1. Why does the water in the fish pond not dry The reason why the water in the fish pond does not dry is that the amount of water is very large, and sunlight is not easy to shine through the water surface to the bottom, so the temperature of the bottom is relatively low, and the overall heating rate is very slow. The water temperature is usually lower than the air temperature, so the evaporation rate is much lower, so the water will not be easily dried. If other water sources are connected and water comes in regularly, the pond will not dry.
2. How to raise fish in fish ponds1. Clear ponds in advance: The first thing to do in fish ponds is to clear ponds. The purpose of clearing ponds is to sterilize and disinfect, and at the same time eliminate possible enemy organisms. Usually, the drugs used for clearing ponds are quicklime, bleaching powder, etc., which are sprinkled in the whole pond after being mixed with water, and fish can be raised again after waiting for one to two weeks.
2. Put in fry: After clearing the pond, you can start putting in fry. Generally, fry with good quality and strong physique should be selected for delivery. The delivery time is from late May to mid-June, and the temperature should reach above 18 ℃, so that it is easier to survive and grow quickly after delivery.
3. Daily management: In the daily feeding process, feeding should be done regularly and quantitatively. If fry are raised, fertilization should be carried to the water to increase the nutrition of the water, so that some plankton can be cultivated, and some filter-feeding fish can be provided with food so that they can eat enough.
