Northern pike farming is an emerging aquaculture sector with specific welfare challenges related to the highly predatory and territorial nature of this species.
Farmed pike welfare is a relatively unexplored area that reflects a broader gap in aquaculture welfare science: highly predatory species present unique challenges that standard aquaculture welfare frameworks do not adequately address. The territorial and cannibalistic nature of pike requires management interventions — size grading, density management, visual separation — that impose their own welfare costs. The dietary requirements of obligate piscivores create supply chain welfare concerns when feeder fish are used. Developing pike-specific welfare standards requires investment in basic behavioral and physiological research that currently does not exist at the scale needed for evidence-based standard setting.
