Abstract
The invention discloses a green aquaculture method. The method comprises the steps of building a pond; injecting water; releasing young aquatic animals; feeding the young aquatic animals with feed; and treating a water body. A microorganism water purification agent is adopted in the step of treating the water body and comprises the following raw materials in parts by weight: 8-12 parts of rhodococcus erythropolis, 8-12 parts of bacillus subtilis, 3-7 parts of nitrococcus, 3-7 parts of thiobacillus denitrificans, 3-7 parts of synechococcus, 15-25 parts of sepiolite, 55-65 parts of bentonite, 15-25 parts of potassium feldspar, 20-40 parts of an organic flocculant and 10-20 parts of a culture medium. According to the green aquaculture method, pollutants disappear or are reduced under the combined effect of microorganisms, an adsorbent and the flocculant, water resources are saved, the cost is low, the water body purification effect is good, the aquatic product growth speed is high, few diseases are caused, and the aquatic product yield is high.
Description
Technical field
The present invention relates to the raising method of a kind of aquatic animal in aquaculture field, be specifically related to a kind of aquatic green cultural method.
Background technology
Since 20 century 70s, world aquaculture increase of production is rapid, and the proportion in aquatic products industry also improves day by day.Aquaculture CHINESE FRESHWATER cultivation history can trace back to B.C. 11st century.B.C. 5th century, existing " breed fish through " came out.Freshwater aquiculture mainly contains two types: one is pond fish farming cyprinid fish, obtains high yield with bait throwing in, fertilising, and is raised together with by the fish of various different feeding habits, to give full play to water body productivity.Another type puts seed in a suitable place to breed in the large and medium-sized waters such as lake, reservoir, stream, paddy field, and the main natural bait that relies on obtains aquatic products.National freshwater aquiculture area about 4,600 ten thousand mu (account for and can support 61% of area) in 1986, wherein pond accounts for 35%, concentrates on the middle and lower reach of Yangtze River and the Delta of the Pearl River; Lake accounts for 17%, mainly in lower Yangtze and northeast, Inner Mongolia; Reservoir accounts for 37%, the distribution whole nation; Stream accounts for 9%, mainly in Jiangsu, dense waterway net region, Zhejiang.Freshwater aquiculture gross yield occupies first place in the world for many years always, recently annual with about 22% speed increase, 1986 annual productions are 2,950,000 tons, account for 36% of national aquatic products gross yield.Wherein pond accounts for 74%, and reservoir accounts for 8%, and all the other are the output of lake, stream and paddy field.
CHINESE FRESHWATER cultivation object, except traditional cyprinid fish, also add non-crucian carp, rainbow trout, silverside, white crucian carp, Macrobrachium rosenbergii, Eriocheir sinensia, Anodonta etc. in recent years.The employing of artificial propagation techniques and raising in cage method, for cultivation provides a large amount of seed.
The mariculture of China also has history more of a specified duration, and the Song dynasty has artificial culture pearl, inserts the record that bamboo supports oyster and algal culture.Within 1986, carry out the shallow sea of mariculture, beach area be 4,880,000 mu (account for can for 24% of cultured area 2,000 ten thousand mu), output is 85.8 ten thousand tons, accounts for 10% of national aquatic products gross yield.Wherein sea-tangle accounts for 23.7%, and laver accounts for 1.6%, and mussel accounts for 24.5%, and oyster accounts for 6.4%, and razor clam and blood clam account for 17.5%.Cultivate mullet, dace, perch, milk fish, prawn, sea water pearls, Bao, scallop, sea cucumber etc. in addition.
Along with the growth of cultivated animals, in pond, relative density increases, and the residual bait of water body, excreta, pasture and water Lao Ye rot, and can consume a large amount of oxygen, can produce the toxic gases such as hydrogen sulphide again, ammonia nitrogen accumulation increases, and pH value declines, and very easily causes the general pond of floating head.Conventional method mainly changes water in time, on a small quantity repeatedly; The present invention, according to the development of existing water technology, in conjunction with the feature of aquaculture water, has invented a kind of method adopting microbial water-purifying agent to carry out aquaculture.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is to provide a kind of aquatic green cultural method.
For achieving the above object, the technology used in the present invention solution is:
A kind of aquatic green cultural method, comprise build the pool, water filling, put seedling, feed of throwing something and feeding, water body treatment step, described water body treatment step adopts microbial water-purifying agent.
Described microbial water-purifying agent is made up of following weight parts raw material: rhodococcus erythropolis (Rhodocodduserythropolis) 8-12 part, bacillus subtilis (Bacillussubtilis) 8-12 part, Nitrosococcus (Nitrosococcus) 3-7 part, thiobacillus denitrificans (Thiobacillusdenitrificans) 3-7 part, Synechococcus (Synechococcus) 3-7 part, sepiolite 15-25 part, bentonite 55-65 part, potassium feldspar 15-25 part, organic flocculant 20-40 part, medium 10-20 part.
Described organic flocculant is made up of polyacrylamide, Sodium Polyacrylate, polydiallyldimethyl ammonium chloride, and the mass ratio of described polyacrylamide, Sodium Polyacrylate, polydiallyldimethyl ammonium chloride is (1-3): (1-3): (1-3).
Described medium is prepared from by following materials by weight percentage: glucose 0.6-1.2wt%, dipotassium hydrogen phosphate 0.15-0.25wt%, potassium dihydrogen phosphate 0.15-0.25wt%, sodium chloride 0.005-0.015wt%, calcium chloride 0.005-0.015wt%, ammonium sulfate 0.01-0.03wt%, urea 0.03-0.07wt%, yeast extract 0.03-0.07wt%, magnesium sulfate 0.005-0.015wt%, surplus is water.PH7.2,120 DEG C of sterilizing 30min, adopt industry universal method formulated.
Present invention also offers the preparation method of mentioned microorganism water purification agent: adopt conventional method to be inoculated in medium rhodococcus erythropolis, bacillus subtilis, Nitrosococcus, thiobacillus denitrificans, Synechococcus, then sepiolite, bentonite, potassium feldspar is added, finally add organic flocculant to mix, obtain microbial water-purifying agent.
