What kind of food does stone frog eat?

Stone frogs, also known as clams, pheasants, pheasants, stone jelly, flying fish, stone scales, stone toads, stone shrimp toads, stone pit frogs, stone chaos, etc., are amphibious animals of the family Ranidae. With their fresh meat, delicious taste and unique nutrition and medicinal health value, they have been respected by people for a long time. Let's take a look at what food stone frogs eat.

What food does the wild stone frog eat?

The tadpoles, which have just hatched their membranes, are nourished by hatching the yellow sac within 4 to 5 days. When the hatching is consumed, they begin to look for food. The food in the young frog stage is mainly mosquitoes, small insects and insect larvae. At the adult stage, the food range is very wide. 47 adult frogs were dissected and observed. 57 kinds of food were found in the stomach and intestines, such as insects, centipedes, bee spiders, horse land, snails, snail clams, shrimp, crabs, miscellaneous fish, sand dolphins. As well as earthworms, baby snakes, small birds and so on.

What do stone frogs eat in artificial breeding?

The stone frog tadpoles gradually grew up on the energy in the eggs in the first 3 days after breaking the membrane. 10 days after birth, the tadpoles fed on egg yolk and soybean milk, and gradually changed to cooked plant and algae feed after 20 days of age. such as potato stems and leaves, melon fruit leaves, rice and fresh water grass, young frogs mainly feed on small fly maggots, small yellow powder insects, small maggots and other active feeds, and adult frogs mainly eat earthworms, yellow powder insects, fly maggots and so on.

Growth habits of stone frog

1. Living environment: stone frogs often live next to clear puddles in Yinshan or near waterfalls with stone caves, and like to live under damp, quiet, light, near water and cool rock walls. Frogs usually lie at the mouth of the cave or put their head out of the water to breathe and look for food. In case of disturbance, they quickly dive into the cave or under the rock, stone wall or water, and have the habit of looking for food in groups and at night. Usually the activity is weak and stable, and in the peak period of reproduction, the activity is frequent, with the behavior of tweeting and dragging.

2. Feeding habits: stone frogs like to eat active animals and do not eat dead or motionless food. in the natural state, they like to eat live baits such as earthworms, maggots, grasshoppers, ants, Loach, river crab, mole cricket and so on. Taste receptors are well developed and play an important role in their feeding behavior. sensory cells in the retina are particularly sensitive to moving objects, living animals are their feeding objects, and they are not sensitive to dead objects, and there is no feeding behavior. During tadpole feeding, green aquatic algae or soft and delicate animals and plants can be fed with egg yolk, tofu, barley, rice, silkworm pupa powder and other bait and their ingredients. The feeding time is affected by climate and environment.

3. Hibernation habit: stone frog is a cold-blooded animal with no ability to regulate body temperature and heat preservation. Its body temperature varies with external temperature. Generally, the suitable growth temperature is 19-26 ℃. Spring and autumn are the seasons with the most frequent activity, the largest food intake and the fastest growth. April-June and August-September are the best periods for reproduction. When the water temperature exceeds 30 ℃, the skin water evaporation is large, which makes it feel uncomfortable. Feeding activity decreases, when the water temperature drops to 10 ℃, metabolism is very weak, enter hibernation, eyes are closed, do not eat and do not move, rely on fat body to maintain life activities, do not respond to external stimuli, if the water temperature rises to a suitable temperature, it will come out again, the hibernation period is about 4 months, and the weight will be moderately reduced after hibernation.

4. Spawning and reproduction: stone frogs generally begin to be in estrus in April, and male frogs' cries constantly attract female frogs to come and hug each other. When the frogs are right, the female frogs' abdomen are close to each other and embrace each other. The male frogs use their forelimbs with marriage tumors to hold the female frogs under their armpits. The ventral side of the chest is close to the ventral side of the female frogs, and the male frogs begin to ovulate after hugging them. At the same time, the female frogs are stimulated to ovulate, with an ovulation capacity of 1000-3000 eggs each time. Eggs and sperm meet in water to form egg piles after in vitro fertilization, sperm and eggs are fertilized. Eggs are often laid in gentle and shallow water, attached to rocks and aquatic plants, and the glial membrane outside the eggs is thick and sticky. Sometimes connected into a cord or grape string, about 20 cm long, the egg is generally 4 mm in diameter, up to 5 mm in maximum.

5. Abnormal development: frog eggs usually hatch into tadpoles in 8-20 days. Tadpoles like to live in large stone crevices or gravel piles in stream pits. In a suitable environment, frogs generally become young frogs after 60-75 days of growth.
