Thanks to Jeff E.!
Ed note: Not sure if this is fake or real, but here’s one explanation I found. “In humans, our lungs work to exchange oxygen from the air to replenish our blood cells and exhale waste gasses. In fish, gills work similarly. When oxygenated water is passed over specialized tissues, oxygen from the water is exchanged into the fish’s bloodstream.
When there isn’t enough oxygen in the water fish can indeed suffocate, which is actually a big problem in the ecology of our modern oceans where shifting currents have created pockets of low-oxygen water. Diluting the oxygen concentration in water by adding carbon dioxide from soda makes extracting oxygen much more difficult, which can cause a fish to panic and try to escape.
As a science lesson, this video offers several insights into animal – and human – behavior. However, as a fishing tactic, this method probably isn’t likely to net you a whopping catfish.
Still, we can always count on the depths of the internet to inspire the human imagination.”
Cheez! Fake or real – the idea of suffocation and panic is cruel. From your comments, this is too close of a parallel to the effects of COVID-19. Not needed today.
