Abstract
The present invention relates to a kind of cultural method of cray, comprise the following steps：1) farming site selects；2) farming site is handled；3) pasture and water plantation and culture；4) cray seedling is launched；5) nursing of juvenile prawn；6) into the nursing of shrimp.The present invention passes through the processing to culturing pool, the plantation of algae, training water, and the scientific management of the dispensing of cray seedling, forage feed, the management in later stage etc., benign ecological environment is established, reduces the probability of cray infectious disease, improves the survival rate of cray.The present invention use the feed without bad additive based on supporting, the nutrition equilibrium of each time of cray growth to be effectively ensured, has effectively increased the disease resistance and breeding survival rate of cray, has improved the economic benefit that cray cultivates.
Description
Technical field
The present invention relates to aquaculture, refers in particular to a kind of cultural method of cray.
Background technology
Cray meat flavour is delicious, nutritious, is a kind of high protein, the healthy food of low fat, is that China's fresh water shrimp is supported
The important kind grown, there is the huge market demand, cultivation to benefit the characteristics of high.But cray easily infects disease in developmental process
Disease, while often bite between each other, causing the yield of cray can not effectively improve, while reduce economic effect
Benefit.And during cray is propagated artificially, often there is extensive epizootic disease and the phenomenon of Large Scale Death.And pass
The countermeasure of system is using antibiotic or has the prophylactically addition chemical addition agent progress in the feed for nursing of cray
Processing, commonly using antibiotic and chemicals, it on the one hand result in pathogen and generate the resistance to the action of a drug, prevention effect declines；Separately
On the one hand water quality is have impact on, destroys environment.
Freshwater crayfish is the animal of typical omnivorousness, and it had both eaten green grass, pasture and water, eats grain trough again and animal is raised
Material.The pure natural organic forage feed such as artificial propagation aquatic organism, toy and planting aquatic plants is taken, than the commodity of purchase
Feed palatability is good, nutritious, fresh delicious, can not have to purchase mixed feed completely.Both can avoid because of commercial feed
The oxious components such as hormone are exceeded, ensure commodity lobster green non-pollution, can make the annual feed investment for saving writing again.But
It is that the cray speed of growth that pure natural organic feed is fed is slow, growth cycle length, the serious income for reducing raiser, beats
The enthusiasm of raiser is hit, causes raiser to abandon cultivating cray, and then causes the market price of cray to go up, influences to disappear
The interests of the person of expense.Therefore lobster edibility how is improved, avoids the use of hormone medicine, promote growing for lobster,
It is the problem of current those skilled in the art are studying always.
The content of the invention
The purpose of the present invention is improved and innovated for shortcoming present in background technology and problem, there is provided Yi Zhongke
Learn, the cultural method of the cray of safety.
The present invention comprises the following steps：
1st, farming site selects：Selection has a surface water or underground water makees the region at water source and builds culturing pool, the pH value at water source
In the range of 6-9.5, pond depth 1.2-1.5m, and entery and delivery port is set respectively in bottom of pond both sides, and it is configured with oxygen increasing equipment.
2nd, farming site is handled：Full pond is carried out disinfection processing with lime, be then exposed to the sun two weeks or so and start to train water.
3rd, pasture and water plantation and culture：Waterweed and eel grass, center plant hydrilla verticillata and spray are transplanted in culturing pool surrounding
It is raw；Hydrilla verticillata is planted after should first transplanting waterweed during specific plant, waterweed is transplanted in place in 2-3 months, 3-4 months are wheel
The black algae plant of leaf is in place；After pasture and water are planted, water is maintained at a relatively low level to suppress pasture and water growth, when high temperature arrives
When, lifting water level allows pasture and water to be maintained at below the water surface at 2-5cm all the time；The pasture and water to rot are pulled out in time, by culturing pool
Careless coverage rate control is within 50-60%.
4th, cray seedling is launched：Select and do not launched with the strong cray seedling of pathogen, resistance against diseases into culturing pool,
Every mu is put in a suitable place to breed 6500-7500 tails, and specification is 65-75 tails/jin, and water level control is within 60-90cm, the high temperature depth of water, and water at low temperature is shallow.
5th, the nursing of juvenile prawn：The forage feed juvenile prawn prepared using following raw material, is fed three times daily；Specifically such as
Under：Fish meal 6-20 parts, fermented bean dregs 10-30 parts, corn flour 10-18 parts, sweet potato powder 8-25 parts, dusty yeast 2-5 parts, wheat bran 10-
27 parts, distiller's dried grain 10-15 parts, B B-complex 1-3 parts, peanut powder 1-5 parts, bone meal 2-10 parts, lard 2-5 parts, Radix Isatidis 8-
12 parts, cordate houttuynia 2-5 parts, bighead atractylodes rhizome 3-5 parts, radix glycyrrhizae 2-3 parts, appropriate amount of water, above-mentioned raw materials crush after stir and be made graininess throwing
Hello.
6th, into the nursing of shrimp：Animality is fed using night into shrimp and directly expects and feed daytime that artificial formula feed mode is fed
Support；Wherein animal bait is the trash fish of rubbing, spiral shell freshwater mussel meat, silkworm chrysalis, earthworm, slaughterhouse leftover bits and pieces；Into shrimp man-made feeds by with
The raw material of lower parts by weight is mixed：Corn flour 40-50 parts, rice bran 30-40 parts, soya-bean cake 20-40 parts, chick bone powder 10-15 parts,
Fish meal 5-10 parts, bone meal 5-10 parts, shellfish powder 3-5 parts, starch 1-3 parts, sunflower seed powder 0.3-0.5 parts, shell element 0.05-0.15
Part, asparagus lettuce leaf 3-6 parts, distiller's dried grain 15-20 parts.
7th, phase water quality management is cultivated：Monthly apply quick lime once, every mu of 50kg of dosage；High temperature season changes water in good time, often
Two weeks changes water 1-2 times, changes water 1/4 or so, and in good time oxygenation every time.
In one of the embodiments, the B B-complex in described juvenile prawn feedstuff be vitamin A, vitamin C,
At least three kinds in vitamin B1, vitamin B6, FA, vitamin E, vitamine D3, vitamin K.
The present invention prepare juvenile prawn feed each raw material optimum amount parts by weight be：15 parts of fish meal, 20 parts of fermented bean dregs, corn
15 parts of powder, 15 parts of sweet potato powder, 3 parts of dusty yeast, 18 parts of wheat bran, 12 parts of distiller's dried grain, 2 parts of B B-complex, 3 parts of peanut powder, bone meal 7
Part, 3 parts of lard, 10 parts of Radix Isatidis, 4 parts of cordate houttuynia, 4 parts of the bighead atractylodes rhizome, 2 parts of radix glycyrrhizae, appropriate amount of water.
Each raw material optimum amount parts by weight that the present invention is configured to shrimp feed are：45 parts of corn flour, 35 parts of rice bran, soya-bean cake
30 parts, 12 parts of chick bone powder, 8 parts of fish meal, 8 parts of bone meal, 4 parts of shellfish powder, 2 parts of starch, 0.4 part of sunflower seed powder, shell plain 0.1 part, lettuce
5 parts of bamboo shoot leaf, 18 parts of distiller's dried grain.
Advantages of the present invention and beneficial effect：
The present invention is fed by the processing to culturing pool, the plantation of algae, training water, and the dispensing of cray seedling, feed
The scientific management of foster, the later stage management etc., establishes benign ecological environment, reduces the probability of cray infectious disease, carries
The high survival rate of cray.The present invention use the feed without bad additive as based on foster, cray growth has been effectively ensured
Each time nutrition it is balanced, effectively increase the disease resistance and breeding survival rate of cray, improve cray cultivation
Economic benefit.
