CATDOLL : CATDOLL: What conditions are needed to breed forest frogs?

What conditions are needed to breed forest frogs?

Choose a river basin with lush forests, sufficient water, and an area of ​​more than 100-200 hectares to establish a frog breeding farm. In the breeding farm, build 1 or 2 moon hole ponds for every 10 hectares. There should be drainage outlets and drainage ditches on the surface of the pond. The area of ​​the moon hole pond is 100 square meters and the water depth is 1. It must be more than 5 meters. The water quality is fresh. The hatchery should choose two sides, and the area varies from place to place. It is best to choose a location close to the forest. It is best to let the little frogs go up the mountain in time after metamorphosis. Use plastic film, bricks, galvanized sheets, and asbestos tiles to build frogs to prevent frogs from escaping. Fences are used to breed frogs. When frogs return to the pond for the winter, the water temperature of the pond is kept below 4. Straw, branches and other shelters are placed in the moon hole pond to make the Li Lin frog hibernate. Expansion information: Living habits Frogs have different living habits from other frogs. The annual life cycle can be divided into two stages: water vitality and land vitality.

Frogs stop eating, their activities stop, and their metabolic activity drops to the lowest level. After the underwater life period ends, frogs leave the Moon Cave waters and end their reproductive activities in the swamps. After a short period of reproductive dormancy in the soil around the spawning grounds or under the fallen leaves at high altitudes, they enter the forest and begin their life on land. This is the most active period of the year. Frogs consume a lot of food to meet their growth and development needs. The breeding ground should be as consistent with the living habits of forest frogs as possible. Choose a quiet environment, lush vegetation, and close to water. Frogs cannot be raised in factories, car traffic, environments with frequent human activities, noisy sounds, and places with severe vibrations. If an open space is selected as a breeding ground, the ecological environment must be artificially modified.

Generally, plants can be increased by planting cash crops such as grass or fruit planting. The breeding farm should be a place that is warm in winter and cool in summer. If the ground can be tilted a little to the southeast, the sun exposure area of ​​this terrain is relatively large, and the mild water temperature rises rapidly. In summer, it will be affected by the southeast monsoon. The changing water surface helps to increase the amount of dissolved oxygen in the water, which is beneficial to the reproduction and growth of frogs and water bait. Why is it not profitable to raise Rana? What conditions are required for raising Rana? What procedures need to be handled? The farm must be convenient for water source guarantee and irrigation and drainage. Generally, convenient water sources can effectively control water temperature, dissolved oxygen content in water, and pests and diseases, which is conducive to the growth and wintering of frogs. The breeding farm is conducive to free drainage and the regulation of pond water. There will be no floods in heavy rainy weather, and water can be supplied in time in case of drought.

The water used by a few farms may be related to the water source for farmland irrigation. It should be considered whether there is a contradiction between the two, and proper preparations should be made in the event of drought or drainage to avoid unnecessary losses. Choose a place with abundant bait, which can provide a variety of natural food sources such as plankton, insects, snails, loaches, miscellaneous fish and shrimp, thereby reducing feed costs to a limited extent. Or the area has raw materials and land for producing abundant and cheap feed. For example, there are many livestock and poultry farms, animal manure supplies, food processing stations, and scraps are sold around. There is synthetic bait production for frogs nearby, which is more convenient to use. The wild aquaculture industry should consider facilitating the construction of facilities to prevent escape.

The first point is that the venue must be spacious and bright to achieve the desired effect. The second point is that during the breeding process, you should pay attention to the feeding techniques, which are very important. The third point is that you should master the techniques for feeding according to climate changes.

First, every spring, enough frog eggs should be released or enough frog species should be kept. The density of frog eggs in the hatching pond should not be too high, no more than 2,000 per square meter. During the hatching period, attention should be paid to the freshness of the water, timely water changes, scientific feeding, timely prevention of frog diseases, disinfection of the hatching pond, and timely introduction of fresh loaches into the forest after metamorphosis. Although young frogs do not live in water, they must live on moist land.

Breeding forest frogs requires relatively mature technology. It is necessary to choose a quiet environment, dense plants, and close to water. If there are factories, cars, frequent human activities, noisy and severe vibrations, it is not suitable to breed frogs. Choose open areas as breeding farms, and artificially transform the ecological environment. Generally, convenient water sources can effectively control water temperature, dissolved oxygen content and pests, which is conducive to the growth and wintering of forest frogs. Breeding farms need to be able to drain and irrigate freely, which is conducive to the regulation of pond water. There will be no floods in heavy rain weather, and water can be supplied in time in drought.

This is my first time starting a breeding business. What are the practical techniques for breeding forest frogs?

According to the biological characteristics and living habits of forest frogs, artificially creating conditions for forest frogs to live and reproduce can increase the yield of finished frogs. The main forest frog breeding in the survey area is mainly carried out by professional frog farmers, who use artificial promotion and stocking, that is, in the forest land suitable for the growth and reproduction of forest frogs, egg-laying, hatching and breeding ponds, wintering ponds and nursing houses are built. Every spring, excellent species of frogs or frog eggs are selected for hatching and breeding. After the tadpoles metamorphose, they go up the mountain on their own. In autumn, forest frogs over three years old are caught, commercial frogs are selected for sale, and the rest are returned to the wintering pond for wintering.

The site should be selected in a place with dense forests, low light, high humidity, water sources, and a large number of herbaceous plants. It is best to be on both sides of a mountain stream. The stream should not be too large or too small. You can also choose a ditch pond that will not freeze and dry up in winter. The site size is designed to cover an area of ​​300 square meters for raising 5,000 pairs of frogs. The site needs to build a spawning pool, hatching pool, metamorphosis and feeding pool. The shape of the pool depends on the terrain.

The hatching pool should be built in a flat and open area in the lower part of the ravine. The pool should have a length-width ratio of 5:3 and a depth of 50-80cm. A small ditch should be built beside the pool, and an outlet should be left between each pool and the ditch to facilitate water circulation. The outlet should be sealed with gauze to prevent tadpoles from swimming away.

Hello! This is Qian Ge Chatting About Cars. I am glad to meet you here. After seeing your question: "This is my first time starting a breeding business. What are the practical breeding techniques for forest frogs?", I would like to say that I hope my answer will be helpful to you.

First of all, I want to say that the site for the breeding farm should be selected in a place with dense forests, dark light, high humidity, water source, and a large number of herbaceous plants. It is best to be on both sides of a mountain stream. The stream should not be too large or too small. You can also choose a ditch pond that will not freeze and dry in winter. The size of the site is designed to cover an area of ​​300 square meters for raising 5,000 pairs of frogs. The farm needs to build a spawning pool, a hatching pool, a metamorphosis and a feeding pool. The shape of the pool depends on the terrain.

Secondly, I want to talk about introduction. You can capture or introduce frogs from other farms for breeding and raising seedlings, or you can collect fertilized eggs for hatching and raising seedlings. The time for capturing adult frogs in the wild is early April every year, from 7 pm to 2 am when the forest frogs begin to migrate for reproduction. There are three methods of capture: Light capture method: At night, when adult frogs hide by the embankment, under trees or in the grass, shine a flashlight, and then capture them by hand or with a small gauze net. Blocking the river and dry capture: When the adult frogs are about to end their wintering, block the stream or creek, and then turn over the stones to capture them. Electric capture method: When catching on a large scale, a hand-cranked generator is used to generate electricity, and an electrode is connected. A 230-volt voltage is used to drive the adult frogs in the deep river or in the cracks of tree roots, and then they are captured with a hand net.

Again, in terms of feeding and management. In the hatching period, the focus is to prevent water from drying up and control the water temperature. The water temperature is controlled at 10-15 degrees Celsius, and a plastic insulation shed can be set up on the hatching pool. No water is injected in the early stage of hatching to increase the water temperature; only water is injected in the middle stage without drainage to increase the oxygen content in the water; water is injected and drained in the late stage to keep the water fresh. In the tadpole stage, a certain water level should be maintained to prevent the tadpoles from drying up and dying, and water should be changed frequently to keep the water fresh. The stocking density is preferably 1,000 per square meter. Tadpoles 3-4 days after hatching eat plankton, humus, organic debris, etc., and some cow and horse manure can be added in appropriate amounts. After 12 days, they begin to eat some soft and loose food, and can be fed with cooked cornmeal, bean dregs, bean cake powder, wheat bran, etc., 1-2 times a day. After 20 days, the tadpoles' appetite increases. In addition to increasing the number of feedings, cooked and chopped animal feed can be added. During this period, attention should be paid to preventing harm from wild birds, aquatic organisms, poultry, etc.

Finally, during the froglet period, the density should be properly controlled to ensure food supply. Froglets mainly feed on insects. Three to four days before the froglets come ashore, cow and horse manure or fermented bean dregs can be piled on the bank of the pond to attract insects. Artemisia can also be piled to attract beetles. Lights can also be set up to attract moths. A 25-watt electric lamp should be hung 30 cm above the ground for every 500 square meters. Froglets should be raised in separate ponds from adult frogs to prevent adult frogs from preying on young frogs when feed is insufficient. There is also a wintering period. After September, preparations for wintering should be made. Improve the breeding pond, dig small pits or artificial caves, and retain tree roots, stones and other concealed objects in the field. During the wintering period, the water level should be checked frequently. If freeze-dried pond sections are found, water should be diverted or the frogs should be removed in time.
