Catfish fry can be cultivated in cement ponds, in upper ponds or in cages. The area of the earthen pond should not be too large, generally 100 to 500 square meters. The stocking density is 500 tails per square meter. Put the same batch of seedlings in the same pool to prevent individual differences from swallowing and killing each other.
The key issue in the fry cultivation stage is the opening bait. Therefore, before the fry go to the pond, first use quicklime or bleaching powder to thoroughly clean and disinfect the pond, and then apply organic fertilizer (cow, horse manure, etc.) to fertilize the water quality, so that the zooplankton can multiply and ensure that the fry will have abundant and palatable bait after the pond. (such as rotifers, cladocerans, etc.). In the later stage, a paste feed or micro-particle bait made of fish meal and flour can be fed. Cultivated for 15 to 20 days, the body length is 3 to 5 cm, and it can be grown out of the pond into the paddy field.
