Underyearling chum fry were held in fresh water and salt water at two different temperatures and under two different photoperiods. The first tests were made after forty days acclimation. Aggregations were greater in salt- than in freshwater (p < 0.01). At the lower temperature the fish were more aggregated than they were at the higher temperature (p < 0.05). Photoperiod effects were not significantly different. The biological meaning of these results is discussed. It is concluded that, under the conditions of this experiment, chum salmon fry show true schooling (as defined by Keenleyside, 1955) only in salt water. / Science, Faculty of / Zoology, Department of / Graduate
