Shark Welfare in Fisheries and Research

Sharks in commercial fisheries and recreational angling face welfare challenges that are rarely discussed given focus on conservation.

Key Facts

Shark stress responses cause lactic acid build-up that can be fatal after capture and release
Post-release mortality in sharks can reach 50-80% depending on handling time and method
Sharks in aquaria show significant welfare challenges due to their large ranging needs
Pelagic sharks including great whites have never been held successfully in captivity long-term

Welfare Considerations

Individual shark welfare in fisheries is complicated by the scale of capture and the difficulty of humane handling for large, active predators. Sharks that survive initial catch may die from post-release physiological stress even when visually healthy at release. Research on shark stress physiology is advancing understanding of minimum handling requirements to improve post-release survival.

What You Can Do

Support catch-and-release shark angling guidelines that minimize handling time
Advocate for rapid handling time standards in shark catch-and-release fisheries
Support research into handling practices that improve shark post-release survival
Choose aquaria that do not attempt to hold large pelagic shark species in captivity
