a fish pond 1. Location selection: To build a fish pond, first of all, choose the right location. It is usually built near rivers or lakes, so as to ensure adequate water supply, and the water quality must be pollution-free, so that the fish will be healthy, the nearby transportation should be convenient, and the long-term power supply should be guaranteed.
2. Water quality of the water source: As the water consumption of the pond is large, the use of tap water is not obvious. On the one hand, the cost is high, and on the other hand, it is necessary to remove chlorine. Therefore, river water or reservoir water should be used as the water source, and new water should be added regularly to prevent the deterioration of the water quality and to eliminate the lack of oxygen, which is also conducive to the reproduction of plankton.
3. Area and water depth: There should not be only one pond. Fish fry and fingerling need a pond of 3-5 mu, and the water depth is between 1-1.5 meters, so that fish can be raised. The area of adult fish should be at least 8-10 mu, and the depth of the pond should be 2-3 meters, so as to make the fish grow better and avoid the situation of mutual backlog.
the fish pond? Generally, the fish pond should be made into a rectangle long from east to west and wide from north to south. The ratio of length to width is about 5:3. The advantage of this is that the shade is small and the illumination time is longer, which is conducive to the photosynthesis of aquatic plants, and also convenient for management and netting. The bottom of the pond should be shaped like a turtle's back, inclined to the outlet, which is conducive to drainage and fishing. The surrounding area should be open, and forage grass can be planted, but trees can not be planted.
