Abstract
Farming, and thus the domestication of Haliotis tuberculata, began recently. We compared the responses of unselected farmed and wild abalone to stressors that occur on farms. The aim was to determine if the farm environment had induced differences in the behavioural or physiological performances of the abalone. Thirty hatchery-born 3.5 year-old abalone and thirty wild ones were reared under standard farm conditions for 6 months and characterised for 19 traits related to growth, survival, behaviour and immunology. Behavioural and immunological responses to stressors differed between the two stocks. Farmed abalone retracted and swivelled less in reaction to a finger contact. Phagocytosis effic..
