Summary The main goal of this project was to increase viability and quality of cod and halibut larvae before and during the first feeding period by using bioactive products. The aim was also to increase the exploitation and value of pollock. The findings of previous projects in halibut culture were promising and indicated that treating live feed is a suitable method to carry bioactive products to the larval intestines during first feeding but the intensities of treatment needed to be further investigated. New facilities have been developed in relation to the project for research in the live feed culture at Fiskey Ltd. to promote increased stability in the production of halibut fingerlings. Repeated experiments have been conducted in the culture of rotifers and results indicates good tolerance towards treatment with bioactive products in certain intensities. The overall results of the project indicated that pollock peptides may promote increased growth and quality of cod larvae during first feeding. The results also indicate the presence of IgM and lysozyme early post hatching, but it has not been observed in cod larvae of this size before. Furthermore, results also indicate that hydrolysates from pollock can stimulate the production of these factors in cod larvae. Treatment using pollock peptides, did not affect the bacterial community structure of live feed or cod larvae, however a similar structure was observed in larvae from the most successful production units different from other tanks. The results therefore indicate a bacterial community structure that may be preferable to the cod larvae.
