After the juveniles are raised in a sand bowl or shallow basin for 2-3 days, they can be moved to the nursery to raise them. Excessively high or low temperature is not conducive to the growth of young children. Therefore, for the early (July-August) and late (about October) hatched juveniles, do not move directly into the outdoor nursery pool for breeding. It is best to put them in the indoor pool for breeding. If the conditions cannot be maintained in the indoor pool, shade outdoor facilities shall be used to cool or keep warm. In the middle period (before and after the beginning of September), hatched juveniles can be kept directly in the outdoor nursery pool.
Juvenile breeding stocks should be stocked with 15-30 eggs per square meter of water, or 50 eggs. According to the hatched time and size of juveniles, they should be stocked separately.
Juveniles have higher requirements on bait, and the bait should be fine, fine, soft, fresh, tender, nutritious, and palatable. Usually feed the larvae, clams, chironomid larvae, silkworms, etc. within one month after hatching, and feed chickens, duck eggs, fresh fish fillets, and animal livers. Avoid feeding. Salted animal meat or internal organs, and do not feed high fat content bait. In the feeding of animal viscera, large fish, shrimp, river clams, snails and other bait, must be crushed before feeding, in order to improve palatability. If possible, it is best to mix fishmeal, egg yolk or fish and shrimp, snail, and quail meat and then add a small amount of flour to make artificial compound feed. Feeding should not only be fixed (set up food table), timing, but also quantitative. The general feeding amount is 5-10% of the total weight of the whole pool and should be increased or decreased according to appetite, weather, and water quality.
Before the juveniles are introduced into the pond, they are soaked in one-tenth of potassium permanganate solution for 1-2 hours. Juveniles have poor ability to adapt to poor water quality environment. Therefore, the bait and dirt in the pool should be removed frequently, and new water should be replaced every 3-5 days (the temperature of the new water should be close to the temperature of the original pool). For the whole pool of 20-30% water, the transparency of the water is maintained at 30-40 cm.
The most important thing in juvenile breeding management is wintering management. Because the growth time of young shells is not long after shelling, combined with the individual weight of only about 10 grams, only 3-4 grams of late shelling, and thus poor adaptability to overwintering. In order to ensure safe wintering for juveniles, feeding and management should be strengthened before the juvenile feed is stopped during the autumn to ensure that foods that are rich in nutrients and high in fat content can be accumulated in the body fat. When the outdoor temperature drops to about 10°C, all of the children should be transferred to the indoor nursery pool for winter. At the bottom of the larvae, a 20-centimeter-thick powdered sand should be added, and water should be poured 5-10 centimeters, so that the larvae entering the pool can drill into the sand for winter. The wintering stocking density of juveniles is 100-200 per square meter. It is appropriate to keep the temperature of the water at 2-6°C during winter. If you encounter cold current during the wintering process, you can warm up the furnace appropriately so as not to drastically reduce the water temperature in the pool. However, it is also not possible to raise the indoor temperature too high. Otherwise, the infant will wake up during hibernation, resulting in the death of the body with too much nutrients. During the winter, the pool water is changed every two weeks to one month to keep the water fresh.
Rice is a
finished product made after the process of rice cleaning, glutinous
rice, rice milling, and finished product finishing. The
embryo and aleurone layer of rice contain nearly 64% of rice nutrients
and more than 90% of the nutrients required by the human body. It is the
main food of the people of the South.
The carbohydrate in rice is mainly starch, and the edible rice has higher nutritional value.
Storage taboo
Rice
should not be stored at the same time as foods with high moisture such
as fish, meat, vegetables, etc., otherwise it will easily cause water to
cause mildew; rice should not be stored directly on the ground, and
should be placed on a dry, ventilated and clean pad; indoors should be
stored with high moisture content. Otherwise, it
is easy to absorb water and cause mildew; the family avoids rice stored
in the kitchen because the kitchen has high temperature and high
humidity, which has a great influence on the quality of rice.
