Abstract

The invention discloses a quick culture method for naked carp of Qinghai lake. Several aspects such as aquaculture facility selection, aquaculture environment regulation, released density and bait feeding and daily management are researched, and a reasonable set of aquaculture method is finally determined. By adopting the method, each released fish fry of the naked carp of the Qinghai lake with the body length of 5cm grows to 80-100g in the first year, 500-700g in the second year and more than 1,000g in the third year, and the growth rate is 5 to 8 times higher than the growth rate of wild naked carp of the Qinghai lake in the source area.

Description

A kind of Gymnocypris prezewalskii forms method fast
Technical field
The present invention relates to aquaculture field, be specifically related to a kind of Gymnocypris prezewalskii and form method fast.
Background technology
Gymnocypris prezewalskii belongs to Osteichthyes Cypriniformes (Cypriniformes) Cyprinidae (Cyprini-dae) Schizothoracinae (Schizothoracinae) Gymnocypris, also known as " Gymnocypris przewalskii ", only be distributed in Qinghai lake and water system thereof, for low temperature in plateau saline alkali waters economic fish, happiness inhabits limit, beach, between large clitter, flowing water is slowly located, during pool or rock stitch, strong adaptability, all can live in brackish water (Qinghai Lake Water salt content 12 ~ 13 ‰) or fresh water, omnivorousness, mainly ingest algae, wheel animalcule, shell-fish, aquatic insect and small fish, the main ingestion animal bait of juvenile fish, adult fish still ingests when egg-laying migration, but food ration declines.Naked carp is distributed in Qinghai Lake and tributary thereof, and Kreuk lake, Gyaring Lake, Ngoring Hu also produce naked carp.It is the very important economic fish in Qinghai Province.The sturdy grossness of naked carp body, meat flavour is fresh and tender plump, nutritious, and fat content is up to 12%, and protein 16.14%, welcomes by the masses deeply.
From the sixties in 20th century, around Qinghai Lake, hundreds of thousands mu grassland is opened up wasteland as farmland; Being built a dam by artificial barrage in 108 rivers flowing into Qinghai Lake, blocks breeding passage, and many rivers die out cutout, cause naked carp cannot lay eggs in fresh water, causes a large amount of naked carp dead in area, river mouth.Interrelated data shows, the existing naked carp stock number of Qinghai Lake is about 7500 tons, 1/10 of not enough initial stage of development, and at present, and the birds that Bird Island is perched will eat the naked carp of nearly kiloton every year, and the exhaustion of naked carp resource makes the existence of birds cause serious threat virtually.Qinghai Lake is the maximum inland saltwater lake of Chinese area, and it together constitutes the ecological protective screen stopping that western desert dust storm spreads eastwards with the native pasture in huge water body and basin, be the important place of world's bio-diversity conservation.Gymnocypris prezewalskii is unique a kind of large-scale wild economic fish in Qinghai Lake.Due to the living environment that it is special, Gymnocypris prezewalskii growth rate is very slow, and approximately weightening finish 0.5 kilogram in every 10 years, fertility is lower, and the population recruitment time is longer.
Domestic except have a small amount of cultivation at original producton location Qinghai Lake periphery except at present, other places cultivate the little of Gymnocypris prezewalskiis, and main cause is exactly poor growth, thus increase aquaculture cost.
Summary of the invention
Object of the present invention is exactly for above-mentioned technical problem; a kind of Gymnocypris prezewalskii is provided to form method fast; the method can accelerate the growth rate of Gymnocypris prezewalskii; marketable fish is formed within the shortest time; protect wild Gymnocypris prezewalskii resource; alleviate wild resource and disorderly catch phenomenon, make the dining table of common people increases an excellent aquatic products kind be of high nutritive value.
The technical solution used in the present invention:
A kind of Gymnocypris prezewalskii forms method fast, and it comprises the steps:
