| | Learning and fish
Steve said this somewhere in his article:
'If you learn to think the way someone else does in a certain area, you’ll tend to behave similarly, and you’ll likely achieve similar results.'
Fish are like this. I watched this science show a few weeks ago. A marine biologist found that fish learn how to avoid predators and find food by swimming with schools of fish. Within that school, there are older, more experienced fish, and the younger fish learn what they need to know from them. However, due to overfishing, the older fish have been fished out. This leaves the school with no trained fish, and they don't survive long in the wild. Many fish face extinction this way. The same thing happens with fish grown in a fish farm; something like 5-10% of the fish released actually survive.
But the biologist found that he could train them, and what they learned, they retained. That particular species of fish he was experimenting with actually retained their knowledge for a year. They live for 2-3 years, so that's pretty long for a fish.
I just thought that was some trivia that made me think, and that I wanted to share it with you on this forum.
