A female frog lays 500-1000 eggs per year, depositing them at the streamside washed by flowing water or attaching them to stones in ditches or to aquatic plants. During mating, the male embraces the female and uses the spines on its abdomen to strengthen its grip. The egg diameter is 1.3-1.5 mm. The eggs have a gelatinous membrane outside; after being laid, they absorb water and swell, reaching 2-3 times the original egg diameter. Many eggs stick together, forming strands or clusters like bunches of grapes, with the long ones reaching about 20 cm, floating in the water or attached to objects in the water. Under natural conditions, frog eggs hatch into tadpoles after about 15 days. Tadpoles like to live in large stone crevices or gravel piles in stream pools.

Frogs, also known as paddy frogs, have long been called the “guardians of the crops.” Frogs have always lived in rice paddies catching pests, but as the nutritional value and benefits of frogs have become more widely known in recent years, wild frogs in rice paddies have become fewer and fewer.
A brief analysis of the breeding habits of the stone frog
Spring and autumn are the seasons when stone frogs are most active, eat the most and grow the fastest. May to September is the breeding season for stone frogs, and May to June is the peak spawning period. During the peak breeding period, stone frogs are highly active and display behaviors such as calling and amplexus. Stone frogs mate and lay eggs 3 times a year. A female frog lays 500 to 1000 eggs per year, depositing them at the edge of streams washed by flowing water or attaching them to stones in ditches or to aquatic plants. During mating, the male embraces the female and uses the spines on its abdomen to strengthen its grip. The eggs are 1.3 to 1.5 mm in diameter, with a gelatinous membrane outside; after being laid, the eggs absorb water and swell to 2 to 3 times their original diameter. Many eggs stick together in strings or clusters like bunches of grapes, reaching about 20 cm in length, floating in the water or attached to objects in the water. Under natural conditions, frog eggs hatch into tadpoles after about 15 days. Tadpoles prefer to live in large stone crevices or piles of gravel in stream pools. In a suitable environment, after 40 to 70 days of growth and development, they metamorphose into young frogs.
Difficulties in frog farming
1. How to obtain breeding frogs and seedlings for frog farming
Answer: Because temperatures vary from place to place, frogs emerge from their burrows at different times. They generally begin emerging in March, and at that time you can collect breeding frogs or frog eggs in the wild yourself; there is no need to buy so-called “breeding stock.”
2. The priorities of frog farming
Answer: Food and fodder must be ready before the troops move. Having enough food is the prerequisite for frog growth, so the food issue is the most important, followed by routine disease prevention, prevention of natural enemies, and the hygiene of the growing environment.
3. Breeding and growth issues in frog farming
Answer: Frogs generally lay about 1000-2500 eggs each time. It takes a one-week incubation period from egg to tadpole, 2.5-3 months from tadpole to young frog, and 4-5 months from young frog to market-size frog. The length of time depends on individual farming techniques, farming temperature, and the nutritional content of the feed provided!
Based on summary and analysis, frog farming ponds should be small rather than large. Only when they are small are they convenient to manage, making it easier to manage issues such as frog growth or disease prevention. Earthen ponds and cement ponds are both acceptable, with a water-to-land ratio of 3:1, or you can choose full-water farming, with water depth between 5-30CM!
4. Relevant certificates for frog farming
Answer: You need to apply for a domestication and breeding permit, a business utilization permit, a transport permit, etc. However, we emphasize that frog farming is difficult, so do not invest funds blindly. If you truly want to farm frogs, you must go through a trial farming stage. The purpose is to let yourself accumulate experience and understand the process of frog farming, and only at the end should you consider whether to farm them or not. Because it is a trial farming stage and you are not selling or reselling, the relevant departments will not regulate it very strictly, so there is no need to apply for any certificates. Even if you apply for certificates, without skills the certificates are merely for show. As long as you have mastered the skills and have evidence to show the relevant departments, the government will certainly support this project. Overall, the most important thing in frog farming is skill, not certificates. Having certificates does not mean having skills!
5. Choosing food for frogs
Answer: In the farming industry today, animal feeds include maggots, earthworms, yellow mealworms, superworms, etc. Maggots are the most suitable for frog farming. Analysis shows that earthworms and yellow mealworms have relatively long growth cycles, ranging from 2-3 months, so from the perspective of time alone it is unrealistic, and from the perspective of earthworm farming sites and the cost of yellow mealworm farming it is also unrealistic. In the farming industry, saving costs is the central concern, so maggots are the most suitable feed to be farmed.
Frog farming cycle
When young, frogs can only live in water; after growing up, they can also live on land. Frogs breathe with their lungs, but they can also absorb oxygen from the air through their moist skin. The various pigment cells in their skin also expand or contract according to humidity and temperature, causing changes in the depth of skin color. Frogs usually live in the grass along rice paddies, ponds, ditches or rivers, and sometimes lurk in the water. They generally hunt at night.
It is reported that it takes about a month or more from egg to frog, and they can reach adulthood in 2 months, depending on environmental factors such as temperature. In nature, frogs generally live about 5 years, while farmed ones can live about 13 years. However, the lifespan of various frogs differs; generally speaking, the larger the body size, the longer the lifespan. Bullfrogs can live 16 years.
The uses of frogs
1. Nutritional composition
Frog meat is tender, low in fat and low in sugar, and rich in protein, carbohydrates, calcium, phosphorus, iron, vitamin A, B vitamins, vitamin C and various hormones.
2. Medicinal value
Frogs are also medicinal animals that combine food, health products and medicine in one. As food, they are an excellent green food. In the Ming dynasty, Li Shizhen’s “Compendium of Materia Medica” records: “Southerners eat it and call it paddy frog, saying its meat tastes like chicken.” “Eating it is extremely delicious.” As medicine, they are food-therapy health products and medicines. According to “Northeast Animal Medicines,” “Frogs can be used fresh or dried in the shade, and the whole body can be used as medicine,” with the effects of “promoting diuresis and reducing swelling, detoxifying and relieving cough,” and can “treat edema, asthma and cough, measles, excessive menstruation, etc.” The gallbladder, liver, brain and skin of adult frogs can all be used as medicine. Tadpoles, the larvae, have the effect of prolonging life.
Precisely because the market demand for frogs is relatively large and wild frogs are far from able to meet people’s needs, frog farming has been quite popular in recent years. However, when farming frogs, you must first fully understand the living habits of frogs, so as to improve the success rate of frog farming.
