The Animal Behaviour & Welfare Group, is based at the University of Bristol's School of Veterinary Science at Langford. The group as a whole
has a diverse range of interests, from farm, domestic and companion animals to laboratory and zoo animals, captive and wild cetacea, rural wild
animals, hunted animals and reintroduced species. It also has a strong history of working on the welfare of fish. A number of members of the
group have their origins in meat research and this means that the group has a strong interest in flesh quality and its association with welfare.
In general, poor welfare will lead to poorer flesh and carcass quality thus quality is a very useful summary measure of the well being of the
fish during its life and at the time of slaughter. The fish welfare group maintains links with many national and international, commercial,
research and academic bodies focused on fish production and fish welfare.
