2005年网箱培育长吻鮠冬片鱼种,应用5 m×5 m×3.5 m的网箱,放养规格为3~4 cm/尾的长吻鮠夏花鱼种,放养密度56~790尾/m2,投喂粗蛋白为42%~46%的配合饲料,经7个月养殖,长吻鮠鱼种平均规格达165g/尾,成活率82.5%,单产9 kg/m2,饲料系数1.26,投入产出比1∶2.04;2006年网箱养殖长吻鮠商品鱼,应用5 m×5 m×4.5 m的网箱,放养规格为133 g/尾左右的长吻鮠冬片鱼种,放养密度32~50尾/m2,投喂粗蛋白为42%~43%的配合饲料,经6个半月时间的养殖期,养成个体规格在0.5kg/尾以上的长吻鮠商品鱼比例达86%以上,成活率82.6%~87.0%,饲料系数1.38,单产22.83~26.24 kg/m2,投入产出比1∶1.59。 In 2005, the cages were used to cultivate the species of winter mullet, and the size of 5 ~ 5m × 3.5m cages and the stocking size of 3 ~ 4 cm / / m2, fed with 42% ~ 46% crude protein feed, after 7 months of breeding, the average size of longan catfish reached 165g / tail, the survival rate of 82.5%, yield 9kg / m2, feed coefficient 1.26, Input to output ratio of 1: 2.04; In 2006, the cages were cultured in the commercial catfish with the length of 5 m × 5 m × 4.5 m. The density of 32 ~ 50 tail / m2, feeding crude protein 42% ~ 43% of the compound feed, after six and a half months of the breeding period, to develop individual specifications at 0.5kg / tail above the proportion of fish of long kiss 鮠 up to 86 The survival rate of 82.6% ~ 87.0%, feed coefficient of 1.38, yield of 22.83 ~ 26.24 kg / m2, input-output ratio of 1: 1.59.
