Good reasons to stay in schools… - why fish form schools - includes related information Ranger Rick - Find Articles
You've probably heard this joke: 'Why are some fish smarter than others?' The answer is, 'Because they hang out in schools.'.
But schooling is no joke - for some fish, it really is the smart way to survive..
A school of fish can have just a small number of members - or it can have more than a million! The fish in a school are usually the same species (kind).
Some species of fish live in a school almost all their lives.
Others form schools only at certain times, like right after they've hatched..
A school can be made up of fish that just hang around together.
But many schools are very organized, like this school of French grunts (see photo at left).
The fish swim barely a fin's length away from each other.
And each fish in the group moves at the same speed and in the same direction as the others.
In the blink of an eye, a whole school will swim right, left, up, down, or even make a U-turn - all at the same time.
How do the fish move like that without swimming right smack into each other? One way they do it is by being copycats.
Each fish watches its neighbors and copies every move they make - quickly! Meanwhile, the neighbors are copying their neighbors, and so on.

Education In the past, 4th grade students from Lake Quinault School reared coho salmon in the classroom.
At the fry stage the students return to the hatchery to release the fry into Cook Creek so the tiny fish can over-winter and begin their migration to the ocean in subsequent years.
A student from Lake Quinault School is s selected who is interested in pursuing an education in fisheries or environmental studies.
The first student to participate was Matt Harris who represented Lake Quinault School from Amanda Park, Washington.
This program allows for a local high school student to gain hands on experience with fish culture and become familiar with the daily operations of a fish production facility.
As part of this program Matt was required to conduct special studies pertaining to stream ecology and fish condition factor analysis.
