Description
Technical field:
The invention belongs to lobster cultivation technique field, particularly to a kind of nuisanceless freshwater lobster
Cultural method.
Background technology:
Freshwater lobster, is commonly called as cray, belongs to Arthropoda first gram guiding principle Decapoda Palinuridae,
Head and chest are thicker, and shell is hard, delicious meat, are that a kind of low fat low cholesterol is high
The nutrient tonification food of albumen.Freshwater lobster is relatively big except having build, outside meat is fertile, also has
Growth cycle is short, and yield is high, eats miscellaneous adaptable feature, is particularly suitable for artificial commodity and supports
Grow.
The cultivation of freshwater lobster it is noted that some: bottom fish can not be supported by too much set, and put lobster
Need to remove trash fish before seedling and when lobster cultivates, prevent lobster from being eaten；Should not carry out high density,
Low throwing seedling, the lobster cultivation of low receipts stubble, can reduce build and the yield of lobster, increase and cultivate into
This；The seedling of lobster should not select the lobster of natural propagation in Chai Tang, reed ditch, and should not be with supporting
Fish pond culture lobster, can affect lobster build and yield and waste water resource, be not likely to produce through
Ji benefit.
The at present cultural method not science of some freshwater lobster, cause freshwater lobster contain antibiotic,
The medicines such as hormone, heavy metals exceeding standard, even parasite and pathogenic bacteria, healthy to people
Threaten.Because of lobster seed to be checked on, feedstuff feeding, de-in terms of the cultivation of freshwater lobster
Package reason, regulating and controlling water quality, accomplish to monitor in real time, fish in good time, strict control forbidden drug and
Input, cultivates nuisanceless aquatic products, by the maximization of economic benefit of lobster.
Summary of the invention:
It is an object of the invention to provide the cultural method of a kind of nuisanceless freshwater lobster, this cultivation side
Method is provided for a long term, by algae, the nutriment of sustained release and small-sized veil, the growth that lobster is excellent
Environment, periodically throws in microorganism reagent and vitamin combination, and during for the different growth of lobster
Phase throws something and feeds, it is ensured that on the basis of lobster health is non-harmful, promotes lobster fast-growth, carries
The yield of high lobster.
The purpose of the present invention is achieved through the following technical solutions:
The cultural method of a kind of nuisanceless freshwater lobster, comprises the following steps:
(1) select to have abundant water resources, sludgeless pond, the deep 1-1.5m in pond, upper in pond
Face arranges roof insulating, and surrounding arranges the escaping-preventing facilities that 0.5m is high, offers 3-4 and enter in pond
Delivery port, intake-outlet arranges the screen pack of 30-50 mesh, the water being allowed to dry in pond, removes dragon
The natural enemy of shrimp is biological, and Exposure to Sunlight 3-5 days obtains vacant pond；
(2) in the vacant pond that step (1) obtains, the deep water of 0.5-1m is put into, sterilization
Rear plantation pasture and water, throw in the nutriment of sustained release, place small-sized veil, the water in regulation pond
Temperature, dissolved oxygen amount and pH value, obtain cultivating pond；
(3) the shrimp seedling selecting a length of 0.8-1cm renders to cultivation pond prepared by step (2)
In the pool, carry out feedstuff feeding, first week to the 3rd week, throw something and feed every day 2 times, throw something and feed well-done
Soya bean, the pellet of yolk, feeding volume is the 10-12% of lobster body weight, 4th week to
Seven weeks, soya-bean cake of throwing something and feeding, wheat, corn, microorganism formulation and vitamin combination, feeding volume was
The 8-10% of lobster body weight, after the 8th week, cordate houttuynia of throwing something and feeding, scutellaria and Radix Glycyrrhizae are as medium-height grass
Medicine plant feed, then pumpkin of throwing something and feeding, algae, earthworm and planktonic organism, feeding volume is lobster body
The 8-10% of weight, in period of throwing something and feeding, carries out improving water quality, adds water for every 3-5 days, filter sterilization
Oxygenation, regulation water temperature, dissolved oxygen amount and pH value, and throw in Young grass carp and spiral shell.
Preferred as technique scheme, the pasture and water described in step (2) are reed, water hyacinth
Or waterweed, the area coverage of pasture and water accounts for the 30-40% of pond area.
Preferred as technique scheme, the nutriment of the sustained release described in step (2) is recessed
Soil rod soil, hydroxyapatite and the mixture of fermentation fertilizer, weight ratio is 3:2:1.
Preferred as technique scheme, the pond described in step (2) or step (3)
Water temperature be 15-25 DEG C, dissolved oxygen amount is 6-8mg/L, and pH value is 6.5-7.5.
Preferred as technique scheme, the shrimp seedling injected volume described in step (3) is 20,000-2.5
Ten thousand tails/mu.
Preferred as technique scheme, the microorganism formulation described in step (3) is EM bacterium
And bacillus, vitamin is combined as Cobastab and vitamin D, microorganism formulation and Wei Sheng
The input amount of element combination is 30-50kg/ mu.
The beneficial effects of the present invention is: this cultural method, by reasonably planting pasture and water, is placed
Slow-release nutrient material and small-sized veil, feed a small amount of Young grass carp and screw in pond,
The diversification of lobster living environment can be ensured for a long time, promote quality and the yield of lobster, be also beneficial to
Increase water quality.When throwing something and feeding of lobster, feeds according to the different growing stage of lobster, and fixed
Phase supplements microorganism formulation and vitamin combination, it is ensured that the nutrition needed for lobster growth, improves dragon
The nutritive value of shrimp, obtains non-harmful freshwater lobster.
