N2 - In this research an experiment was executed with sole which combined the work of the projects KB Marine Resources (KB-34-2c-4) and KB Biorefinery (KB34-3a-1). The aim was to evaluate the effect of the two mussel extracts as an ingredient in a formulated diet on growth, hematocrit (Hct) and hemoglobin(Hb) levels of common sole. The experimental set-up contained six diets; fresh ragworm (the positive control), blanched mussel (the control for the extracts), a formulated diet with either extract A (the fraction’s freeze-dried pellet), B (the fraction's freeze-dried supernatant) or a combination of both and a commercial pellet (the negative control). All diets, except blanched mussel, were well eaten, and fish growth exceeded expectations. All diets increased Hb levels compared to the commercial pellet. Sole fed the diets containing 15% mussel extract A or AB showed an similar increase and sole fed the diet containing 15% of extract B even a higher increase in Hb level than sole fed blanched mussel meat. Sole fed the diets containing extracts B or AB showed higher Hb levels than those fed with extract A, suggesting that the bioactive(s) responsible for increasing Hct and Hb levels were concentrated in extract B. Moreover, both processes developed to produce the extracts and the formulated pellet diet do not noticeably affect the bioactive(s) responsible for the increase of the Hct and Hb levels in sole.
