Abstract

Macro- and micro-nutrients including amino acids and fatty acids are nutrients that play a very important role in the reproduction of tropical abalone broodstock. The purpose of this study was to determine macro-nutrients (proxsimate composition) and micro-nutrients including amino acid and fatty acid profiles, both essential and non-essential in tropical abalone feed and meat fed artificial diet with different protein contents. Twenty abalone broodstocks were placed in each plastic basket in a concrete tank and given artificial feed with protein content of 30% (treatment A), 35% (treatment B), 40% (treatment C) and 45% (treatment D). The feed dose is 5% per weight of biomass with the frequency of feeding twice a day at 07:00 and 19:00. Each plastic basket is equipped with a section of PVC pipe with a length of 30 cm as a shelter with a running water system and is supported by an aeration system. Parameters measured were proximate composition, amino acid profile and essential and non-essential fatty acids of abalone feed and meat. Data were analyzed descriptively. The results showed that the composition of proximate, amino acids and fatty acids of the feed was in accordance with the nutritional needs of the abalone broodstock. Furthermore, the higher the dose of protein in the artificial feed, the higher the protein, fat and total amino acids, on the contrary, the lower the total fatty acids in the abalone broodstock. Based on the results of the study, it was concluded that the best artificial feed protein dose was 45%.

Keywords: Amino acids, fatty acids, protein, proximate composition and abalone broodstock.
