Beluga sturgeon, the source of the world's most prized caviar, have declined by 90% from overfishing and habitat loss and now face possible extinction without emergency international conservation action.
Beluga sturgeon are extraordinarily long-lived fish whose welfare encompasses decades of ocean life before reaching the reproductive age targeted by poachers. Fish killed before reaching reproductive maturity represent not only welfare harm but lost reproductive contribution to an already severely depleted population. The cognitive and behavioral complexity of these giant fish is not well studied, but their longevity and sensory sophistication suggest welfare consideration beyond typical fish species. Legal aquaculture caviar production provides welfare benefit by reducing pressure on wild individuals while the slow recovery proceeds.
