Many fish species face increasing challenges associated with climate change and overfishing. At the same time, aquaculture is becoming vital for food security. Gaining a deeper understanding of the basic biology of fish is therefore more important than ever. Here we synthesize and summarize key questions, opportunities and challenges in fish biology highlighted during a round‐table discussion at the 50th Anniversary Symposium...

This study tested for links among behaviour, state and life‐history variables as predicted by the pace‐of‐life hypothesis in adult pike Esox lucius. First, a standardized open‐field behavioural assay was developed to assess individual behaviour of wild‐captured adult E. lucius . Behaviour within the standardized assay predicted swimming behaviour in the lake, providing an ecological validation of the assay. There was no relati...
