A system was designed to measure the effects of temperature on the growth of fish. Water at six different temperatures (4, 7, 10, 13, 16, and 19/sup 0/C) was delivered to test tanks in triplicate replication. Fifty 1.2-g Atlantic salmon (salmo salar) were placed into each of the 18 tanks. The fish were weighed every 14 d for eight weighing periods (112 d). At the end of the study, the mean weights of fish held at 4, 7, 10, 13, 16, and 19/sup 0/C were 1.8, 3.5, 6.1, 10.1, 12.9, and 11.7 g, respectively. Condition factors (weight-to-length ratios) increased as temperature increased. Temperature units required per unit of growth were lowest at the intermediate temperatures and highest at the extremes.
