Cultured Atlantic salmon spend the first part of their life in freshwater and then following a physiological adaption phase called smoltification, the fish (now termed smolts) are transferred to sea cages for growout. A proportion of smolts fail to thrive after transfer, show slow or no growth and usually die some months later. This project will investigate the role that the neurohomones that control both appetite and physiological stress in fish have in stimulating the resumption of feeding after sea water transfer.The basic knowledge generated will be used directly in development of strategies for minimising smolt failure in Atlantic salmon aquaculture.

养殖的大西洋鲑鱼在淡水中度过其生命的第一部分，然后经过称为小鲑鱼化的生理适应阶段，鱼（现在称为小鲑鱼）被转移到海水网箱中进行生长。一部分小鲑鱼在转移后无法生长，生长缓慢或没有生长，通常在几个月后死亡。该项目将研究控制鱼类食欲和生理应激的神经激素在刺激海水转移后恢复摄食方面的作用。所产生的基础知识将直接用于制定尽量减少大西洋鲑鱼养殖中小鲑鱼衰竭的策略。
