Fisheries can alter the timing of spawning and migration in fish

Fishing can substantially alter when fish migrate and when they breed, says a new review in Fish and Fisheries by SAFS student Michael Tillotson and faculty member Thomas Quinn. For example, fishing closures may increase fishing on late breeders, resulting in a greater proportion of early breeders in the population. Such changes can exacerbate the effects of climate-driven changes in the timing of migration and breeding.
