Many people breed bullfrogs. What are the main points of bullfrog culture technology?

To do a good job in bullfrog breeding, we need to know the dynamics of bullfrog breeding, related biological knowledge, specific management and harvesting, processing technology, economic accounting, production and marketing information, etc. Before the production starts. Only in this way can we ensure the success of aquaculture and obtain ideal economic and social benefits. Humidity also has a great influence on bullfrog, because the epidermis of bullfrog is completely exposed and there is no protective tissue, so the growth environment of bullfrog will be affected if it is too dry, and it can be directly dried for about half an hour. After the breeding scale is determined, plan the bullfrog construction site, and then prepare infrastructure materials, such as red bricks, cement, asbestos tiles, lime powder, sunshade nets, power supply and water diversion, infrastructure builders, excavators, bullfrog ponds, bullfrog canals, and sales of bullfrog seedlings.

The ridge is 40 cm high, the pool slope ratio is 1∶3, the water level is 30 ~ 40 cm, and the water depth is not less than 20 cm. The water inlet and the water outlet are set at the opposite corners of the big pond, and four 80cm× 40cm foam plastic plates are placed in each pond as the rest platform of the bullfrog, and the black sunshade net is used for shading. When building the site, we should consider sewage discharge, bird escape, snake prevention and mouse prevention. To prevent snakes, rats and birds from hurting young frogs and adult frogs from escaping. At the same time, the construction of hydropower pipeline and the setting of sewage pool should be considered. After these preparations are done, you can consider returning seedlings.

Other expenses. Including wages, water and electricity, medicine, transportation, land tax, housing construction, purchase of tools and machinery, depreciation, etc. The above investments should be calculated and raised one by one, and the scale and breeding method of bullfrog should be finally determined.

There should also be sufficient water sources, such as water from rivers and lakes, with the best water quality, high oxygen content and abundant water. It should also be built in a place where it is warm in winter and cool in summer. Not only is the water quality good, but it is also convenient to drain and change water, and there are aquaculture ponds with different uses.
