AKUSTIKAN 1 : workshop report IRD
Petit, Didier (ed.); Gerlotto, François (ed.); Luong, N. (ed.); Nugroho, D. (ed.); Cotel, P. (collab.); Durand, Jean-René (collab.); Petitgas, Pierre (collab.).
The PELFISH project aims at a better knowlegde of the small pelagic fish stocks in Java Sea and their exploitation, the ultimate goal being as usual to build a proper management scheme. To reach this goal one needs to have minimal data on environment, liable statistic data, knowledge on biology of the main species, as well as on socio-economics. For pelagic resources, acoustic techniques represent a specific tool with is able to give useful informations. Inside PELFISH, it has been used with two main objectives : at first, repartition and extension of the pelagic resources, and then, evaluation of the corresponding biomass. It means that the studies have to take into account the hydroclimatic factors and the seasonal and interannual variations, which...

Analysis of vessel influence on spatial behaviour of fish schools using a multi-beam sonar and consequences for biomass estimates by echo-sounder IRD
Soria, Marc; Fréon, Pierre; Gerlotto, François.
Biases in the measurements of spatial distribution of fish schools and their consequences for school biomass estimates during conventional acoustic surveys are mainly due to vertical and lateral avoidance of the vessel. In this paper, we quantify school avoidance during an acoustic survey carried out from 10 to 29 May 1994 in the Catalan Sea. From a lateral multi-beam sonar the geometric characteristics (depth, length, width, height, surface, and volume) of 1268 schools were obtained. The 60 beams (1.5° X 15°) of the sonar scanned a vertical plane from 0° to 90°, perpendicular to the vessel path within a range of 100 m. Within this plane, the projected area ensonified by the echo-sounder used aboard for acoustic evaluation was evaluated to simulate a...

Biodynex workshop IRD
Potier, Michel (rapp.).
This workshop was held, from the 23th to the 25th march in Jakarta. Scientists of the project, Indonesian institutions and ASEAN countries attented this workshop (see list of participants). Under the supervision of the experts invited, some particular aspects underscored during the seminar were studied. To achieve these tasks, basic data available at the project were used and four working groups, each coordinated by an expert, were formed. After two days of analysis, the conclusions of each group were discussed during a general meeting and recommendations were given. (Résumé d'auteur)

Biologie et écologie des poissons pélagiques du lagon de Nouvelle-Calédonie utilisables comme appât thonier IRD
Conand, François.
De 1980 à 1983, près de 300 nuits de pêche ont été effectuées. Environ 10 espèces peuvent servir d'appât. Une gestion rationelle permettrait l'approvisionnement de plusieurs dizaines de canneurs. Bien que pélagiques, les espèces s'associent en fonction de la nature du fond et de la profondeur : zone coralliennes, zones côtières envasées, zones profondes. Deux types phénologiques sont rencontrés, les espèces de petites tailles sont matures à 4 à 6 cm, soit un âge de 2 à 4 mois. Leurs générations se succèdent tout au long de l'année, rapidement en saison chaude, moins vite en saison froide. Les espèces à cycle annuel, l'autre type, sont matures à la fin de leur première année. Dans les deux cas, peu d'individus survivent après la reproduction. Le mécanisme...

Biology and phenology of Amblygaster sirm (Clupeidae) in New Caledonia, a sardine of the coral environment IRD
Conand, François.
The biology of the sardine, #Amblygaster sirm$, is studied from fish caught in the lagoons around New Caledonia. About 500 fishing hauls were carried out between 1980 and 1983. This sardine is a fast-growing, medium sized fish (Lmax:24 cm) with a short lifespan. Reproduction takes place from October to December. First maturity is attained when fish reach 1 year of age and at this time their size is about 16-17 cm. Mortality is high and most fish die before the age of 2 years. This phenology compared with other seasonal spawners indicates a tendency towards semelparity. (Résumé d'auteur)

Biology of the small pelagic fishes of the lagoon of New Caledonia used as bait fish for tuna fishing = Biologie des poissons pélagiques du lagon de Nouvelle-Calédonie utilisables comme appâts pour la pêche au thon IRD
Conand, François.
Plusieurs espèces de petits poissons pélagiques sont utilisées comme appât pour la pêche thonière à la canne dans l'Indopacifique tropical. Ces poissons sont généralement capturés de nuit dans les lagons ou à l'abri des récifs, en les attirant avec de la lumière. Plus de 300 nuits de pêches expérimentales ont été réalisées entre mars 1980 et mars 1984 dans une centaine de sites du lagon de Nouvelle Calédonie et aux îles Loyauté. Une forte variation saisonnière des rendements est observée. Ils sont maximums en fin de saison chaude, en avril-mai. L'étude de la phénologie de ces poissons fait apparaître deux types. Les espèces de petite taille, à cycle court, dont la maturité est atteinte à partir de 4 à 6 cm, correspondant à un âge de 2 à 4 mois. Leurs...
