Description
Technical field
The present invention relates to lobster cultivation technique field, in particular to a kind of cultural method of lobster volume increase.
Background technique
Freshwater crayfish meat flavour is delicious, full of nutrition, is high protein, low fat and high-energy, nutritious health food,
It is a kind of global edible shrimps, in the important foodstuffs source for just becoming the European people 18th century.China eats freshwater crayfish
History start from the 1960s, as consumer promotes the extensive publicity of the understanding of freshwater crayfish and media, fresh water
Cray food generally enters restaurant, hotel, supermarket and Domestic dining table, and cray demand is very vigorous, due to excessive
Fishing, there is a serious shortage of commercial sized prawn quality is irregular for wild resource；For southwest, the cray source of goods is insufficient, in winter
Substantially without finished product shrimp；And cray aquaculture model majority is the extensive cultivation of ditching formula, rice field is feeding etc. altogether, and per mu yield is not generally high.
Will check on lobster seed, feedstuff feeding, shelling management, regulating and controlling water quality in terms of the cultivation of freshwater lobster, accomplish in real time
Monitoring is caught in due course, and strict control forbidden drug and input cultivate nuisanceless aquatic products, and the economic benefit of lobster is maximum
Change.Cray adaptability is extremely wide, has wider suitable growth temperature, is 10-30 DEG C of Shi Junke normal growth and development in water temperature.
Also can high temperature resistant severe cold, can tolerate 40 DEG C or more of high temperature, can also be safely overwintering in the case where temperature is -14 DEG C of situations below.Gram
The growth of family name crayfish is rapid, at suitable temperature and sufficient bait supply situation, the cultivation through 2 wheat harvesting periods, i.e. attainability
Maturation, and reach commercial sized prawn specification, general hero shrimp growth is faster than female shrimp, and commercial sized prawn specification is also big compared with female shrimp.With many shell-fish
Animal is the same, and the growth of lead and cadnium is also along with shell, when shell, general searching things concealed, as in water plant clump or leaves of plants
Under piece.Weight limit incrementss are up to 95% after shell, can reach sexal maturity for general shell 11 times, and sexal maturity individual can be after
Continuous husking growth.Its service life is not grown, and about 1 year.But in the case where deprivation of food, temperature are lower and more arid, the service life is most
Mostly up to 2-3
The cultural method of some freshwater lobsters is not scientific at present, and freshwater lobster is caused to contain the drugs such as antibiotic, hormone, weight
Metal is exceeded or even helminth and pathogenic bacteria, threatens to the health of people.It is easily sent out in the growth course of cray
The sick black gill, tail, Disease of Zoothamnium, the meat for not only leading to cray and mouthfeel make by strong influence, and greatly
Obtain cray slow growth, the death rate improves；Therefore, a kind of cultivation side of cray that can effectively solve the problem that problem above is invented
Method is current urgent problem to be solved.
Summary of the invention

(2) sterilize: to carrying out in pond plus water, while use topples over bleaching powder and carries out disinfection processing, is then allowed to stand 12-
18h；
(3) fertilizer treatment: adding fertilizer according to the specification of 50kg/100 ㎡, is planting water plant, water with after fertilising 3-4 days
Careless area coverage accounts for the 40-45% of pond area；
(4) lobster is chosen seeds: the larger and healthy posture lobster seedling of selection individual before launching carries out the lobster of seed selection clear
It washes, takes out the impurity adhered to lobster；
(5) it launches: launching and carried out according to the principle of each ten thousand tail of pond 8-10, launch while putting into bait, fit at noon
When feeding soya-bean milk and minced fillet；
(6) it cultivates: feeding feed twice daily, fed every time by 20-30kg/100 ㎡；After one month, 30- is pressed every time
35kg100 ㎡ is fed；After two months, increase feedstuff feeding amount, feeding volume is the 5-6% of shrimp weight.
