What are the characteristics of the breeding habits of the stone frog?
The frog, also known as the field chicken, has always been called the guardian of crops. Frogs have always lived in rice paddies catching pests, but as the nutritional value of frogs and their benefits have become known to more and more people in recent years, wild frogs in rice paddies have become fewer ⟦4 <p>The frog, also known as the field chicken, has always been called the “guardian of crops”. Frogs have always lived in rice paddies catching pests, but as the nutritional value of frogs and their benefits have become known to more and more people in recent years, wild frogs in rice paddies have become fewer and fewer.</p><p></p><p><strong>A brief analysis of the breeding habits of the stone frog</strong></p><p>Spring and autumn are the seasons when the stone frog is most active, eats the most, and grows the fastest. May to September is the breeding season of the stone frog, and May to June is the peak spawning period. During the peak breeding period, the stone frog is highly active and exhibits behaviors such as calling and amplexus. The stone frog mates and lays eggs 3 times each year. 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. In a suitable environment, after 40-70 days of growth and development, they metamorphose into young frogs.</p><p></p><p><strong>Difficulties in frog farming </strong></p><p>1. How to solve the issue of breeding frogs and seedlings for frog farming </p><p>Answer: Because temperatures vary from place to place, the time when frogs emerge from their burrows also differs. Roughly starting in March, frogs begin to emerge, 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”. </p><p>2. The focus of frog farming </p><p>Answer: Troops and horses may not move, but food and forage go first. Having sufficient food is the prerequisite for frog growth, so the food factor is the most important, followed by routine disease prevention, predator prevention, and the hygiene of the growing environment. </p><p>3. Problems with frog farming reproduction and growth </p><p>Answer: Frogs generally lay about 1000-2500 eggs each time. From egg to tadpole takes about a one-week incubation period, from tadpole to young frog takes 2.5-3 months, and from young frog to marketable frog takes 4-5 months. The length of time depends on an individual's farming techniques, the farming temperature, and whether the nutritional content of the feed is high or low! </p><p>Based on summary and analysis, frog farming ponds should be small rather than large. Only when they are small are they convenient to manage, and only then is 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-surface farming, with water depth between 5-30 cm! </p><p></p><p>4. Relevant certificates for frog farming </p><p>Answer: You need to apply for a domestication and breeding permit, a business utilization permit, a transport permit, etc. But we emphasize that frog farming is difficult, so do not blindly invest funds. If you truly want to farm them, 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 or not to farm them yourself. Because it is a trial farming stage, with no 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 techniques, the certificates are merely decorations. As long as you have mastered the techniques and have evidence to show the relevant departments, the government will certainly support this project. Overall, the most important thing in frog farming is technique, not certificates. Having certificates does not mean having technique! </p><p>5. Choosing food for frogs </p><p>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 the growth cycles of earthworms and yellow mealworms are relatively long, ranging from 2-3 months, so from the perspective of time alone, it is unrealistic. Moreover, from the analysis of the site for earthworm farming and the cost of yellow mealworm farming, it is also unrealistic. In the farming industry, centering on saving costs, maggots are therefore the most suitable to be farmed as feed. </p><p></p><p><strong>Frog farming cycle </strong></p><p>When young, frogs can only live in water. After growing up, they can also live on land. Frogs use their lungs to breathe, but they can also absorb oxygen from the air through their moist skin. The various pigment cells in their skin also expand or contract with humidity and temperature, causing changes in the shade of their skin color. Frogs usually inhabit rice paddies, ponds, ditches, or grassy areas along riverbanks, and sometimes lurk in the water. They generally hunt at night. </p><p>It is reported that from egg to frog takes about more than one month, and they can reach adulthood in 2 months, which is related to environmental factors such as temperature. Frogs in nature generally live about 5 years, while farmed ones can live about 13 years. However, the lifespans of various frogs differ; generally speaking, the larger the body size, the longer the lifespan. Bullfrogs can live 16 years. </p><p></p><p><strong>The uses of frogs </strong></p><p>1. Nutritional components </p><p>Frog meat is tender, low in fat, and low in sugar, and is rich in protein, carbohydrates, calcium, phosphorus, iron, vitamin A, B-group vitamins, vitamin C, and various hormones. </p><p>2. Medicinal value </p><p>The frog is also a medicinal animal that combines food, health products, and medicine in one. As food, it is an excellent green food. In the Ming dynasty, Li Shizhen's “Compendium of Materia Medica” records: “Southerners eat it and call it field chicken, saying its meat tastes like chicken.” “Eating it is extremely delicious.” As medicine, it is a dietary therapy health product and medicine. 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 adult frog's gallbladder, liver, brain, and skin can all be used as medicine. The larval tadpole has the effect of prolonging life.</p><p></p><p>Precisely because the market demand for frogs is relatively large, wild frogs are far from able to meet people's needs, so frog farming has been quite popular in recent years. However, when farming frogs, you must first fully understand the frogs' living habits, so as to improve the success rate of frog farming.</p>
