Embodiment 1

[0043] A kind of training facility that improves the field survivability of cultured giant salamanders is selected next to a mountain stream, flat and open, with rich vegetation, including mountain spring water purification pond 1, giant salamander breeding pond 2, training pond 3, bait fish breeding pond 4 and mountain spring water Purification pond 1, giant salamander culture pond 2, training pond 3 and bait fish culture pond 4 are provided with water inlet and water outlet respectively; Described giant salamander culture pond 2 and training pond 3 periphery plant green plants, while building natural environment, as Shade, which also keeps the water warm;

[0044] The mountain spring water purification pool 1 is 3-5m long, 0.5-1.2m wide, 1-2m deep, and the water level is maintained at 0.8-1.0m; the water inlet end 5 of the mountain spring water purification pool is connected to the upstream water diversion of the stream, and the water outlet of the mountain spring water purif...

Embodiment 2

[0057] The method for training giant salamanders in the training facility described in embodiment 1 may further comprise the steps:

[0058] (1) Newly built training facilities need to be soaked in clean water for 3 months to ensure that the water quality meets the water quality requirements for giant salamander farming; the water temperature of the training facilities is controlled at 16-24°C, and the water quality should meet the following conditions: dissolved oxygen ≥ 3mg / L, pH value: 6.2 ~7, the water is clear and not turbid;

[0059] (2) Select giant salamander seedlings, choose artificially cultured giant salamander seedlings with strong physique, no injuries, and consistent specifications. From July to July, the cultivation process is 1.5 to 2 months;

[0060] (3) The giant salamander seedlings are put into the pond, first soak the giant salamander seedlings with 4% salt solution for 30min disinfection; then put them into the culture pond, the stocking density is 1~2 ...

Abstract

The invention discloses a training facility for increasing the field viability of andrias davidianus. The training facility is characterized by comprising a mountain spring water purifying pool, andrias davidianus culturing pools, a training pool and a forage fish culturing pool, wherein the mountain spring water purifying pool, the andrias davidianus culturing pools, the training pool and the forage fish culturing pool are provided with water inlet ends and water outlet ends; the water inlet end of the mountain spring water purifying pool is connected with upstream river water, and the wateroutlets of the mountain spring water purifying pool are connected with the water inlet ends of the andrias davidianus culturing pools; the water outlet ends of the andrias davidianus culturing pools are connected with the water inlets of the training pool; the water outlet end of the training pool is connected with the water inlet end of the forage fish culturing pool; the water outlet end of theforage fish culturing pool is connected with an external drainage ditch. The invention also provides a method for training and culturing the andrias davidianus by utilizing the training facility. Through artificial training, the initiative predation capability of the andrias davidianus can be strengthened, andrias davidianus fries which can adapt to a field natural environment and have strong bodies, strong swimming ability, operation resistance and strong initiative predation capability can be cultured under an artificial condition, and a good release effect can be finally realized.

Description

technical field [0001] The invention belongs to the technical field of aquatic resource conservation, and in particular relates to a training facility for improving the field viability of cultured giant salamanders. The invention also relates to a method for training and cultivating giant salamanders in the facility. Background technique [0002] Giant salamander (Andrias davidianus), commonly known as giant salamander, belongs to the class Amphibian, order Caudata, family Cryptobrachidae, and genus Andrias. List of protected animals and included in Appendix I of the CITES Convention. Giant salamanders inhabit mountain streams, and live in caves with clear water, low sand content, turbulent water flow, and return water. Adult individuals generally live alone in deep water areas, while juvenile salamanders gather and live in shallow crevices. They are photophobic, hide in the nest during the day, and are relatively active at night, often coming out of the cave to look for ...
