3-meter-deep fish ponds? 3-meter-deep fish ponds are suitable for grass carp, big head fish, bream, crucian carp and so on. If only one kind of fish is raised, there is no need for the fish pond to be too deep, but if you want to raise it, you should ensure that the fish are layered, which requires a certain depth. For example, grass carp will move in the middle and lower layers of the water, big head fish will be in the upper layer, and bream will live in the bottom of the water. They will not interfere with each other, feed separately, and use space.
raise fish in fish ponds? 1. Clear the ponds in advance: fish in fish ponds must be cleared in advance. The purpose of pond cleaning is to sterilize and disinfect, and at the same time to eliminate possible harmful organisms. Usually, quicklime and bleaching powder are used to clear the pond, which are sprinkled on the whole pond after being mixed with water, and then fish can be raised again after one to two weeks. And
2, release that fish fry: after the pond is clear, releasing the fish fry is needed. The fry with good quality and strong physique is selected to be put in, the best time for putting in is from the last ten days of May to the middle ten days of June, and the temperature is above 18 deg C, so that the fry is easy to survive after being put in, and the growth speed is also very fast.
3. Daily management: In the daily feeding process, we should pay attention to feeding, generally regularly and quantitatively, and fertilize the water to increase the nutrition of the water, so as to cultivate some plankton, so as to provide some filter-feeding fish, so that they can eat enough.
