About the Project

There has been much interest in the rearing conditions of both commercial and laboratory fishes and the welfare implications of these. Recent work has shown that enrichment of tanks with objects can be beneficial in some circumstances, but can lead to increased aggression in some species. Environmental stressors, such as alarm cue produced when fish are predated, are known to have an impact on fish behavioural and physiological responses, and these can affect subsequent generations. Other stressors, such as those experienced by fish during rearing, may also affect them and their offspring.

This project will investigate the impact of rearing conditions on fish and subsequent generations. It will use behavioural, physiological and genetic approaches to determine the impact of rearing stressors on fish and their offspring, specifically focusing on the stress response of these animals.
