Hello, I'm from Henan, too, but I'm not very clear about the industry of breeding bullfrogs in Henan. I just know something about the market of bullfrogs in Henan. Let me tell you briefly.
At present, there is still a great demand for bullfrogs in Henan. Basically, bullfrogs are used in restaurants in large shopping malls or in hotels and restaurants outside. In particular, bullfrog pot is very popular in Henan, because the meat of bullfrogs is delicious, chewy and not greasy to eat, and it is even better to eat with rice. Under such a large market demand, I think there are still many bullfrogs in Henan, but this is only a personal guess, but in other words. I am experienced, so it is good to come to Henan for development. No matter whether others are breeding or not, the market demand is here, so there is still a lot of room for development. Besides, there is no need to worry about the sales of bullfrogs. You can sign a long-term supply and demand contract with restaurants or hotels and restaurants in large shopping malls.
If you are worried that the quantity of breeding will be in short supply, you can also use Yubao, an em bacteria in aquaculture. Now many aquaculture farmers are using Yubao, which belongs to microbial probiotics. Its biggest advantage is to enhance the immunity of bullfrog, prevent diseases in bullfrog breeding, reduce mortality and morbidity, and you don't need to buy veterinary drugs. Moreover, it can promote the growth of bullfrog, make it eat more, and shorten the breeding time. However, Yubao itself is nontoxic. Therefore, farmed bullfrogs don't have to worry about the toxicity in their bodies, and there will be no problem in quality inspection at that time, and the fish treasure itself is also very cheap. A bottle of diluted water can be fed to bullfrogs many times. I hope my answer will help you.
