How to divide male and female 5, how to divide male and female Fushou snails

It should be hermaphroditism, because I caught one and kept it in the fish tank, and after a while it lay eggs, and after a while, it lay eggs, and it has been spawned three times, and it can hatch, the first time I had no experience and thought it was an egg, and I fed the fish directly, and the second time, I knew that it was the egg of the Fushou snail, so I deliberately put it, and then it hatched out, but it was all eaten by the fish, and this time I put it in another fish tank.

Hermaphrodites, but one cannot reproduce on its own.

Fushou snail is a dioecious, in vivo fertilization, in vitro development of oviparous animals. March and November are the breeding season of Fushou snails, of which May and August are the peak breeding season, and the suitable water temperature is 18 30. One fertilization can lay eggs several times, and eggs begin to lay 3 to 5 days after mating, and at night the female snail climbs to the walls of the pool, wooden stakes, and the stems and leaves of aquatic plants 15 to 40 cm above the water surface to lay eggs.

Oval, pink, about 2 mm in diameter. The eggs are adhered to each other into lumps, one egg is laid at a time, 200 1000 eggs, 20 40 eggs can be laid a year, and the number of eggs laid is 35000.

There are 3 generations of young snails in Guangzhou, the first generation of young snails grows for 93 days and begins to lay eggs, the egg period is 9 days, and the second generation of young snails is hatched for 102 days, with an average daily temperature and relative humidity of 88%, and the second generation of snails grows for 63 days and lays eggs, and the egg period is 11 days, that is, the three generations of young snails are hatched, and the duration is 74 days, with an average daily temperature and a relative humidity of 87%. The three generations of snails grew to the end of March of the following year, a total of 189 days, and they were still young snails, with an average daily temperature and relative humidity of 78%, and the overlapping of each generation of snails. The age of the snail is 20 80 days, each snail is 10 days, the first generation gains weight, the second generation, the third generation of each female snail breeds an average of 3050 young snails, the hatching rate is, the second generation of each female snail breeds an average of 1068 young snails, hatching rate, 1 female snail after 1 year and two generations of a total of more than 10,000 young snails, the fecundity is very strong.

The difference between Fushou snail and field snail is as followsThe difference between Fushou snail and field snailFirst, the appearance is differentGenerally, the individual of the snail is at least 1 times larger than the snail, some people will say, what if you encounter a large snail and a medium snail, they are the same size? The appearance of the snail is characterized by a short and flat snail, although it is larger, it is more like a multi-point that grows horizontally, that is, the top of the snail is not so sharp, and the shape of the snail is more slender and the top is more pointed.

Second, the color is differentFushou snail is also called ** snail, so the shell color of Fushou snail is lighter, light yellow and black shell, not only the shell color is lighter, but the meat inside is also white and yellowish, and the meat of some Fushou snails is still black and gradient white. The color of the shell of the snail is dark brown, and its flesh is also dark brown.

Third, the hardness of the shell is differentThe shell of the snail is relatively brittle compared to the snail, and generally you gently throw it into the cement floor, gently knock its shell with a stone, and it can be cracked, or you can crush it if you step on it with your foot. The texture of the snail shell is much harder, and if you don't wear iron shoes, you can hardly break it. If one day you go out for supper and accidentally drop a snail on the ground, and instantly find that its shell is broken, then congratulations, this must be a snail, not a snail.

The shell of the snail is similar to that of the snail, the shell is right-handed, the texture is hard, the color is yellow or black-brown, and there are many fine longitudinal stripes on the surface.

And the head of the snail has two pairs of antennae, the anterior antennae are shorter, the posterior antennae are longer, and the base each has an eye, and the snail is suitable for growing in an environment with fresh water quality, likes sweet food, and mainly feeds on duckweed, vegetables, melons and fruits.

The appearance of the snail shell is similar to that of the snail.

It has a spiral shell, the color varies with the environment and the age of the snail, it is shiny and has several fine longitudinal lines, and the head and gastropods are protruding when crawling. The head has 2 pairs of antennae, the anterior antennae are short, the posterior antennae are long, and the posterior antennae have an eye on each lateral side of the base. There is a thick lung suction tube on the left side of the snail.

The adult shell is thick, the shell is 7 cm high, the young shell is thin, the suture line of the shell is sunken in a shallow groove, and the shell umbilicus is deep and wide.

Oval, 2 mm in diameter, the eggs are pink or bright red at the beginning, the surface of the eggs has an inconspicuous layer of white powder, in May-June, after 5 days it becomes grayish-white or brown, at this time the eggs have hatched into young snails. The egg masses are oval, different sizes, the eggs are arranged neatly, the egg layer is not easy to fall off, bright red, the small egg masses are only dozens of grains, and the large egg masses can reach more than 1,000 grains.

Habits. Fushou snail has a wide range of food, is an omnivorous snail based on plant bait, mainly eats duckweed, vegetables, melons and fruits, etc., especially likes to eat sweet food, but also loves to eat animal carrion in the water. When there is no more food, they eat tiny substances floating on the surface of the water (the body turns upside down and feeds on the object with foot movement).

Although the snail is an aquatic mollusc species, it can be buried in moist mud for 6-8 months during the dry season. In the event of a flash flood or irrigation, they can become active again. The respirators of adult snails can reach up to 5-10 cm long or longer.

<> Fushou snail is dioecious and can reach sexual maturity in just 2-3 months after laying eggs. The female and male snails twist and let the male couple together for mating, which usually takes 2 to 5 hours. If there is a touch disturbance during mating, it will stop immediately.

The female snail often lays eggs at night, crawls out of the surface of the water in Xinzheng during spawning, and lays crimson egg masses on the plants and stakes on the pond wall or water surface, and the ovulation time is as long as 1 hour to 2 hours. Glide.
