Analysis and Valuation of Nutrient Components in the Muscle of Cultured Sinibotia reevesae Parent Fish
摘要
Abstract
Sinibotia reevesae is a fish endemic only to the upper Yangtze River.The nutritional quality of cultured S.reevesae was evaluated by analyzing the muscle tissue of thirty individuals of average body length, (92.27±7.70) mm, and body weight, (12.56±3.59) g.The results provide a reference for nutritional content and for protecting and culturing S.reevesae.The muscle of cultured S.reevesae was composed of water (75.24±2.25) ％, protein (19.32±0.33) ％and fat (6.60±0.59) ％.The protein includes 18 amino acids and accounting for (76.42±0.62) ％ of the muscle dry weight, higher than the standard set by the Food and Agriculture Organization (FAO).The weight ratio of essential amino acids to total amino acids (WEAA/WTAA) was 39.96％ and the ratio of essential to nonessential amino acids (WEAA/WNEAA) was66.55％.The concentrations of aspartic acid (Asp) and glutamic acid (Glu), the"delicious amino acids", were highest and the essential amino acids index (EAAI) was 63.94.Twenty different fatty acids were found in the muscle, including 7 saturated fatty acids (SFA), 6 monounsaturated fatty acids (MUFA) and7 polyunsaturated fatty acids (PUFA).Among the unsaturated fatty acids (UFA), the concentration of C18:1ω9 cwas highest.The concentration of PUFAs were low, with EPA and DHA together accounting for (3.54±0.04) ％ of the dry weight.To summarize, the muscle of cultured S.reevesae parent fish is a delicious, high quality protein food with high nutritional value.However, it is necessary to scientifically manage the EPA and DHA content of feed during artificial breeding to ensure normal reproduction of S.reevesae and the healthy development of offspring.关键词
