    Catch and release is stupid. Do not traumatize fish needlessly. You could have just not went fishing.

      You also release fish that are too small to have mated yet ( at least you do in Germany). Maybe this is the case here.

        Trauma is a general term for injury. This is why a psychological trauma is called that. It’s as nonspecific as it gets.

          It also means the mental distress from an injury, which is the psychological sense. So while they’ll get physical trauma (probably minor for most catch and release), it’s debatable how much fish can feel psychological trauma.

          The post I responded to seemed to be talking about psychological trauma, hence my comment.

        Ehhhh, that would only be true if you finagle trauma into a very limited set of behaviors post trauma.

        Fish do have an avoidance mechanism where they won’t revisit places that they’ve been startled or injured in

        But they also lose that behavior over time as long as the events are reproduced. Which happens in mammals, including humans, too; just not as fast or as easy.

        You gotta understand that most fresh water fish operate in smaller ranges, so if they held onto the trauma response too long, then their entire territory becomes locked off. So their brains run a more limited avoidance pattern than what we do. But they do have them

        While it would b e possible to dick around with the semantics around what is and isn’t “trauma”, fish absolutely have fear responses and avoidance of locations after injury or stress. If you don’t want to call that trauma, fine, whatever. But it is a mechanism very similar to what mammals, birds, and even reptiles have.

        It isn’t about intelligence at all. It’s about memory and risk aversion.
