摘要
于2022年12月—2023年3—7月,对象山港网箱养殖的8月龄及11~15月龄小黄鱼(Larimichthys polyactis)的生长特性进行分析。结果表明,雌和雄个体质量与体长的最佳拟合曲线均为幂函数,且雌和雄鱼生长差异不显著(P>0.05)。体长与体高、体宽、头长、吻长、尾柄长、尾柄高的最佳拟合曲线为线性方程。体质量与体长的最佳拟合曲线为幂函数,其中幂函数指数>3,说明网箱养殖小黄鱼为异速生长。基本生长指标及相对增长率均随月龄增加呈上升趋势,肥满度与肝体比随水温升高呈先下降后上升趋势,性腺指数随水温升高呈先上升后下降趋势。
The growth and morphological parameters of Larimichthys polyactis(8 and 11~15 months old)cultured in cages in Xiangshan Bay were observed and analyzed in December of 2022 and March to July of 2023.The results showed that the best fitting curves of body weight and body length of male and female individuals were power functions,and there was no significant difference in growth between male and female fish(P>0.05).The best fitting curves of body length and body height,body width,head length,snout length,caudal peduncle length,caudal peduncle heightwere linear equations.The best fitting curve of body weight and body length was a power function,and the power function index is greater than 3,which indicated that the cage culture of Larimichthys polyactis was allometric.The basic growth index and relative growth rate showed an increasing trend with the increase of age,the condition factor and hepatosomatic index ratio first decreased and then increased with the increase of water temperature,and the gonadal index first increased and then decreased with the increase of water temperature.
