Bullfrog is a highly valuable amphibian. How to build a bullfrog breeding site?

Bullfrogs are classified as an animal in the genus Ranidae, Chordata, Amphibia, Anura, Ranidae, and Rana. Frogs are tender, nutritious, and delicious, and are a favorite delicacy of the Chinese people and a precious food at state banquets. In terms of medicinal use, a water depth of 15 to 40 cm is more suitable. The land accounts for about 1/3 of the total pond area. It is best to have 2 to 3 spawning ponds for the parent frogs in different spawning periods to lay eggs and ejaculate. The ecological environment of the spawning pond should be similar to natural conditions to facilitate reproduction.

Bullfrogs are extremely sensitive to temperature. If the temperature drops to ten degrees, they will automatically enter hibernation. If the temperature drops below zero, bullfrogs will be directly frozen to death. In addition, if the temperature is too high, it may also cause heat death. The best growth and development temperature for bullfrogs is 25-30 degrees. After determining the breeding scale, plan the bullfrog construction site, and then start preparing infrastructure materials, red bricks, cement, stone tiles, lime powder, shade nets, electricity, water diversion, infrastructure construction personnel, excavators, bullfrog ponds, bullfrog channels, sell bullfrog seedlings, etc.

Some other large frogs are also called bullfrogs, such as the African box frog, the Indian tiger frog, and the South American slender-toed frog. They have the advantages of fast growth, delicious taste, rich nutrition, and high protein content. Let's take a look at what conditions are needed for bullfrog breeding! In addition, a large amount of water needs to be changed during bullfrog breeding. Therefore, when choosing a site, it is best to choose a site close to a water source or a site that can guarantee a water supply. When building the site, it is necessary to consider sewage discharge and escape prevention, bird prevention, snake prevention, and rat prevention, etc., to prevent snakes, rats, and birds from invading young frogs and adult frogs from escaping. The first preparation is to cultivate talents first and arm your mind with scientific knowledge. Only then can other problems be solved, and only then can you spend less money, do more things, and do good things to ensure the success of bullfrog breeding.

Generally, there are several or dozens of bullfrogs together. Therefore, when breeding bullfrogs artificially, try to choose a place with sufficient water, humidity, warmth, weeds, and shade to build a bullfrog pond in a place that meets the growth needs of bullfrogs. The frog pond should be surrounded by brick walls to prevent bullfrogs from escaping.

There are two types of ponds: cement ponds and earth ponds. The area of ​​a cement pond is 30-50 square meters, and the depth of the pond is 1 meter. There should be a platform of 1/4 area in the pond, which should be paved with bricks, cement, etc. to prevent young frogs from swallowing mud and bait together, causing indigestion. The water level should be kept close to the platform to facilitate young frogs to go ashore to rest and forage. The area of ​​an earth pond is generally 100 square meters, the ratio of water to land area is 1:1, the slope of the pond bank is 1:2.5, the water depth is 40-100 centimeters, and barriers are set up around the earth pond, 150 centimeters high and buried 30 centimeters underground. Frogs are prone to death when exposed to the sun, so a pergola should be set up

The bullfrog breeding site should be built in an environment suitable for the growth of bullfrogs. Because the environment in which bullfrogs grow is very humid, so the site must be well built.

1. In mountainous areas, in a small basin surrounded by mountains on all sides, or in a place surrounded by mountains on three sides and with a pan in the middle of two mountains, the mountains can be used as a natural barrier for bullfrogs to escape. A 1.5-meter-high wall can be built in the gap of the mountain, and a certain number of breeding frogs can be released in waters suitable for bullfrog breeding.

2. To increase aquaculture in reservoir areas, suitable bays should be selected for damming and construction to create a frog-raising environment with a small outlet, a wide belly, a flat bottom, facing south with back to the mountain, sufficient sunlight, and a wide water surface.

3. When raising frogs in lakes, choose a lake branch with a water depth of 1-2 meters. Use bamboo stakes or reinforced concrete columns to pile in a straight row at the narrowest point and build a frog fence without a foil door to separate the lake branch from the lake.

4. To raise frogs in ditches, choose a river channel with good conditions. In a section with a wide water surface and a slow-flowing area, build two foils in the shallow water areas at both ends and build escape-proof walls on both sides of the coast.

5. When raising bullfrogs in rice fields, choose fields with sufficient water sources, convenient irrigation and drainage, and strong water and fertilizer retention capabilities. It is best to enclose them together with nearby lotus root fields, ponds, etc. to form a more ideal bullfrog breeding farm.

Bullfrog is an economic aquaculture industry. What are the requirements for bullfrog farming?

Amphibious:

Bullfrogs are amphibious and live in rivers, ponds, swamps and shore grass. During the day, they often float on the water or hide in the water.

They live in wet and cool waterside grasses and caves, and dive into the water when disturbed. They move around at night in search of food.

In the hot summer, they often live in cool caves, dense grass, and crop fields; in the severe winter, they burrow into the ground 10-40cm deep.

They live in unfrozen soil layers, caves about 1m deep, or mud about 6ocm deep, waiting to break out in the spring of the following year.

Bullfrogs like to live in groups, often with a few or thousands of them living in the same place.

When the habitat deteriorates, such as water drying up, food shortage, or unbearable heat, they can no longer move.

To survive, bullfrogs will migrate to other suitable environments.

They move to places with good environments such as ponds, ditches, and swamps, where they play with each other, cling to each other and reproduce.

.

Extensive breeding in the wild. It can be divided into two categories: full natural breeding and semi-extensive breeding. Common breeding methods include reservoir breeding, swamp breeding, lake breeding, river breeding, and rice field breeding. Make full use of natural bait and other natural conditions, define the breeding range, release bullfrog seedlings, appropriately increase the feed, and harvest and capture regularly. Its characteristics are large breeding grounds, small investment, high returns, less human intervention, but low yield per unit area.

Intensive breeding. It is a breeding method that uses artificial feed and non-agricultural land to build ponds and conduct intensive and fine management. According to the difference in breeding sites, it can be divided into pond breeding, field breeding, courtyard breeding, indoor breeding, constant temperature breeding and other methods. Its characteristics are high breeding density, high yield per unit area, high input and high output, and significant economic benefits.

Building a Frog Pond

The farm should be warm in winter and cool in summer, away from noise, with convenient transportation and sufficient power supply to facilitate breeding production. The quality of water source conditions is the key to the success or failure of frog breeding. Generally, it is required that the water source is sufficient, the drainage and irrigation are convenient, the water quality is pollution-free, and it meets the fishery water quality standards. Every 100 square meters can be a large pool, and each large pool can be divided into 4 small pools. The pool is surrounded by a 40-mesh screen. The screen should be 1 meter higher than the bottom of the pool, and the bottom of the screen should be buried 20 to 30 centimeters in the soil; the pool ridge is 40 cm high, the slope is 1:3, the water level is maintained at 30 to 40 cm, and the water layer depth cannot be less than 20 cm, otherwise the water storage is too small, the water is easy to be turbid, and bullfrogs are easy to get sick. It is advisable to use a rectangular pool for easy operation. Plastic pipes with a diameter of 10 to 12 cm can be used as water supply and drainage pipes, and the location of the inlet and overflow holes should be at the diagonal of each large pool. In each small pond, four 80×40 cm white foam plastic boards with buoyancy are placed as resting platforms for bullfrogs. A black sun net is used above the pond to provide shade to prevent exposure to the sun in summer.

Before stocking, use 50-75 kg of quicklime or 10-15 kg of bleaching powder (effective chlorine content is about 30%) per mu of dry pond for disinfection. Generally, stocking can be done after 10 days of clearing and disinfection. Before stocking, young frogs can be soaked in 20ppm (gas or solution concentration unit, indicating parts per million) potassium permanganate solution for 10-20 minutes. During the soaking, there should be personnel on site to observe, and immediately remove the froglets if any abnormality is found. The stocking density of young frogs is 60-80 per square meter. As individual differences change, stocking is carried out in different levels and ponds. The stocking density of adult frogs is 30-40 per square meter.

Bullfrogs are amphibious animals. The environment for raising bullfrogs needs to be in rivers, ponds, swamps and shore grass, which is conducive to their survival. The food composition of bullfrogs is mainly animal feed. When they are still tadpoles, they can be fed with egg yolk, blood meal, horn powder, etc., or soy milk, bran, flour, etc. The food range of young frogs and adult frogs includes: annelids, such as earthworms; arthropods, such as crustaceans and shrimps; mollusks, such as snails and clams; fish, amphibians, reptiles, juveniles and mammals. Bullfrogs are ferocious by nature, and it is common for big frogs to eat small frogs. Artificially bred bullfrogs should be raised separately according to size to avoid cannibalism.

The bullfrog pond production area requires sufficient water source, convenient drainage and irrigation, quiet environment, pollution-free water quality, convenient transportation, etc. Bullfrogs are thermophilic animals, with the optimum temperature for growth at 25-32℃ and the optimum temperature for reproduction at 20-30℃. They generally do not lay eggs below 20℃ or above 30℃.

1. Pond selection: sufficient water source, convenient irrigation and drainage, pollution-free water quality, quiet environment, convenient transportation, and sufficient power supply are required.

2. Frog pond construction: Every 100 square meters is a large pond, and each large pond is evenly divided into four small ponds. Each pond is equipped with a foam plastic board as a resting platform for bullfrogs, and is shaded with a black sunshade net.

It requires a cool and humid place. When breeding, you must pay attention to breeding it in some grass in a pond or swamp. It has very high requirements for these environments and likes cool and humid places. These conditions must be met to breed it.
