摘要
利用人工培育的亲鱼所获得的受精卵 ,孵化出仔鱼 30 0万尾 ,在水温 18～ 2 0℃、微充气的培育条件下 ,使用海水小球藻、轮虫、卤虫无节幼体和不同规格的微颗粒配合饲料进行饲喂 ,经 58d培育出平均全长 2 .3cm的苗种 132万尾 ,育苗成活率高达 64.1% ,单位水体最高出苗量达 1.33万尾 / m3;另外 ,还有 1.3～ 1.9cm的苗种
Using fertilized eggs from parent fish cultivated artificially, 3 000 000 larval fish were hatched. At the cultivation condition of temperature 18～20℃ and tiny airing, 1 320 000 seeds of average total length 2.3cm were cultivated for 58 days, reared by microalage ( Chrorella ), fortified rotifer ( Branchionus plicotilis ), nauplii of artemia ( Artemia salina ), and compound microfeed of many different sizes. The survival rate of fry was as high as 64.1%, and the maximum quantity of seed reached 13 300/m 3. Besides, there were 680 000 seeds of 1.3～1.9cm.
