摘　　要：报道了室内养殖牙鲆的试验结果，１９９２年～１９９５年进行的小规模试验，将受精卵培育至鱼苗、成鱼直至成熟亲鱼。在水温为２℃～２５℃范围内，经过３６个月将全长为５３ｃｍ鱼苗培育至全长为４６８ｃｍ、体重为１７８０ｇ的商品鱼，成活率为５０６％。１９９７年～１９９８年进行的生产性养殖试验，在水温为１０℃～３３℃范围内，经过１０个月将全长为５４ｃｍ鱼苗养至全长为３３４ｃｍ、体重为３５６ｇ的商品鱼，成活率为６７％。另外，在水温为１５℃～２５℃范围内，全长为１０ｃｍ～１５ｃｍ鱼苗和２０ｃｍ～２５ｃｍ鱼苗的适宜培育密度分别为１５０尾／ｍ２～２００尾／ｍ２和５０尾／ｍ２～７５尾／ｍ２。This paper reports some results of a series of indoor flounder culture experiments.Smaller scale experiments were done during 19921995,involved the production from fertilized eggs,fry,juvenile,to broodfish.Among 225 of water temperature.28 months were needed from the fry 53cm in total length(TL)to commercial size(394cm TL)and 927g bodyweight(BW),506% of survival rate(SR)was achieved.Larger scale experiments were done between 19971998In the conditions of 1030 of water temperature,18 months were costed from the fry(54cm TL)to the commercial fish(334cm TL,356g BW),67% of SR was obtained.Besides,it was found that when water temperature were in the range of 1525,the suitable culture density were 150200 and 5075 individuals/m2 for smaller juveniles(10cm15cm TL)and larger juveniles(20cm25cm TL)respectively.
