摘要

60条鳞鲤鱼鲤鱼和60条镜鲤鱼鲤鱼鲤鱼在玻璃纤维和混凝土罐中饲养。鱼的照片是用放在灯箱里的数码相机拍摄的。图像分析用于确定长度-权重和视图-区域-权重的关系。将长度-重量数据拟合为幂方程：（重量W）=a（长度L）B。R2在0.838到0.959之间。根据B值，玻璃纤维池中饲养的有鳞和镜像鲤鱼显示出负的异速生长，而混凝土池中的鱼则是正的。对于视野面积（V）-权重关系，除了幂方程外，还使用了线性（W=A+BV）和二阶多项式方程。这些方程的R2值在0.916到0.995之间。通过图像分析测量皮肤颜色。在混凝土池中饲养的有鳞鲤鱼和镜鲤鱼的L*、a*和b*值均显著高于在玻璃纤维池中养殖的鲤鱼（P<.05）。此外，在相同的视野区域内，在玻璃纤维槽中饲养的鱼往往比在混凝土槽中养殖的鱼重轻。

Image Analysis to Determine Length-Weight and Area-Weight Relationships, and Color Differences in Scaled Carp and Mirror Carp Grown in Fiberglass and Concrete Tanks

Sixty scaled carp Cyprinus carpio and sixty mirror carp Cyprinus carpio carpio were raised in fiberglass and concrete tanks. Fish pictures were taken by a digital camera in a lightbox. Image analysis was used to determine length-weight and view area-weight relationships. Length-weight data were fitted to a power equation: (Weight W) = A (Length L)B. R2 ranged from 0.838 to 0.959. Based on the B values, scaled and mirror carps reared in the fiberglass tank showed a negative allometric growth while this was positive for the fish in the concrete tank. For the view area (V)-weight relationship, linear (W = A + BV), and second order polynomial equations were used in addition to the power equation. The R2 values for these equations ranged from 0.916 to 0.995. Skin color was measured by image analysis. Both scaled and mirror carp reared in concrete tanks had L*, a* and b* values significantly higher than those reared in fiberglass tanks (P < .05). Also, the fish reared in fiberglass tanks tended to have less weight for the same view area, compared to those reared in concrete tanks.

期刊介绍： Turkish Journal of Fisheries and Aquatic Sciences" (TrJFAS) is a refereed academic journal has been published by Central Fisheries Research Institute of Turkey and Japan International Cooperation Agency (JICA), and published in English. It aims to address research and needs of all working and studying within the many varied areas of fisheries and aquatic sciences. The Journal publishes English language original research papers, critical review articles, short communications and technical notes on applied or scientific research relevant to freshwater, brackish and marine environments. TrJFAS was published biannually (April & November) between 2001 and 2009. A great number of manuscripts have been submitted to the journal for review from acceptance of the SCI index. Thereby, the journal has been published quarterly (March, June, September and December) from 2010 to 2017. The journal will be published monthly in 2018.
