Breeding method of water snake 1. Water source. Water snake, as its name implies, is a snake with aquatic or semi-aquatic habits. Therefore, the arrangement of water sources in aquaculture is a key. In the season when water snakes are active, keep the water source adequate and clean. In midsummer, the pond should be thoroughly cleaned and descaled every 7 ~ 15 days, so as to avoid enteritis caused by water snakes drinking unclean water in despair and causing undue trouble.
Second, the source of food. Besides eating all kinds of freshwater fish and loach, water snakes especially like eel and frog. Water snakes should be fed on time according to their easy catching season or fattening needs, and the feeding types should be diversified as much as possible to meet their physical growth needs. Most water snakes have a big appetite, every 4? Feed once every 5 days, and the average strip weight is about 100? A water snake of about 200 grams can swallow 1 every time? 2 small miscellaneous fish, more than 3? Four articles. In addition, the water snake is particularly courageous, and if someone is around when swallowing, it will not affect eating. This snake, like other snakes, has the habit of lying still after eating, so don't disturb it too much at this time, otherwise it will spit out the food swallowed in its stomach, which will inevitably delay the next time to eat and reduce the amount of food it should eat, which is extremely unfavorable to the growth of water snakes. It is necessary to artificially reduce the number of times people enter the stadium to wait and see or refuse to visit strangers.
Third, disinfection. The culture density of artificially cultured water snakes should be per square meter 12? There are about 15 pieces, and the three-dimensional culture can be appropriately larger, but not more than 2 times. Under normal feeding conditions, it should be disinfected twice a month. Three times, spray and splash water, and it is best to choose early morning or evening for disinfection. Because most water snakes like to move during the day, they especially like to get together and bask in the sun after eating. When the outside temperature reaches above 32℃, I especially like to soak in the water in groups, and I can stay in the water for a long time as long as my head is slightly exposed. Therefore, during disinfection, it is necessary to avoid the peak period of water snakes' activities outside, so as to avoid undue interference and shock.
Living in a suitable environment, water snakes rarely get sick and die, which is the lowest mortality rate among artificially cultured snakes at present, which is also the main reason why they can reproduce spontaneously in the wild. Therefore, it is suggested that the original snake farm (household) may wish to switch to raising snakes and occupy one market as soon as possible.
Morphological characteristics of water snakes Most species are thick, with black spots on the body surface or stripes on the back, and scales are ridged. Semi-aquatic and non-toxic, it preys on fish and amphibians by biting. American water snakes are common in or near water. They are viviparous and can give birth to 30? 75 young snakes. European water snakes are less dependent on water and lay eggs. All species in this genus have a bad temper. In self-defense, in addition to head swelling and biting opponents, they also release an unpleasant secretion from anal glands. There are 1 1 species of water snakes in the east of the Rocky Mountains in North America, and the representative species is Natrix sipedon, which is widely distributed and has different common names for each subspecies. Brown body with stripes or banded spots, about 90 cm (35 inches) long; Because of its similar appearance to poisonous aquatic fish-eating snakes, it is often called fish-eating snakes. Common European water snake (n. swimming snake, sometimes called tropical swimming snake; Grass snakes are distributed in western Europe (including the British Isles) and from North Africa to Central Asia. Dark green to black, usually with small black spots on the back, short lines on both sides of the body, white, yellow or orange spots on both sides of the head or neck; Some water snakes are close to 1 .8m (6ft) in length, but the average length is less than1m.. N. tesselata from Europe to Central Asia lives in water and feeds on fish. N. piscator in India is named after its scales on the back have obvious backs. Most grass snakes (tiger snakes) from East Asia to Japan are dark green or blue.
