Abstract

A grisped grass carp culture method comprises the following steps: treating the bottom and water of a fishpond; preparing a synthetic feed; and feeding the grass carps in a throwing manner. The synthetic feed is obtained by mixing, drying and granulating bone meal, shell powder, broad bean, corn, wheat, lotus seed, sophora flavescens, rough fish, carrot and mashed garlic.

Description

Method for cultivating crisp grass carp

Technical field

What the present invention relates to is method for cultivation of fish, particularly the grass carp cultural method.

Background technology

Grass carp, also claim " grass carp " (Ctenopharyngodon idellus), the cultural method of common grass carp is fairly simple, a lot of introductions are arranged in the cultural method of fish, and grass carp is simple because of feeding habits, and feed source is extensive, and growth rapidly, the output height, 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 of culturing out is soft.

Summary of the invention

The purpose of this invention is to provide a kind of method for cultivating crisp grass carp, promptly make the meat of grass carp obtain improvement by cultural method, make and oppress into tender fragility, and oppress anti-cannot not boiling mashedly, tasty mouthfeel is tasty and refreshing.

The cultural method of crisp grass carp of the present invention comprises:

Processing at the bottom of A, the crawl;

Plough deeply 50-70cm at the bottom of the pond with crawl, shone in the sun 7-10 days, do drug disinfection then and handle, at the bottom of the smooth pond, at the bottom of the pond, spread the thin quicklime of one deck, and then at the thick river sand of Chi Dipu one deck 10-25cm;

B, pond water treatment;

Cultivate natural algae at the water surface in fishpond 40-50%, it not only can purify water, and also can be fish simultaneously natural green fodder is provided, and strengthen the antibody ability of fish;

C, water quality, the depth of water require and handle;

Water quality is controlled between the pH5-6.5, improvement is necessary to flesh of fish meat for this, the depth of water will be not less than 70-80cm when fry was thrown in, added water once every 3-5 days then, add water 10-15cm at every turn,, add the degree of depth of big flood with growing up of fish, make the depth of water reach 1300-1800cm, and take float to advance, repeatedly change the way regulation and control water quality of water for a short time;

D, put in a suitable place to breed, the grass carp of equivalent weight size is mixed with a spot of crucian, silver carp, carp put in a suitable place to breed, mix about proportioning of putting and be;

Grass carp 1000 tails

Crucian 150-330 tails

Silver carp 15-50 tails

Carp 5-15 tails

E, synthetic diet preparation weight ratio;

(1), broad bean 40-55

(2), trash fish 15-25

(3), carrot 8-12

(4), corn 4-8

(5), wheat 4-8

(6), bone meal 1.5-2.5

(7), conch meal 2.5-3.5

(8), lotus seeds 0.8-1.2

(9), kuh-seng 0.8-1.2

(10), mashed garlic 0.8-1.2

Above-mentioned raw materials pulverize-is mixed-dry-granulate, make synthetic diet;

F, feed injected volume;

(1), feeding volume is 2.5-3.5% of a fish body gross weight synthetic diet day;

(2), green grass, algae, the green vegetable leaf green fodder of joining pulverizing in right amount thrown something and fed;

(3), reach to remain on more than 15 ℃ the time, per 5-7 days, press 1000/m in water temperature ²The water surface is executed slaking fertilizer 100-150kg, or green manuring 150-250kg, to cultivate the plankton natural food;

The present invention cultures grass carp as stated above, and the breed grass carp meat embrittlement through more than 130 days becomes colory crisp grass carp.

Embodiment

1, carries out processing, pond water treatment at the bottom of the crawl as previously mentioned;

2, throwing fish puts in a suitable place to breed;

(1), grass carp 0.09-0.11kg/ tail 1000 tails, join the silver carp of putting the equivalent weight size, crucian, carp totally 350 tails;

(2), grass carp 0.4-0.6kg/ tail 1000 tails, join the silver carp of putting the equivalent weight size, crucian, carp totally 170 tails;

(3), grass carp 0.8-1.2kg/ tail 1000 tails, join the silver carp of putting the equivalent weight size, crucian, carp totally 240 tails;

(4), grass carp 1.8-2.2kg/ tail 1000 tails, join the silver carp of putting the equivalent weight size, crucian, carp totally 220 tails;

3, synthetic diet preparation weight ratio;

(1), broad bean 50

(2), trash fish 20

(3), carrot 10

(4), corn 6

(5), wheat 6

(6), bone meal 2

(7), conch meal 3

(8), lotus seeds 1

(9), kuh-seng 1

(10), mashed garlic 1

Respectively bone, shell, broad bean, corn, wheat, lotus seeds, kuh-seng are pulverized, trash fish, carrot, garlic are mixed pulverize, then above-mentioned raw materials is mixed-dry-granulate, make synthetic diet;

3, by preceding method throw something and feed synthetic diet and green fodder;

4, breed gets crisp grass carp more than 130 days.
