Head-start programs for sea turtles raise hatchlings through their most vulnerable early life stage in captivity before release, with significant welfare implications for both effectiveness and individual animals.
Head-start programs represent a genuine welfare tension: individual animals held in captivity experience confinement stress and behavioral restriction, but have dramatically improved survival prospects. The welfare calculus is complicated by uncertainty about whether raised turtles retain natal beach imprinting needed for reproduction. Modern programs have substantially shortened captive periods to balance improved survival against reduced behavioral competence.
