| 在小球藻的基础上分别添加鱼黏液、鸡蛋黄和鲜豆浆，以常规小球藻培育为对照组，采用3种不同强化剂培育轮虫20 d，研究不同饲料组轮虫的密度和怀卵量的差异。结果表明，不同的饵料组，轮虫密度各组间差异显著，鲜豆浆组轮虫的密度最高，达到600个/mL，其次是鸡蛋黄组，最高达到480个/mL，鱼黏液组最高为250个/mL，小球藻对照组最高为200个/mL。对照组与鱼黏液组、鲜豆浆组、鸡蛋黄组差异显著(P<0.05)。不同组轮虫怀卵量差异显著，鲜豆浆组出现两次高峰，分别为第10 d达到910个/mL，第18 d达到最高920个/mL，其次为鸡蛋黄组，也出现两次高峰，分别为第13 d达到630个/mL，第20 d达到660个/mL，鱼黏液组和小球藻对照组最高分别为400个/mL和310个/mL。研究表明，投喂鸡蛋黄和鲜豆浆对轮虫的繁殖和生长有显著促进作用，能够提高轮虫质量和营养价值。 |

| On the basis of chlorella, fish mucilage, egg yolk and fresh soybean milk were added respectively. The conventional chlorella was used as the control group. Three different fortifiers were used to grow the rotifers for 20 days. The density of rotifers and the number of eggs conceived in different feed groups were studied. The results showed that there were significant differences in rotifer density among different diet groups. The density of rotifers in fresh soybean milk group was the highest, reaching 600/mL. Followed by the egg yolk group, up to 480/mL. Fish mucus group up to 250/mL. The chlorella control group has a maximum of 200/ml. The control group was significantly different from the fish mucus group, fresh soybean milk group and egg yolk group(P<0. 05). Different groups of rotifers have significant difference in brood amount. There were two peaks in the fresh soybean milk group, reaching 910 /mL on the 10d and 920/mL on the 18th day respectively. Followed by the egg yolk group, there were also two peaks, reaching 630/mL on the 13th and 660/mL on the 20th respectively. The fish mucus group and the chlorella control group had a maximum of 400/mL and 310/mL respectively. The results showed that feeding egg yolk and fresh soybean milk could significantly promote the reproduction and growth of rotifers and improve the quality and nutritional value of rotifers. |
