Problems solved by technology

However, with the provision of people's living standards, the demand for fish meat is large, and the breeding density of many ponds is getting higher and higher. Residual feed, feces, etc. cause the increase of bacteria in the water body, which greatly increases the number of silver carp and bighead carp, which are filter-feeding fish. There is an urgent need for a feed for silver carp and bighead carp in polyculture mode to enhance the physique of silver carp and bighead carp

preparation example Construction

[0031] A method for preparing the above-mentioned compound feed for mixed culture of silver carp, bighead carp and herring comprises a sinking feed preparation step and a floating feed preparation step.

[0032] Among them, the sinking feed preparation steps include: 10-20 parts of fish meal, 10-20 parts of green shrimp powder, 10-20 parts of sweet potato powder, 5-10 parts of loach powder, 10-20 parts of silkworm chrysalis powder, 10-20 parts of bean cake powder 10-20 parts of snail powder, 1-2 parts of calcium dihydrogen phosphate, 1-5 parts of linolenic acid, 1-5 parts of linoleic acid, 0.5-1 part of vitamin premix, 0.5-1 part of amino acid premix , and 0.5 to 1 part of the mineral premix are mixed, crushed into powder, and granulated. Preferably, the raw materials are mixed and pulverized into powders of 10-50 meshes, and aged at 50-60°C. The aging temperature should not be too high to avoid vitamin damage. After aging, it is processed into columnar particles with a diame...

Embodiment 1

[0037] The invention provides a compound feed for mixed culture of silver carp, bighead carp and herring, which is prepared by mixing sinking feed and floating feed at a ratio of 1:1.

[0038] Wherein, the raw material of sinking feed is calculated in parts by weight, including: 10 parts of fish meal, 10 parts of green shrimp meal, 10 parts of sweet potato meal, 5 parts of loach meal, 10 parts of silkworm chrysalis meal, 10 parts of bean cake meal, 10 parts of snail meal, 1 part of calcium dihydrogen phosphate, 1 part of linolenic acid, 3 parts of linoleic acid, 0.5 part of vitamin premix, 0.5 part of amino acid premix, and 0.5 part of mineral premix.

[0039] The raw materials of the floating feed are counted in parts by weight, including: 5 parts of soybean meal, 5 parts of rapeseed meal, 5 parts of cotton meal, 3 parts of silkworm chrysalis powder, 1 part of linolenic acid, 1 part of linoleic acid, 2 parts of yeast powder, ginkgo 2 parts of leaves, 2 parts of Houttuynia cor...

Abstract

The invention discloses a compound feed used for polyculture of bighead silver carps and herrings and a preparation method thereof, and relates to the field of fish breeding; and the compound feed used for polyculture of the bighead silver carps and the herrings is composed of a floating feed and a sinking feed. The sinking feed is mainly used for feeding the herrings which live at middle and lower layers of the water; and various animal and plant proteins are used in cooperation so as to provide proteins needed for herring growth. The floating feed is mainly used for feeding the bighead silver carps which live at an upper layer of the water; the floating feed is relatively low in protein content, and is added with various Chinese herbal medicines; and a main purpose of the floating feed is to improve disease resistance of the bighead silver carps. The compound feed adopts different formulas for different fishes so as to avoid nutrient waste; moreover, the compound feed improves survival rate and growth rate of the fishes in polyculture mode so as to increase yield. According to the preparation method of the compound feed used for polyculture of the bighead silver carps and the herrings, differential treatments are carried out during preparation processes according to different feeding habits of the bighead silver carps and the herrings; a fermentation process is added into the preparation processes of the floating feed according to the characteristic of the bighead silver carps, namely fancy on sour rotten foods; and differential feeding of the bighead silver carps and the herrings are ensured.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a compound feed for mixed culture of silver carp, bighead carp and herring and a preparation method thereof. Background technique [0002] Herring belongs to the genus Cyprinidae of Cyprinidae, which is mainly distributed in the plains south of the Yangtze River in my country, and is relatively rare in the north of the Yangtze River. Herring generally likes to live in the lower layer of the water. It is blue-black, with gray-black fins, wide and flat head, mouth end, without beards, and pharyngeal head with molar-like teeth. It is a carnivorous fish that feeds on snails, mussels, shrimps and aquatic insects. [0003] Silver carp belongs to the genus Silver carp of Cyprinidae Cyprinidae and is distributed in major water systems across the country. Its body is flat on the sides, slightly taller, spindle-shaped, blue-gray on the back, white on both sides and abdomen, the pectoral fins ...
