Experience of feeding and management in the initial growth stage of cultured stone frog tadpoles

Stone silicon I think many people have eaten it, stone silicon has a high nutritional value, and the taste is also very delicious, so many people like to eat stone silicon in life. With the increasing demand for stone silicon, more and more people cultivate stone silicon.

Experience of feeding and management in the initial growth stage of cultured stone frog tadpoles

Feeding and management of stone frog tadpoles at the initial stage of growth tadpoles live on yolk within 3 days of hatching and start foraging 3 days later. Feed 1 egg yolk or 1-1.5 kg soybean milk per ten thousand tadpoles and properly add some natural plankton in the water, such as water fleas and algae, once a day in the evening. When feeding, the bait can be sprinkled directly on the surface of the water. It is required that the fine water is always flowing, fresh and pollution-free, the water temperature is kept at 20-29C, and the pH value is 6Mui 8. The water depth is 10ml 15cm. Change the pool water once a day. Water floating lotus and other aquatic plants are released in the pond to avoid direct sunlight on the pool water. Insist on patrolling the pool in the morning and evening, often remove wild frogs, water snakes, wild miscellaneous fish and birds and other enemies, and add new water at any time to protect the safe growth of tadpoles. After 10 days of growth and development, the tadpole can grow to 1.5 cm in length.

The life habit of stone frog

Stone frog belongs to running water life type. It is often inhabited in the stream with slow flow in the mountain area or in the puddle of the stream, where both sides of the stream are rich in vegetation. They rarely leave the water, and their body color often adapts to their living environment. The second sexual characteristics develop towards a strong embrace, with large males, extremely strong forelimbs and well-developed marital thorns, which have a lot to do with reproductive characteristics. when spawning, males and males must lay their eggs in a stream hit by running water. during mating, the male hugs the female forcefully and strengthens the male's fixation with the help of abdominal spines so that they are not washed away by the current.

The stone frog has an internal vocal sac, the sound is low and turbid, and the male call is "goo goo". The female responds with a "click" sound. Stone frogs have the habit of living in groups and foraging at night, often several or dozens of them live together. In a quiet and suitable environment, stone frogs also come out to look for food during the day, and the peak period of activity is at night. Stone frog is good at jumping and climbing, usually the activity is weak and stable, in the peak period of breeding, frequent activities, with singing and hugging and other behaviors.

Stone frogs like to eat active animals and generally do not eat dead or immobile food. in the natural state, stone frogs eat a wide range of food, in addition to insects, centipedes, spiders, horse land, snails, snails, clams, earthworms, shrimp, but also prey on crabs, miscellaneous fish, Loach, young snakes and small birds. Stone frogs in different areas have different feeding habits due to the different bait that the environment can provide. Stone frogs generally swallow 9% of their body weight in nature, sometimes up to 12.8%.

Construction of Stone Frog Pond

Wild stone frogs perennially inhabit shady mountain streams and ditches or near stone caves with waterfalls. Their living environment requires adequate water flow, cool, humid, fresh water quality, and like to live in stone caves. Growth and development, breeding and reproduction have been in the wild for a long time. Great changes have taken place in the living environment of artificially domesticated stone frogs from wild to domesticated. When stone frogs are raised artificially, the reasonable design of the frog pond must be adopted so that the frog pond should not only be similar to the natural environment, but also be convenient for manual management.

1. The choice of breeding site: the quality of the environment directly affects the growth, development and reproduction of stone frog, and the frog pond is not restricted by the location. generally speaking, the breeding site should be selected in a place with good water quality, convenient drainage and irrigation, quiet environment, warm winter and cool summer, no drought, no waterlogging, convenient management, anti-escape and anti-damage. Frog ponds can be built indoors or outdoors, indoor requires ventilation, cool, no direct sunlight, outdoor can be set up Arbor, under the construction of frog ponds, simply built indoors, courtyards or outdoor ponds, are good living places for stone frogs.

2. specification requirements of frog ponds: artificial breeding stone frogs are generally intensive breeding, and attention should be paid to conforming to the living habits of frogs as far as possible, providing water, land, stone caves, feeding and other conditions, so as to create a good living environment and facilitate feeding and management.

The breeding prospect of stone frog

The whole technology of artificial breeding stone frog has just matured in recent years, and now it is in its infancy in China. Coupled with the limitations of provenance, technical popularization and culture conditions, it is difficult to form a certain production scale in recent years, let alone a mass influx. Supply exceeds demand. With the increase of market demand and the increasing depletion of wild resources, the contradiction that demand exceeds supply increases day by day.

For this reason, better economic benefits can be obtained by introducing and mastering mature artificial culture technology, forming culture scale as soon as possible, seizing the opportunity and taking the first step.

In order to cultivate stone silicon, we must first build a decent stone silicon field. The construction of stone silicon field must be fastidious in terms of site selection and construction. The growth environment and conditions required by different stages of stone silicon are different.
