This study provides a better knowledge regarding to the current status of one major component of the bycatches Otolithes argenteus （O. argenteus） caught in the shrimp fishery area along the West coast of Madagascar using the morphometric analysis. Individual body weight and body measurement were carried out on 565 specimens collected from the sale＇s society of seafood （SOPROMER） in the Capital city. Results show a high proportion of small fishes like as immature young individuals. A ＂negative allometry＂ growth type within the juveniles to become ＂isometric allometry＂ for the adult, large size was observed. Marine environment is favorable to the development for the whole population of the O. argenteus species. The morphometry approach helped to better understanding of the characteristics and the operating status of the O. argenteus population thus constitute as a tool in establishing a sustainable fisheries management strategy in Madagascar.展开更多
