Histology of reared and wild European sea bas (Dicentrarchus labrax)

Sea bass (Dicentrarchus labrax) is the most important marine species reared in the Mediterranean region. There are several technological procedures in the fish culture process which may result in either acute or chronic stress. High stocking density, handling, temperature fluctuations and poor water quality are common stressors in intensive fish culture. Nutritional status is considered one of the most important factors that determine the ability of fish to resist diseases. Production of sea bass is nowadays a well-controlled process, but knowledge of its nutritional requirements is still very limited. The aim of this study was to determine the effects of intensive culture on the histological picture of the liver, spleen and kidney in comparison to the fish from the wild population.The results of the present study indicate that the intensive culture of sea bass results in the changes of liver, spleen and kidney histological picture. Further examinations are, however, required to determine the specific effects of the intensive culture process (commercial diet, stocking density and various technological aspects) on histological picture of sea bass tissues.
