摘　　要：利用海水土池或网箱养殖3龄以上的红鳍笛鲷成鱼,于催产前二个月进行强化培育.在水温达到18～24℃时,用HCG和LRH-A2或LRH-A3进行催产,混合或单一使用,剂量视亲鱼成熟度而定.受精卵在盐度28～30.2,水温18～22℃,pH值8.2的环境中经15～16h孵化.开口仔鱼在土池水温26.5～30.2℃,盐度18～24,pH值7.8～8.8的条件下,经26～30d培育,完成变态发育进入幼鱼期.Lutjanus erychopterus （Blooh） being cultivated in seawater pond or floating net -cage were sdected as broodstook. 3months before being inducing, broodstock were raised intensively. At the seawater temperature of 18 - 24℃, broodstook were induced by HCG and LRH -A3. The hormone usage depends on maturity of broodstock. The fertilizing eggs hatching took 15 - 16h, at the hatching condition of water salinity 28 -30, temperture 18 -22 ℃, pHS. 2. It took 26 -30days for larvae to metamorphose into youngfish.
