Abstract
The invention discloses a prawn nutrition intensifier. The prawn nutrition intensifier is prepared by mixing selenium-rich feed mixtures and medical stones at the weight ratio of 0.1-10:50-100, wherein the preparation process of the selenium-rich feed mixtures comprises the following steps of: weighing selenium-rich raw materials and feed raw materials in proportion, and sufficiently stirring and uniformly mixing respectively for standby; mixing the selenium-rich raw materials and the feed raw materials at the mass ratio of 1:2-10; and enabling the product particle size of a final product to be at a nanometer grade. The product prepared by the method disclosed by the invention is suitable for culturing selenium-rich prawns and obvious in effect and has important practical significance on developing selenium-rich prawn aquaculture.
Description
Technical field
The present invention relates generally to field of marine product cultivation technology, is specifically related to a kind of prawn nutrition enhancer.
Background technology
Prawn is a kind of important seawater economy cultivation kind.Belong to Arthropoda, Crustachia, Decapoda, Penaeidae, Penaeus.Penaeus is individual large, the common name prawn.The prawn health is long and slightly flat-sided, gonochorism, and adult frog shrimp is greater than male shrimp, and body colour is also different; The female shrimp body colour ash of Chinese prawn is blue or green, male shrimp body colour jaundice.The external chitinous ectoskeleton crust of one deck that is being coated with of prawn, it is formed by the epidermal cell secretion of its below.Long general 16～22 centimetres of the individual body of female growth heavily approximately 50～80 restrains, and maximum reaches 30 centimetres, weighs 250 grams; Male less, long 13～18 centimetres of body weighs 30～50 grams.Prawn is wide temperature eurysalinity aquatic/marine animals.Body is long tubular, and the left and right sides is flat-sided, and health is divided into head, chest and belly, is comprised of 20 body segments.Belly is longer, and is muscular, and merogenesis is obvious.Often dwell in the seabed, shallow sea.The happiness food end dwell small-sized shell-fish, bivalve and other invertebrates, marine alga also ingests.Prawn distributes more extensive, and coastal area of china all produces, and mainly is distributed in the Huanghai Sea, the Bohai Sea and Korea peninsula Western Coast.Economic worth is high, is the main shrimps in culture of coastal area of china.
It is reported, the shrimp culture pond of 200,000 hectares (3,000,000 mus) although China has an appointment, but the per unit area yield of China's prawn culturing is very low, and as the seabeach resource of shrimp pond exploitation, as other resources, also be very limited, shrimp culture industry develops into today, and next step key is to improve per unit area yield and benefit.Therefore transform " aging shrimp pond ", namely intensive transformation is implemented in aging shrimp pond, by intensive transformation, the prospect that improves average per unit area yield is very wide.The popular of shrimp disease brought huge economic loss to shrimp farming, therefore, although the cultivation of Penaeus Vannmei yet there are no large disease, but will accomplish to prevent trouble before it happens.Because the abuse of antibiolics class also comes serious consequence, has destroyed the breeding ecological environment, along with the adding of WTO, both at home and abroad will be more and more stricter for the check to shrimp products.Therefore we must attract great attention.For the control of shrimp disease, " relying mainly on prevention " must strictly limit the use of relevant antibiotic and other chemicalses, the management of aquaculture wastewater, effective breeding ecological environment, the sustainable and healthy development of guarantee shrimp culture industry.
Present prawn culturing industry relies on artificial bait throwing in basically.Bait throwing in should be accomplished relatively reasonable, should satisfy the healthy Fast Growth of prawn, takes into account again water body environment.The feed of therefore, throwing something and feeding should select be fit to that prawn efficiently increases weight, breeding and disease-resistant kind.For alleviating the pollution pressure in breeding process Prawn pond, advocate and adopt the good expanded heavy property particle shrimp material of water stability.Daily ration, feeding quantity should strictly be controlled, and adjusts flexibly according to weather, water quality, the factors such as shrimp density and actual food ration of carrying, and accomplishes a small amount of many meal, science bait throwing in.Often do not stay residual bait as principle take the inspection bait table in the breeding production.Like this, promote on the one hand the prawn growth, reduce feed coefficient, can alleviate on the other hand the pollution level of water body.
The prawn fine and tender taste is delicious, and in recent years, China market continues to increase the demand of prawn, only depend on to fish for and can not satisfy the demands far away, and only adopt the cultured prawn poor growth of natural bait, and the death rate is high, and it is very necessary therefore substituting the natural bait cultured prawn with mixed feed.Prawn culturing needs in the aquaculture project of high investment, high production, high benefit, and the culture-cycle is long, specification requirement is high, thereby investment risk is large, but its high profit or its deep attraction raiser, along with consumption demand is constantly risen, price rises steadily, and has driven thus the rise of prawn culturing heat.Improving cultivation marine product quality is the key content of current aquaculture.
Spirulina is a kind of common composition of prawn feed, it is a kind of miniature blue-green algae, it not only is easy to gather and preserve, and be of high nutritive value, protein content reaches more than 60%, amino acid forms rationally, and a large amount of unrighted acids, multivitamin and inorganic salts are arranged, and the biochrome with hyperchromic effect, particularly the contained albumen kind of spirulina is vegetable protein, very easily digested and absorb by prawn, the protein sources of making mixed feed with the spirulina prawn of feeding can be improved its growth rate and feed conversion efficiency.
Selenium-enriched food is exactly the food that is rich in trace elements of selenium, generally is divided into ground source selenium selenium-enriched food (claiming again natural selenium-rich food), external source selenium selenium-enriched food (also claiming artificial Organic Selenium food).
Selenium is the trace element of needed by human.Selenium participates in the interior multiple selenoenzyme of synthesized human and contains selenoprotein.Its Glutathione Peroxidase, catalysis hydroperoxides or MDA change water or various alcohols in vivo, eliminate the biomembranous attack of radical pair, and the protection biomembrane is avoided oxidative damage; Selenium participates in consisting of iodate thyroid gland amino acid and takes off the iodine enzyme.Selenium can improve human immunity, promotes the synthetic of Proliferation of lymphocytes and antibody and immunoglobulin (Ig).Selenium has the effect of obvious inhibition and protection to kinds cancers such as colon cancer, cutaneum carcinoma, liver cancer, breast cancer, its mesostate methyl enol in body has stronger active anticancer.The nutrients such as selenium and vitamin E, allicin, linoleic acid, germanium, zinc have collaborative oxidation resistant effect, increase antioxidation activity.Simultaneously, selenium has the effect that alleviates and alleviate heavy metal toxicity.Selenium mainly obtains from diet in the human body, and therefore, the content of Selenium In Foods has directly affected the intake of the daily selenium of people.In the food of natural environment, containing the abundant food of selenium has seafood, mushroom, egg, garlic, ginkgo etc.
Se content in the Effective Raise prawn body can reach the eater and mend selenium, simultaneously the economization cultivation of prawn is had realistic meaning.
In addition, lecithin is added into to have in the animal feed and promotes to grow, promotes calcium phosphorus precipitation, enhancing body resistance against diseases, strengthens the multiple physiological actions such as physical efficiency and endurance, is a kind of good natural feed addictive.If it is added in the prawn feed as main active, can play volume increase, increase effect alive, at present the domestic Related product that there is no.
