Description

Technical Field

[0001] The invention relates to the field of salamander breeding, and in particular to a device for breeding young salamanders. Background Art

[0002] Hynobius anjiensis belongs to the genus Hynobius (Hynobiusamjiensis), Caudata, Amphibia. The male (male anus is fissured longitudinally, with a small papilla in the center of the front edge) is 153–166 mm long, and the female is about 166 mm long. The head is oval and relatively flat, slightly longer than the head width, and the trunk is sturdy and slightly flat. There are 13 rib grooves on the sides of the body, the body surface is smooth, and there is a longitudinal skin groove from the eyes to the neck fold. The back of the body is dark brown or brown-black, the abdomen is gray-brown, and there are no spots. There are 4 fingers and 5 toes. The tail is flattened laterally, and the tail fin fold is obvious. This species is currently known to be distributed only in the alpine swamp areas of Longwang Mountain in Anji, Qingliangfeng National Nature Reserve in Anhui, and Baizhangling in Lin'an. As a species endemic to China, the Anji Hypsilophodon davidianus is assessed as a critically endangered (CR) species on the China Red List of Vertebrates due to its extremely limited distribution range, small and declining population, and continued threats to its habitat. It was listed as a national first-class protected animal on the "National Key Protected Wildlife List" in March 2021.

[0003] Due to the special living and breeding habits of Anji Hynobius, cannibalism among young salamanders is another important factor affecting the population of Anji Hynobius. The survival rate of young salamanders in the wild is less than 1% due to cannibalism. Indoor feeding observation shows that the survival rate of young salamanders is only about 1%-2% when fed or underfed, and the rest are all eaten by their companions. So far, there has been no systematic research on the artificial breeding of Anji Hynobius, so there is an urgent need for an experimental plan to achieve indoor breeding of Anji Hynobius.

[0004] Therefore, we propose a device for breeding larvae of Hynomaria davidiana. Summary of the invention
