在天津地区进行许氏平人工育苗研究，并进行了不同环境对许氏平人工育苗影响的研究。选择9个室内养殖池分为3组，分别为正常组、投放人工鱼礁组和控制光照组，每组3个养殖池，通过不同环境下的培育来研究各试验组许氏平仔稚鱼生长率、成活率的状况，同时观察人工鱼礁对许氏平的集鱼效果。试验结果表明，引进怀卵许氏平亲鱼50尾，经过人工强化培育，获得初孵仔鱼65万尾，经75 d培育，最终获得全长为3 cm稚鱼11．12万尾，成活率达17．1％；室内人工鱼礁对许氏平亲鱼的集鱼效果非常明显，对苗种的效果不明显，而且对苗种生长率和成活率的影响与正常组相比差异不大，分别为0．03～0．035 cm／d和18％～18．57％；相比之下，34～65 lx的光照度比0．2～3．0 lx的光照度更适合苗种的生长发育。

The artificial breeding of Schlegel’s rockfish Sebastes schlegeli was on the first time conducted in Tianjin ,and impacts of different environmental factors on the artificial breeding were studied .The fry were reared in 9 indoor tanks where artificial reefs were disposed ,where light was controlled or where were under normal light as a control to evaluate the effects of reef and light on the survival ,grow th and aggregation of the fish .During the experiment ,50 broodstocks were induced to spawn ,650 000 newly hatched larvae were obtained ,and 111 ,200 juveniles with total length of 3 cm were reared in 75 days with survival rate of 17 .1% .High aggregation of the fish was found in the indoor tanks where the artificial reefs were disposed .There were no significant differences in survival (18% -18 .57% ) and growth (at growth rate of 0 .037 -0.035 cm/d) in the tanks where artificial reefs were disposed compared with the normal group .Meanwhile ,better growth was observed under light intensity of about 34-65 lx than under light intensity of some 0 .2-3 .0 lx .
