Última Efficiency of the bottom trawl used for the Mediterranean international trawl survey (MEDITS) 5 Fiorentini, Loris; Dremiere, Pierre-yves; Leonori, Iole; Sala, Antonello; Palumbo, Vito. The aim of the work presented in this paper was to assess the relative efficiency of the GOC 73 sampling trawl used for the Mediterranean international trawl survey programme (MEDITS) compared with that of a typical Italian commercial trawl. The latter was chosen because it is commonly used by fishermen in the central Adriatic, where the experiment was conducted, and therefore appeared as the best possible sampler of the commercial species present in those areas. Moreover, this trawl is similar to the various trawls used for the Italian national survey programme (GRUND). Four fishing trips were conducted between 1996 and 1997 in different areas and seasons to sample different species. Each trip was conducted in the same fishing area. A codend cover mounted...

A practical and simple technique which gives an aproximate solution to the determination of minimum length of warp payed out durin a demersal or botto,m trawl operation es proposed. The method takes into account such variables as: weight in the water of warp payed out, of the otter board an the maximum trawling speed determined for each vessel in particular. The FRS "Dr. E.L. Holmberg" of the National Institute for Scientific Research and Development (INIDEP, Mar del Plata)was used to test the method.

Major results and difficulties which resulted from experiences in species and per size selectivity for the Argentine fishery are described. Codend selectivity and grid sorting devices trials were carried out. The use of grids not only reduced by-catch of hake in the shrimp fishery but also improved juveniles selectivity in the hake fishery as compared to mesh selectivity. No changes in fishing gears or in fishing manoeuvres were necessary. It was concluded that, to achieve a better rational exploitation of fishing resources, it is necessary to enhance selectivity of fishing gears. Deeper knowledge and further training of crews on Argentine fleets is also encouraged.

Le présent travail concerne l’adaptation et l’essai d’un chalut pélagique japonais de très grandes mailles et à quatre faces égales dans les pêcheries tunisiennes. Le fil élémentaire composant les alèzes de filets est en Dyneema. Les essais de ce modèle de chalut, conçu pour un bateau d’une puissance motrice de 650 C.V, ont montré qu’il est adapté aux pêcheries de la région nord de la Tunisie et qu’il est efficace pour la capture des petits poissons pélagiques de grande profondeur notamment la sardine et l’anchois. Par ailleurs, les rendements de ce modèle de chalut sont importants grâce à ses ouvertures, horizontale et verticale, d’environ 35mètres. Les captures sont composées à plus de 99% d’espèces pélagiques.
