Abstract
The invention discloses a biological flocculating seed source for breeding prawns. The feed coefficient of the traditional prawn feed is 1.2-1.6, the breeding cost is slightly high on the basis of the feed coefficient, and the preparation of the feed with a low feed coefficient is the direction of the progress of the feed technology. The biological flocculating seed source is prepared by a method which comprises the following steps of: according to a weight ratio of clean fresh water to red sugar to rice bran to feed additives is 250:(5-8):(30-40):(2-3), taking red sugar, rice bran and the feed additive and mixing uniformly; adding the mixture into clean fresh water and stirring uniformly; sealing; fermenting for 3-4 days under the environment with the temperature of 25-32 DEG C, thus obtaining the biological flocculating seed source; and every one gram of feed additive contains 10-20 millions bacillus. The feed coefficient when the biological flocculating seed source is used for breeding the prawns is 0.7-0.8; and compared with the traditional feed, the biological flocculating seed source has the advantage that the growth period of the adult prawns is shortened by 15-20 days.
Description
Technical field
What the present invention relates to is a kind of bioflocculation provenance cultivating extra large shrimp, belongs to mariculture technology field.
Background technology
In current shrimp feed formula, based on protein raw material, coordinate calcic raw material, carbohydrate raw material, humatite raw material, trace element materials and vitamin are prepared from.Common shrimp feed formula: high-quality fish meal, dusty yeast, shrimp shell meal, cuttlefish shell powder, flour, organic mineral substance and B B-complex.Such shrimp feed formulation nutrients is comprehensive, can promote the growth of grow shrimp, but also have certain limitation, first be because feed is without fermentation, some protease inhibitors does not obtain sex change, inhibits shrimp absorbing protein, and utilization rate is reduced.Next is the feed without fermentation in preparation process, and microorganism continued growth, the healthy growth of prawn causes very large threat.Be exactly the food that such feed organic matter that can not absorb in culturing pool in cultivating pool forms shrimp again, recycling poor effect.The quality of feed can reflect in feed coefficient, so-called coefficient of raising refers to the quantitatively required forage volume of extra large shrimp growth, the feed coefficient of shrimp aquaculture feed as extra large in above-mentioned tradition is 1.2-1.6, and namely extra large shrimp often grows the feed that 1 kilogram needs 1.2-1.6 kilogram.Such feed coefficient aquaculture cost seems slightly high, and the feed preparing low feed coefficient is the direction of feed technology progress.Shrimp needs excretion in cultivating pool, bait also has residual in culturing pool, these residues and excreta is too many can affect cultivation water, so water will be changed to cultivating pool, change water frequently and just improve aquaculture cost, how to be regulated cultivation water by shrimp feed, be obviously a problem needing solution.By retrieval, do not find throwing something and feeding by breeding feed, solve the technology report of water quality.
Under current extra large shrimp aquaculture becomes the situation of extensive development, aquaculture cost is crossed higher position and is meaned that the market competitiveness reduces, and economic benefit reduces.Therefore, research one reduces feed coefficient, fully effectively utilizes organic bioflocculation provenance in cultivation, is necessary for the market competitiveness improving the extra large shrimp of cultivation.
Summary of the invention
Object of the present invention is just to provide a kind of bioflocculation provenance cultivating extra large shrimp, and reduce feed coefficient, the feed coefficient overcoming traditional shrimp feed is too high, can not make full use of the organic matter in breeding environment, the deficiency of high cost.
Foregoing invention object, is realized by following concrete technical scheme, a kind of bioflocculation provenance cultivating extra large shrimp, is prepared by following method:
According to the ratio that the weight ratio of clean fresh water, brown sugar, rice bran and feed addictive is 250:5-8:30-40:2-3, get brown sugar, rice bran and feed addictive to mix, add in clean fresh water and stir, sealing, at the environment bottom fermentation 3-4 days that temperature is 25-32 DEG C, obtain bioflocculation provenance;
Described feed addictive refer to containing 1-2 10,000,000 bacillus/gram feed addictive.
Take the present invention of above-mentioned measure, it is a kind of bioflocculation provenance, when the present invention is thrown something and fed to extra large shrimp aquaculture pond time, bioflocculation provenance absorbs solidification the metabolite of the suspension in shrimp culture pond, organic matter and prawn rapidly and utilizes, and be converted into self intrinsic thing of bacterium, form solidifying floc sedimentation, solidifying floc sedimentation gets up at the effect low suspension of water-bed oxygenation gas explosion, allow shrimp take food, described water-bed oxygenation refers to by air blast and aeration plate directly to supplemental oxygen at the bottom of culturing pool.The carbon-nitrogen ratio of breeding water body can be regulated by such mode, keep the breeding environment of breeding water body, reduce rate of water exchange, reduce and change waterside number and quantity of exchanged water, thus improve cultivation water environment, protect the overall situation of periphery.The feed coefficient taking the present invention to cultivate extra large shrimp is 0.7-0.8, compared with traditional breeding feed, when supporting equally to adult shrimp, shortens 15-20 days in growth period with the extra large shrimp of the present invention's cultivation.
