Abstract
The invention provides a culture method for making Chinese mitten-handed crabs come into market ahead of time. The method comprises the steps of firstly, determining a pond for the culture of adult Chinese mitten-handed crabs; secondly, in the first ten days of September each year, putting a certain quantity of juvenile crabs in other adult crab culture ponds; thirdly, in January-February of the second year, transplanting water plants in the adult crab culture pond; fourthly, in February-March, putting juvenile crabs obtained from the other adult crab culture ponds into the adult crab culture pond; fifthly, in the last ten days of March, starting to deliver animal bait continuously to the adult crab culture pond; sixthly, in the first ten days of April, putting margaryamelanoides into the culture pond; seventhly, in the first ten days of August, starting to deliver plant bait into the culture pond additionally. Juvenile crabs cultured in the same year are cultured in adult crab culture ponds for nutrient enhancement in advance and animal bait is employed in the whole process of an adult crab culture stage, so that the survival rate and the expansion rate after each moulting can be increased, the gonads can grow quickly and crabs can come into market ahead of time.
Description
Technical field
The present invention relates to a kind of Eriocheir sinensis method is and in particular to a kind of Eriocheir sinensis side of listing in advance
Method.
Background technology
Eriocheir japonica sinensis, are commonly called as crab, steamed crab, are distributed mainly on China's ChangJiang River, Liaohe River water system, the Oujiang River water system three
In big fresh water water system, it is the Important Economic breed variety of China's fresh water fishery.As the treasure in aquatic products, Eriocheir sinensiss because
Delicious flavour, fine and tender taste, the nutritious and deep eating being subject to people, wherein especially most prestigious with ChangJiang River crab.At present,
About 15,000,000 mu of the artificial cultivation area of national Eriocheir sinensiss, about 600,000 tons of annual production, about 50,000,000,000 yuan of annual value of production.Generally feelings
Under condition, the ChangJiang River crab of pond culture started to list successively in annual mid-September, now most of crab because gonad not complete
Entirely ripe and body weight is partially light, apparent availability is less, leads to this period crab market price often to occupy the annual market quotation
High-order.As the Mid-autumn Festival just wherein, then crab is pursued more strongly by market, and the market price also will raise up.Crab now is supported
Growing pattern is usually from the beginning of the annual 1-3 month throws in crab species, sells to harvesting into Eriocheir sinensiss 9-11 month then.And the cultivation of crab species
Journey is from the beginning of annual May throws in megalops larva, sells to harvesting crab species month next year 1-3.Growth cultivates two with becoming Eriocheir sinensiss
Link is relatively independent and formation is effectively connected.Cultivating river crab is farthest made to list in advance, in market price highest period
A large amount of sales, are remarkably improved culture of Chinese mitten crab per mu yield economic benefit.
Content of the invention
For solving the above problems, overcome the shortcomings of in existing Eriocheir sinensis method, the present invention provides a kind of China

The crab species thrown in the pool cultivate gained for the same year in Growth pond, and crab species average size is 140-160/kg, throws in close
Spend for 1000-1200/667m2.
A kind of above-mentioned Eriocheir sinensis list method in advance it is characterised in that the crab species of described input feed bait
Expect the frost wild fisheses for chopping after cooking, day feeding volume is 5.5-6.0kg/667m2, terminate after continuously feeding 60.
A kind of above-mentioned Eriocheir sinensis list method in advance it is characterised in that described transplanting pasture and water species is wheel blade
Black algae and waterweed, plantation ratio is 1: 1, and cultivation spacing is 0.8-1.0m, and plantation coverage rate is 30%-40%.
A kind of above-mentioned Eriocheir sinensis list method in advance it is characterised in that in described one-tenth Eriocheir sinensiss cultivating pool individually
Put the female crab species of Eriocheir sinensiss or male crab species in a suitable place to breed, that is, male and female separately cultivate it is desirable to female crab species or male crab species specification is close, appendage is neat
Entirely, flush, body colour becomes clear, female crab species or male crab species average size be 80-100 only/kg, breeding density be 700-800 only/
667m2.
A kind of above-mentioned Eriocheir sinensis list method in advance it is characterised in that the described animal bait that feeds is
The frost wild fisheses of chopping after cooking, day feeding volume is 0.7-0.8kg/667m2, increase by 1 every 30 day feeding volumes with this radix
Times.
A kind of above-mentioned Eriocheir sinensis list method in advance it is characterised in that described input Bellamya quadrata is thrown in 3 times altogether,
It is respectively, early April, injected volume 130-150kg/667m2, late May, injected volume 40-60kg/667m2, late June, throw in
Amount 80-100kg/667m2.
