Problems solved by technology

[0003] At present, the factory culture of Penaeus vannamei has the following problems to be solved: First, the body color of Penaeus vannamei will change with the change of the environment. The body color of prawns is bluish, and poor body color will affect the market demand; second, the density of industrialized cultured prawns is relatively high, and comprehensive and sufficient nutrition is needed to ensure the growth of prawns, but the existing feed nutrition is not comprehensive and balanced enough , the growth rate and survival rate of cultured prawns are low; third, industrialized cultured prawns generally have a large area and need to be fed with more feed. In order to save manpower input, feeders are generally used for feeding. Insufficient hardness and hardness, the powder output rate is high during the feeding production process of the feeder, and a thick layer of powder will be produced around the feeder after a period of use, which not only causes waste of feed, but also pollutes water quality

Embodiment 1

[0036] A kind of preparation method of the special-purpose feed of industrialized farming Penaeus vannamei of the present embodiment is as follows:

[0037] Step a. Weigh 12 parts of peanut bran, 24 parts of soybean meal, and 10 parts of fermented soybean meal by weight, put them in a pulverizer for primary crushing, and then pass through a sieve with an aperture of 1 mm to obtain primary crushed materials for later use. ;

[0038] Step b. Weigh 10 parts of raw krill powder, 8 parts of Pakistani fish meal, 3 parts of Tenebrio molitor, 9 parts of puffed meat and bone meal, 12 parts of wheat flour, and 13 parts of tapioca starch by weight, put them in a pulverizer, and add the pulverized materials again After mixing, perform secondary superfine grinding, and pass the crushed material through an 80-mesh sieve to obtain a secondary crushed material with a fineness of more than 95%, so as to ensure the uniformity of the feed and help improve the nutrient absorption rate of the praw...

Embodiment 2

[0045] A kind of preparation method of the special-purpose feed of industrialized farming Penaeus vannamei of the present embodiment is as follows:

[0046] Step a. Weigh 15 parts of peanut bran, 28 parts of soybean meal, and 8 parts of fermented soybean meal in parts by weight, place them in a pulverizer for primary crushing, and then pass through a sieve with an aperture of 1 mm to obtain primary crushed materials for subsequent use. ;

[0047] Step b. Weigh 8 parts of krill meal, 10 parts of Pakistani fish meal, 5 parts of Tenebrio molitor, 12 parts of puffed meat and bone meal, 15 parts of wheat flour, and 15 parts of tapioca starch by weight, put them in a pulverizer, and add the pulverized materials once more After mixing, perform secondary superfine grinding, and pass the crushed material through an 80-mesh sieve to obtain a secondary crushed material with a fineness of more than 95%, so as to ensure the uniformity of the feed and help improve the nutrient absorption ra...

Embodiment 3

[0054] A kind of preparation method of the special-purpose feed of industrialized farming Penaeus vannamei of the present embodiment is as follows:

[0055] Step a. Weigh 10 parts of peanut bran, 20 parts of soybean meal, and 13 parts of fermented soybean meal in parts by weight, put them in a pulverizer for primary crushing, and then pass through a sieve with an aperture of 1 mm to obtain primary crushed materials for later use. ;

[0056] Step b. Weigh 12 parts of krill powder, 6 parts of Pakistani fish meal, 2 parts of Tenebrio molitor, 5-12 parts of puffed meat and bone meal, 10 parts of wheat flour, and 10 parts of tapioca starch by weight, put them in a grinder, and add them again After the pulverized materials are mixed, carry out secondary ultrafine pulverization, and pass the pulverized materials through an 80-mesh sieve to obtain secondary pulverized materials with a fineness of more than 95%, so as to ensure the uniformity of the feed and improve the nutrient absorp...

Abstract

The invention relates to the technical field of aquaculture feed, in particular to special feed for industrial aquaculture of penaeus vannamei boone and a preparation method of the special feed. The special feed is prepared from the following components in parts by weight: 6-15 parts of krill meal, 5-10 parts of BASSTER fish meal, 2-5 parts of tenebrio molitor, 5-12 parts of expanded meat and bone meal, 8-15 parts of peanut bran, 18-30 parts of soybean meal, 5-15 parts of fermented soybean meal, 3-15 parts of grease, 8-15 parts of wheat flour, 8-15 parts of cassava starch, 0.3-0.8 parts of kelp powder, 1-5 parts of spirulina powder, 0.1-0.5 parts of chlorella powder, 0.01-0.2 parts of Haematococcus pluvialis powder, 0.1-0.4 parts of bile acid, 0.1-0.5 parts of Eucommia leaf extract and the like. The special feed is comprehensive in nutrition, capable of remarkably increasing the long-speed survival rate of the Nanmen white shrimps, suitable for production of a batch feeder, low in powder yield, capable of improving the body color of the shrimps and better suitable for industrial aquaculture requirements.

Description

technical field [0001] The invention relates to the technical field of aquaculture feed, in particular to a special feed for industrialized culture of Penaeus vannamei and a preparation method thereof. Background technique [0002] Industrial farming refers to a high-density, high-yield farming method that uses advanced mechanical and electronic equipment to control the temperature, light, dissolved oxygen, pH value, feeding amount and other factors of the aquaculture water in an indoor seawater pool. Due to over-exploitation, not only domestically, but also the whole world is facing problems such as epidemics and environmental pollution. At the same time, with the increasing demand for high-quality aquatic products, traditional farming techniques and models have been difficult to solve the current problems and meet the needs of emerging markets. . Therefore, the limitations of the traditional farming model need to be replaced by a new farming model, and the factory farming...
