Fish Learns how to use tools
Stumbled upon an awesome read about Atlantic Cod Fish and figured hey, why not share this with you guys? Feel free to comment your thoughts below. So let's get into it. This article was posted on the website called "Animal" by Jason G. Goldman. In short, this article is about a recent study that was done by a group of researchers, lead by Sandie Millot. They had designed a pull string feeding machine for the Atlantic Cod fish to study the behavior of the fish. A number of animals including fish have the capabilities of associative learning, so the researchers we confident that they would be able to operate the pull string feeder. From this research, they found that 86% of the the fish figured out how to operate the feeder by pulling the string with their mouth to get food.
Now here's the interesting part, each of the cod fish were tagged just in front of their dorsal fin with a small tag that had a colored bead on it. The researchers used these tags to identify each individual fish. The behaviors of the fish were video taped, which made it easier for the researchers to analyze.
Three cod fish, out of the 56 cod fish in total, figured out an innovative way to use the pull string feeder. The fish discovered this awesome method by accidentally attaching their identification tag onto the feeder string and swimming with a burst of speed, in an effort to release themselves, and as a result caused the string to be pulled releasing the food. They then fine tuned this method and started to use it constantly instead of using the"mouth method". Imagine That! These amazing fish have discovered using a tool to accomplish a task! Pretty humanistic quality don't you think?
