Abstract

The invention discloses a grass carp culturing method. The grass carp culturing method comprises the following steps of (1) cleaning and neatening a pond as needed under the conditions that the suitable area of the pond is 10-20 acre, the depth of water is 2-2.5 meters, and the thickness of sludge is smaller than or equal to 20 centimeters; (2) breeding fingerlings under the condition that 300 grass carp fingerlings, 300 golden carp fingerlings, 50 silver carp fingerlings and 10 bighead carp fingerlings are bred in each acre, the weight of each grass carp fingerling is 200-250 kilos, the total weight of 15-20 golden carp fingerlings is one kilogram, and the total weight of 5-6 silver carp fingerlings is one kilogram; and soaking and sterilizing the fingerlings for 5-10 minutes by using 5% of salt solution before the fingerlings are bred; (3) feeding feedstuffs to the fingerlings under the condition that main feedstuffs are pellet feedstuffs, the protein content of the pellet feedstuffs is 28-32%, and auxiliary feedstuffs are green feedstuffs; and (4) managing water quality: aerating for 2 hours at 1-3 pm every afternoon in fine days without wind from June to October, and aerating at wee hours in good time. By using the grass carp culturing method, labor is greatly saved, the death rate of grass carps is reduced, the yield of the grass carps is improved, and the purposes of high yield and high quality are achieved. The grass carp culturing method has high popularization value.

Description

The method of the cultivation of a kind of grass carp

Technical field

The present invention relates to a kind of cultural method, the particularly method of the cultivation of a kind of grass carp, belongs to cultural technique field.

Background technology

Grass carp generally like perch in the waters such as rivers, lake, lower floor and many pasture and water of offshore region.The habit of tool You He lake migration, sexually matured individuality is laid eggs in the flowing water such as rivers, reservoir, parent population after laying eggs and juvenile fish enter in tributary and lake, Tongjiang, conventionally in the meadow, shoal not had by water logging and flashing region and the Heavenly Stems and Earthly Branches flow attached water body (pasture and water such as lake, river, gat grow thickly area) and ingest and fatten.Winter in master stream or the deep water place in lake survive the winter.Grass carp disposition is active, and swimming rapidly, often hunts in packs, and property voracity, is typical herbivorous fishes.Its fry stage the zooplankton that ingests, young stage hold concurrently food insect, earthworm, algae and duckweed etc., body is about while reaching more than 10 centimetres, the Aquatic Higher Plants of ingesting completely, wherein especially take gramineous plants as many.The floristics of Feeding in Grass Carp changes to some extent along with the situation on food basis in living environment.

Summary of the invention

The present invention is based on existing grass carp cultural method, adopt the principles of science of novelty, proposed the method for the cultivation of a kind of grass carp, it has greatly saved labour, has reduced the lethality of grass carp, has improved the output of grass carp, reaches the object of high yield and high quality.

The technical scheme that the present invention solves its technical problem employing is: the method for the cultivation of a kind of grass carp, its cultural method adopts following steps to realize.

(1) pond requires and levels: pond area is advisable with 10-20 mu, depth of water 2-2.5 rice, and silt depth is no more than 20 centimetres.Every 10 mu of pond match powers are each 1 of the aerator of 3 kilowatts and Autoamtic bait putting machine.Drain Chi Shui winter, freeze and shine more than 20 days.First 15 days of fingerling stocking, water inlet 10-20 centimetre, every mu with the sterilization of cleaning up the pond of 150 kilograms of quicklimes.(2) fingerling stocking: around the Spring Festival, every mu puts specification is grass carp kind 300 tails of 200-250 gram/fish, specification be 15-20 tail/kilogram crucian kind 300 tails, specification be 5-6 tail/kilogram silver carp kind 50 tails, Variegated 10 tails.Fingerling stocking is front with 5% saline solution soaking disinfection 5-10 minute.(3) feedstuff feeding: take the pellet of throwing something and feeding as main, dietary protein level is at 28-32%, auxiliary throwing green forage.Feedstuff feeding is followed the principle of " front thick after essence " and " four fixed four see ", and throw something and feed 2 general every day, eating up in 2 hours, 8 one-tenth of Feeding in Grass Carps satisfy and are advisable.The 3-6 month, the pellet take the protein content of throwing something and feeding as 28% was as main, and day throwing the rate of raising is 3%, the green fodder of throwing something and feeding in right amount; The 7-9 month, control pellet feeding volume, day throwing rate of raising is 1.5% left and right, pellet protein content is 28%, strengthens green fodder feeding volume, controls fish disease and occurs; The protein content of throwing something and feeding the 10-11 month is 32% pellet.Throw something and feed continuously after pellet a period of time, should stop to feed pellet 1 week, the former grain fodder of throwing something and feeding in interval.Note at ordinary times the appropriate medicines such as vitamin that add in feed, avoid grass carp to suffer from the diseases such as liver and gall syndrome and cause mortality.

(4) water quality management: correctly use aerator, the calm weather of 6-10 month fine day, the oxygenation 2 hours of starting shooting when 1-3 every afternoon, in good time oxygenation in morning; Cloudy day should be done sth. in advance oxygenation continuously.The new water of in good time annotating to pond, takes the way of " float little enter, repeatedly change water " progressively to regulate and control water quality.The 6-9 month, the new water 1 time of annotating every 3-5 days, the 10 centimetres of left and right that at every turn add water, change slurry full pool spilling head 1 time every 1 meter of depth of water of 15-20 days every mu of waters surface with 10-20 kilogram of quicklime.

Beneficial effect of the present invention: the method for the cultivation of a kind of grass carp that the present invention proposes, it has greatly saved labour, has reduced the lethality of grass carp, has improved the output of grass carp, reaches the object of high yield and high quality, has larger promotional value.

Embodiment

Below in conjunction with instantiation, the invention will be further described.
