Breeding habits and artificial hatching methods of snakes
1. The reproductive habits of snakes snakes are dioecious, fertilized, oviparous, or oviparous animals. The sexual organs matured 2-3 years after hatching. There is no obvious difference between male and female snakes in appearance, but it is easier to distinguish between similar snakes of the same size, the female snakes generally have a smaller head and a short fat tail, while the male snakes have a larger head and a slender tail. When squeezing the back end of the anal foramen with two fingers, the female snake's anal foramen appears flat and concave, and the male snake's anal foramen will reveal two "semi-penises", that is, a pair of copulators, which is an accurate identification of female and male snakes.

Parent fish cultivation techniques of four major domestic fish in spring
Spring is an important period for gonadal maturation of parent fish. From the beginning of spring to spawning, a large amount of nutrients in parent fish are transferred to gonadal development, so the cultivation of parent fish should be strengthened in spring to meet the needs of gonadal development and promote timely maturation and smooth spawning. The cultivation techniques are as follows: 1. Divide the pond ahead of time. Adjusting stocking density and breed matching is the first condition to cultivate good parent fish. The area of the pond separated by the parent fish should be 2000 square meters and 2600 square meters. Drain the pond water before dividing the pond to remove wild miscellaneous fish, clams and enemy pests, and at the same time remove some of the pollution.

Cultivation of parent Fish of Autumn Grass
The sex cells of grass carp are in the period of growth and development in autumn and winter. the quality of feeding and management at this stage directly affects the gonadal maturation, the effect of spawning in the second year, and the fertilization rate and hatching rate of fish eggs. For this reason, the cultivation of grass carp should be grasped from the following points in autumn and winter. 1. Prepare the fish pond. To cultivate grass parent fish ponds, it is required to be close to the spawning pond and have good water sources. The area of the fish pond is generally 340 mu and the water depth is 1.5 meters. Before parent fish are released, fish ponds should be cleaned, ridges should be repaired, weeds should be removed, and drugs such as quicklime or bleach should be used.

Key points of cultivation techniques of parent fish in winter
The cultivation of parent fish can be divided into postpartum nursing, autumn cultivation, winter cultivation and spring cultivation. Due to the low temperature in winter, the activities of parent fish are reduced, the feeding ability is weak, and fish diseases are easy to occur. If it is poorly managed, it will have a great impact on artificial hatching, fry production, adult fish culture and other production links in the coming year. The main technical points for the cultivation of parent fish in winter are as follows: first, the selection of parent fish pond requires sufficient water source, flat bottom, shelter from the wind and sun, water conservation and heat preservation, with an area of 10 Mel and 15 mu. two
