Broodstock management in sea bass hatcheries determines both hatchery productivity and the welfare of breeding fish, with specialised requirements for optimal outcomes.
Broodstock welfare in sea bass hatcheries is significant both as an ethical obligation and a production requirement. Chronically stressed broodstock show suppressed reproductive output and poor egg quality. Providing adequate space, appropriate environmental conditions including light management, and minimal handling stress optimises both welfare and productivity. The welfare-productivity alignment is particularly strong in broodstock management — the value of individual animals justifies higher welfare investment than would be applied to grow-out fish.
