Giant salamander breeding technology, natural reproduction success rate of giant salamander

Summary. Hello dear, in the wild, giant salamanders generally have a low reproductive success rate. According to incomplete statistics, the reproductive success rate of giant salamanders in the wild environment is 5%!

Around. And under artificial breeding conditions, the reproductive success rate of giant salamanders can be increased to 50%!to (missing).

For example, data released by the National Forestry and Grassland Administration in 2019 showed that in the artificial breeding of giant salamanders in Zhangjiajie City, Hunan Province, the reproductive success rate was as high as 80%!Above. It is important to note that the giant salamander is a slow-growing animal with a long reproductive cycle, generally taking 3-5 years to reach sexual maturity.

Therefore, the breeding of giant salamanders requires long-term patience and commitment. Hope it helps.

Can you tell us more about that?

Chinese salamander. Paramesotriton: 1 genus of the salamanderidae family.

Body length 100 155 mm. The head is flattened, and the vomer is dentition-shaped. The trunk is cylindrical, and the limbs are thin and long.

Tail flattened. **Rough. There are glandular ridges on the cephalad side, mid-ridges on the dorsal side, and the dorsal scrofula is evenly dispersed, slightly larger and conspicuous along the sides of the body.

The ventral surface is marked with orange-red spots. There are three species in China: the Chinese newt, which is mainly distributed in Anhui, Zhejiang, Fujian, Guangdong and Guangxi; The tail spotted newt is distributed in the eastern part of Guizhou, and the Guangxi newt is distributed in the Guangxi Zhuang Autonomous Region.

This genus inhabits and near the backwaters of mountain rapids with dense vegetation and humid environments. It is often hidden under the rocks in the stream or in the weeds next to the stream, as well as in the damp soil holes and stone crevices covered by rotting leaves. It feeds on a variety of insects such as adults of Coleoptera and larvae of Lepidoptera.

Identification features The total length is 83 155 mm, and the tail is shorter than the head and body length. The back is uniform corner black; The ventral surface is light brown with dark spots. The head is longer than the width of the head, and the snout is rounded; dorsal lateral position of the eyes, round pupils; The nostrils are slightly close to the snout, and the nasal distance is slightly greater than or equal to the eye distance; without labial folds, with throat folds; Vomer dentition presents"v"shaped, the angle of intersection of the inner and outer branches slightly extends beyond the anterior margin of the inner nostrils, and the inner branches are close but not connected at the posterior end.

The trunk is stubby and slightly cylindrical, and the lateral costal sulcus is 10 12. The limbs are long, the fingers meet when the body is facing each other, the four fingers and five toes, relatively flattened, free and webbed, and the palmoplantar fingers and toes are not. The base of the tail is slightly rounded, posteriorly flattened, and the end is blade-shaped.

Habits Inhabit hills or low mountains. In the non-breeding season, they live on land, usually hiding under damp loose soil, decaying leaves or stones, and can often be dug out from under cultivated land or rotting branches and leaves. Go to the surface on rainy days or in the evening to feed on earthworms, insects or other arthropods and their larvae.

Spawning begins at the end of November to mid-February in Xiaoshan, Zhejiang, and begins in early January in Yiwu, Zhejiang, and can continue until January. The eggs are laid in a small pond with a depth of several centimeters and many weeds, the egg capsule is 150 170 mm long, the middle diameter is 23 27 mm, the paired egg capsules are adhered to the aquatic plants or underwater stones with the stalk at the base end, each egg capsule contains 33 66 eggs, and the egg diameter is mm. The incubation period is about 40 days, and the larvae eat each other.

The first thing that must be noted in complete water is that you cannot use tap water directly.

Tap water should be dried for at least 1 day Mineral water can also be kept clean The water quality must be kept clean If you are too lazy to change the water, press a filter Food likes live food Bloodworms, snakes, earthworms and the like It is best to take shelter on land Let them have a sense of security.

There are also some in my hometown that I can't raise when I take them home.

The small salamander is about 5 to 9 cm long, similar in shape to the giant salamander, with a long and flattened body, well-developed limbs, short limbs, 4 toes on the forelimbs and 5 toes on the hind limbs, and a short and sideways flattened tail, black or tan on the back, light on the ventral surface, **smooth without wart, trunk cylindrical, slightly flattened, and rib sulcus on the side of the body; have lungs; The base of the tail is rounded and gradually flattened laterally backwards. The head is small, the head is flattened and oval; The tongue is large and the teeth are V-shaped.

Terrestrial salamanders, pseudosalamanders, arctic salamanders and clawed salamanders mainly live in the damp grass and burrows in the forest at an altitude of 120 to 1800 meters. During the breeding season, they enter the stream to lay eggs under the rocks or between the branches and leaves of plants; Terrestrial life after the breeding period; It feeds on a variety of insects, worms, earthworms, slugs, myriapods and other small animals.

The aquatic-based fat salamander, northern salamander, mountain stream salamander and paratoed salamander mostly inhabit the cold mountain streams with clear water quality at an altitude of 1000 to 4400 meters, and still inhabit in the water or ashore in a humid environment for a short time after the breeding period, and are not far from the water source. feed on small aquatic animals (shrimp, insects and larvae, slugs); The tail is very sideways and is adapted to feeding and swimming in water. Small salamanders are a relatively primitive group of the order Certaus. Some genera and species of the small salamanderidae family can be used medicinally.

The skin, flesh, gall, fat, heart, liver, brain, etc. of the hedgehog have medicinal value because they prey on a large number of harmful insects and are beneficial animals.

dorsal and lateral body covered with spines, head, tail, and ventral coat; The mouth is pointed and long, and the tail is short; The forefoot has 5 toes, tiptoeing, and a few species have 4 toes on the forefoot; 36 44 teeth, all with sharp tooth tips, suitable for insectivory; When frightened, the spines on the whole body are erect and rolled up like a ball of thorns, and the head and four legs are not visible. Hedgehogs are belonging to the order Hedgehogs in the order of mammals. The most common species of hedgehog is the common hedgehog with the scientific name "European hedgehog", which is widely distributed in Europe, northern Asia, and is also widely distributed in northern China and the Yangtze River Basin.
