Abstract

The invention discloses a non-dormancy high-yield standardized breeding technique for giant salamander, which is implemented mainly through carrying out manual temperature control by using underground warm water so as to keep the water temperature between 16.5+/-0.5 DEG C, therefore, a situation that giant salamander grows in a non-dormancy state all year round is effectively ensured, and the breeding time for obtaining marketable giant salamander is 3-3.5 years, compared with a traditional breeding method by which the breeding time for obtaining marketable giant salamanders is 5 years, 1-1.5 years are shortened; and through breeding giant salamander alternately in different giant salamander pools by turns semiannually, monthly carrying out sterilization on a using giant salamander pool by using a potassium permanganate solution with a volume of 15-25 g/m<3>, and weekly soaking giant salamander and giant salamander pools by using a NaCl solution with a volume of 50 g/m<3>, a good disease prevention effect can be achieved. Compared with the traditional breeding techniques which are implemented only by maintaining daily water changing without alternately breeding giant salamander in different giant salamander pools by turns or sterilizing, by using the technique disclosed by the invention, about 37% of epidemic-disease occurrence probability is reduced.

Description

Giant salamander does not have dormancy high yield standardization cultural technique

Technical field

The invention belongs to aquatic animal cultural technique field, particularly a kind of giant salamander does not have the normalized cultural technique of dormancy high yield.

Background technology

Giant salamander is commonly called as the giant salamander, and amphibian is China second class protection animal, has scientific research, cuisines, views and admires, keeps healthy, value such as medicine, has the prospect of development and use widely, paid close attention to by various circles of society.In recent years along with the breakthrough of giant salamander raising technology; The seedling breeding amount just increases progressively year by year at double; Various places are carried out giant salamander and are tamed and dociled numerous, the field point of culturing and scale also in continuous rising; Breed the further increase of total amount along with giant salamander; Will form huge pressure to the giant salamander culture industry when the time comes; Pressure one is the lifting of culturing total amount, must strengthen the basis input of breeding facility and administrative staff's manual work input; Pressure two is that the lifting of culturing total amount does not match with present breed level; Lack the necessary technology support owing to culture the peasant household of main body; Culture lack of standardization; Cultivation density is excessive; Eqpidemic disease generation probability will be far longer than present present situation, has brought huge hidden danger for the healthy and strong sound development of giant salamander industry; Pressure three is to culture total amount further to promote, but output but needs the time in 4 years-5 years according to present breed level, behind 4-5, will form the concentrated period of an output so, forms huge pressure to selling, and will inevitably injure aquaculture; Pressure four is that a large amount of giant salamander resources overstocks in peasant household's hand, needs the experience 4-5 year just can come into the market, and has tied up the development fund of giant salamander industry on the one hand in a large number, on the one hand peasant household is formed huge economic risk.

Summary of the invention

The purpose of this invention is to provide a kind of artificially controlling temperature that passes through, break the giant salamander dormancy, improve the speed of giant salamander growth, shorten its growth cycle, and cooperate effective eqpidemic disease preventive measure, reduce a giant salamander culture technology of eqpidemic disease generation probability.

The technical scheme that realizes above-mentioned purpose is: giant salamander does not have the efficient cultural technique of dormancy and comprises following step:

Embodiment

1, the selection of water quality: select phreatic water or spring for use, water quality meets " fresh water fishery breed standard ", pH value between 6.3-7.5, oxygen content amount 5-6mg/L.

2, temperature control measure:, regulate and control temperature of cultivation to 16.5 ℃ ± 0.5 ℃ through the temperature that the underground water different depth is had.

3, wheel is pool cultivated: change the salamander pond every half a year one time, take turns dried putting behind the sterilizing of used salamander pond pool cultivated again half a year.

4, sterilizing measure: every month 15-25g/m of 1 time ³The liquor potassic permanganate of water body is to the salamander pond sterilization used and 1 time 50g/m weekly ³The NaCl solution of water body soaks 2h to giant salamander and salamander pond.

5, cultivation density: the cultivation density before age half a year is with 200 tails/m ²For good, giant salamander to 1 age age half a year giant salamander with 80 ± 10 tails/m ²For good, 1 the age at age to 2 giant salamander with 7-8 tail/m ²For good, 2 giant salamander to 3 age at age giant salamander with 4 ± 1 tails/m ²For good; Also can arrange cultivation density according to body weight, in every tail 5g-50g stage breeding density with 200 tails/m ²For good, 50g-500g stage breeding density with 80 ± 10 tails/m ²For good, 500g-1200g stage breeding density with 7-8 tail/m ²For good, 1200g-2500g stage breeding density with 4 ± 1 tails/m ²Tail.

6, different bait are fed: 1 jin to the Giant Salamander Breeding process of 5 jin of weights, adopt feeding river prawn and small fish can effectively improve grazing rate and the nutrition supply of giant salamander.

Beneficial effect of the present invention:

One of which: under 16.5 ℃ ± 0.5 ℃ condition, culture through the Artificial Control water temperature; Make giant salamander be in annual no resting state low-temperature epitaxy; 5 years of being cultured by tradition of the growth cycle that makes giant salamander shortened to 3 years-3.5 years, and were unlikely to make the body immunity decline to cause the generation of eqpidemic disease.

Its two: pool cultivated and used 15-25g/m in every month through every half a year wheel ³The liquor potassic permanganate of water body is to the salamander pond sterilization used and 1 time 50g/m weekly ³The NaCl solution of water body soaks 2h to giant salamander and salamander pond, can play eqpidemic disease preventive effect preferably, with the not alternate culture of falling the pond, not sterilizing, only keep daily tradition breed measure of changing water and compare eqpidemic disease generation probability reduction about 37%.

Claims

1. efficient cultural technique of no dormancy giant salamander; It is characterized in that: the temperature that is had through the underground water different depth; Regulation and control temperature of cultivation to 16.5 ℃ ± 0.5 ℃ can make giant salamander breed the commodity salamander time and foreshorten to 3-3.5, shortens 1-1.5 than conventional cultivation method.
