A diet for Atlantic halibut-larvae was formulated taking into account the fact that marine-fish larvae have a limited ability to assimilate protein and lipid. Dietary protein consisted of a free amino-acid premix (7.2% of crude protein), predigested-squid mantle (7.2%), squid mantle (8.6%) and cod-muscle mince (77.0%). Lipid sources were soyabean lecithin (33% of crude lipids), crude phospholipids extracted from cod roe (10%) and sardine oil (57%). Larvae were weaned onto the experimental diet at wet-body weights of 0.07, 0.10 or 0.16 g, respectively. The experimental diet was fed for 31, 25 or 17 days, respectively, and the experiment was terminated on the same calendar day for all groups. A control group was fed with Artemia nauplii enriched with DHA Selco from 0.07 g. Survivals ranged from 78% in larvae transferred at 0.10 g to 96% in those transferred at 0.16 g and in the control group. Daily specific-growth rates (SGR) were 3.1 +/- 0.07, 3.3 +/- 0.11 and 2.2 +/- 0.01% day(-1) in larvae transferred at 0.07, 0.10 and 0.16 g, respectively, while growth in the control group was 5.1% day(-1). It was concluded that weaning of Atlantic-halibut larvae is feasible from 0.7 g (approximately 20 days post first-feeding) when the formulated diet contains predigested protein and ample amounts of phospholipids.

The supply of amino acids during early feeding stages of marine fish larvae: a review of recent findings (2003, background): “Moderate, but not high, levels of protein hydrolysates have been shown to improve growth and increase survival in young stages of different fish species (Carvalho et al., 1997; Day et al., 1997; Cahu et al., 1999; Hamre et al., 2001).”
A review of the use of copepods in marine fish larviculture (2011, background): “Past studies have shown that young marine fish larvae are able to utilize peptide chains in protein hydrolysates (Zambonine Infante et al. 1997; Cahu et al. 1999; Hamre et al. 2001), and that amino acids supplied in the diet in this form may reduce larval spine malformations (Cahu et al.”
Biochemical composition of copepods for evaluation of feed quality in production of juvenile marine fish (2008, background): “Concordantly, recent studies have shown that young marine fish larvae also are able to utilize peptide chains in protein hydrolysates (Zambonino Infante et al., 1997; Cahu et al., 1999; Hamre et al., 2001), and that amino acids supplied in the diet in this form may reduce larval spinal malformations”
