Can fish get a concussion? It’s a question that has long perplexed scientists and anglers alike. Some say yes, citing studies that show fish can suffer from concussions and other traumatic brain injuries. Others say no, arguing that fish are simply too primitive to experience such complex emotions.
So who’s right? Well, it turns out that both sides have a point. Fish can indeed get concussions, but they probably don’t experience them in the same way that humans do.
Here’s what we know: Fish have a primitive brain structure that is very different from our own. They don’t have a cortex, the outermost layer of the brain that is responsible for higher-order thinking and complex emotions.
That means that, while fish may be able to experience some basic emotions like fear and pain, they are unlikely to experience the more complex emotions that come with a concussion, like confusion, dizziness, and nausea.
So, while fish may be able to get concussions, it’s doubtful that they experience them in the same way that we do. Nevertheless, concussions are serious injuries, and if you suspect that your fish has suffered one, it’s important to seek veterinary care immediately.
