Abstract:

The size structure of the commercially important rose shrimp, Parapenaeus longirostris, was compared between populations in the Sea of Marmara and the Aegean Sea. The analysis was based on data collected during trawl selectivity surveys carried out in November and December 2006. Growth showed no similar pattern, and in additions differences were found in length frequency distribution, sex ratio, and recruitment pattern of the P. longirostris populations in these two areas.

La structure de taille de la crevette rose d'importance commerciale, Parapenaeus longirostris, a été comparée chez les populations de la mer de Marmara et de la mer Egée. L'analyse a porté sur des données obtenues au cours de campagnes de contrôle de sélectivité des chaluts, menées en novembre et décembre 2006. La croissance suivait des modèles différents et de plus, des différences ont été observées dans la distribution des fréquences de longueur, dans le sex-ratio et dans le modèle de recrutement des populations de P. longirostris dans ces deux zones.
