V1 l <br />and two different rations (satiation and 50% satiation). The- effect <br />of ration on growth rate was significant; but both rations appeared to <br />be in excess, and growth was, actually better a~ the 50% satiation <br />feeding level for fish held at 15, 20, and 25 C. The effect of tem- <br />perature on growth rate was highly significant, with maximal growth <br />occuring at 25 C. Fish gained approximately 0.3 grams at 15 C, 0.9 <br />grams at 20 and 30 C, and 1.7 grams at 25 C over the 12-week period. <br />The combined results suggest that 25 C is the final thermal pre- <br />ferendum and the temperature for maximal growth rate of Colorado <br />squawfish under optimal conditions, though Colorado squawfish should <br />function well within a temperature range of 20 to 30 C. <br />(47 .pages) <br />
