Optimum dietary protein and amino acid levels for the growth of juvenile sea cucumber Apostichopus japonicus
摘要
Abstract
Feeding trials were conducted to investigate the effect of dietary protein and a- mino acid level on the growth of juvenile sea cucumber Apostichopus japonicus at 4. 5~4. 8 g. The experiments on juvenile sea cucumbers were conducted over 70 days using an artificial feed, mainly composed of fish meal, Sargassum thumbergii and lees (by-products from wine and beer production). The content of protein in artificial feed was 14. 7%, 17. 7%, 19. 1% and 21. 5% respectively. The results showed that the weight gain and feed digestibility increased with the protein content in the diet. The optimum protein content was 21. 5% , resulting in the highest weight gain and feed digestibility. Based on a second growth experiment over a 40-day period, during which five different feed formulas were tested, it was found that the weight gain was maximal when the diet was rich in the following amino acids: lysine, arginine, glycine and me-thionine. It suggested that lysine, arginine, glycine and methionine are important amino acids for the growth of sea cucumbers.关键词
