摘  要：
为积累拉氏成鱼养殖技术资料,于2013年在辽宁省铁岭县范家屯水库渔场面积为0.53hm2的池塘进行了拉氏主养试验。4月20日放养7.6万尾平均体质量11.2g的拉氏苗种,搭配500尾鲢鱼(平均体质量100g),750尾鳙鱼(平均体质量150g),投喂鲤鱼颗粒饲料,池中配备3.0kW增氧机1台;饲养结果表明,经161d饲养,出塘拉氏商品鱼3350.1kg(平均体质量46.4g),成活率达95%,鲢鱼490kg(平均体质量980g),鳙鱼1050kg(平均体质量1400g),吃食鱼饲料系数为2.1;养殖期间,体质量(m)和全长(L)生长方程分别为:m=-0.0012t2+0.4286 t+10.574(r2=0.6684)、L=0.0006 t2-0.0169 t+11.343(r2=0.6623);体质量与全长的相关方程为m=0.0033L3.4673(r2=0.9117)。

摘  要：
A fat minnow Phoxinus lagowskii culture trail was carried out in a 0.53hm2 pond in a fish farm in Tieling City,Liaoning province,in 2013.Fat minnow juveniles with initial body weight of 11.2g was reared at a rate of 143 thousands individuals per hm2,aerating by apower of a 3.0kW aerator and by feeding formulated feed for common carp(Cyprinus carpio)and polycultured with silver carp Hypophthalmichthys molitrix with initial body weight of 100 g at a rate of 943 individuals per hm2 and bighead carp Aristichthys nobilis with initial body weight of 150 g at a rate of 1415 individuals per hm2 for 161 d.Total yield was harvested,including 3350 kg of fat minnow with body weight of 46.4g,a survival rate of 95%,and food conversion ratio of 2.1,490 kg of silver carp with body weight of 980 g and 1050 kg of bighead carp with body weight of 1400 g.The appropriate equation was expressed for body weight(m)as m=-0.0012t2+ 0.4286 t+10.574(r2= 0.6684)and for total length(L)as L = 0.0006 t2-0.0169 t +11.343(r2= 0.6623).The relationship between total length and body weight was described as m =0.0033L3.4673(r2=0.9117).
