Improving production efficiency of sea bass farming by developing methodologies to eliminate environmental androgenesis

Objective

OBJECTIVES AND EXPECTED ACHIEVEMENTS
A very important problem of the European sea bass (Dicentrarchus labrax) aquaculture industry is the occurrence of 70-99% males. Male-dominant stocks are undesirable, because males exhibit reduced somatic growth compared to females, resulting in 20-40% smaller body weight at harvest. Therefore, it is desirable to culture predominantly female stocks.

The overall objective of PROBASS is to understand the mechanisms regulating sex differentiation in cultured sea bass, in order to develop methodologies to minimise the proportion of males in cultured stocks. This will result in an increase in production efficiency and profitability of the EU sea bass industry, since femaledominant stocks will reach market size earlier and produce more muscle mass. There is accumulating evidence that sex differentiation in sea bass may be under the control of complex genetic and environmental interactions.
