Abstract

Cora Diamond has criticized capacity-based approaches to determining the moral status of animals, arguing instead that the morally significant fact is that we have relationships to animals as our fellow creatures. This paper explores implications of her approach to fish and the practice of fish farming. Fish differ from most other animals due to their appearances and under-water existence, and it is not obvious that fish belong to our fellow creatures, and – if so – what it means for our treatment of them. In particular: if fish are fellow creatures, can we treat them in the way done in contemporary salmon farming ? Iris Murdoch points out that moral differences are conceptual differences, that is differences in how we see the world. Similarly, Diamond argues that we should not consider ‘animal’ or ‘human’ as biological classifications – they are conceptual configurations that shape the way we think and make sense of the world. In this article, we explore the implication of the fellow creature concept for the case of fish, which challenge our ordinary understandings of companionship with animals. We argue that farmed salmon should be consibdered as a special kind of fellow creatures living in water, and discuss how scientific research on biological features of fish may influence how we see them. We also sketch how Diamond’s approach implies a need for reform of current salmon farming practices.
