Abstract

A domestication method for full-forage-fed rana nigromaculata is disclosed. In first year, rana nigromaculata eggs are placed in a wildness imitating environment for culturing and fed with live baits. In a second year, when rana nigromaculatas completely turn into froglets from tadpoles and clime on land, the rana nigromaculatas are fed with live baits for a month. The live baits are gradually reduced, and the rana nigromaculatas are fed with forages mixed in the live bait, and the proportion of forages is gradually increased until the rana nigromaculatas are completely fed with forages. In the third year, when rana nigromaculatas completely turn into froglets from tadpoles and clime on land, the rana nigromaculatas are directly fed with forages. After feeding for one month, some froglets have adverse reaction and are deselected, and some froglets are accustomed to forage feeding. In the fourth year, rana nigromaculatas are cultured in a pool and fed with forages. The domestication method overturns tradition, the production cost is lowered, and labor is reduced. The full-forage-fed rana nigromaculata is suitable for large-scale industrialized production, the growth period is substantially shortened, and the output is substantially increased and reaches one thousand five hundreds kg/mu. The economic benefits are increased substantially.

Description

A kind of acclimation method of full feedstuff Rana nigromaculata kind

Technical field

The present invention relates to aquaculture field, be specifically related to the acclimation method of a kind of full feedstuff Rana nigromaculata kind.

Background technology

The batrachia that Rana nigromaculata right and wrong are usually shown in, belongs to Ranidae, Anura, Amphibian.The fine and tender taste of Rana nigromaculata, fat Less, sugar is low, protein content is high, has effect of heat-clearing and toxic substances removing, reducing swelling and alleviating pain, the letter of artificial cultivation Rana nigromaculata not only technology Single, and economic well-being of workers and staff is fast, and therefore, the cultivation of Rana nigromaculata is the focus of aquaculture.

At present, the breeding process of Rana nigromaculata is all use animal as bait, such as: beach louse, Limnodrilus hoffmeisteri etc., uses these Animal is as bait, and cost is high, needs to expend a large amount of stock of manpower bait, and labor intensity is big, and be unsuitable for industrialized greatly Large-scale production, it addition, the Rana nigromaculata growth cycle fed by animal feed is long, yields poorly, and economic benefit is low.

Summary of the invention

The technical problem to be solved is, overcomes the drawbacks described above that prior art exists, it is provided that one overturns biography System, uses the acclimation method of the full feedstuff Rana nigromaculata kind of full forage feed Rana nigromaculata.

The technical solution adopted for the present invention to solve the technical problems is, the domestication side of a kind of full feedstuff Rana nigromaculata kind Method, First Year, Rana nigromaculata Rana ovum is cultivated in imitative wild environment, live bait of throwing something and feeding, First Year second half year, select stiffness of the body body What strong, color was good-looking the become kind frog that the frog makees next year；Second Year, after the froglet of Rana nigromaculata completes abnormal disembarkation, throws with live bait Feeding one month, afterwards, gradually decrease the amount of live bait, the feedstuff that adulterates in live bait is thrown something and fed, and the ratio of throwing something and feeding of feedstuff gradually carries High until all using feedstuffs to throw something and feed, Second Year second half year, selecting strong one-tenth with becoming in the frog of feedstuff feeding The frog makees the kind frog of next year；3rd year, after the froglet of Rana nigromaculata completes abnormal disembarkation, directly with feedstuff feeding, froglet had Untoward reaction, after persistently throwing something and feeding one month with feedstuff, part froglet is eliminated, and part froglet custom feedstuff feeding, under the 3rd year Half a year, in becoming of custom feedstuff feeding, the frog selects the strong kind frog becoming the frog to make next year full feedstuff Rana nigromaculata kind； 4th year, frog pond cultivates Rana nigromaculata, feedstuff of throwing something and feeding.

Further, the ratio of throwing something and feeding of described feedstuff gradually steps up, and the ratio of throwing something and feeding starting feedstuff is 0, afterwards, and feedstuff and work The ratio of bait is followed successively by 1:10,1:9,1:8,1:7,1:6,1:5,1:4,1:3,1:2,1:1, finally, all uses feedstuff to carry out Throw something and feed.

Further, the kind frog of described full feedstuff Rana nigromaculata kind should select from multiple plants, it is to avoid inbreeding.

Compared with prior art, the method have the advantages that method is easy, strong operability, easily grasp；Overturn biography System, reduces production cost, solves amplification quantity labour force, is suitable to large-scale industrialized production, and growth cycle is greatly shortened, and yield is significantly Improving, remarkable in economical benefits increases.

Detailed description of the invention

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

Embodiment

The present embodiment, First Year, Rana nigromaculata Rana ovum is cultivated in imitative wild environment, live bait of throwing something and feeding, under First Year Half a year, select the kind frog becoming the frog to make next year strong, that color is good-looking；Second Year, the froglet Rana nigromaculata completes metamorphosis After disembarkation, throwing something and feeding one month with live bait, afterwards, gradually decrease the amount of live bait, the feedstuff that adulterates in live bait is thrown something and fed, feedstuff The ratio of throwing something and feeding gradually steps up until all using feedstuff to throw something and feed, Second Year second half year, is selecting with in the one-tenth frog of feedstuff feeding Select the strong kind frog becoming the frog to make next year；3rd year, after the froglet of Rana nigromaculata completes abnormal disembarkation, directly use feedstuff Throwing something and feeding, froglet has untoward reaction, and after persistently throwing something and feeding one month with feedstuff, part froglet is eliminated, part froglet custom feedstuff Throw something and feed, the 3rd year second half year, select the strong one-tenth frog to make next year full feedstuff black speck in becoming in the frog of custom feedstuff feeding The kind frog of frog kind；4th year, frog pond cultivates Rana nigromaculata, feedstuff of throwing something and feeding.

In the present embodiment, the ratio of throwing something and feeding of described feedstuff gradually steps up, and the ratio of throwing something and feeding starting feedstuff is 0, afterwards, feedstuff It is followed successively by 1:10,1:9,1:8,1:7,1:6,1:5,1:4,1:3,1:2,1:1 with the ratio of live bait, finally, all uses feedstuff Throw something and feed.

In the present embodiment, the kind frog of described full feedstuff Rana nigromaculata kind should select from multiple plants, it is to avoid near Hand over.

Overturning tradition, reduce production cost, solve amplification quantity labour force, be suitable to large-scale industrialized production, growth cycle is big Big shortening, yield is greatly improved, per mu yield reach three very heavy more than, remarkable in economical benefits increases.
