Abstract
The invention relates to an intensified breeding and fattening technique for Chinese mitten-handed crabs, relating to aquaculture technologies. The intensified breeding and fattening technique for the Chinese mitten-handed crabs is characterized by comprising the following steps of: selecting adult Chinese mitten-handed crabs after the final reproduction exuviation as breeding and fattening objects, separating the male crabs and the female crabs, and respectively putting the male crabs and the female crabs into fattening pools; and feeding the crabs twice every day (in the morning and at night), by a mixture of concentrated vegetable feed and animal bait after the Chinese mitten-handed crabs are in a fattening stage, mainly a weight gaining stage, wherein the daily feeding amount is generally 3-4% of the weight of the Chinese mitten-handed crabs. The Chinese mitten-handed crabs after the intensified breeding by the method disclosed by the invention has plentiful grease and meat, thereby having enough energy to pass through a winter stage until April or May of the next year; therefore, by utilizing intensified manners and corresponding matched techniques, the time to market of the Chinese mitten-handed crabs can be largely prolonged, the balance marketing of the Chinese mitten-handed crabs can be realized basically, and the Chinese mitten-handed crabs with plentiful grease and meat and delicious taste can be obtained; and in addition, the quality of the Chinese mitten-handed crabs in the market is improved, and the higher benefit can be obtained at short time.
Description
Technical field
The present invention relates to aquaculture technology, reinforced cultivating and the fattening technology of concrete Chinese suede huge legendary turtle crab.
Background technology
Fattening of Eriocheir sinensia, in fact be exactly to obtain the plentiful Eriocheir sinensia of cream fat, and whether Eriocheir sinensia cream fat is plentiful, shows on the richness of the nutrition (lipid storage) of hepatopancrease and sexual gland (cream), and its most direct index is the good and bad of gonad development.Because gonad development is good, must rely on hepatopancrease and constantly obtain abundant nutrition and do guarantee, so mainly summing up in the point that, the aim of fattening make Eriocheir sinensia obtain good sexual gland of growing.And this part work is is also nourished and generated just and is learned the main field of research, mainly is the relation of research parent culture and breeding.This respect studies show that in a large number that both at home and abroad parent's nutrition condition has great influence to its reproductive performance and seed quality, by the parent is carried out rational reinforced cultivating, can significantly improve its reproductive performance and seed quality.
A key issue that exists at present during China Eriocheir sinensia is cultured is exactly the work of fattening of ignoring Eriocheir sinensia aborning, and this often causes the coefficient of condition that goes on the market into crab not enough, and cream fat is not plentiful, greatly the quality and benefits of influence listing.Ignoring the work of fattening of Eriocheir sinensia simultaneously, also is to cause the inferior principal element of listing crab.How to use so the aim of fattening is mainly summed up in the point that at last, make Eriocheir sinensia obtain good sexual gland of growing by fattening technology.And this part work is is also nourished and generated just and is learned the main contents of research, so research that attention is nourished and generated and learned, to promoting and improve the fattening technology of Eriocheir sinensia, it is very important and necessary that economic benefit of increase Eriocheir sinensia and peasant culture income, this be because, after Eriocheir sinensia reproduction shell is in the end finished, also Eriocheir sinensia begins breeding migration just, in the time of coastal migration, and also Eriocheir sinensia best opportunity of fishing for just this moment, this time is generally before and after National Day.So,, a large amount of Eriocheir sinensia listings are arranged in this stage.Because dog-eat-dog, price comparison is low.Also has a main cause, at this moment Shang Shi crab, because reproduction shell just, nutriment is not accumulation also, the crab specification is big, but coefficient of condition is low, and common saying claims " ghost crab ", and nutritive value is not high, so to these crabs reinforced cultivating and fattening before listing, can not only avoid price competition, and can improve the listing quality of crab, obtain high benefit at short notice.
Summary of the invention
The present invention needs the technical solution problem to provide that a kind of can to obtain cream fat plentiful, and muscle is full, reinforced cultivating and the fattening technology of the Chinese suede huge legendary turtle crab of delicious flavour.
Reinforced cultivating and the fattening technology of China suede huge legendary turtle crab, it is characterized in that: select the Chinese suede huge legendary turtle crab of last reproduction shell to become crab as cultivating and fatten object, male and female are separated, put into respectively and fatten the pond, after suede huge legendary turtle crab enters fattening period, be mainly the short fat weightening finish stage, combine with vegetalitas concentrated feed and animal bait, sooner or later respectively throw something and feed once, day feeding volume generally accounts for the 3-4% of suede huge legendary turtle crab body weight;
Male Chinese suede huge legendary turtle crab mainly is to allow its long crab cream, the feed of its nursing is that main major part is an animal protein with animal bait mainly, the Chinese suede huge legendary turtle crab of female crab mainly is to allow its long crab oil, and that just selects the prescription feed of long crab oil, mainly based on the vegetalitas concentrated feed.
Beneficial effect of the present invention: the present invention is by the Eriocheir sinensia of reinforced cultivating, its male and female are separately raised, can make its cream fat plentiful, muscle is full, there are enough energy to make and fatten Eriocheir sinensia by the stage of surviving the winter, up to the 4-5 month in next year, like this by enhancements and corresponding supporting technology, can prolong the Time To Market of Eriocheir sinensia greatly, substantially accomplish the equilibrium listing of Eriocheir sinensia, and it is plentiful to obtain cream fat, and muscle is full, the Eriocheir sinensia of delicious flavour, improve the listing quality of Eriocheir sinensia, obtain high benefit at short notice, another one very chief reason is that male and female have separately been avoided Eriocheir mating in fresh water, because Eriocheir mating in the fresh water of preference temperature is easy to death.
