"Old Man, calm down and let me finish. You are involved in the breeding and deep-sea development of marine products. I'm sure you are also very concerned about many environmental issues. I don't know if you have noticed a detail. There is a type of fish in the Amazon River in South America called the piranha. It has two other names: man-eating pomfret and man-eating fish. It is one of the world's most famous carnivorous fish. The Amazon River is the hometown of the piranha, yet there are very few instances of piranha infestations in the Amazon basin. However, in our country, many fish and shrimp ponds have been infested with piranhas because some so-called kind-hearted people couldn't bear to kill the piranhas they raised and secretly released them into the ponds. As a result, the piranha overpopulated, leaving the ponds devoid of fish and shrimp. Doesn't that seem strange to you?" Liu Shiqing chuckled.
