Length composition data of narrow-barred Spanish mackerel, Scomberomorus commerson (Lacepede 1800), landed between April 2002 to March 2004, were monthly used to estimate the growth, mortality and exploitation parameters of the stock. Maximum fork length and weight were 170 cm and 38 kg, respectively. Nonlinear least square fitting provided a complete set of von Bertalanffy growth estimates: L&...

Though the narrow-barred Spanish mackerel ( Scomberomorus commerson ) is considered to be migratory, species nevertheless thought locally overexploited in northwest Indian Ocean. At regional level, this local depletion a major concern for food security. As population structure and connectivity between sub-populations are poorly understood species, we examined spatio-temporal dynamics of via ele...

The genus Scomberomorus , with 18 nominal species, sustains a significant heterogeneous fishery throughout its range. sole molecular systematic study of this concerned the species group S. regalis which contains new world taxa. diversity in northern Indian Ocean has not been studied at level, often leading to misidentifications. Here, novel genetic data are provided that reconfigure boundaries ...

Museum specimens are often the only source of genetic material for many species of cetaceans. Most of the protocols that have been developed to extract DNA from teeth and bone samples involve mechanical or chemical disintegration of the material. An alternative method to the mechanical reduction process is presented here for 212 Commerson’s dolphin (Cephalorhynchus commersonii) samples collecte...

The purpose of this study was to determine and compare the concentrations of six toxic metals (Cd, Pb, Fe, Cu, Zn, Mn) in the muscle and hepatic tissues of five commercially important fish species including narrow-barred Spanish mackerel, Scomberomorus commerson, Black pomfret, Parastromateus niger, Silver pomfret, Pampus argenteus, blackspot snapper, Lutjanus fulviflammus and Tigertooth croake...
