CSBG3-stress

Offentlig prosjektsammendrag

California sea bass (CSB), is one of the most economically important species in China. Traditionally are the feeds in China based on crude values for protein and lipid, and not on digestible- protein (DP) and energy (DE). The digestible protein is the protein which the fish can digest and utilize for the biological processes like growth. A feed formulation based on DP and DE allows for a better optimization of the diet and utilization of the raw materials. In this project we are aiming to discover the optimal DP/DE level for CSB between 200-400g. High water temperature is a challenge for the farmers in China and the farmers are reporting that high lipid levels in combination with high temperature seems to make the California seabass more vulnerable for stress. The second objective of the present project is to evaluate the impact of dietary lipid level on performance and stress tolerance.
