Sturgeon are among the world's most critically endangered fish, decimated by overfishing, habitat loss, and caviar demand. Their welfare as long-lived, slow-reproducing species makes recovery extremely time-sensitive.
Sturgeon welfare presents unique challenges rooted in their extraordinary biology. As long-lived, slow-reproducing species, the loss of individuals has compounding welfare and conservation consequences — each poached adult represents decades of growth and reproductive potential eliminated. Captive conservation breeding programmes must meet the welfare needs of animals that evolved in large, free-flowing rivers — providing adequate space, appropriate water quality and temperature, and minimising handling stress. Wild sturgeon welfare is threatened by river barriers that prevent migration to spawning grounds, causing reproductive failure without apparent mortality. Dam removal and fish passage infrastructure directly improve sturgeon welfare and population recovery prospects.
