Abstract

The aim of this study was to investigate the influence of both facility location and typology of fish farm on some ecotoxicological, qualitative and reproductive variables in European sea bass Dicentrarchus labrax L. Several variables were investigated: gonado-somatic index (GSI), liver-somatic index (LSI); 7-ethoxyresorufin-O-deethylase (EROD), benzo(a)pyrene monooxygenase and acetylcholinesterase activities; glutathione (GSH), testosterone, 17β-estradiol, total lipid, phospholipid (PL) and triglyceride contents. In addition, the histological sections of gonads were examined. Results suggest that LSI, EROD activity, GSI, GSH, PL, hormone levels and gonad morphology were influenced by different facility locations and typologies of fish farm.
