Sturgeon farming for caviar production involves welfare challenges unique to this ancient fish species, including long grow-out periods and invasive harvest procedures.
Sturgeon welfare in aquaculture involves the unusual challenge of managing fish for a decade or more before they reach productive maturity - a timeframe that makes the cumulative welfare impact of inadequate conditions particularly significant. A sturgeon kept in suboptimal conditions for 10 years experiences a decade of chronic welfare compromise. Additionally, the traditional caviar harvest requiring fish slaughter raises welfare concerns that hormonal stripping methods can address, albeit imperfectly. Sturgeon farming has environmental benefits over wild harvest by reducing poaching pressure, but this conservation benefit should not obscure the need for genuinely welfare-focused farming approaches. Standards for space, water quality, and environmental complexity appropriate to these large, ancient fish are needed.
