for one mu of fish pond? One mu of fish pond can be stocked with 400-840 fish fry. The reason why there is such a big difference is that the yield per mu pursued is different and the way of stocking is different. If the yield per mu is 700 Jin, 400 fish fry need to be stocked, if the yield per mu is 1000 Jin, 560 fish fry need to be stocked, and if the yield per mu is 1500 Jin, 840 fish fry need to be stocked. It should be noted that the fish fry must be carefully matched.
1. Control the water temperature: First of all, control the water temperature when stocking fish fry. Fish fry is different from adult fish, and it is not resistant to low temperature, so it is usually necessary to keep the temperature between 20-25 ℃. Because it is transported, in order to avoid death after entering the pond, You need to put the bag of fish into the pond water for 20-30 minutes.
2. Pay attention to the density: Although the fry is small, the survival rate will be reduced if the fry is raised too much, and the economic benefit will be relatively low if the fry is raised too little, so we need to pay attention to the feeding density. This generally depends on the size of the fish pond and the type of fish fry. If the quality of the fish fry is good and the bait in the fish pond is sufficient, the feeding density can be larger.
3. Go to the pond when you are full: Before you put the fry into the pond, you should feed it with egg yolk. After you are full, go to the pond to improve your ability to find food. At the same time, it is also conducive to adapting to the environment. It is easy to die if you go to the pond on an empty stomach.
