Description
Technical field：
The invention belongs to aquaculture field, is related to a kind of cultural method of fish, and in particular to " profit occasion fish " scientific culture method.
Background technology：
Grass carp is popular freshwater fish products, is the cheap animal protein sources of important high-quality in our people's day meals, and the annual yield in the whole nation, at more than 400 ten thousand tons, is one of important cultured freshwater fish of China.Used as the main herbivorous fishes kind that China raises, the feeding habits of grass carp begin to convert to phytophage in the long 2.6cm of body, and pasture and water, herbage are the natural foods of grass carp eating, and the main bait source of conventional husbandry grass carp.
In recent years, with the development of feed industry, mixed feed plays protein content height, fast growth in the cultivation of grass carp, saves the artificial, effect of high financial profit.But, high protein is fed in a large number, high-energy bait, makes grass carp passively change feeding habits, and cannot adapt to the change of feeding habits when function is another in vivo, ingested more than the bait of its nutritional need for a long time, nutrition can not be converted completely, and body fat accumulation is excessive, causes grass carp the bad symptom of Nutrition and Metabolism occur, cause grass carp immunity and premunition decline, there is also such as flesh quality decline, taste bad the problems such as.
For the high problem of the grass carp incidence of disease, most common way feeds the various feed addictives containing chemicalses such as antibiotic, not only water quality is had an impact, and can be in grass carp cylinder accumulation antibiotic, and causing drug-fast generation, these antibiotic can enter human body as people eat various fish products, and this just result in the abuse of antibiotic indirectly, it is possible to cause multiple drug induced diseases, while feed addictive can also reduce the quality of grass carp.As growth in the living standard, people are put forward higher requirement to the quality of cultured fishes, grass carp quality is low, poor taste the problems such as urgently to be resolved hurrily.
Content of the invention
It is an object of the invention to provide " profit occasion fish " scientific culture method.On the premise of the culture efficiencies such as the growth period for not changing grass carp, mix the mode of feeding using green grass with mixed feed, significantly improve the quality of grass carp, technology is simple, cost of investment is low, risk is little, strong operability, is easily mastered application, it is easy to penetration and promotion.
The technical scheme is that：
" profit occasion fish " scientific culture method, it is characterised in that in breeding process, carries out mixing using mixed feed collocation green grass and feeds.
The mixed feed and green grass ratio are 1: 1-1: 2 (dry ratios).
Preferably, before grass carp listing 1-2 month, mixes in mixed feed and raises the self-control Chinese herbal and crude drugs preparations for feeding 0.5-2%, and the self-control Chinese herbal and crude drugs preparations includes that allicin, Radix Isatidis, the Radix Astragali, Radix Glycyrrhizae, honeysuckle, bark of eucommia fleece-flower root dissipate.
In the self-control Chinese herbal and crude drugs preparations, each component content is respectively：Allicin 25-45%, Radix Isatidis 5-20%, Radix Astragali 5-20%, Radix Glycyrrhizae 5-15%, honeysuckle 5-15%, bark of eucommia 5-15%, Shouwu San 5-15%.
Preferably, in the self-control Chinese herbal and crude drugs preparations, each component content is respectively：Allicin 30%, Radix Isatidis 15%, the Radix Astragali 15%, Radix Glycyrrhizae 10%, honeysuckle 10%, the bark of eucommia 10%, Shouwu San 10%.
Preferably, the green grass is preferably hybrid giant napier or napier grass.
Preferably, in breeding process, the pH value of water quality is controlled in 7-8.5, transparency 30-40cm, solubility are maintained at more than 5mg/L.
In breeding process, feed 4 days per continuous, stop eating 2-3 days.
The present invention " profit occasion fish " scientific culture method has following features and beneficial effect：
(1) according to the growth characteristic of grass carp, in conjunction with prior art, the present invention is using green grass collocation mixed feed feeding grass carp, mixed feed can promote the speed of growth of grass carp, meet its demand to protein, feeding green grass meets the habit of grass carp, and containing the multivitamin required for grass carp healthy growth in green grass, on the premise of the Growth of Grass Carps Ctenopharyngodon Idellus phase is not changed, the profile and interior quality of grass carp are significantly improved.
(2) allicin is a kind of natural antibacterial material, the growth of pathogenic bacteria in grass carp body can effectively be suppressed, to grass carp because the various bacteriosises such as the rotten cheek for causing, red skin, enteritis, bleeding and its complication of infecting have significant curative effect, there is and effect similar with antibiotic, but the side effect such as medicine is residual of antibiotic-free.Additionally, after allicin is by grass carp intake in vivo, effectively can adjust and the formation for stimulating the amino acid for producing fragrance in fish body, meat is more delicious after the cooking to make grass carp, and local flavor is unique.The self-control Chinese herbal and crude drugs preparations is a kind of complex Chinese herbal medicine, wherein each component collective effect, rate of body weight gain can be improved, strengthen protein, dry, the digestibility of fat, the content of necessary amino acid in crude protein is improved, is promoted grasscarp liver and muscle transaminase, the effect of alkaline phosphatase activities, and then is improved generation and the quality of grass carp, there is certain disease-resistant bactericidal action also simultaneously, the usage amount of antibiotic can be greatly reduced.
(3) green grass described in also includes the dark green plant rich in cellulose such as various discarded vegetable leafs, tendril leaf of potato class in addition to floods and droughts grass class; source is widely; and low price, bioavailability are high, the excreta such as nitrogen, phosphorus is low, is conducive to environmental protection.The self-control Chinese herbal and crude drugs preparations is conventional Chinese herbal medicine, is readily available.
In addition, the water body environment for building suitable Growth of Grass Carps Ctenopharyngodon Idellus is also to produce one of essential condition of high-quality grass carp.And suitably stopping eating to increase the amount of exercise during food of seeking of fish, amount of exercise increase is consumed can internal fat, while muscle cell diminishes, the protein density increase of meat fiber, so that the meat of grass carp is closely, taste can improve.
Specific embodiment：
With reference to specific embodiment, the invention will be further described, but the included scope not limited to this of the present invention.
Embodiment 1
Nanhai District Foshan City plant selects 1000 tail of grass carp of more than 0.5 kilogram of healthy, neat specification, stochastic averagina to be divided into 2 groups, moves into and is cultivated in pond.Group 1 is traditionally cultivated, and all feeds mixed feed；Group 2 feeds hybrid giant napier and mixed feed mixing feeds, and ratio is 1: 1 (dry ratio), feeds 4 days per continuous, stops eating 3 days.45 days before grass carp listing, mix in mixed feed and raise the self-control Chinese herbal and crude drugs preparations for feeding 1%, and its component is as follows：Allicin 30%, Radix Isatidis 15%, the Radix Astragali 15%, Radix Glycyrrhizae 10%, honeysuckle 10%, the bark of eucommia 10%, Shouwu San 10%.In breeding process, the water pH value in pond is controlled in 7-8.5, transparency 30-40cm, solubility are maintained at more than 5mg/L.When results to the end of the year, compare with group 1, the grass carp for organizing 2 either still has different degrees of improvement, price to be also higher by 20-30% than like product in body colour in terms of nutritive composition in muscle, its outward appearance and interior quality evaluation are as follows：
1st, outward appearance：
, from observing in appearance, 1 build fertilizer of group is short for two groups of test fish, and body colour is substantially partially white, and fish scale pigment accumulation is few；Group 2 builds relatively tall and thin, body colour is deeper, and fish scale pigment accumulation is more, fish body table be in shallow blackish green gloss, concrete biological indicator such as table 1.
The contrast of 1 different disposal grass carp biological property of table.
