Which trout has a better memory?

A fish’s personality can tell a lot. From how it learns and responds to threats or predators. There are two kinds of trout that Brown looked at. One was a shy trout and the other was a bold trout. The shy trout are a little more cautious, have a good memory, and can remember a predator’s sense better than the bold trout. The shy trout has a better chance of mating and defending where it lives because it keeps the sense of its predators. So when a predator comes around it knows it and can escape while the bold trout are forgetful and have a lesser chance to mate and survive because it does not remember the predators smell. A trout needs to be able to retain a predators smell wherever it goes because a predator can show up anywhere at any time.

Brown and his team set up a tank with removable Plexiglas and tested which fish would escape the test tank faster. He found that the bold trout would move quickly and use risky behavior. While the shy fish was more cautious and took its time to avoid being risky. Brown and his team also had the trout remember the smell of pumpkin seed. They tested to see which trout would remember the smell after 24 hours and after eight days. By the end of their research they found that the personality of the trout helped them remember the smell. Both the bold and shy trout remembered the smell after 24 hours, but when it came to the eight days the shy trout came out on top.  

            I feel that personalities can tell a lot especially about trout. Some animals are smart while some are not. This test of the two trout shows that even though they are the same fish they do not retain information the same. This test was a good way to determine which trout would remember and which one would not, but I feel as though they should have done more than just this test to test their memory. I chose this article because I love animals, and I have been trout fishing a few times. It was interesting to learn about one of the animals I hunt and see how their minds work. The article is relevant to society because some people, especially animal science people are interested in animals and fish, and some people, like me, like to learn about animals they hunt. This article also helps show society that not all trout have bad memories like the bold trout.
