Abstract

A method for culturing fish fries of grass carps with crisp meat comprises the steps of: thoroughly clearing a fish fry pool, drying the pool and discharging water, wherein the water depth is 500-700cm; putting fish fries of the grass carps which are incubated in April in each year into the fish fry pool, wherein the density is 3000-4000 fish fries in each mu; preparing soybeans to be soya-bean milk, and putting the soya-bean milk into the fish fry pool with the putting amount being 1.5-2.5kg/mu for each day, and stopping putting the soya-bean milk after 20-30 days; putting male fish fries, chub fries and carp fries which have the same size into the fish fry pool, wherein the putting density of the male fish fries is 45-60 male fish fries in each mu, the putting density of the chub fries is 40-55 chub fries in ach mu, and the putting density of the carp fries is 3-4 carp fries in each mu; putting duckweeds and cake-shaped rape seed dregs into the fish fry pool, wherein the putting amount of the duckweeds is 30-200kg/mu for each day; the putting amount of the cake-shaped rape seed dregs is 2-10kg/mu for each day; and continuously feeding and stopping feeding in September until the pool is cleared and the trash fish is removed in December. By adopting the method to culture the fish carps of the grass carps with crisp meat to be the grass carps with crisp meat, the meat quality of the grass carps is improved, the content of fiber and protein of the fish meat are increased greatly.

Description

A kind of method that cultivates the crisp grass carp fry

Technical field

The present invention relates to the cultural method of a kind of grass carp, particularly a kind of method that cultivates the crisp grass carp fry.

Background technology

Grass carp also claims " grass carp " (Ctenopharyngodon idellus), and the cultural method of common grass carp is fairly simple, a lot of introductions are arranged in the cultural method of fish, grass carp is simple because of feeding habits, and feed source is extensive, and growth rapidly, output is high, what often be used as pond culture and lake, reservoir, river course mainly puts object in a suitable place to breed, and the flesh of fish of the grass carp that cultivates out is soft, and the flesh of fish of grass carp does not have tender fragility, resistant to cook not, mouthfeel is bad.

Summary of the invention

The purpose of this invention is to provide a kind of method that cultivates the crisp grass carp fry.

The technical scheme that realizes above-mentioned purpose of the present invention is: a kind of method that cultivates the crisp grass carp fry comprises: with the clear end, fry pond, shine the pool, discharge water depth of water 500-700cm; The little grass carp seedling that to just hatch out at the beginning of annual 4 months is put into the fry pond, and density is 3000-4000 bar/mu, soya bean is made soya-bean milk render in the fry pond, and injected volume is 1.5-2.5 kg/acre of day, stops to throw in soya-bean milk after 20-30 days; Put the milter seedling, silver carp seedling, carp fry of equal size in the fry pond, it is 45-60 bar/mu that the milter seedling is thrown in density, it is 40-55 bar/mu that the silver carp seedling is thrown in density, it is 3-4 bar/mu that carp fry is thrown in density, throw in duckweed, cake-shaped rape seed dregs in the fry pond, the duckweed injected volume is 30-200 kg/acre of day, and the cake-shaped rape seed dregs injected volume is 2-10 kg/acre of day, be fed to continuously and stop feeding September, to the clear half congealed trash fish of removing in December.

After will adopting the inventive method cultivation crisp grass carp fry to cultivate into crisp grass carp, the meat of grass carp is improved, and fiber and the protein content of the flesh of fish increase greatly, oppress into tender fragility, and flesh of fish resistant to cook is not mashed, and tasty mouthfeel is tasty and refreshing, becomes colory crisp grass carp.

Below in conjunction with embodiment detailed content of the present invention is further described.
