英文摘要: Abstract(#br)Diet at start feeding can affect fish development, pigmentation and growth, and live feed can provide all the dietary requirements of larvae. Enriched rotifers and Artemia are normally used as live feed in the first stages of commercial larval production, however, wild zooplankton or copepods provide better results. The goal of this study was to evaluate whether supplementing enriched rotifers and Artemia (RA) with fish protein hydrolysate (RA-PH) or a small amount of wild zooplankton (RA-Zoo; 5–10% of total prey items) would improve the nutritional quality of larval cod ( Gadus morhua ), and how it correlated with larval growth rates. Wild zooplankton had significantly higher proportions of the polyunsaturated fatty acids 22:6ω3 (DHA, 23%) and 20:5ω3 (EPA, 11%). Larvae fed...
