Environmental control of halibut broodstock and rearing procedures for feeding larvae - FC0107

R&D Summary Objective:- Examine the effects of variations in diet and environmental conditions in rearing tanks on the spawning performance of halibut broodstocks and survival of first feeding larvae. Key customer purpose:- Provide a sound scientific basis for the consistent production of high quality eggs and larvae, leading eventually to the diversification of the fish farming industry.
1) Summarise the existing information on performance of captive halibut broodstocks in relation to holding conditions. 2) Review the current use of intensive rearing techniques for halibut larval culture. 3) Define and install broodstock environmental control systems at Ardtoe using existing tank facilities. 4) Compare the spawning performance of halibut broodstocks subjected to controlled differences in environmental conditions. Submit recommendations on broodstock holding conditions based on this work. 5) Refine the current techniques for intensive rearing of larval halibut by conducting trials to compare the suitability of different diet-types and environmental conditions.
