Abstract

The invention discloses a method for breeding pelteobagrus fulvidraco. The method is as follows: when the body of the pelteobagrus fulvidraco is shorter than 5 cm, feeding fresh maggots with a total body weight accounting for 2-4% of that of the pelteobagrus fulvidraco in the breeding bond and small penaeus monodon with a total body weight accounting for 4-6% of the same; when the body of the pelteobagrus fulvidraco is longer than 5 cm, feeding the fresh maggots with a total body weight accounting for 3-4%, live earthworms with a total body weight accounting for 1-2% and small trash fish with a total body weight accounting for 2-3% of the same. According to the invention, the fresh maggots, the small penaeus monodon, the live earthworms and the small trash fish are used as feedstuff during breeding, which obviously increases the food intake of the pelteobagrus fulvidraco because the fresh maggots, the small penaeus monodon, the live earthworms and the small trash fish are all high-protein foods which can effectively increase the body weight of the bred pelteobagrus fulvidraco; a breeding environment is basically the same as a wild environment, which ensures that the flavor of the bred pelteobagrus fulvidraco remains the same as that bred in the wild environment; the technology provided by the invention can effectively shorten the breeding period to half a year, and enables the body weight to increase by 5-10% and the body length of an individual to exceed 130 mm generally.

Description

The cultural method of a kind of yellow cartfish

Technical field

The present invention relates to aquaculture field, particularly relate to the cultural method of a kind of yellow cartfish.

Background technology

Yellow cartfish delicious meat, high nutritive value, records in " medical center collection is wanted ": yellow cartfish nature and flavor are sweet flat, the beneficial taste of energy, inducing diuresis to reduce edema; But due to the characteristic of yellow cartfish self, poor growth in breeding process, head is less than normal, and general body length is at 103-123mm, and present propagating artificially simultaneously reduces the local flavor of yellow cartfish self, have impact on sales volume, virtually reduces economic benefit during cultivation.

Summary of the invention

The object of this invention is to provide a kind of Shortening culturing period, increase the yellow cartfish cultural method of individual weight, ensure that the yellow cartfish cultivating out keeps wild local flavor simultaneously.

The technical scheme taked in order to the present invention that solves the problem is:

The cultural method of a kind of yellow cartfish

The choosing of culturing pool is built: culturing pool area is set to 2-4 mu, dark 1.2-1.5m, note draining is convenient, oxygen increasing pump is provided with in culturing pool, at the bottom of culturing pool, plant appropriate hornwort and black algae before water filling, cultivated area is 15% of culturing pool area, and pond bottom lays the thin river sand of one deck 10-15cm, put front 10-15 days in a suitable place to breed and drain water in culturing pool, kill virus with quicklime comprehensively.

Put in a suitable place to breed: every mu of culturing pool puts the juvenile fish 2000-3000 tail of 2-3cm in a suitable place to breed, put silver carp 100-200 tail in a suitable place to breed, loach 100-200 tail, spiral shell 2-3kg for every mu simultaneously.

Daily management: changed a Chi Shui every 10-15 days, more quantity of exchanged water accounts for the 1/4-1/3 of culturing pool total Water at every turn, it is main that damage by disease and insect has been prevented and treated, carries out sterilization every other month with low concentration liquor potassic permanganate to Chi Shui, finds that pest will be removed in time.

Daily feed: when long below the 5cm of body, throw something and feed the every day fresh fly maggot accounting for the total scale of construction 2%-4% of fish in culturing pool and the little grass shrimp accounting for the total scale of construction 4%-6% of fish in culturing pool; Body long more than 5cm time, throw something and feed every day and account for the small fish of the fresh fly maggot of the total scale of construction 3%-4% of fish in culturing pool, the earthworm alive of 1%-2% and 2%-3%.

Beneficial effect of the present invention: the present invention adopts fresh fly maggot, little grass shrimp, earthworm alive and small fish to be feed when raising, obviously can increase the food-intake of yellow cartfish when ingesting, fly maggot, little grass shrimp, earthworm alive and small fish are all the body weight that high protein food effectively can increase cultivation fish body, feeding environment and wild environment are substantially identical, ensure that the local flavor cultivating out yellow cartfish is constant, adopt technology of the present invention, effectively can reduce the culture-cycle reaches half a year, body weight increases 5%-10%, and individual body is long generally more than 130mm.
