Embodiment 1

[0006] Embodiment 1: Get 100 kilograms of clean raw soybeans, 4 kilograms of boiled cooked lard and 0.5 kilogram of salt for batching. When making, the soybeans are first fried, then pulverized with a pulverizer, and sieved with a 60-mesh sieve to obtain Cooked soybean powder, melt the lard and cool it to about 18°C, take 4.5 times the weight of the original salt, that is, 2.25 kg of water, dissolve the salt into a water-salt solution, and finally mix the cooked soybean powder, lard, and water-salt solution evenly get the product.

Embodiment 2

[0007] Embodiment 2: Get 100 kilograms of clean raw soybeans, 10 kilograms of boiled cooked lard and 2.5 kilograms of industrial salt for batching. During production, the soybeans are first fried, then pulverized with a pulverizer, and sieved with an 80-mesh sieve Separate the cooked soybean powder, melt the lard and cool it to about 24°C, take 5.5 times the weight of industrial salt, that is, 13.75 kg of water, dissolve the salt into a water-salt solution, and finally mix the cooked soybean powder, lard, water and salt The solution is mixed and stirred evenly to obtain the product. The product is the opening bait for naked carp carp in Qinghai Lake.

Abstract

The invention belongs to the technical field of Qinghai lake naked carp bait, in particular relates to an opening bait for feeding the Qinghai lake naked carp larva, wherein the bait comprises yellow bean, lard and salt at a ratio of 100:4-10:0.5-2.5; the preparation method comprises the following steps: preparing the raw materials by weight, frying the yellow bean, crushing by a crusher, sievingby a sieve having less than or equal to 60 meshes, obtaining the ripe yellow bean powder, melting the lard and cooling to 18-24 degrees centigrade, getting 4.5-5.5 times of water, dissolving the saltand getting the salt solution, uniformly mixing the ripe yellow bean powder, lard and salt solution to get the product. The bait is convenient to get raw materials, has rich nutrition and low cost, and is used for feeding fish larva and fish fry; the dish fry will be rapidly grown; after fed for 15 days, the fish fry will be 2.3cm long; thus the feeding cost is greatly reduced.

Description

1. Technical field: [0001] The invention belongs to the technical field of Qinghai Lake naked carp bait, in particular to an open bait for feeding Qinghai Lake naked carp larvae. 2. Background technology: [0002] Qinghai Lake is the largest plateau saltwater lake in my country. Its fishery resources have been in a state of overall decline. The fish in the lake are mainly naked carp in Qinghai Lake. In order to restore the naked carp resources in Qinghai Lake, the provincial government has closed the lake for ten years. Breeding fish, and using artificial breeding and releasing, that is, artificial breeding and releasing fish fry of Qinghai Lake naked carp. The open bait of naked carp larvae in Qinghai Lake is the basis for cultivating released fry. After the fertilized eggs hatch under natural conditions, the larvae of rotifers, cladocerans, and copepods are used as open bait, and they can grow to 2.3 cm after 15 to 20 days. In the artificial breeding of naked carp fry, the...
