Abstract
The invention relates to a southern catfish fry cultivation method. The southern catfish fry cultivation method comprises selecting a culture pond, cleaning the pond, adding nutrition, culturing zooplanktons, putting fries into the pond and grading and diving the fries. The size of the culture pond is from 2 to 3 mu and the culture pond is close to a water source; a layer of sludge paves at the bottom of the pond; the thickness of the sludge relates to the height of the culture pond. 100 kilograms of unslaked lime is thrown into every mu of culture pond. Over rotten feces is sprayed into the culture pond and water drains into the culture pond to dilute the feces. The water color dims to be dark brown three to six days after the water color changes to be green; 50 to 70cm water is injected into the culture pond; the fries can be arranged inside the pond to be cultured when tiny zooplankters can be seen by naked eyes two days later. When yolk sacs which hatched fries disappeared, the fries can be put into the pond when the body color of the fries are changed to be black brown from faint yellow and the fries can flatly swim, wherein the water temperature is from 23 to 26 degrees and the released density is from 0.1 million to 0.15 million every mu. The southern catfishes are sieved to be cultured with levels and pond being divided two days after getting out of membranes. According to the southern catfish fry cultivation method, the cultured southern fries are sufficient in nutrient and the survival rate is about 80%.
Description
Technical field
The present invention relates to fry rearing field, particularly relate to a kind of fry rearing method of southern catfish.
Background technology
Southern catfish is famous and precious nutrient excellent product, just on the books in history records, can compare favourably with shark's fin, wild soft-shelled turtle, its dietary function, such as nourishing yin and nourishing blood, bowl spares gas, appetizing, diuresis are not available for other fish, and fine and tender taste, the protein contained is more, is the essential food of women's dietotherapy in postpartum nourishing.Therefore, along with extensively fishing for of the mankind, southern catfish quantity sharply reduces, people start propagating artificially of southern catfish gradually, the key of cultivation is fry rearing, which dictates that the survival rate in the later stage of southern catfish, the problem that the fry survival rate of the technique of fry rearing of existing southern catfish is low and nutrition is insufficient.
Summary of the invention
Object of the present invention is intended to the difficult problem that fry survival rate is low and nutrition is insufficient of the technique of fry rearing solving southern catfish, and provides a kind of fry rearing method of southern catfish.
The present invention for achieving the above object, provides a kind of fry rearing method of southern catfish, comprise cultivate pond selection, clean up the pond, nutrition is added, zooplankton is cultivated, spray enters point fraction pond of pond, fry.
Cultivate the selection in pond: cultivating pond size is 2 ~ 3 mu, cultivate pond near water source, spread one deck mud at the bottom of pond, silt depth is relevant with the height cultivating pond.
Clean up the pond: cultivate the quicklime that every mu, pond sheds 100 kilograms.
Nutrition is added: cultivate in pond and spray into the ight soil become thoroughly decomposed, discharge water dilution.
Zooplankton is cultivated: 3 ~ 6 days water colour become green rear thin out be dark brown, wash by water dark to 50-70cm, in the water that is visible to the naked eye, occur that after 2 days the tiny zooplankton flower that can discharge water enters pond cultivation.
Spray enters pond: when the yellow capsule of incubating of hatching prelarva disappears, body colour becomes pitchy by faint yellow, and when can put down trip, namely descend pond, water temperature 23-26 DEG C, breeding density is 100,000-15 ten thousand tails/mus.
Point fraction pond of fry: southern catfish membrane sieves two days later, point fraction pond is raised.
Described nutrition is added, and in cultivation pond, every mu sprays into 250 kilograms of poultry-dungs become thoroughly decomposed, and discharges water to depth of water 23-30cm.
Described nutrition is added, and in cultivation pond, every mu sprays into 400 kilograms of livestock excrement become thoroughly decomposed, and discharges water to depth of water 23-30cm.
The invention has the beneficial effects as follows: the method for the invention, to raise the fry nutrition of the southern catfish come abundant, survival rate is generally about 80%.
Embodiment
Be described in detail below with reference to embodiments of the invention.
A fry rearing method for southern catfish, comprise cultivate pond selection, clean up the pond, add nutrition, zooplankton is cultivated, spray enters point fraction pond of pond, fry.
Cultivate the selection in pond: cultivating pond size is 2 ~ 3 mu, cultivate pond near water source, spread one deck mud at the bottom of pond, silt depth is relevant with the height cultivating pond.
Clean up the pond: cultivate the quicklime that every mu, pond sheds 100 kilograms.
Nutrition is added: cultivate in pond and spray into the ight soil become thoroughly decomposed, discharge water dilution.
Zooplankton is cultivated: thin out gradually after water colour change in 3 ~ 6 days is green is dark brown, washes by water dark to 50-70cm, occurs that tiny zooplankton can discharge water spend pond to cultivate after 2 days in the water that is visible to the naked eye.
Spray enters pond: when the yellow capsule of incubating of hatching prelarva disappears, body colour becomes pitchy by faint yellow, and when can put down trip, Ke Xiachi, water temperature 23-26 DEG C, breeding density is 100,000 ~ 150,000 tails/mu.
Point fraction pond of fry: because southern catfish membrane prelarva two days later has the nature mutually killed and devour, should sieve in time, point fraction pond is raised; Sufficient at living bait, water quality is pure and fresh, under the condition of dissolved oxygen abundance, only needs 10-15 days, can reach more than 3cm specification.
Described nutrition is added, and in cultivation pond, every mu sprays into 250 kilograms of poultry-dungs become thoroughly decomposed, and discharges water to depth of water 23-30cm.
Described nutrition is added, and in cultivation pond, every mu sprays into 400 kilograms of livestock excrement become thoroughly decomposed, and discharges water to depth of water 23-30cm.
Protection scope of the present invention is not limited thereto, and any those of ordinary skill in the art are in the technical scope disclosed by the present invention, and the change can expected without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection domain that protection scope of the present invention should limit with claims is as the criterion.
