| In the context of an increasing demand and a declining supply from fisheries, worldwide aquaculture production of abalone has greatly increased in the last decades. Selective breeding has been initiated to improve growth in major abalone species. In France, the abalone production was initiated 30 years ago and struggles to develop. This CIFRE PhD co-financed by France Haliotis, the only French hatchery in activity, was initiated to study early domestication process of farmed abalone population and to provide knowledge required to design a selective breeding program adapted to this company. Wild and farmed populations were compared, showing that, until 2013, farmed and wild abalone presented similar performances. However, lower physiological and behavioural... |

| The domestication of Haliotis tuberculata began recently. During this domestication process, abalone may acquire behavioural and physiological traits to become more adapted to their captive environment. These modifications could be the result of intentional selection on production traits, or of unintentional selection due to specific conditions experienced in the farm environment. In order to study this process, progenies of 3 different broodstock origins were studied. Wild abalone, farmed abalone selected for faster growth at 5% selection pressure and randomly selected farmed abalone were used as broodstock. Farmed abalone were the third generation of abalone resulting from systematic mating between wild and farmed broodstock (either males or females were... |
