A brief Analysis of the breeding habits of Stone Frog

Frogs, also known as frogs, have always been known as "crop guardians". Frogs have always lived in rice fields to catch pests, but as more and more people know the nutritional value and efficacy of frogs in recent years, there are fewer and fewer wild frogs in rice fields.

A brief Analysis of the breeding habits of Stone Frog

Spring and autumn are the seasons with the most frequent activities, the largest food intake and the fastest growth of stone frogs. May-September is the breeding season of stone frogs, and May-June is the peak period of spawning. During the peak breeding period, stone frogs are active frequently and have the behaviors of whining and hugging. Stone frogs mate and lay eggs three times a year. Female frogs lay 500, 000 eggs a year, laying their eggs on the banks of streams hit by running water or attached to rocks in ditches or aquatic plants. During mating, the male hugs the female and strengthens the male's fixation with the help of abdominal spines. The egg diameter is 1.3mi 1.5 mm, and there is a gelatinous membrane outside the egg. After the egg is laid, it absorbs water and expands, which can reach 3 times of the original egg diameter. Many eggs adhere together, in the shape of a cord or string of grapes, about 20 cm long, floating in or attached to objects in the water. Under natural conditions, frog eggs hatch into tadpoles after about 15 days. Tadpoles like to live in the big rocks or gravel piles in the creek pits. In a suitable environment, they become young frogs after 40 li and 70 days of growth and development.

Difficulties in Frog Culture

1. How to solve the problem of frog breeding and frog seedlings

A: due to the different temperatures in different places, the time when frogs come out of the hole is also different. Probably frogs have come out of the hole since March. At that time, they can go to the wild to collect frogs or frog eggs, and there is no need to buy the so-called "species."

2. The center of gravity of frog breeding

A: food comes first before the army moves. Having enough food is the premise for frogs to grow, so food is the most important, followed by disease prevention, prevention of natural enemies, and hygiene of the growing environment.

3. Breeding and growth of frogs

Answer: frogs usually lay about 1000-2500 eggs each time. It takes a week to incubate from eggs to tadpoles, from tadpoles to young frogs, and 4-5 months from young frogs to commercial frogs. The length of time depends on individual breeding skills, breeding temperature and feed nutrients are higher than low!

After summary and analysis, frog culture ponds should be small rather than large, only small to facilitate management, can it be easier to manage frog growth or disease prevention and other problems, soil ponds, cement ponds can be water-to-land ratio at 3:1, or choose whole-surface culture, water depth between 5-30CM!

4. Relevant certificates for frog breeding

Answer: need to apply for domestication and breeding license, operation and utilization license, transport license, and so on. However, we emphasize that frog farming is difficult, so do not invest money blindly. If you really want to raise frogs, you must go through this stage of trial breeding. The purpose is to accumulate experience and experience the process of frog breeding. Finally, you will consider whether to raise frogs or not. As it is a trial breeding stage, if it is not sold and resold, the relevant departments will not control it very strictly, so you do not need to apply for any certificates, even if you apply for certificates. However, without technology, documents are only equal to decoration. as long as you master the technology and have the evidence to show to the relevant departments, then the government will certainly support this project. generally speaking, the most important thing in frog farming is technology, not documents. Just because you have documents doesn't mean you have technology!

5. The choice of frog food

Answer: at present, the animal feed in the breeding industry includes maggots, earthworms, yellow powder insects, barley insects and so on. Maggots are the most suitable for frog breeding. The analysis shows that the growth cycle of earthworms and yellow powder insects is longer, ranging from 2 to 3 months. Therefore, it is unrealistic to consider only from the point of view of time, and it is also unrealistic to analyze the cost of breeding yellow pink insects in earthworm breeding sites. The breeding industry focuses on cost saving. So maggots are the most suitable for breeding as feed.

Frog culture cycle

Frogs can only live in water when they are young, and can live on land when they grow up. Frogs breathe through their lungs, but they can also draw oxygen from the air through their moist skin. All kinds of pigment cells in its skin will also spread or contract with the humidity and temperature, thus changing the depth of the skin. Frogs usually live in rice fields, ponds, ditches or grass along rivers, and sometimes lurk in the water, usually hunting at night.

It is reported that it takes more than a month to go from egg to frog, and it takes two months to reach adulthood, which is related to environmental factors such as temperature. Frogs in nature generally have a life span of about 5 years, while farmed frogs can live for about 13 years. But all kinds of frogs have their own lifespans. Generally speaking, the bigger the frog, the longer the life span. Bullfrogs can live for 16 years.

The role of frogs

1. Nutritional composition

Frog meat is tender, low in fat, low in sugar, rich in protein, carbohydrates, calcium, phosphorus, iron, vitamin A, B vitamins, vitamin C and a variety of hormones.

2. Medicinal value

Frogs are also medicinal animals that combine food, health products and medicine. Edible, is the best green food. Ming Li Shizhen's Compendium of Materia Medica contains: "people in the south eat it and call it a pheasant, and cloud meat tastes like chicken." "the most beautiful food". For medicinal purposes, it is a diet, health care product and medicine. According to the "Northeast Animal Medicine" records: "Frogs rarely or Yin dry use, can all be used as medicine", has the "diuresis and detumescence, detoxification and cough" effect, can "treat water swelling and asthma cough, measles, menorrhagia and so on." The gallbladder, liver, brain and skin of the adult can be used for medicine. Larval tadpoles have the effect of prolonging life.

Precisely because the market demand for frogs is relatively large, wild frogs are far from being able to meet the needs of people, so frog breeding has been hot in recent years, but when raising frogs, it is necessary to fully understand the living habits of frogs first. only in this way can we improve the success rate of raising frogs.
