| 摘要: | 为研究鱼油添加量对观赏性红鲫鱼生长和体色的影响, 在喂养红鲫鱼的饲料中分别添加质量分数0%、2.5%、5%、10%的鱼油, 投喂49d, 并将其与空白组分别进行对照. 结果表明: 添加2.5%的鱼油喂养红鲫鱼对红鲫鱼的生长最佳. 随着鱼油喂养量的不断增加, 红鲫鱼体重和体长的增加率呈一定的下降趋势. 以观赏鱼的红度、白度、黄度作为重要的评判标准, 5%鱼油添加量更有助于提高红鲫鱼的红度值, 降低白度值和黄度值. |
| Abstract: | In order to investigate the impact of fish oil on growth and body color of Carassius auratus red variety, the diet of Carassius auratus red variety is added with fish oil of different concentration level (0%, 2.5%, 5%, 10%) and fed for 49 days. The results show that 2.5% additional fish oil is the best diet for the growth of Carassius auratus red variety. The more the fish oil feeding is given, the more slowly the weight and length of Carassius auratus red variety increase. Body color is an important factor for ornamental fish, which is standardized with the degree of red, white, yellow. It is found that 5% fish oil helps increase the red color index of Carassius auratus red variety, while reduce that of white and yellow. |
