摘  要：
为了解工厂化养殖条件下圆斑星鲽(Verasper variegates)幼鱼的生长特性,在水温9.0~22.5℃时,对圆斑星鲽幼鱼的体长和体质量进行了近1年的测定分析。结果显示:平均体长为(9.29±0.16)cm、平均体质量为(22.11±1.03)g的5月龄左右的圆斑星鲽幼鱼,经1年的人工饲养后平均体长为(36.15±0.36)cm、平均体质量为(647.97±12.54)g,体长与日龄之间呈线性关系L=1.492x+2.350,R2=0.966,其体长平均瞬时增长率为0.12,体长平均月增长量为2.44 cm;体质量与日龄之间呈指数关系Wgc=9.380 e0.264x,R2=0.960,其体质量平均瞬时增长率为0.31,体质量平均月增长量为56.92 g;体长与体质量的回归曲线Wwl=0.030x2.971,R2=0967,幂指数约等于3,表明体质量与体长的立方呈正相关系,为等比生长类型。在工厂化养殖条件下,圆斑星鲽幼鱼的体质量增长量、体质量相对生长率、体质量瞬时生长率与水温变化大体一致,16~18℃时增重较快;反映幼鱼生长阶段的生长指标、生长系数波动较大,没有显示出规律性;体质量与体长呈显著相关,处于负异速生长阶段。

摘  要：
In order to understand the growth characteristics ofVaraspervariegates under industrial farmingconditions,an one-year experiment was conducted on juvenileVarasper variegateswith the water temperaturebeing 9 ~ 22.5 ℃,and the body weight and length were measured and analyzed.The results showed that afterone year artificial rearing,the mean body weight and mean body length of the 5-month-old juveniles increasedfrom(22.11±1.03)g and(9.29±0.16)cm to(647.97±12.54)g and(36.15±0.36)cm,respectively.There wasa linear relationship between the total length and month age:L= 1.492x+2.35,R~2= 0.966,with the body lengthincreasing by 2.44 cm averagely per month and an instantaneous length growing ratio of 0.12. There was apower function relationship between body weight and month age:W_(gc)= 9.380e0.264 x,R~2= 0.960,with the bodyweight increasing by 56.92 g averagely per month and an instantaneous weight growing rate of 0.31.The length-weight relationship was W_(wl)= 0.030x2.971,R~2= 0.967,the power was close to 3,showing that body weight waspositively related to the cube of body length and the juvenile fish was of isometric growth. Under industrialfarming conditions, the body weight gain, relative weight growth rate, instantaneous weight growing rate ofjuvenileVerasper variegatuswere in line with the changing of water temperature,and the weight of juvenile fishgrew more rapidly at the water temperature of 16~18℃;while the growth indices and growth constant reflectinggrowth stage of juvenile fish,showed no regularity,and the body weight was significantly negative related tobody length,showing the juvenileVerasper variegatuswere at allometric growth stage.
