摘要

Size-specific growth of bluegill, black crappie, and freshwater drum wassignificantly different over four years in Navigation Pool 8 of the upper Mississippi River. The results are consistent with predictions of the Flood Pulse Concept. Extensions of analysis of covariance (ANCOVA) models were used to account for differences in growth due to the size of fish and tested for annual differences in growth rates. Planned comparisons examined differences in growth among years with a large flood event, two years of normal hydrology, and a drought. The data suggest that (1) patterns in growth for some riverine fishes are consistent with the Flood Pulse Concept, (2) droughts may be of greater consequence than floods to riverine communities, and (3) growth responses related
