Problems solved by technology

However, with the emergence of diseases and environmental pollution caused by the industrialized cultivation of seawater fish mainly fed with chilled fish, the cultivation of seawater fish cannot meet the requirements of environmental protection and deviates from the sustainable development strategy. The expansion of fish farming and the realization of industrialized production have become difficult problems
Moreover, due to the skyrocketing prices of fishmeal and other main protein raw materials in 2013, some even appeared out of stock.
The tight supply of protein raw materials forces the industry to find new protein sources. In order to solve this problem, scientific and technological personnel of scientific research institutes and enterprises are constantly researching and exploring, and using modern science and technology to improve and innovate the existing protein sources of feed formula. Although Some progress has been made in technology, but there are still technical difficulties that have not been overcome in practical application

Embodiment 1

[0025] A feed formula for artificially breeding seawater fish, preparing 1 ton of seawater fish feed includes: 150kg of wheat, 150kg of rice bran, 130kg of soybean meal, 50kg of rapeseed meal, 25kg of blood cell albumin powder, 80kg of fish meal, 25kg of meat meal, fish, shellfish viscera, Small fish and shrimp fresh aquatic product scraps 398kg, calcium dihydrogen phosphate 15kg, soybean oil 30kg, compound premix 15kg, phytase 0.1kg, Bacillus subtilis 0.4kg, acidogenic Bacillus cereus 0.5kg, yeast 1kg .

[0026] The first step, the mixing ratio of the fermentation strains: weigh each strain according to the following weighing percentage: phytase, Bacillus subtilis, acidogenic Bacillus cereus, yeast, and mix the strains according to the weighing weight;

[0027] The second step, the treatment of aquatic product waste: take fish, shellfish viscera, small fish and shrimp fresh aquatic product leftovers and waste, dry and crush them, and pass through a 40-60 mesh sieve to remove ...

Embodiment 2

[0037] A feed formula for artificially cultured seawater fish, the preparation of 1 ton of seawater fish feed includes: 180.5kg of wheat, 100kg of rice bran, 182kg of soybean meal, 50kg of rapeseed meal, 15kg of blood cell albumin powder, 50kg of fish meal, 30kg of meat meal, fish, shellfish viscera 300kg of leftovers of fresh aquatic products of small fish and shrimp, 20kg of calcium dihydrogen phosphate, 50kg of soybean oil, 20kg of compound premix, 0.3kg of phytase, 0.6kg of Bacillus subtilis, 0.8kg of acid-producing Bacillus cereus, yeast 0.8kg.

[0038] The first step, the mixing ratio of the fermentation strains: weigh each strain according to the following weighing percentage: phytase, Bacillus subtilis, acidogenic Bacillus cereus, yeast, and mix the strains according to the weighing weight;

[0039] The second step, the treatment of aquatic product waste: take fish, shellfish viscera, small fish and shrimp fresh aquatic product leftovers and waste, dry and crush them, ...

experiment example

[0049] In May 2014, the product of the present invention was carried out in the aquaculture farm of Sheyang Farm, Jiangsu Province for fishmeal substitution comparison test. Five seawater fish breeding block fish ponds with the same area were selected, and each fish pond had an area of ​​0.5 mu. 1,000 6-month-old seawater fry were put into the pond, and the experimental results were as follows:

[0050] sea ​​fish Feeding days Feeding amount (g) Average weight gain at the end of the period (g) Survival rate (%) chilled fish bait 60 2000 380 70 Commercially available bait A 60 1300 350 85 Commercially available bait B 60 1200 335 88 Commercially available bait C 60 1000 366 80 Feed of the present invention 60 800 385 98

[0051] These results fully illustrate: the product of the present invention is a relatively ideal animal protein feed, and is an excellent choice to replace fish meal.

Abstract

The invention discloses a feed formula for artificially breeding saltwater fish and a processing method of the feed formula. The feed contains wheat, rice bran, soya bean meal, rapeseed meal, hemoglobin powder, fish meal, meat meal, fish, shellfish viscera, leftovers of fresh aquatic products, namely small fishes and shrimps, monocalcium phosphate, soybean oil, compound premix, phytase, bacillus subtilis, acid-producing bacillus cereus and saccharomycetes. Partial feed ingredients are subjected to microbial fermentation treatment through an advanced processing technology. The feed is a novel feed product capable of replacing the fish meal, so that the feed cost can be effectively reduced; various amino acids and microelements required for breeding saltwater fish are provided; meanwhile, the immunity of the bred saltwater fish is improved, the growth cycle and the disease resistance of the saltwater fish are promoted and the pond yield is improved.

Description

technical field [0001] The invention belongs to the technical field of aquatic feed, in particular to a feed formula for artificially cultured seawater fish and a processing method thereof. Background technique [0002] Since my country's reform and opening up, the national economy has grown rapidly, "scientific and technological innovation, independent innovation" has become the mainstream of today's industrial development, and my country's industry is gradually developing in the direction of intensive, energy-saving, emission-reducing, and low-carbon. my country is the number one country in aquaculture in the world and the only country in the world where aquaculture production exceeds fishing production. Aquaculture occupies a very important position in the national economy. In recent years, my country's marine fish farming model has basically achieved the transformation from traditional extensive farming to quasi-industrial farming, and the farming of marine fish produces...
