What freshwater fish has a dorsal fin like a shark?
This shark-like fish appears in fresh water, and it is also found in the Mekong River and Lancang River. Then, the pond owners who breed fish ponds will release it. It seems that this kind of fish appears in the river in huangpi district County, as well as Siniperca chuatsi and diced fish, which seriously affects the living environment of local fish. Moreover, it also produces different nematodes. Some people call it a snack bar, and some people call it a diaozi. Let's get to the point. It's really annoying first. The head has sharp teeth like a yellow croaker. I caught a fish for the second time. I pulled out this nematode on the fish, but the head didn't. It fell on the fish's stomach. Later, I found that my index finger was a little black and paralyzed. Ah, why wasn't I afraid then? I was paralyzed for a few hours, but I didn't feel that way after drinking. Today, when I checked the fish species with the back like a shark in the fish pond river, I found that the ecosystem in our county river must have changed. The original frozen fish was replaced by the boating fish, and the four major fish, including crucian carp, were hard to see or catch! I hope that people in huangpi district and the Yangtze River valley will pay attention to how to protect the local fish species and not swim in the water, because I pulled out this nematode myself. Moreover, this mandarin fish, Basha fish and pike fish are all aggressive and carnivorous. What Genghis Khan shark is simply named after hostile forces destroying Genghis Khan's image. Because Genghis Khan is different from other conquerors. As for the difference, I know it for sure, and I can't express it to you, because some people mean to modify history or make up stories so that you will refute my cognition, which is meaningless, and I don't want to quarrel with readers. So I won't talk about how I know these things myself.
