specific Embodiment approach 1

[0009] Specific embodiment one: present embodiment leptospirosis larvae artificial opening feed is by mass parts by the Peruvian fishmeal of 20~35 parts, the Norwegian fishmeal of 10~25 parts, the fish oil of 3~5 parts, the soybean oil of 5~7 parts, 3-5 parts of soybean lecithin, 5-8 parts of whole egg powder, 5-8 parts of milk powder, 3-6 parts of frozen water earthworm powder, 3-6 parts of algae powder, 0.5-1 part of betaine, 2-4 parts of cooked starch, 7-9 parts of multivitamins, 3-5 parts of mixed mineral salts, 1-3 parts of carboxymethyl cellulose and 0.01-0.5 parts of vitamin E.

[0010] The preparation method of the artificial opening feed for larvae larvae in this embodiment is as follows: after the Peruvian fish meal and Norwegian fish meal are filtered through a 60-mesh sieve, weigh the various components of the artificial opening feed for larvae larvae according to the number of parts, and stir evenly , gradually add water and stir until dough is formed, knead on a ...

specific Embodiment approach 2

[0012] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the artificial opening feed for larvae larvae consists of 25 to 30 parts of Peruvian fish meal, 12 to 22 parts of Norwegian fish meal, and 3.5 to 4.5 parts of fish meal by mass. Fish oil, 5.5-6.5 parts of soybean oil, 3.5-4.5 parts of soybean lecithin, 5.5-7.5 parts of whole egg powder, 5.5-7.5 parts of milk powder, 3.5-5.5 parts of frozen water worm powder, 3.5-5.5 parts of algae powder , 0.6-0.8 parts of betaine, 2.5-3.5 parts of cooked starch, 7.5-8.5 parts of multivitamins, 3.5-4.5 parts of mixed mineral salts, 1.5-2.5 parts of carboxymethyl cellulose and 0.05-0.4 parts composition of vitamin E. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0013] Specific embodiment three: what this embodiment is different from specific embodiment one is that the artificial opening feed of leptospirosis is made of 30 parts of Peruvian fish meal, 15 parts of Norwegian fish meal, 4 parts of fish oil, and 6 parts of soybean oil by mass. , 4 parts of soybean lecithin, 6 parts of whole egg powder, 7 parts of milk powder, 5 parts of frozen water earthworm powder, 5 parts of algae powder, 1 part of betaine, 3 parts of cooked starch, 8 parts of various Vitamins, 4 parts of mixed mineral salts, 1.95 parts of carboxymethylcellulose and 0.05 parts of vitamin E. Others are the same as in the first embodiment.

Abstract

The invention discloses an artificial hatch feed for brachymystax lenok fry, and relates to an artificial hatch feed for fry. The feed solves the problems that the conventional artificial hatch feed for the brachymystax lenok fry is high in labor intensity of workers, high in raising cost and difficult to breed large-batch fry. The artificial hatch feed for the brachymystax lenok fry consists of Peruvian fish meal, Norwegian fish meal, fish oil, soybean oil, soybean lecithin, whole egg powder, milk powder, chilled water earthworm powder, algae powder, betaine, cooked starch, multiple vitamins, mixed mineral salt, carboxymethylcellulose and vitamin E. By using the artificial hatch feed for the brachymystax lenok fry, the breeding survival rate and the weight of the fry are increased in a breeding period of 30 days and do not have remarkable difference compared with live bait for transition hatch breeding, the cost of the feed is reduced by over 60 percent, 50 percent of persons are saved, the cost of the feed is low, the labor intensity of the persons is reduced, hatch and domestication of the brachymystax lenok fry can be performed in batch, and a firm foundation is laid for breeding commercial fish in a large scale.

Description

technical field [0001] The invention relates to an artificial opening feed for larvae. Background technique [0002] Brachymystax lenok, formerly known as Brachymystax lenok, small red eye. In China, it is mainly distributed in Northeast China, Hebei, Shanxi, Gansu, Xinjiang, Inner Mongolia, and Qinling Mountains. It is a rare cold-water fish in my country. In recent years, due to environmental changes and human activities, the resources of leptospirosis have declined sharply. has become a vulnerable species. Leptospirosis is sexually mature in 4-5 years in nature, and its feeding habits are mainly aquatic insects. At present, the larvae can be fully artificially propagated, and artificial breeding has been carried out in Northeast China, Shandong, Hebei, Xinjiang and other places, but there has been no artificial feed for larvae, all of which use daphnia------- Water worms --- water worms + feed --- feed is gradually domesticated, and there are problems in the purchase an...
