Rearing and Management Experience for Stone Frog Tadpoles in the Early Growth Stage
Stone frog, I think many people have eaten it. Stone frog has high nutritional value and its taste is very delicious, so many people like to eat stone frog in daily life. As people's demand for stone frog grows, more and more people are breeding stone frog.
Rearing and Management Experience for Stone Frog Tadpoles in the Early Growth Stage
Rearing and management of stone frog tadpoles in the early growth stage: within 3 days after hatching, the tadpoles rely on the yolk for life, and after 3 days they begin to forage. For every 10,000 tadpoles, feed 1 egg yolk or 1-1.5 kg of soybean milk, appropriately add some natural plankton in the water, such as water fleas and algae, and feed once every evening. When feeding, the feed can be scattered directly on the water surface. A gentle constant flow of clean, unpolluted water is required, the water temperature should be kept at 20-29C, and the pH value at 6—8. The water depth is 10—15 cm, and the pond water is changed once a day. Place water hyacinth and other aquatic plants in the pond to avoid direct sunlight on the pond water. Persist in patrolling the pond morning and evening, often remove enemies such as wild frogs, water snakes, wild miscellaneous fish and birds, and add fresh water at any time to protect the tadpoles' safe growth. After 10 days of growth and development, small tadpoles can grow to a body length of 1—1.5 cm.
The Living Habits of the Stone Frog
The stone frog belongs to the running-water life type. It often lives in small streams with relatively slow flow in mountainous areas or in eddy pools of flowing streams, and the vegetation on both banks of the streams is rich. They rarely leave the water area, and their body color often matches their living environment. The secondary sexual characteristics develop toward a strongly embracing mode; the male is larger in body, its forelimbs are extremely thick and strong, and its nuptial spines are also extremely well developed. These characteristics are greatly related to reproductive traits. When spawning, the male and female must lay eggs at the streamside struck by the flowing water; during mating, the male strongly embraces the female and, with the help of the spines on its abdomen, strengthens the male's grip so that they are not scattered by the water flow.
The stone frog has an internal vocal sac, and its call is low, muddy and loud; the male's call is “gu gu gu” and the female responds with a “ka ka ka” sound. The stone frog has the habits of living in groups and foraging at night; often several or dozens of them pile up together and perch in one place. In a quiet and suitable environment, the stone frog also comes out of its burrow to forage during the day, and night is the peak period of activity. The stone frog is good at jumping and climbing; usually its activity is relatively weak and steady, and during the peak breeding period it is frequently active, with behaviors such as calling and amplexus.
The stone frog likes to eat moving animals and generally does not eat dead or motionless food. In the natural state, the stone frog has a wide diet; in addition to insects, centipedes, spiders, millipedes, snails, spiral shells, clams, earthworms and shrimp, it also preys on crabs, miscellaneous fish, loaches, young snakes and small birds. Stone frogs in different regions also differ in diet because the environment provides different bait. In nature, the stone frog generally swallows an amount equal to 9% of its body weight, and sometimes reaches 12.8%.
Construction of the Stone Frog Pond
Wild stone frogs live year-round by shady mountain stream ditches or near stone caves with waterfalls. Their living environment requires sufficient water flow, shade, moisture and fresh water quality, and they like to live in groups in stone caves. Their growth and development, mating and reproduction have long been in a wild state. When stone frogs are domesticated artificially and changed from wild to domestic, tremendous changes have taken place in the living environment and other aspects. For artificial rearing of stone frogs, the frog pond must be reasonably designed so that the frog pond is both similar to the natural environment and convenient for artificial management.
1. Selection of the breeding site: the quality of the environment directly affects the growth, development and reproduction of stone frogs. The frog pond is not limited by location. Generally speaking, the breeding site should be chosen in a place with good water quality, convenient drainage and irrigation, a quiet environment, warm winters and cool summers, neither drought nor waterlogging, convenient management, and prevention of escape and harm. The frog pond can be built indoors or outdoors. Indoors, ventilation, coolness and no direct sunlight are required; outdoors, a shade shed can be set up with the frog pond built below. Building ponds indoors, in courtyards or in the field with makeshift methods are all good living places for stone frogs.
2. Specification requirements for the frog pond: artificial breeding of stone frogs generally adopts intensive culture. When building the pond, attention should be paid to conforming as much as possible to the frog's living habits, providing conditions such as water, land, stone caves and feeding, creating a good living environment, and also making it convenient for rearing and management.
The Breeding Prospects of the Stone Frog
The complete set of techniques for artificial breeding of stone frogs has only matured through research in recent years, and at present the country is still in the initial stage. In addition, due to limitations such as seed sources, technology promotion and breeding conditions, it will be difficult to form a certain production scale in the coming years, and it is even less likely that there will be a rush to jump on the bandwagon and oversupply. As market demand increases and wild resources gradually dry up, the contradiction of demand exceeding supply grows day by day.
For this reason, introducing and mastering mature artificial breeding techniques, forming a breeding scale as soon as possible, and seizing the opportunity to take the first step can obtain relatively good economic benefits.
To breed stone frogs, the first thing is to build a decent stone frog farm. The construction of a stone frog farm requires attention in both site selection and construction. The growth environments and growth conditions required by stone frogs at different stages are all somewhat different.
