摘要:
本研究通过设置5种不同背景色(白色、红色、绿色、蓝色、黑色),以探究背景色差异对红螯螯虾(Cherax quadricarinatus)生长、存活、体色及栖息行为的影响。结果表明养殖56 d后黑色背景色组红螯螯虾体重增长量、特定生长率和成活率最高,分别为32.66 g、1.74%和76.4%,其次为绿色、蓝色和红色背景色组,白色组最差(P<0.05);黑色和红色背景色红螯螯虾饵料系数最小(3.73~3.80);黑色背景色条件下红螯螯虾体色偏蓝,ImageJ分析表明,黑色背景色组虾壳RGB值中R和G值显著低于其他各组,黑色背景色虾壳虾青素含20.23 mg/kg,亦显著低于其他各组(69.34~82.15 mg/kg)(P<0.05);黑色背景色条件下红螯螯虾分布于遮蔽物外的几率显著高于其他各组(P<0.05)。综上所述,背景色能够影响红螯螯虾生长存活、体色及行为分布,养殖中采用黑色作为背景色能够显著提高红螯螯虾生长存活,改善虾体颜色。

Abstract:
In this study, five different background colors (white, red, green, blue, and black) were set to culture Cherax quadricarinatus, in order to investigate the effects of background color on the growth, survival, body color, and distribution behavior of C. quadricarinatus. After a 56-day rearing period, the black-background C. quadricarinatus showed the highest increase in the body weight, specific growth rate, and survival rate (32.66 g, 1.74%, and 76.4%, respectively), followed by the green-, blue-, and red-background groups, with the white-background group showing the lowest values (P<0.05). The feed coefficients of the black- and red-background C. quadricarinatus were the lowest (3.73–3.80). The body color of C. quadricarinatus reared in black condition was bluer than those of other groups. ImageJ analysis showed that the R and G values of the black-background group were significantly lower than those of other groups, and the astaxanthin content in the black-background group was 20.23 mg/kg, which was significantly lower than those of other groups (69.34–82.15 mg/kg) (P<0.05). Moreover, the probability of C. quadricarinatus distribution outside the shelter was significantly higher in the black-background group compared with the other groups (P<0.05). In summary, the background color can significantly affect the growth, survival, body color, and behavior distribution of C. quadricarinatus. Using a black background in C. quadricarinatus rearing can improve their growth and survival rate, as well as body color.
