　　利用室外水泥池,采用全人工配合饵料投喂的方法对花鲈(Lateolabrax japonicus)进行为期274d的养殖实验,分别测定其在不同养殖盐度条件下的生长状况、成活率、特定生长率和饲料系数。结果表明,在盐度12-18时花鲈生长速度、成活率和特定生长率较高。通过回归分析得出,其生长速度的最适盐度为16-17；盐度12和18组饲料系数较低,分别为1.57和1.62,盐度30组最高；各组间在成活率方面差异不显著。因此,Ⅰ龄花鲈养殖的最适宜生长盐度理论值为16-17,在此条件下可实现较高的生长速度、特定生长率和饲料转换率。

Assessments on effect of different salinity on Lateolabrax japonicus were carried out in outdoor pond for 274 days. Fishes were then sampled to measure growth characteristic, survival rate, specific growth rate and food coeffi-cient at each salinity. The results showed that the growth rate, survival rate and specific growth rate of L. japonicus cul-tured in salinity range from 12 to 18 was higher than in other groups. Using regression analysis, the optimum growth sa-linities range of L. japonicus was 16-17. The food coefficient of L. japonicus cultured at salinity of 12 and 18 was 1.57 and 1.62, respectively, and lower than that in other groups. The highest value of food coefficient was gained while L. ja-ponicus was cultured at the salinity of 30. There was no significant difference between different salinity groups in survival rate. The results indicated growth rate, specific growth rate and food conversion rate of L. japonicus cultured at the salinity of 16-17 could be improved.
