Are River Fish Safe To Eat?

Many people love to ride a boat and catch fish. People capture themselves with cameras or mobile phones when they caught a giant fish. They brag about the fish they caught, especially if it’s a big one. I also love fishing, but I only did it twice and am looking forward to doing it again. 

Some people like me who love catching a fish in the river usually eat the fish they caught. But is it safe? Yeah, I know most of our rivers are polluted. That is why you have a second thought if you will eat the fish you caught. 

Are river fish safe to eat? Yes and no. River fish can be safe to eat if the river is clean and has no sort of plastics. No, if the river is dirty and polluted. However, fish won’t survive polluted rivers so don’t worry. If you found no fish in the river, it means that the river is polluted or your boat is in the wrong location. 

River fish is a good food especially for people who love to eat fish and on a diet. They have low-calorie, and they are rich in protein. River fish that have been caught in rivers that are polluted may contain chemicals that can be bad for your health. So make sure to check the river before catching a fish. 

How Do Fishes Get In Rivers?

Most fishes can only be found in saltwater ecosystems like the ocean and sea. Also, most of the fishes you found in a river are from the oceans. Now you are wondering, how do fishes get in rivers? 

How do fishes get in rivers? The whole body of water on Earth is connected. Fishes from the ocean drift to the river. After they have drifted, they adapt to their new ecosystem. That is why there are fishes from saltwater that are now living in freshwater, like rivers. That is how fishes get in rivers!

Salmons are fishes that can live in both freshwater and saltwater ecosystems. They go to the freshwater to hatch eggs and to mate, then they go back to saltwater again to survive. Anadromous fish species are the types of fishes that spend their lives living in both freshwater and saltwater. 

Final Words

There are many fishes in the world, and that is why many people, including me, promote to people that we should take care of the body of water on our planet. God gave us the authority and responsibility to take care of our planet, so we should do our best to keep it clean and safe to all living organisms.
