Meagre Welfare in Mediterranean Aquaculture

Welfare overview for meagre (Argyrosomus regius) -- a growing Mediterranean aquaculture species with developing welfare science.

Key Facts

Meagre (Argyrosomus regius) is a large marine fish increasingly farmed in the Mediterranean
It is valued for its fast growth and excellent flesh quality compared to sea bream and sea bass
Meagre are schooling fish that show complex social behaviour -- stocking density affects welfare
They are capable of rapid stress responses -- cortisol studies confirm acute stress from handling
Meagre produce a characteristic croaking or drumming sound using their swim bladder -- a communication behaviour
High stocking density suppresses normal social and acoustic communication -- a welfare concern
Disease pressure in intensive systems includes vibriosis and nodavirus
Welfare research on meagre is less advanced than for sea bream or salmon but is growing

Welfare Significance

Meagre aquaculture welfare is an emerging field. As a large active social fish capable of acoustic communication, meagre have behavioural complexity that intensive aquaculture may compromise. Applying precautionary welfare standards from the start of commercial development is more effective and less costly than retrofitting welfare into established intensive systems.
