“…All experiments were repeated three times. To determine the fatty acid composition, Artemia enriched in accordance with the appropriate feeding methods were analysed quantitatively using gas chromatography according to the methods of Morrison & Smith (1964) and Parrish (1987), as presented by Kwon & Park (2012). The resulting compositions of the various feeds are shown in table I.…”

“…After 3 days, three shrimp larvae from each stage were collected at each time point as three separate sample replications. After lyophilisation, their fatty acid content was analysed quantitatively according to the methods of Kwon & Park (2012). In addition, their amino acid and total protein levels were analysed using an automatic amino acid analyser (L-8800; Hitachi, Japan) and Amino Acid Standard Solution Type H (Wako, Japan).…”

This study was conducted to determine the optimum feed selection for the spiny lebbeid shrimp, Lebbeus groenlandicus, from zoea to megalopa larva. To the shrimp zoeae, untreated hatching Artemia meta-nauplii, or either of two kinds of enriched Artemia, were supplied as feed daily, in a concentration of 3 individuals/ml. Throughout the experimental trials, 17.6-18.1 days elapsed until reaching the megalopa larval stage. In the starving trials, no mortality was observed; the mortality values observed in the experimental trials, between 4.8 and 9.5% were considered low and not significantly different (P >0.05). Neither fatty nor amino acids varied significantly in the zoea I and II stages in either the feeding or starving trials. Highly unsaturated fatty acids and amino acids were significantly lower in the megalopa stage in the starving group, compared with the feeding groups (P <0.05). Therefore, feeding was proven not to have any effect in the zoea I and II larval stages. However, for the megalopa larval stage, a feed containing supplementary amino acids and fatty acids evoked a positive effect.
