How to raise river mussels in the north Field snails and turtles, I am at the junction of Shaanxi an

Shaanxi-Gansu junction. It depends on whether it is fresh water or salt water.

It should be suitable for the environment in which they are grown.

River mussels. Chinese species Dorsal horn toothless mussel (Awoodiana woodiana) shell up to 200 mm long, angular-oval in shape, two inflated shells, posterior mussel.

The dorsal margin has wings, and the dorsal part has three costal veins originating from the top of the shell, and the lowest costal vein is located on the midline of the shell. It mostly inhabits silt-bottomed, slow-flowing and still water waters, and is found in rivers, lakes, reservoirs and ponds. Dioecism.

In the dorsal horn toothless mussel in Jiangsu, the gonads matured in March, and the mature eggs were fertilized and developed in the female outer gills, and the hook intermediate larvae matured and excreted from the body in April and May, parasitic on the fish body, and after developing into juvenile mussels, they sank to the bottom of the water to live. It is a freshwater pearl breeding [1][2] mussel, but the quality of the pearl is inferior. Meat for consumption.

Shells are used as traditional Chinese medicines.

Snails Snails are mollusks. The body is divided into three parts: the head, the feet, and the internal organs, and the head has a mouth, eyes, antennae, and other sensory organs. There is an outer shell on the outside of the body.

The foot muscles of the snail are well developed and are located on the ventral surface of the body. The diaphragm attached to the soles of the feet is called a snail, which is like a round lid, and when it encounters an accident or needs to rest, the snail shrinks its body in the shell, and contracts through the muscles of the foot to cover the shell tightly. The snail is edible, and the edible part is mainly its fleshy sufficiency.

Snails are distributed in most parts of the country. It can be caught in summer and autumn. Chinese round snails are commonly found in fresh water.

Turtles. Turtles are semi-aquatic and semi-terrestrial reptiles. It mainly inhabits rivers, lakes, reservoirs, ponds and other waters.

This is a taboo for raising turtles, because there are very parasites on the snails, and the baby turtles may eat them by mistake and die due to parasitic diseases.

No, the snail is the food of the tortoise.

Let's change turtle breeding.

Alien species are about to overflow.

It's better not to, it may be eaten.

And the living environment is not the same.

If you don't have enough space, you don't need it.

No, because the Brazilian tortoise is an invasive alien species.

First of all, you have to know whether Wang Ba eats snails or not.

Eat it, but you have to break it up and get the meat out before you can feed it.

You may not be able to eat it with a shell.

There may be parasites when you catch it, so be careful.

Don't eat. Domestic turtles like this are just fed pet feed.

Field snails are dioecious animals that need to be mated to reproduce offspring. In addition, the snail is an ovoviviparous animal with a unique reproductive mode, and the embryonic development and young snail development of the snail are completed in the mother's body. From the fertilized egg to the birth of the snail, it takes about one year to conceive in the mother's body.

Field snails are laid in batches, and they begin to breed in March and April every year, and at the same time as producing snails, female and male snails mate and fertilize, and at the same time give birth to snails to be produced in the next year in the mother's body. A female snail produces about 100 and 150 baby snails throughout the year.

River mussels and snails will definitely starve to death if they do not eat. Those in the wild will look for food on their own, and those in captivity will be fed food.

1.River mussels feed on organic matter particles, rotifers, flagellates, algae, small crustaceans, etc., and feed on filter-feeding algae, and can also feed bloodworms and other foods. There is a crystal rod between the gastrointestinal tract, which is a slender rod-like object, the front end is thicker, and the top end has a large morphological variation, showing a thin tip, swelling, hook-shaped, coiled, etc.

The crystal rod is located in the intestine, and its anterior end protrudes into the stomach, where it meets the lower part of the gastric shield. The rods may be stored food, and the mussels disappear after 24 hours in the absence of food, refeeding, and re-exist after a few days.

2.The snail breeding pond first applies some manure to cultivate plankton to provide bait for the snails. The amount of fertilizer depends on the fat and thinness of the bottom of the snail pond.

After the snails are put into the pond, they are fed with vegetables, rice bran, fish offal, vegetable cakes, bean cakes, etc. Green horn and fish offal should be chopped and mixed with rice bran and other feeds. Vegetable cakes, bean cakes, etc. should be soaked and softened so that they can be eaten by snails.

The amount of feeding depends on the feeding situation of the snails, generally calculated according to 1%-3% of the total amount of snails, and is fed every 2-3 days. The feeding time is every morning, the position of the bait does not have to be fixed, and the feed is put every other day. When the temperature is below 15 or above 30, there is no need to cast bait.

It shouldn't be that easy. It's very vigorous. Besides, as long as there is water, there are microorganisms, so I am not afraid

Yes, but it's a little longer.
