This review examines the contribution of research on fishes to the growing field of
behavioural syndromes. Current knowledge of behavioural syndromes in fishes is reviewed …

The study of sex differences has produced major insights into the organization of animal
phenotypes and the regulatory mechanisms generating phenotypic variation from similar …

Alternative reproductive tactics (ARTs) coexisting within a population are found in many
organisms. Their existence has been an enduring puzzle in evolutionary biology. Why …

Not all stress is stressful; instead, it appears that stress in the environment, below the
mutation threshold, is essential for many subtle manifestations of population structures and …

Female–female aggression often functions in competition over reproductive or social
benefits, but the proximate mechanisms of this apparently adaptive behaviour are not well …

The aim of this review is to assess the ethical implications of finfish aquaculture, regarding
fish welfare and environmental aspects. The finfish aquaculture industry has grown …

Highlights•The phenotypic gambit is a useful heuristic for behavioural ecology.•Genetic
mechanisms can also illuminate studies of adaptive significance.•Genomics provides …

There is a considerable public and scientific debate concerning welfare of fish in
aquaculture. In this review, we will consider fish welfare as an integration of physiological …

There is increasing evidence that the genetic architecture of exploration behavior includes
the dopamine receptor D4 gene (DRD 4). Such a link implies that the within‐individual …

Fishes have radiated throughout all aquatic environments, and this is reflected in an
extraordinary diversity of mating systems and reproductive behaviors. Many species present …
