If there is no water source in the fish pond, you can dig it deep, and then wait until it rains to store water, or you can fetch water from other places. Usually, the place where the fish pond is built should be close to the natural water source, so it is more convenient to take water. Besides, groundwater can also be used. However, this method is costly, so it is better to transport water from other places. If the fish pond is large enough, it is ok to wait for rain.

1. Choose fish species: Fish pond culture should first choose the right fish species. Usually, the common fish are carp, crucian carp, grass carp, silver carp, bighead carp, etc. These fish are easy to raise, but their economic value is not very high. If you want to improve your income, you should choose some slightly unpopular economic fish.

2. Feeding density: In order to ensure that the fish can grow up smoothly, the feeding density is also crucial. Usually, the density of small fish can be higher, but as it grows up, it is necessary to gradually separate feeding, keep the same size together, and reduce the feeding density to ensure its activities.

3. Disease prevention: Fish farming should also pay attention to disease prevention. Once infectious diseases strike, it will often cause great losses. Therefore, we must pay attention to keeping the water environment clean and hygienic in peacetime, do not put food of unknown origin into fish ponds at will, and pay attention to heat preservation when changing seasons.
