| Abstract |
European sea bass, Dicentrarchus labrax L., is an important commercial species along the Atlantic and Mediterranean coastline in both fishing and aquaculture. The artificial propagation of this species may lead to reduced amounts of genetic diversity. Although many biological topics related to the aquaculture of this species have been studied, information on the amount and distribution of genetic variation throughout the range of the species is scarce. In the present study, the investigation of the genetic resources of the sea bass along the Spanish littoral, initiated by Martinez et al. (1991), was extended to a survey of a cultivated Mediterranean population. Allozymes were analysed and the variations were estimated. Any detectable change in genetic structure, potentially caused by rearing conditions, was assessed and compared to previously analysed populations in the Atlantic and Cantabric. |
