Compared with the conventional hydrothermal and soil-feeding methods, Astragalus verrucosa feedwater has the characteristics of rapid growth, low cost, high yield, and convenient catching. Its breeding technology has the following four points:
First, build a pool to build a place where there is a constant flow of water. The pool is best built indoors. It is made of concrete bricks. The depth of the pool is 2 to 3 meters. The wall of the pool is about 40 centimeters high. The relative position of the pool is set at 3 centimeters. 4 cm inlet holes and 2 drainage holes. The height of the water intake hole and the bottom of the pool are the same. The height of the drain hole is the same as that of the bottom of the pool, and the height of the other is 4.5 cm above the bottom of the pool. The metal mesh cover is required to prevent the escape.
2. After the stocking pool has been built, plug the total drain well, fill it with water for 5 days to 7 days, then dry the water, and then plug the bottom drain hole to keep a small amount of water in each pool. The water depth is 4 cm to 5 cm. After the worms are sterilized, they are stocked in time and put 4 kg to 5 kg per cubic meter.
Third, when feeding and feeding, they will not eat artificially fed feeds and need to be fed. The method is to feed 2 days to 3 days after stocking and feed at night. The feed can be used for clams, clams, and snails. The feed is chopped and divided into small piles on the side of the inlet. And increase the amount of water flow. The first feeding amount was 1% to 2% of the total amount of maggots, and gradually increased to 3% to 5%. After eating is normal, the silkworm mealworms, fly maggots, cooked animal viscera and blood meal, fish meal, rice bran, melon husk, etc. can be mixed in the priming feed. The first time, 1/5 can be added, and 1/5 of the quotation can be reduced. Food feed. If you eat normally, increase it by 1/5 every day. After 5 days, you should cancel the feed intake.
Fourth, management and rearing for a period of time, if the size of the cockroach fish in the same pool appears uneven, large-mouth fish should be kept in a timely manner to prevent large fish to eat fish.
