calculated = 4.32). At the 95% confidence interval, the difference in mean weight = 2.25 +/- 1.02. These results indicate that there is a difference between the two groups of fish with respect to growth (TL and weight). The fish from pond #2 had better growth than the fish from tanks #1 and #2. However, the fish from tanks #1 and #2 were able to survive better than the fish from pond #2. The statistics mentioned above should be double checked prior to publication. After weighing and measuring the fish were held in tanks #2, #3, and #4 until 16-18 May 1988. During this period tank #2 water temperatures varied from 11-12.50C, and dissolved oxygen levels ranged between 4-7.4 ppm. The fish were fed a total of 3,284 grams of commercial trout diet and seven mortalities were recorded. The water temperature in tank #3 was 11.00C and dissolved oxygen levels varied between 3.2-7.5 ppm (Appendix D). The fish in tank #3 were fed a total of 4,223 grams of commercial trout diet, and no mortalities were recorded. The water temperature in tank #4 was also 11.00C and dissolved oxygen levels varied between 3.3-6.8 ppm (Appendix Q. The fish in tank #4 were fed a total of 2,572 grams of commercial trout diet, and 107 mortalities were recorded. Most of these mortalities appear to have been caused by various bacteria and parasites. Evidently, fish were again sent to Federal Disease Control Center at Fort Morgan, Colorado for analysis. These fish were found to have been infested by Ichthvobodo (Costia), Pseudomonas putrifaciens, Pseudomonas aeruginosa, Aeromonas hydrophila, Aeromonas sobria, and Klebsiella oxytocoa. Also, some of the fish had gas bubble accumulations behind the eyes (Letter 2). Thus, a total of 114 mortalities were recorded during this time period. It is interesting to note that only 7 of the mortalities were from fish that had overwintered in pond #2. The remaining 107 mortalities were from fish that had overwintered in the tank #2.
