To raise fish in rural fish ponds, it is necessary to control the depth of the pond at about 2 meters, then sprinkle quicklime at the bottom of the pond for disinfection and sterilization, and sprinkle base fertilizer in the sludge of the pond to promote the growth of aquatic plants. In addition, fish such as grass carp, silver carp and crucian carp can be mixed and fed twice a day.

How to raise fish in rural fish ponds 1, pond depth

To raise fish in rural fish ponds, it is necessary to drain or add water to make the water depth about 2 meters. In addition, it is necessary to clean up the sundries and silt at the bottom of the fish pond to keep the depth of silt around 10 cm. Then we should sprinkle quicklime into the mud for disinfection, sprinkle fertilizer into the pond to promote the growth of aquatic plants and algae and provide food for the fish.

Step 2 choose varieties

In rural fish farming, grass carp, silver carp, carp, crucian carp, bighead carp and other fish can be selected for polyculture, and the water temperature should be kept stable at 5-7 degrees to avoid fish death, and the fry should be put into potassium permanganate solution 1 min to reduce the chance of illness.

3. Feeding management

When raising fish, you need to feed the fish twice a day. You can provide them with rotifers, cladocera and chironomid larvae. You can also plant algae such as verticillata, Sophora alopecuroides and POTAMOGETON in the pond, and take out the leftover feed every night to avoid the deterioration of water quality and the death of fish.

4. Feeding methods

Fish ponds in rural areas should be inspected every night to remove the dead fish and sprinkle chemicals into the pond according to the symptoms of the fish to avoid infectious diseases. Moreover, in summer, it is necessary to build a sunshade on the fish pond to keep the water temperature constant, which is conducive to the growth and reproduction of fish.
