Description

A kind of environmental protection, nutrient efficient type sunfish feed

Technical field

The present invention relates to a kind of sunfish feed, relate in particular to a kind of environmental protection, nutrient efficient type sunfish feed; Belong to fish meal technical field.

Background technology

Sunfish formal name used at school is Bluegill (Lepomis marochirus), is under the jurisdiction of Perciformes, Sunfishes, sunfish genus.Originate in North America, within 1987, introduce parallel popularization of China and cultivate.Bluegill is small-sized temperate water fishes, likeness in form bolti; Strong adaptability, feeding habits are mixed, zooplankter and the aquatic insect classes such as staple food wheel animalcule, cladocera, Copepods.Fast growth, easily raise and train that easy raising, lower oxygen concentration resistance, disease are few, population yield advantages of higher.This fish bodily form is graceful, beautiful in colour, and trunk is high containing meat rate, fine and tender taste, nutritious, very easily rise to the bait, and be to eat, view and admire, swim the excellent fish of angling cultivation, in China, there is wide cultivation development prospect.

China's sunfish breeding way is various, common are pond monoculture, pond fish farming, raises together with the fish such as eel, and put in a suitable place to breed in reservoir, lake, as breeding way such as pet fish, trip fishing intensive cultures.This fish in Hunan, the ground cultured area such as Hubei, Guangdong, Fujian is very wide, economic benefit is high; The management method of rational cultivation density and high-quality, this fish mu profit can reach more than ten thousand yuan.

Along with culture fishery development, sunfish cultivation is constantly concentrated, the burden that high density, intensive cultivation cause breeding environment is more and more heavier, residual bait, excreta, germ etc. are more and more serious to the pollution of water body, and various places plant constantly breaks out sunfish and drops in production over a large area because water quality deterioration or disease cause cultivation.In addition, along with the raising of people's living standard, people are from pursuing and change gradually the pursuit to quality now into protein quantity before, and people more trend towards the beautiful cultured product of body colour when choosing sunfish.Sunfish is as pet fish and trip fishing simultaneously, and its beautiful body colour is hobby that people pursue more.Although the patent about sunfish feed formula has been reported at present, but the design of these feed formulas does not take into full account harm that under current high-density breeding, sunfish self excreta, residual bait etc. cause breeding environment and breeding environment worsens the harm to cultivated animals, the consideration that simultaneously affected by feed for sunfish as pet fish or the fish body colour of fishing is also not in place.

Therefore, be necessary the sunfish expanding compound feed developing a kind of environmental protection, nutrient efficient, can maintain beautiful body colour, to promote the sustainable development of China's sunfish aquaculture, aquaculture feed industry, recreational fisheries.

Summary of the invention

The object of the present invention is to provide the sunfish feed of a kind of environmental protection, nutrient efficient, to improve the growth performance, immunity of sunfish and to food utilization efficiency, maintain its beautiful body colour, reduce residual bait, the pollution of excreta to breeding environment, increase the yield per unit area and benefit sunfish feed.

For solving the problems of the technologies described above, technical scheme provided by the invention is such: this environmental protection, nutrient efficient type sunfish feed consists of the component of following mass percent: flour 20.0% ~ 25.0%, digested tankage 3.0% ~ 10.0%, fish meal 25.0% ~ 38.0%, peanut meal 6.0%, cuttlefish cream 1.0% ~ 2.0%, dregs of beans 15.0% ~ 25.0%, fish oil 1.0% ~ 3.0%, soybean oil 2.0% ~ 5.0%, calcium dihydrogen phosphate 0.5 ~ 1.0%, B B-complex 0.3% ~ 0.5%, composite mineral matter 0.5% ~ 1.0%, mould inhibitor 0.03% ~ 0.05%, Choline Chloride 0.1%, astaxanthin 0.05%, each component sum is 100%.。

Above-mentioned environmental protection, nutrient efficient type sunfish feed, component by following mass percent forms: flour 21.0% ~ 24.0%, digested tankage 5.0% ~ 8.0%, fish meal 28.0% ~ 33.0%, peanut meal 6.0%, cuttlefish cream 1.0% ~ 2.0%, dregs of beans 18.0% ~ 22.0%, fish oil 1.0% ~ 3.0%, soybean oil 3.0% ~ 4.0%, calcium dihydrogen phosphate 0.5 ~ 1.0%, B B-complex 0.3% ~ 0.5%, composite mineral matter 0.5% ~ 1.0%, mould inhibitor 0.03% ~ 0.05%, Choline Chloride 0.1%, astaxanthin 0.05%, each component sum is 100%.。

Further, above-mentioned environmental protection, nutrient efficient type sunfish feed, described mould inhibitor be mould must gram Midew preventive for feed; Described composite mineral matter is the omnivorefish microelement pre-mix material of Guangdong Tong Wei feed corporation,Ltd; Described B B-complex is the omnivorefish vitamin premix of Guangdong Tong Wei feed corporation,Ltd.

Compare with existing formula technique, the present invention has the following advantages:

1. feed provided by the invention be take sunfish the apparent digestibility of the bulk raw materials such as fish meal, dregs of beans, peanut meal is according to selecting each relevant feedstuff, simultaneously the thick protein in feed formula and total energy content are that to take the digestible protein of sunfish and digestible energy be according to design, based on the micro-equilibrium principle of amino acid, reasonably combined every bulk raw material, to meet the growth needs of sunfish, improve the utilization rate of sunfish to feed protein simultaneously, reduce the pollution of N discharge to breeding water body in metabolic waste.

2. feed provided by the invention reduces fish meal consumption and improves vegetable protein consumption, can reduce the discharge of feed formula cost and phosphorus; Can improve the utilization rate of Dietary phosphorus, reduce the pollution of phosphorus to breeding water body, prevent that N∶P ratio is unbalance and cause body eutrophication.

3. feed provided by the invention adds a certain amount of astaxanthin, can maintain the beautiful body colour of sunfish, promotes its market value.

4. feed provided by the invention, various raw materials easily obtain, and formulation cost is low, easily promotes.
