原始语种摘要: Abstract(#br)A feeding trial was conducted to determine the dietary methionine requirement of juvenile large yellow croaker (initial body weight 1.23±0.02 g). The basal diet contained 43% crude protein from fish meal, soybean meal, yeast, wheat meal and crystalline amino acids with 0.65% methionine and 0.29% cystine on a dry diet basis. Six diets were formulated with six graded levels of methionine (0.66% to 1.89% in about 0.25% increment). Each diet was randomly assigned to triplicate groups of 180 juvenile fish in seawater floating net cages (1.0×1.0×1.5 m). Fish were fed twice daily (05:00 and 17:30) to apparent satiation for 10 weeks. The water temperature fluctuated from...
