Environment protection formula feed for sea water fish

Abstract

The invention relates to a marine-fish environmental protective compound feed, consisting of the following materials in weight ratio: 13 to 20 portions of domestic fish powder, 8 to 15 portions of biological fish meal ABP600, 8 to 12 portions of soybean meal, 10 to 18 portions of peanut bran, 3 to 10 portions of corn, 3 to 7 portions of cotton seed meal, 3 to 7 portions of rapeseeds meal, 3 to 5 portions of meat and bone meal, 3 to 5 portionsof squid bowels powder, 20 to 30 portions of high gluten flour, 1.0 to 3.0 portions of blood meal, 1.0 to 2.0 portions of soybean lecithin, 2.0 to 3.0 portions of marine-fish oil, 0.3 to 0.6 portions of choline chloride (50%), 0.05 to 0.1 portions of Vitamin C phosphate (35%), 0.15 to 1.5 portions of calcium biphosphate, 0.2 to 0.5 portions of compound multiplex vitamin, 0.5 to 1.5 portions of compound mineral salt, 0.1 to 0.3 portions of feed attractant, 0.1 to 0.3 portions of micro-bio-preparation, 0.03 to 0.08 portions of A3Alpha peptidoglycan, 0.01 to 0.04 portions of phytase, and 0.04 to 0.08 portions of non-starch polysaccharase. The compound foodstuff can meet the nutrition demands of such high density cultivated marine fishes such as weever, large yellow croaker, American red fish, sparidae fishes, and trachinotus ovatus and rudd etc, and the cultivated objects can rapidly grow and has high foodstuff conversion rate; the compound foodstuff can intensify the immunity and anti-stress ability of fishes and endow them with good vitality, vivid body color and high survival rate; compared with marine fished cultivated by other foodstuffs, the excretion rates of nitrogen and phosphorous of the marine fishes cultivated by the compound foodstuffs is lowered by 10 to 15 percent, and cause smaller contamination to the cultivation water body.

Description

technical field [0001] The invention relates to the field of aquaculture feed, in particular to an environment-friendly compound feed for seawater fish. Background technique [0002] my country is the number one country in aquaculture in the world, and it is also 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 aquaculture industry has developed vigorously, especially the fourth wave of aquaculture represented by marine fish farming is in the ascendant. However, due to the insufficient international and domestic research on marine fish nutrition, most of their feed formulas are determined by reference to existing international aquaculture products or based on experience. If the price of marine fish remains high, the cost of aquaculture feed may be higher than its market price; at the same time, due to the unreasonable feed formula, exce...

Problems solved by technology

However, due to the insufficient international and domestic research on marine fish nutrition, most of their feed formulas are determined by reference to existing international aquaculture products or based on experience. If the price of marine fish remains high, the cost of aquaculture feed may be higher than its market price; at the same time, due to the unreasonable feed formula, excessive nitrogen and phosphorus discharge in the feed will seriously pollute the aquaculture water; due to high-density intensive The immune function and anti-stress ability of seawater fish are reduced, and the survival rate of seawater fish is not high; coupled with the current variety of seawater fish farming and practical difficulties in production operations, it is difficult to design economical and reasonable solutions for each type of seawater fish. feed formula

This situation has seriously hindered the further development of marine fish farming industry
