摘　　要：用人工催产和从自然海区采集的六线鱼受精卵１９．６万粒（１０９１ｇ），在水温１０～１４℃、微充气、日换水量１５０～２００倍并每日洗卵１次的条件下，孵化出仔鱼１１万尾，孵化率为５６％。鱼苗培育水温为１１．５～１６℃，在不同发育期分别使用海水小球藻、褶皱臂尾轮虫、卤虫幼体和不同规格的微型人工配合饲料进行饲喂，经４５～６０ｄ精心培育，共育成平均全长３．４９ｃｍ的六线鱼商品苗种１．８３万尾。From 1.96×10 5 inseminated greenling eggs which were induced to spawn artificially or collected from the hatchery and open sea,1.1× 10 5 larvae have been obtained with the water temperature ranging from 10℃～14℃,a little aeration, the water-changing 150～200 times as much daily and an egg-washing procedure oncs a day.The hatching rate reached 56% according to the figures mentioned above. Then the greenling larvae were reared in the fish pond in which the water temperature was kept between 11.5～16℃, and the microalgae (Chlorella), fortified rotifer(Branchionus plicotilis),artemia(Artemia salina) nauplii and various compound microfeed were separately provided to the fish larvae at different growing stage. After having been carefully reared for 45～60 d,about 18 300 greenling fingerlings were obtained with an average total length of 3.49 cm.
