The fish pond used by Lantian for intensive fish farming is about 200,000 mu, and the aquatic products sold are traded in cash every year, with an amount of up to several hundred million. However, no one knows how many fish are actually in the fish pond. The company’s gross profit is several times higher than that of Dongting, Hunan, which is not far away. Moreover, Lantian has never rationalized this point, but just used “high-tech ecological agriculture, profit is high” as a gimmick. Can't help but be suspicious.
