conducted in 1958/59 by German trawlers, the I.S.T.P.M. tested for the first time, in 1960, on the Roselys, a 120 CV oceanographic research vessel, a pelagic trawl using a boat equipped with a headrope sounder. The trawl was a double panel trawl with an opening perimeter of 500 80 mm meshes. The lateral opening was made through hydrodynamic Süberkrüb doors of 1,7 sq. meters and 130 kg. Finally, an Atlas Werke netzsonde whose oscillator was set on a platform towed behind a headrope, was transmitting information about the opening and sinkage depth of the trawl to the bridge. The cable only had one conductor and the answer was transmitted through the water. Since then, new cables with two coaxial conductors have been used and results are... |

| 3D modelling of the fishing gear flume tank at IFREMER's Lorient site Within the framework of their training, it is suggested that students in their first year of the "Industrial Product Design" BTS (vocational training certificate) at the Colbert de Lorent school participate in an internship in order to put into practice their acquired skills and to familiarise themselves with the work environment. Erwan Davigo did his internship at IFREMER's Lorient station, in the Fishing Technology department, from 18 May 1998 to 26 June 1998 (placement supervisor: Gérard Bavouzet). The study topic focuses on modelling the Lorient station's test basin in three dimensions, thus making it possible to complete the documentation base. IFREMER is presented in its entirety... |

| This study examines the occupational characteristics and technology options of capture fisheries in Ogun Waterside Local Government Area of Ogun State. Data were collected from respondents selected randomly from four fishing communities in the local government using questionnaires. Descriptive statistics were used to analyse the data. Most of the respondents are male, aged above 30 and had minimal education. Lagoon fishing is the most common and there was an inverse relationship between fishing water distance and frequency of fisher folk plying the route. Non-motorized fishing technologies were used by most of the respondents. The significant variables in the regression analyses are fixed production costs and high sea fishing. Recommendations centered on... |
