Aquaculture Welfare

Farmed Sturgeon Welfare and Caviar Production

Farmed sturgeon for caviar production face welfare challenges particularly around the traditional egg harvest which requires killing the fish.

Key Facts

Sturgeon can live over 100 years and are extremely slow to mature sexually
Traditional caviar production requires killing females to harvest eggs
Non-lethal extraction methods using ultrasound and gentle stripping are increasingly available
Sturgeon show stress responses to handling and crowding
Farming sturgeon for decades before harvest creates long-term welfare management challenges

Welfare Considerations

Sturgeon aquaculture involves one of the longest-lived fish in any farming system, with welfare management required over decades. Traditional lethal egg harvest wastes the fish after years of farming. Non-lethal caviar extraction using ultrasound imaging and gentle stripping maintains broodstock welfare while enabling multiple harvests - a welfare improvement that also has commercial benefits.

What You Can Do

Choose caviar from producers using non-lethal extraction methods
Support welfare standards for sturgeon aquaculture
Advocate for fish welfare legislation that covers long-lived aquaculture species
