SERUM BIOCHEMISTRY OF FARMED BLUEFIN (Thunnus thynnus L.) IN THE AEGEAN SEA

Abstract

Values of blood biochemistry are important for all animals in terms of health and welfare, providing knowledge of evidence in diseases. One of the most economically important fish species bluefin tuna-BFT (Thunnus thynnus L.) in aquaculture considering high prices in the related business. Accordingly, farmers care about fattening fishes and some analyses provide significant knowledge, especially blood analyses for them. In the study, blood samples were recovered from fishes (10 male and 12 female) in fattening farms at Ildır, Çeşme, İzmir province, East of Aegean Sea. . Results during the fattened period in growing cages indicates that BFTs were under pressure and stress attacks because of unnatural habitats such as feeding, narrow area etc. in farm area. Also, males were more sensitive and undergo more stress than females.
