Sturgeon farming for caviar production raises significant fish welfare concerns — including long production cycles, surgical egg extraction, and the inadequacy of current welfare standards for this ancient fish family.
Sturgeon welfare in farming systems is poorly understood and largely unregulated. Their long lifespans mean that welfare shortcomings — such as barren tank conditions, poor water quality, or handling stress — accumulate over many years. Traditional lethal caviar extraction causes death after years of captivity; even "humane" extraction methods involve hormonal manipulation and repeated handling stress. The sentience evidence base for fish is growing rapidly, and sturgeon — with their complex sensory systems and long lives — are increasingly recognised as deserving of specific welfare protections. Consumer demand for ethically sourced caviar should drive improvements in farm standards.
