" bamboo shoot shell fish " one comes from Thailand, the bamboo shoot shell fish be named because external form exactly likes bamboo shoots, its delicious meat, and in China, cultured output is less, belongs to unexpected winner cultivation fingerling." bamboo shoot shell fish " import price is always very steady, and the 80s and 90s in last century is about per kilogram 140 ~ 160 yuan to port valency, and be also stabilized in per kilogram 120 yuan in recent years, demand increases year by year." bamboo shoot shell fish " not yet forms large-scale cultivation in the original producton location such as Southeast Asia, Australia, has over halfly to derive from wild adopting and catch in its exported product.Current, the bamboo shoot shell fish large-scale cultivation technology of the country of origin and China are in same level substantially.Concerning China, " bamboo shoot shell fish " demand exceeds supply, is because bamboo shoot shell fish one is that the culture-cycle is long, and area, Pearl River Delta generally needs within 20 months, just to form marketable fish and sells; Two is that survival rate is low, only has about 10% from seed to the survival rate of marketable fish; Three is live fish bait complex operations of throwing something and feeding; Four is that cost is high, and cultivation has a big risk.

Summary of the invention

The present invention is directed to above-mentioned defect, a kind of cultural method of hybridizing bamboo shoot shell fish is provided, chilled bait of directly ingesting can be cultivated, neat specification, the hybridization bamboo shoot shell fish fingerling that survival rate is high, improves survival rate and the growth rate of bamboo shoot shell fish culture, reduce aquaculture cost, efficient increasing cultivates income and benefit.

Technical scheme of the present invention is as follows:

The cultural method of hybridization bamboo shoot shell fish, the step comprised has: parent population hatches breeding, determines to hybridize bamboo shoot shell fish bait, adjustment and optimization bait scheme, gradually reduce the consumption of bait in chilled bait, until tame out the hybridization bamboo shoot shell fingerling of chilled bait of directly ingesting, chilled bait is finally adopted to cultivate completely.

Further, described parent population hatching breeding, adopts the bamboo shoot shell fish body hatching of high-quality Thailand to breed out hybridization bamboo shoot shell fish seedling.

Further, describedly determine hybridization bamboo shoot shell fish bait, according to the biological property of hybridization bamboo shoot shell fish, design the bait of 3 kinds of hybridization bamboo shoot shell fishes, then carry out at three seedling breeding pools test of throwing something and feeding, measurement, screening, comparison 3 kinds of bait effects, determine the tentative programme of hybridizing bamboo shoot shell fish bait.

Further, described adjustment and optimization bait scheme the bait determined are applied to pond culture test, according to result of the test adjustment and optimization bait scheme.

Further, described domestication is in cultivation, gradually reduce the consumption of bait in chilled bait, until tame out the hybridization bamboo shoot shell fingerling of chilled bait of directly ingesting.To improve survival rate and the growth rate of bamboo shoot shell fish adult fish culture, reduce aquaculture cost, control marketable fish quality safety, increase culture benefit, promote the industry development of hybridization bamboo shoot shell fish culture.

Further, described adopt completely chilled bait cultivate be by domestication after hybridization bamboo shoot shell fingerling drop into fish pond, chilled bait of directly throwing something and feeding cultivates.

Further, described bait is mainly through artificial allotment, and employing small fish is main material, and being equipped with a small amount of analysis for soybean powder is auxiliary material.

Further, described hybridization bamboo shoot shell fish culture in the winter time time need build roof insulating and be incubated to fry, prevent bamboo shoot shell fish dead because of the uncomfortable machine of low temperature.Described roof insulating mainly adopts the roof insulating building the thin covering canopy of film and the covering of other forage.

Further, in the cultural method of described hybridization bamboo shoot shell fish, parent population hatching reproductive number controls more than 30,000 tails.

Further, seedling breeding pool three in the cultural method of described hybridization bamboo shoot shell fish bait, its specification is 4 meters × 5 meters × 0.8 meter, is equipped with oxygen increasing equipment, enters draining conveniently.

The present invention shows following advantage in practice:

1, improve survival rate and the growth rate of bamboo shoot shell fish culture, reduce aquaculture cost, increase cultivation income and benefit.

2, by using bait in fry rearing process, the eating habit of domestication hybridization bamboo shoot shell fish, cultivates chilled bait of directly ingesting, neat specification, the hybridization bamboo shoot shell fish fingerling that survival rate is high.

3, Optimal culture method, Shortening culturing period to 16 month, breeding process only need take a winter canopy, reduces cultivation risk, general raiser is easily operated, and for hybridization bamboo shoot shell fish industrialization cultivation creates conditions, drives the development in chilled market simultaneously.

Embodiment

Below in conjunction with embodiment, technical scheme implementation step of the present invention is described in further detail.

1) by parent population hatching breeding, breed out the long hybridization bamboo shoot shell fry for 3cm of body, quantity controls more than 30,000 tails.

2) the hybridization bamboo shoot shell fry of the long 3cm of 30,000 urosome is put into 3 seedling breeding pools respectively, culture experiment is carried out in density 10,000 tails/pond, and seedling breeding pool is 4 meters of X5 rice X0.8 rice, is equipped with oxygen increasing equipment, enters draining conveniently.To throw something and feed enter seedling breeding pool second day the bait of this project autogamy and chilled from bamboo shoot shell fry.This experimental program is furnished with A, B, C tri-kinds of baits, respectively corresponding fixing input 1#, 2#, 3# tri-seedling breeding pools.After throwing something and feeding 20 days, difference sampling measurement fish body weight, body are long, according to measurement result, bait minimum for individual growth difference are tentatively defined as the bait continuing experiment.
