Abstract
The invention relates to a cultivating method of a giant salamander. The cultivating method comprises the following steps of: selecting healthy and regular fries, and cultivating fries with weight less than 400 g in fresh water; cultivating in low-salinity sea water with specific gravity of 0.02-0.04 when the fries grow to 400-500 g, wherein the cultivating temperature is 12-22 DEG C and the dissolved oxygen is not lower than 5 mg/L; feeding bait at least twice every day, wherein the daily feeding amount is 10-20% of the weight of the fish; disinfecting once every 15-20 days in the cultivating stage, and disinfecting in fresh water and sea water mixture with the specific gravity of 0.1-0.2 when the fries grow to 400-500 g; and disinfecting in fresh water and sea water mixture with the specific gravity of 0.2-0.4 for 0.25-2 hours when the fries grow to more than 500 g. The cultivating method has the advantages that: natural bait is fed, the fries grow fast, the problem of high incidence rate is solved, the cultivating period is shot, and the market requirement is met.
Description
Technical field
The present invention relates to the cultural method of a kind of giant salamander, belong to fishery ecologic breeding technology.
Background technology
The giant salamander is not fish, be existing maximum also be most precious amphibian; Be country two types of protections aqua-marine life, the delicious meat of the giant salamander, fertile and oiliness; The amino acid that contains needed by human promotes Human Physiology active, is described as the living person's ginseng in the water; Its medical value is also very high, can extract antioncogene; Its cosmetic values is very high, can regulate microcirculation in human body, the prevention heavy metal poisoning.But the giant salamander is famous and precious kind, along with the pollution aggravation of developed area, suffers that for a long time people catch and kill in a large number, and each place of production quantity falls sharply; Cultivate the artificial giant salamander, meet the need of market, the giant salamander of artificial culture; Usually need 2 years half to 3 year, cultivation period is long, has satisfied not the demand in market; Some is propagated artificially, adopts chemical agent to carry out disinfection, and this growth to fish own has certain influence.Therefore, need provide a kind of new technical scheme to solve the problems referred to above.
Summary of the invention
The cultural method that the purpose of this invention is to provide the giant salamander that a kind of culture-cycle is short, health is harmless.
The technical scheme that the present invention adopts is:
The cultural method of a kind of giant salamander,
Select fry healthy, neat specification, fry is cultured in fresh water less than 400g's; When fry length arrived 400-500g, selecting proportion was the low salinity seawater breeding of 0.02-0.04, and culturing temperature is 12-22 ℃, and dissolved oxygen is not less than 5mg/L;
Every day is bait throwing in material secondary at least, and the quantity of throwing something and feeding day is the 10%-20% of fish body weight;
During the breed, every carried out disinfection once at a distance from 15-20 days, fry is long during to 400-500g, in proportion is the mixing water of 0.1-0.2 fresh water and seawater, sterilizes; Long when fry to more than the 500g,, proportion sterilizes in being the mixing water of 0.2-0.4 fresh water and seawater, and disinfecting time is 0.25-2 hour.
Said bait is the red awns shrimp that lives in the sea area, one or more in small fish and the white shrimp.
Advantage of the present invention: drop into nature bait, the fry growth has solved the high problem of the incidence of disease rapidly; Culture the giant salamander delicious meat of coming out, 1 year half manhood, lacked 1 year than other areas; When length arrived 2-3 jin, generally near 3 years, as long as the giant salamander of breed of the present invention was 2 years; Cultivation period is short, meets the need of market.
Embodiment
Below embodiment in order to explanation the present invention, but do not limit the present invention.
Embodiment 1
The cultural method of a kind of giant salamander of the present invention is selected fry healthy, neat specification, and fry is cultured in fresh water less than 400g's; When fry length arrived 400g, selection proportion was 0.02 low salinity seawater breeding, and culturing temperature is 12 ℃, and dissolved oxygen is not less than 5mg/L; Bait throwing in every day material secondary, bait are the red awns shrimp that lives in the sea area, and the quantity of throwing something and feeding day is 10% of fish body weight; During the breed, every at a distance from 15 days, carry out disinfection once; Fry is long during to 400g, in proportion is the mixing water of 0.1 fresh water and seawater, sterilizes, and disinfecting time is 0.25 hour; Fry is long during to 550g, in proportion is the mixing water of 0.2 fresh water and seawater, sterilizes, and disinfecting time is 0.4 hour.
Embodiment 2
The cultural method of a kind of giant salamander of the present invention,
Select fry healthy, neat specification, fry is cultured in fresh water less than 400g's; When fry length arrived 450g, selection proportion was 0.03 low salinity seawater breeding, and culturing temperature is 17 ℃, and dissolved oxygen is not less than 5mg/L; Bait throwing in every day material three times, bait are the small fish of living in the sea area, and the quantity of throwing something and feeding day is 15% of fish body weight; During the breed, every at a distance from 17 days, carry out disinfection once; Fry is long during to 450g, in proportion is the mixing water of 0.15 fresh water and seawater, sterilizes, and disinfecting time is 0.3 hour; Fry is long to 800g, in proportion is the mixing water of 0.3 fresh water and seawater, sterilizes, and disinfecting time is 0.55 hour.
Embodiment 3
The cultural method of a kind of giant salamander of the present invention is selected fry healthy, neat specification, and fry is cultured in fresh water less than 400g's; When fry length arrived 500g, selection proportion was 0.04 low salinity seawater breeding, and culturing temperature is 22 ℃, and dissolved oxygen is not less than 5mg/L; Bait throwing in every day material four times, bait are the red awns shrimp that lives in the sea area, small fish and white shrimp, and the quantity of throwing something and feeding day is 20% of fish body weight; During the breed, every at a distance from 20 days, carry out disinfection once; Fry is long during to 500g, in proportion is the mixing water of 0.2 fresh water and seawater, sterilizes, and disinfecting time is 0.35 hour; Fry is long to 1000g, in proportion is the mixing water of 0.4 fresh water and seawater, sterilizes, and disinfecting time is 2 hours.
