Abstract

A multi-disciplinary study will address recognised problems in halibut rearing and current gaps in knowledge. Fecundity and gamete viability will be measured in response to maintaining stock in recycled water. Puberty, oogenesis and the pattern of oocyte recruitment to be investigated using histological methods. GnRH-A implants will be provided to broodstock; effect on fecundity and gamete viability quantified. Optimum dietary ratio of the essential fatty acids 22:6(n-3); 20:5(n-3); 20:4(n-6) will be sought for halibut larvae, in order to achieve correct metamorphosis. Biology of the capsalid monogenean parasite, Entobdella hippoglossi will be studied, emphasising host selection criteria. The halibut immune system will be investigated, including maternal transfer of defences, ontogeny of immuno-competence and nature of immune response (cellular/humoral).
