The duration of schooling among fish separated and those not separated by barriers. American Museum novitates ; no. 2373
New York, N.Y. : American Museum of Natural History
"Experiments were carried out to determine whether or not the duration of schooling was equivalent among fish separated by barriers and those not separated by barriers. The barriers were either transparent or they partly occluded vision. The results showed that the time pairs of fish spent oriented parallel to one another when separated by barriers was significantly less than the time other pairs of fish spent oriented parallel when they were not separated by barriers"--P. 11-12.
