进行了唇夏花培育、1龄秋片苗种培育和2龄秋片苗种培育生产性试验。夏花培育池0.67hm2,轮虫高峰期下塘唇水花鱼苗10万尾。经24d培育,鱼苗的平均全长达34.92mm,增长4.04倍,平均体质量达0.285g,增长142.5倍,鱼苗在22日龄后体质量增长较快,出塘唇夏花8.2万尾,成活率82%。1龄秋片苗种培育试验池塘面积0.27hm2,放养夏花8万尾(平均全长2.58cm),经142d培育,平均全长达16.62cm,增长6.44倍,平均体质量达37.88g,增长291.38倍,出塘秋片鱼种6.248万尾,成活率78.1%,饵料系数2.5。2龄苗种培育池塘0.2hm2,放养1万尾(平均体质量15.6g),经101d饲养,平均全长达18.21cm,增长1.56倍,平均体质量达56.66g,增长3.63倍,出塘唇鱼种9960尾,成活率99.6%,饵料系数2.2。
The experiment of cultivating Lip glans summer flower, cultivating the autumn seedling of the first instar and cultivating the autumn seedling of the second instar were carried out. Summer flower cultivation pool 0.67hm2, rotifers under the ponds ponds Suaeda Huapiao 100,000. After 24 days of cultivation, the average length of fry was 34.92mm, an increase of 4.04 times, with an average body weight of 0.285g, an increase of 142.5 times. The body weight of fry grew rapidly after 22 days of age, Survival rate of 82%. The first instar autumn seedling cultivation test pond area 0.27hm2, stocking summer flowers 80 000 (average length 2.58cm), after 142d incubation, the average full length of 16.62cm, an increase of 6.44 times the average body weight of 37.88g, an increase 291.38 folds, the number of pond fish in Autumn was 6248. The survival rate was 78.1%, and the feed coefficient was 2.5 h. The seedling culture pond 0.2 hm2, stocking 10 000 (average body weight 15.6 g), after 101 d breeding, the average length Reaching 18.21cm, an increase of 1.56 times. The average body weight reached 56.66g, an increase of 3.63 times. There were 9,960 tilapia species with a survival rate of 99.6% and bait coefficient of 2.2.
