Can fish get a concussion?
Yes, fish can get concussions. In fact, they are quite susceptible to them. Fish have a swim bladder that helps them maintain their buoyancy. This swim bladder is filled with gas and is connected to the fish’s intestines. If the fish is hit hard enough, the gas in the swim bladder can escape and cause the fish to lose its buoyancy and sink. This can be fatal for the fish.
So, if you’re planning on hitting a fish with a bat, make sure you do it hard enough to kill it. Otherwise, you’re just giving it a concussion.
