Heluo meat is rich in nutrients and easy to raise, so it can be used as a bait species for pond culture.
The river clams are fertilized in vitro and the eggs develop into platter larvae. After completing the planktonic life stage, they begin to grow shells, sink to the bottom of the pool, and bury the shells in the silt in the bottom of the pool. They only stretch the straw into the water for breathing. Food. The ponds that raise river rafts cannot inject pesticides and fertilizer water, which is the most likely to cause the death of river rafts. Water quality should not be too fertile. The bottom of the pool is preferably sand. Water depth is about 1 meter. Each acre can be stocked with 60 to 130 kilograms. Hemorrhoids cannot reproduce continuously in ponds. Therefore, seedlings can be appropriately reduced in the second year. The size of the river raft seedlings is 800-4000/kg. If you purchase quail species from outside, you can transport them into sacks or turfgrass. To reduce the deaths on the way, you should maintain a certain degree of humidity, and do not stack too much. Before stocking, the pool should be drained and exposed to sunlight for 2 to 3 weeks before refilling. When growing in ponds, soy flour, wheat bran or rice bran should be fed, as well as chicken manure or other farm manure. The growth rate of the river raft is determined according to the feeding conditions. The average weight of the seed is about 0.11 g. It can be increased 4 times for one and a half months and reach 0.45 g. It can reach 0.91 g in 3 months and 2.25 g in 4 to 4.5 months. From May to June, up to 4 grams, 7 to 7.5 months, up to 5.4 grams, 50 times the weight of the original seed, then you can capture.
From the time of catching the river raft, a shovel with a net can be used. After catching it, the size is divided by iron, and the smaller individual is still put back into the original pond for feeding. ?
The river raft can also be polycultured with clams, clams and grass carp, but it cannot be mixed with herring and trout. ??
The crushed river bream is a good bait for the yellow pheasant and the pheasant can be fed directly.
