resource competition was intense. Paradoxically, at higher feeding regimes
diet overlap increased although analysis of relative growth suggested
competition occurred at those feeding regimes as well. The insensitivity of
diet overlap at higher feeding regimes may have been due to a lack of
alternative prey, or may suggest that the response variable, relative growth,
integrated effects of two qualitatively different competitive mechanisms
without reflecting a change because intensity of competition remained
relatively constant. These results emphasize the need f`~, more detailed
ecological investigations of interactions between early life stages of
Colorado squawfish and potential non-native competitors. In addition, this
study demonstrated that under experimental conditions, effects of intra- and
interspecific competition can be separated and the outcome of exploitative
resource competition can be determined.
