Culture technology of rice flower fish

In fact, rice flower fish is not a species of fish, but the use of rice fields raised out of carp, grass carp and other fish. Rice cauliflower fish can feed on weeds and pests in rice fields, and the excreta produced by fish can be used as fertilizer for rice. Therefore, rice cauliflower fish is a kind of pollution-free green food, and the breeding cost is also very low. So how to raise rice flower fish? The following editor brings you the culture technology of rice flower fish, let's have a look!

1. Selection and stocking of seedlings

The sowing time of rice in the south is usually from March to April, and then transplanting is carried out at the end of April. When we release fish fry, we should pay attention to it about a month after transplanting, so the release time of fish fry should be around the end of May. In the selection of fish fry, we should pay attention to the quality of fish fry, do not choose inferior fish fry, to avoid the survival rate leading to culture failure. Then we should pay attention to control the number of stocking, because it is a symbiosis of rice and fish, so the number of fry should not be too much, generally should be controlled at about 300. Finally, there is the water level, the control of the water level is very critical, not only to ensure that the fish can swim freely, but also to prevent the water level from exceeding the range of seedling growth.

2. Reasonable feeding

When raising rice flower fish, we should pay attention to abandoning the feeding method of pond fish culture, because not only to meet the nutritional needs of fish, but also to prevent the impact on the growth of rice. Usually, the bait of rice flower fish is mainly biogas residue and green organic matter. Many farmers feel that the greater the fertility of the water quality, the better. Directly pour the immature farm manure into the field, thinking that it can not only promote the growth of fish, but also provide growth nutrition for rice. In fact, this will not only affect the growth of fish, immature fertilizer will also burn rice, resulting in a decline in rice production.

3. Insecticide use

Rice will be damaged by many diseases in the process of growth, so it is very important to spray insecticides. But because of raising fish, we also need to control the insecticidal and sterilizing time of rice, if the fish eat weeds and pests with pesticides and grow in such water quality. Then the mortality rate is so high that it basically loses its edible value even if it is not dead. Therefore, we should do a good job of spraying herbicides and apply appropriate amount of chemical fertilizer a week before releasing fish fry. If the occurrence of insect pests is serious, then we should also pay attention to the use of pesticides, do not use pesticides that contain highly toxic.

4. Daily management

As I just said, the management of water level is very important. when we breed, we can dig a puddle in the low-lying area of the rice field. When the water level of the rice field drops or there is less water, the fish can swim into the puddle to prevent the sun from being exposed to the sun and replenish water. Then it is necessary to do a good job of feeding bait, although fish can feed on weeds and other substances in rice fields. But if you want to ensure the healthy growth of fish, then it is far from enough. Therefore, some fish bait should be put in regularly. Then the growth of the fish should be observed regularly every day to prevent some abnormal conditions so as to facilitate the actual treatment.

The above is a brief introduction of rice flower fish culture technology. Compared with pond culture, the culture of rice cauliflower is more troublesome. But the cost is relatively low, so the benefit will increase. That's all for today's introduction. This article is for reference only. I hope it can help you all.
