Abstract

An underground cultivating method for giant salamanders includes the steps: arranging a cultivating room 5-7 meters below the ground surface, and arranging a plurality of independent cultivating ponds in the cultivating room, wherein each cultivating pond is a square glass pond with the top open, the top of each cultivating pond is provided with a water inlet, and the bottom of each cultivating pond is provided with a drainage outlet; collecting underground water below 600 meters to be used as water in the cultivating ponds, maintaining the temperature at 18-22 DEG C, and keeping flowability of the water in the cultivating ponds; arranging the length X width X height of each cultivating pond as 150-200centimetersX80-120centimetersX80-100centimeters, and stocking 3-4 giant salamanders in each cultivating pond; and throwing crucian live bait 8-10 times of the giant salamanders in number into each cultivating pond, and throwing once each day after checking, wherein the length of each crucian ranges from 2 centimeters to 6 centimeters. The underground cultivating method for the giant salamanders has the advantages that the method for cultivating the giant salamanders is extremely applicable to northern regions, and since the underground cultivating room is constant in temperature, the giant salamanders can be caught and eaten throughout the year, and growth speed of the giant salamanders is higher than natural growth speed.

Description

The underground cultural method of giant salamander

Technical field

The present invention relates to the breed of giant salamander.

Background technology

Giant salamander also claims the giant salamander, belongs to national second class protection animal, mainly originate in the mountain stream river in the Changjiang river, the Yellow River and Zhujiang River middle and upper reaches tributary, and be many with provinces such as Sichuan, Hubei, Hunan, Guizhou, Shaanxi especially.Giant salamander happiness the moon keeps in dark place, and growth rate is slower, and its suitable temperature range is 16～25 ℃, when water temperature below 10 ℃ or more than 26 ℃ the time, food ration descends.Water temperature begins hibernation when dropping to below 4 ℃, is raised to and just enters aestivation more than 28 ℃, all stops feed fully.Therefore taking 5～6 years under the carded sliver spare out of office can sexual maturity, and it is lower that it propagates success rate artificially, and especially at northern area, giant salamander artificial propagation growth is more slow.

Summary of the invention

The underground cultural method that the purpose of this invention is to provide a kind of giant salamander can improve the northern area giant salamander greatly and propagate success rate artificially, and fast growth.

In order to achieve the above object, the technical solution used in the present invention is:

The underground cultural method of a kind of giant salamander is characterized in that: 5-7 meters are provided with culturing chamber below the face of land, are provided with some ponds of independently culturing in the culturing chamber, and culturing the pond is the square glass pond of open-top, and is provided with water inlet, and its bottom is provided with the dewatering outlet;

The above cultures in pond hydromining from dark underground water below 600 meters, and keeps 18-22 ℃ of temperature, enters from water inlet and cultures the pond, and discharge from the dewatering outlet, keeps culturing the flowability of pool inner water;

The wide * height of the above each breed long * in pond is 80-100 centimetres of 80-120 centimetres of * of 150-200 centimetres of *, puts giant salamander 3-4 tails in the pond in a suitable place to breed;

The above cultures 8-10 times of input crucian live baits pressing giant salamander in the pond, checks and throw in once that every crucian size is 2-6 centimetres every day.

The above culturing chamber temperature is controlled to be 19-21 ℃.

The invention has the beneficial effects as follows, adopt this method to culture the giant salamander, be suitable for very much northern area, because underground culturing chamber temperature constant can make the giant salamander search for food throughout the year, growth rate is fast than self-sow, and juvenile fish can grow to 1.5 jin in 1 year.

Embodiment

Build culturing chamber for 5-7 meters below the face of land, culturing chamber is provided with airtight hermatic door, is provided with some ponds of independently culturing in the culturing chamber, and culturing the pond is the square glass pond of open-top, and is provided with water inlet, and its bottom is provided with the dewatering outlet;

The above cultures in pond hydromining from dark underground water below 600 meters, and keeps 18-22 ℃ of temperature, enters from water inlet and cultures the pond, and discharge from the dewatering outlet, keeps culturing the flowability of pool inner water;

The wide * height of the above each breed long * in pond is 80-100 centimetres of 80-120 centimetres of * of 150-200 centimetres of *, puts giant salamander 3-4 tails in the pond in a suitable place to breed;

The above cultures 8-10 times of input crucian live baits pressing giant salamander in the pond, checks and throw in once that every crucian size is 2-6 centimetres every day.

The above culturing chamber temperature is controlled to be 19-21 ℃.

Detected culturing pool inner water in per 1-2 days, and guaranteed water quality reaching standard.

Should be noted that embodiment of the present invention only is its optimal way, to belonging to general idea of the present invention, and only is apparent change, all should belong within protection scope of the present invention.
