Abstract
The invention relates to the field of aquaculture and discloses a crayfish shelling period management method. The management method divides the crayfish shelling period into four stages including a shelling interval stage, a shelling earlier stage, a shelling stage and a shelling anaphase stage. According to the different stages, corresponding measures are taken distinctively, which can guarantee success of the crayfish shelling. The acquired crayfish is even in a head and a body, bright and smooth in the shell, big in the body size, strong in vitality, and tight in a commissural inter-space between the crayfish head and the body. According to the management method, production is improved by 35.6%, the death rate is reduced by 27.8%, and economic benefit is increased by 40.2%.
Description
Technical field
The present invention relates to aquaculture field, and in particular to a kind of shell period management method of cray.
Background technology
Cray, also referred to as Procambius clarkii, red crayfish and freshwater crayfish.Likeness in form shrimp and crust is hard.Adult is about 5.6
~ 11.9 centimetres, kermesinus, the nearly black in crust part, belly back side has a wedge-shaped striped.Juvenile prawn body is uniform grey, sometimes
Tool black ripple.Chela is long and narrow.Crust middle part is not separated by areola, substantially has particle on crust.Volume sword has gemmule or volume
Sword end has indentation.It is economic freshwater shrimps, because meat flavour is delicious wide popular to people.Because of its omnivorousness, fast growth, adaptation
Ability forms absolute competitive advantage in local environment by force.Its ingest scope including pasture and water, algae, aquatic insect,
Spoil etc., food is also killed each other when deficient scarce.Cray has become Important Economic breed variety in China in recent years, small
The survival ability of lobster is very strong, and except Asia, Europe And Africa is also its home, therefore becomes world-class cuisines.
In Europe, Africa, Australia, Canada, New Zealand and the U.S., someone eat, and the Louisiana State in the U.S. is known as life
In the world 90% cray has been produced, and locals has just eaten therein seventy percent.Cray " success " worldwide, removes
But the advantage in some forms and habit, must be partly due to its tolerance to pollution environment.It is right in scientific research
Pollutant is very sensitive, or the biology for tolerating very much, is frequently used as environment whether there is the instruction biology being contaminated.Cray because
Build is bigger than other Freshwater shrimps, and meat is also relatively more, because delicious meat, is made into various cookings, including illustrious has
The spicy cray of name（Numb children）Deng, all it is common meal, receive universal welcome.Especially to summer, cray
Supply falls short of demand for yield, and 1 jin of cray just sells for 50-80 units, and profitable opportunity, many aquatic products are cultivated in face of cray
Sight has been surrendered cray cultivation by raiser, however the cray generally existing propagated artificially on Vehicles Collected from Market the bodily form inclined
Small, head body is uneven, and unsound, the problem that crust is hard, gap is big is developed in step, and this is because cray is changing shell period management not
When what is caused, not only cause cray poor quality, the problem that yield declines caused by shell is unsuccessful there is also mutually residual
The phenomenon of food, inducing a series of diseases, therefore strengthen shell period management becomes particularly important.
The content of the invention
In order to solve the problems, such as to there is currently, the invention provides a kind of shell period management method of cray.
The present invention is achieved by the following technical solutions：
A kind of shell period management method of cray, phase, shell early stage, shell phase, shell later stage four between cray shell
In the stage, corresponding measure is taken respectively, comprise the following steps：
（1）The phase between cray shell, by lower water temperature to 27-30 DEG C, the temperature can improve cray physical efficiency eclosion hormone
Content, increase feedstuff feeding amount to original 1.3-1.5 times, largely taking in feeds can help the cray to carry out energy matter
It is that shell carries out sufficient material preparation with the accumulation of trace element, phagostimulant is added in feed, addition accounts for feed ingredient
1-1.5%, the phagostimulant consists of the following composition in parts by weight：TMAO 10-12 parts, dimethyl-β-propionic acid thiophene
Booth 8-10 parts, diallyl disulphide 7-9 parts, ferulic acid 5-7 parts, alanine 4-7 parts, cystine 3-5
Part, glycine 3-5 parts, guanylic acid 2-4 parts, inosinicacid 2.5-3.5 parts, the phagostimulant improves the palatability of feed, makes small dragon
Shrimp food ration increases, and has significant food calling and growth-promoting effect, and substantially reduce the time of ingesting so that the shell time tends to
Unanimously；
（2）In cray shell early stage, shell phase, by lower water temperature to 25-28 DEG C, the alternating temperature of certain amplitude plays early warning work
With, cray shell speed can be accelerated, after cray stops ingesting, feed is no longer fed, inject new water, the small dragon of shell phase
Shrimp needs to draw substantial amounts of water, keeps water quality totally to prevent cray bacteria infection, is delivered in water body and promotees shell agent, should
Promote shell agent to be made up of following raw material in parts by weight：Windproof 12-15 parts, radix cyathulae 11-14 parts, rhizome of chuanxiong 11-13 parts, great Sha
Leaf 10-13 parts, selfheal 9-13 parts, 9-12 parts of toad grass, daghestan sweetclover herb 9-11 parts, bitter 8-11 parts of the courage in ground, tuber of pinellia 7-9 parts, promote to slough off
Contain substantial amounts of phytosterol class compound in shell agent, shell can be accelerated and promote growth, and shell synchronism substantially to increase,
And to pasture and water are increased in pond, light is both reduced, and the environment of comfortable safety is created for cray, pasture and water coverage rate reaches
70-80%, keeps quiet around waters, prevents from leading shell due to scaring unsuccessful；
（3）In the cray shell later stage, water temperature is gradually reverted into normal temperature, remove water surface floating grass, increase light application time, extended to
10-12 hours, promote growing for new shell, beginning feeds feed on a small quantity, after cray is from the latent upper water surface of bottom of pond, enough throwings
Feeding material, supplements in feed and largely contains calcium component, makes the seam crossing tighter gap of shrimp head and trunk.
Further described as to such scheme, the rush shell agent preparation method is：
（1）The raw material of above-mentioned weight portion is crushed to 80-100 purposes powdered, is put into after mixing in extractor, add 500-
600 times of water of volume, soak 12-15 hours, every stirring in 1 hour once；
（2）Soak is heated to 100 DEG C, is extracted 10 hours, filtrate is collected by filtration, the remaining dregs of a decoction are added into 400-500
Extracted 12 hours at 120 DEG C of the water of times volume, filtrate is collected by filtration；
（3）The filtrate for obtaining will twice be collected to merge, the 40-50% that original volume is concentrated under reduced pressure at 50-60 DEG C is obtained final product.
Further described as to such scheme, the rush shell agent usage amount is that every cubic metre of waters is blended into 20-25
Milliliter.
Beneficial effects of the present invention：The present invention by the cray shell cycle be divided between shell the phase, shell early stage, the shell phase,
Shell later stage four-stage, takes corresponding measure for different phase respectively, it is ensured that cray shell success, the cray for obtaining
Head body is uniform, shell is bright and slide, build is big, energetic, the seam crossing tighter gap of shrimp head and trunk, by output increased
35.6%, the death rate reduces 27.8%, increased 40.2% economic well-being of workers and staff.
