Misgurnus anguillicaudatus is a small omnivorous fish with a wide range of feed sources. Daphnia, earthworm, fly maggot, etc. It is a natural food organism of loach, which can be fed with rice bran, bean cake, bean dregs, blood powder, wheat bran and so on. Under the condition of artificial reproduction. The food intake of loach is closely related to the water temperature. The daily feeding amount is 1% of the total weight of loach in March, 4% in April-June, 1% in July-August and 4%- 10% in September.
The feeding method is to build a feeding platform in the loach pond and put the feed on the feeding platform. Feed should be fresh, pollution-free, non-rotting and non-deteriorating. The feeding time is usually around 9: 00 am, and the feeding amount is subject to the loach eating within 3 ~ 4 hours. In the adult stage, the feed dosage should be adjusted according to the weather, the growth and feeding of loach. The residual bait should be removed in time.
Extended data:
Generally, a cement pond or a concrete pond is used to raise loach in ponds, with a depth of 70 ~ 100 cm and a water depth of 50 ~ 60 cm. The bottom of the pond is covered with 15 ~ 20 cm thick mud, and the pond area can be large or small, preferably 2 ~ 3 mu. The pond should be convenient for irrigation and drainage, and the entrance and exit should be protected by barbed wire. Before stocking, the pond should be cleaned and disinfected, and the method and dosage are the same as those of the fry pond. If there is no quicklime, it can also be disinfected with bleaching powder, with a dosage of 4 ~ 5 kg per mu. If possible, you can set up a fish pit in the middle of the pond near the drain to facilitate fishing in the future.
Before loach seedlings enters the pond, it should also be fertilized to promote the reproduction of plankton in the water. After 2-5 days of fertilization, loach species can go to the pond. Stock 30 ~ 50 kilograms per mu, which can be increased when water resources are abundant. According to the water quality of the pond, some organic and inorganic fertilizers should be applied frequently to improve the water quality. In addition, a certain amount of artificial bait should be fed every day. Feed types include maggots, fish meal, pig blood meal, silkworm chrysalis powder, rice bran, wheat bran, vegetable cake and so on. According to different seasons, the feeding amount can be different.
May to June is 4% ~ 5% of the loach's weight; 8% ~10% in July and August; 5% ~ 6% from September to 65438+1October. The bait table should be set in the pond, and the bait should be placed on the food table. Each pond can be equipped with 3 ~ 4 bait tables according to the size. Check the feeding situation before feeding, and reduce the feeding amount if you don't finish eating. Generally, it should be eaten 2 ~ 4 hours after feeding, and the bait table should be cleaned every 3 ~ 5 days to prevent disease. Fresh water should be injected into the pond frequently to maintain a good water quality environment. The pool water should be kept neutral or weakly acidic, and disinfected regularly (15 ~ 30 days) with 1 ~ 2 ppm bleaching powder to achieve the purpose of sterilization and disease prevention.
