Learning at the Fish School

Animal Behavior Students Observe Schooling in Fish

In Mr. Tom Cone’s Animal Behavior classes last week, students participated in an interesting lab about determining the schooling ability of certain fish.

According to Tom Cone, the significance of schooling in fish is that of safety, but also companionship. When fish are good at schooling (gathering in large groups), it helps them look bigger to other fish which is a great anti-predator mechanism. It also helps with procreation, as a fish to mate with is never far away. In addition, studies have shown that schooling fish live longer in groups, which indicates schooling is also a social behavior.

Mr. Cone set up multiple fish tanks with different species of fish inside. Students divided into groups and chose a type of fish to observe. The experiment is set up where one fish is in the large tank and the others are in an adjacent smaller tank. The large tank is separated into four equal quadrants.

Students then began to observe the single fish in the large tank – for 10 minutes they record the location (which quadrant) of the fish. They repeat the recordings with the small tank on the other side of the large tank.

The students then tried to make observations to determine what attracts the one fish to the others (the releaser or stimuli) – is it their color? their size? their markings? They then repeated the entire experiment, but instead of using the small jar of fish, they created their own model of a fish using paper and markers to see if the fish behave the same way.

Students then took the data they gathered and used it to determine if their species of fish is a “schooling” fish. Some students found significant data that their species of fish is great at schooling – their fish stayed mostly in the quadrant adjacent to the other fish. Other students found that their fish may not be great at schooling as they swam all around the tank.
