Sea Bream Juvenile Welfare in Hatchery Systems

Welfare science for juvenile gilt-head sea bream in Mediterranean hatchery and nursery systems.

Key Facts

Juvenile sea bream welfare in hatcheries is critical for establishing healthy populations
Crowding in larval tanks causes chronic stress and developmental abnormalities
Jaw and skeletal malformations in juveniles are welfare and production concerns
Weaning to artificial diets is a welfare-challenging transition for larval fish

Welfare Considerations

Hatchery welfare for juvenile sea bream establishes the welfare baseline for the entire production cycle. Crowding, water quality fluctuations, and weaning stress in early life cause chronic welfare compromise and long-term consequences for disease susceptibility. Welfare-informed hatchery management maintains low larval densities, optimises water quality, and transitions juveniles to artificial diets gradually.
