Rice sprouts are good fodder for fish

After sprouting and feeding fish, grain has the advantages of wide range of raw materials, simple production, rich nutrition, strong palatability, convenient feeding, low cost and so on. In addition, it can also alleviate the contradiction between concentrate feed and green feed, so it is a kind of fishery feed worth popularizing. Cereal sprouts are rich in vitamins and carotene. Using millet sprouts @ # @ 233 grains @ can promote the transformation and metabolism of nutrients and enhance the antibacterial ability of skin, especially for prenatal cultivation of herbivorous fish such as grass carp, common carp and carp, which can improve the spawning rate, fertilization rate and survival rate. The production and feeding methods of grain sprouts are introduced as follows:

First, production.

The seeds of barley, rice and other cereals were screened, washed and dried, and soaked in warm water of 25 ℃ ~ 30 ℃ for one day and night. After the seed expands, it is spread out in a wooden plate or other water filter, with a thickness of 3 cm ~ 5 cm, covered with gauze or gunny sacks, and kept at 18 ℃ ~ 25 ℃ at room temperature. Spraying about 30 ℃ of warm water every day and night for 3 ~ 4 times, and turning it slightly at the same time, hair roots and germs can grow after 2 ~ 3 days, then remove gauze or sack pieces, about 5 ~ 7 days, buds grow out, and the length of grain buds can be controlled as needed to feed the fish.

Second, feeding.

The species that like to eat grain sprouts are grass carp, carp and carp. Dissection found that green carp, silver carp and bighead carp also eat grain sprouts. The feeding time can be from late April to early November. Feeding grain sprouts can not only solve the problem of shortage of fish and grass, but also help to promote fat and gain weight, but also reduce the cost. The sprouts should be fixed, timed and quantified. The daily feeding amount is generally 5% of the total body weight of the fish. If the total weight of the fish in the water is not estimated, it can be checked 4 hours after sprouting. If there is no remaining sprout in the food field, the amount of sprouting should be increased appropriately, and there are a small amount of sprouts left on the food field, indicating that the dosage is appropriate.
