People should release fish in the cool afternoon, with an average density of 150-250 fish/m2. When the fish is released into the pond, it should be nursed immediately and nursed 4-6 times/day. The food portion for 100,000 fry in the first week is as follows: cooked egg yolk 20% and soybean meal or soy milk 80%.

Farming models

Nowadays, Vinh catfish are often raised in garden ditches or rice fields or grafted in cages and even in the model of husbandry combined with fish farming. It is necessary to improve rice fields or garden ditches before stocking fish similar to raising fish in ponds. In the process of raising Vinh catfish in the field, people need to pay attention to the time of rice cultivation and the time of spraying agricultural drugs on the rice, along with the use of Chet rice to contribute to improving the productivity of Vinh catfish raised in the rice field. .

The raising of catfish in garden ditches or rice fields with low density and using natural food sources is the main thing. However, to achieve high productivity, fish need to eat more other foods. People can take advantage of locally available foods such as tapioca leaves, sweet potatoes, grass or duckweed to feed the Vinh catfish.

Besides, it is also necessary to feed the fish with cooked beans, bran, and fishmeal with an amount equal to 5% of the amount of fish stocked in the pond, the mixing ratio is as follows: 50% pureed bran + 30% cooked beans + 20% fish meal. People need to feed fish at fixed points about 15-20m apart in field ditches or garden ditches or can be arranged near 4 corners of the pond. Note with the water mode, it is best to change the water according to the tidal regime so that the water in the ponds and ditches is always clean and cool.

We need to clear the grass around the shore to limit the harmful effects of catfish: frogs, snakes, and frogs. We should pile small piles of scrub under ponds and ditches so that fish can take shelter and live on during prolonged hot weather.
