Misgurnus anguillicaudatus breeding feed used at water temperature of below 20 DEG C

Abstract

The invention discloses a misgurnus anguillicaudatus breeding feed used at a water temperature of below 20 DEG C, and relates to the field of aquaculture. The protein content is controlled at 28%-30% of the total mass of the feed, and the feed is prepared from the following baits by mass percentage: 25%-30% of an animal bait comprising 10-15 parts by weight of a locust powder, 15-23 parts by weight of a trash fish powder, 10-15 parts by weight of a conch meat powder, and 15-20 parts by weight of a tenebrio molitor powder; and 65%-80% of a plant bait comprising 10-16 parts of oat flour, 10-15 of corn flour, 6-10 parts of soybean cake meal, 8-15 parts of a vegetable powder, and 6-12 parts of a sweet potato powder. The invention is rich in nutrition, not only contains the animal feed and can meet the hobby of misgurnus anguillicaudatus on the fish flesh bait, but also contains the plant feed, and can avoid the respiratory frequency from being rapidly increased because the misgurnus anguillicaudatus continuously eats high protein feeds, so as to avoid floating on a water surface or death; the contained natural baits are particularly applicable for small misgurnus anguillicaudatus to eat, and the feed is suitable for use at the water temperature of below 20 DEG C, and can avoid excessive stuffing of intestinal tracts so as to avoid affecting intestinal breathing; and the misgurnus anguillicaudatus is fast in growth speed and high in survival rate.

Description

technical field

[0001] The invention relates to the field of aquaculture, in particular to a loach breeding feed used at a water temperature below 20°C. Background technique

[0002] Loach (Misgurnus anguillicaudatus) has high nutritional and medicinal value. It has a large demand in the domestic and foreign markets, and the price is relatively good. The artificial breeding has high profits and quick results, and the breeding prospect is promising. The breeding area of ​​loach in China is 15 million to 20 million square meters, mainly concentrated in Jiangsu, Henan, Hubei, Shandong, Anhui and Sichuan, and the breeding mode is mainly pond seine farming with soil. At present, the main factor that restricts the efficiency of loach farming is that the growth rate of loach is slow, and the annual growth rate is difficult to reach more than 3 times; the feed utilization rate is extremely low, and the bait coefficient is generally between 4.0 and 6.0, and some even as high as 8.0, ...
