实验将加州鲈(Micropterus salmoides)鱼苗用膨化浮性饲料养成商品鱼,对膨化浮性饲料养殖加州鲈生产效果进行了分析.结果显示:在114 d鱼种养殖期内,加州鲈从5 g长至112 g,比预定的出塘规格(100 g)高出12%,饵料系数为1.14,表明鱼种阶段,加州鲈对膨化饲料有良好的反应.在159 d商品鱼养殖期内,加州鲈从155 g长至354 g,生长缓慢,平均饵料系数为1.43.
實驗將加州鱸(Micropterus salmoides)魚苗用膨化浮性飼料養成商品魚,對膨化浮性飼料養殖加州鱸生產效果進行瞭分析.結果顯示:在114 d魚種養殖期內,加州鱸從5 g長至112 g,比預定的齣塘規格(100 g)高齣12%,餌料繫數為1.14,錶明魚種階段,加州鱸對膨化飼料有良好的反應.在159 d商品魚養殖期內,加州鱸從155 g長至354 g,生長緩慢,平均餌料繫數為1.43.

The production performance of largemouth bass from fry to growout with the extruded floating feed technology was evaluated by two-year research.The research results indicated that the largemouth bass grew from 5 g to 112 g in 114 days with an average FCR of 1.14.The harvest size was 12% larger than the expected size of 100 g.The largemouth bass grew from 155 g to 354 g in 159 days with an average FCR of 1.43 at the second year,the growth was relatively slow.
