Contract nr: QLK5-CT-2000-31365
Project type: RS (Research and Technological Development Project)
Starting date: 01-01-2001

Research topic: 5.1.2. Sustainable fisheries and aquaculture

Abstract:
PROBASS addresses the problem faced by sea bass aquaculture, due to the fact that under culture conditions most of the fish (70-99%) are males. Males grow slower than females and weigh up to 40% less at harvest, which reduces their market value, or requires them to be cultured longer, which increases production costs. Thus, a highly desiderable goal for sea bass aquaculture is the objective of PROBASS: to develop methods to control sex differentiation to reduce unwanted males and increase females. Since environmental factors can influence sex ratios in fish, including the sea bass, PROBASS will investigate hormonal, biochemical and molecular parameters to understand the regulation of sex differentiation, and develop an environmental, hormone-free, feminisation protocol based on temperature, and density manipulations. Female-dominant stocks will result in more efficient production and increased profitability for the aquaculture of sea bass.
