Sturgeons farmed for caviar production face welfare challenges from long grow-out periods, invasive egg extraction and poor regulation of a high-value but welfare-neglected industry.
Sturgeon welfare in aquaculture is poorly understood and weakly regulated despite the high value of the product and the long production timeline. Fish maintained for 10-20 years in captivity experience welfare conditions for the entirety of their productive lives — the quality of those conditions therefore matters enormously. Chronic crowding stress, poor water quality and repeated invasive procedures for egg extraction are the primary welfare concerns. The shift from kill-harvest to no-kill stripping is a welfare improvement that is gaining traction, as is the development of welfare standards for long-duration aquaculture species. Supporting certified operations and demanding welfare transparency in this high-end market can drive meaningful change.
