Description

A kind of shrimpfish is raised together with special-purpose feed of grass carp

Technical field

The present invention relates to the aquaculture feed field, be specifically related to a kind ofly raise together with grass carp special feed under the pattern shrimpfish.

Background technology

Penaeus Vannmei is one of three the highest big good shrimp species of the cultured output of generally acknowledging in the world today, but at present under high density intensive culture pattern, the disease of Penaeus Vannmei is serious day by day.For reducing the breed risk of Penaeus Vannmei, the pattern that shrimpfish is raised together with is widely used.Penaeus Vannmei is mainly lived in pond bottom, just swim over to pool side or waters at the middle and upper levels when only looking for food, and grass carp belongs to pelagic fishes, mainly waters activity at the middle and upper levels in the pond, and the two life waters difference more can be utilized the pond load capacity.Grass carp is an ominivore-fish, happiness food grass, also eat animal feed, the sick shrimp of early stage can ingest, prevent the further propagation and the diffusion of disease, simultaneously relatively other ominivore-fish and predacious fish, grass carp to the predation of healthy shrimp relative with the ability of the shrimp material of ingesting a little less than, raise together with shrimpfish at present therefore that grass carp is the main kind of raising together with in the process.Grass carp and shrimp are raised together with and can also improve the pond life diversity, promote pond material circulation, stablize pond water quality.

But at present also there is following defective in the shrimpfish pattern of promoting of raising together with: it is on the low side that 1, shrimpfish is raised together with in the pool grass carp breeding density, generally is controlled at 30 tail/mus, about 1 jin of specification; Can not give full play to the productivity in pond; Owing to there is not supporting feed of grass carp, too high grass carp breeding density can improve the feed coefficient of prawn, reduces the benefit in pond on the contrary; 2, culturing the later stage, grass carp is owing to the shrimp material and the sick shrimp of the top grade of ingesting for a long time, and the length of enteron aisle is reduction significantly, the obvious pathology of liver meeting, and then reduce the prey ability of grass carp to sick shrimp; 3, raise together with in the pond shrimpfish, the ingest shrimp material or the grass carp intensive culture material of high nutrition of grass carp all can make the coefficient of condition of grass carp higher, makes the not anti-transportation of grass carp, and raising together with the pool grass carp price during results can be more on the low side than the market price.4, in the process that shrimpfish is raised together with, along with the carrying out of culturing, the pond water quality eutrophication is serious, and grass carp is more limited to the improving effect of water quality, therefore the later stage prawn through regular meeting occur raising the nose above water to breathe, problem such as irritability corpus hemorrhagicum and nitrite exceed standard.

At present shrimpfish is raised together with in the pattern, and grass carp is feeding not substantially, or directly adopts grass carp intensive culture material to raise.

Therefore a kind of shrimpfish of needs exploitation is raised together with the grass carp special feed in the pattern, improves the trophic level of material that grass carp ingests, and gives full play to the advantage of grass carp, improves pond utilization rate and benefit.

Open day on March 19th, 2008 of Chinese patent publication number CN101142969() disclosing a kind of grass carp uses pellet, and composition is soya-bean cake 10-20 part, rape cake 15-25 part, cottonseed cake 10-20 part, wheat bran 10-19 part, inferior powder 10-15 part, rice bran 10-20 part, fish meal 3-6 part, stone flour 1-2.5 part, salt 0.1-0.5 part, cactus dry powder 0.4-0.6 part, aloe dry powder 0.3-0.5 part, garlic dry powder 0.1-0.3 part, probiotics preparation 0.2-0.6 part.This grass carp only is used for grass carp with pellet and cultures the pool.

Summary of the invention

The object of the present invention is to provide a kind of shrimpfish to raise together with the feed of grass carp of pool special use, reach the reduction shrimpfish by this feed and raise together with the feed coefficient of pool Prawn material, improve the coefficient of condition of grass carp, improve breed later stage grass carp prawn disease control ability and the purpose that promotes grass carp in the water quality adjustment function in later stage.

The present invention is achieved through the following technical solutions:

A kind of shrimpfish is raised together with special-purpose feed of grass carp, comprise following several raw material: the dish dregs of rice, cotton dregs, DDGS(Distillers Dried Grains with Solubles, vinasse protein feed), grass meal, brewex's grains, probiotics, l-cn, adhesive, composite mineral salt trace element.By weight percentage, the proportioning of above-mentioned substance is: the dish dregs of rice 10 ~ 20%, cotton dregs 5 ~ 10%, wheat 20 ~ 30%, DDGS 5 ~ 20%, grass meal 10 ~ 20%, brewex's grains 5 ~ 20%, compound micro-ecological preparation 0.1 ~ 1%, l-cn 0.02 ~ 0.04%, composite mineral salt trace element 2.5 ~ 4%, filler surplus.

As a kind of preferred version, the proportioning of above-mentioned raw materials is: (effective bacterium number of bacillus is 2*10 for the dish dregs of rice 15 ~ 20%, cotton dregs 10%, wheat 20%, DDGS 10 ~ 20%, grass meal 10%, brewex's grains 15 ~ 20%, compound micro-ecological preparation ¹⁰Cfu/g) 0.5%, l-cn 0.02%, composite mineral salt trace element 2.5%, filler surplus.
