摘要
进行了中华乌塘鳢（Ｂｏｓｔｒｉｃｈｔｈｙｓｓｉｎｅｎｓｉｓ）人工育苗试验，采用背鳍基部肌肉注射、多次注射激素促熟催产、控制水温、不断充气等措施，提前１个多月孵出鱼苗，相对延长了养殖期，提高了经济效益。试验证明：培育亲鱼投喂活沙蚕好，雌雄比１∶１，孵化水温２６～２８℃，盐度１６～１７，注射ＬＲＨ－Ａ剂量１５０μｇ／尾，可提高催产率。
An experiment was made on artificial breeding of Bostrichthys sinensis.After some technical measures,such as periodically injecting LRH A in small dosage at the fin base muscle of the parent fish to mature earlier than in natural condition,controlling the water temperature and charging the water with air continuously,the fry were hatched out one month ahead of time.The experimental result shows:it can raise the rate of spawning,fertilization and fry emergence to feed the parent fish with clam worm,arrange the male and female parent fish in one and one,keep the hatching water temperature at 26～28℃ and the salinity at 16～17 and inject LRH A with the dosage of 150 μg per individual.
