Abstract:

The distribution patterns and food habits of young-of-the-year (YOY) fishes in a
lentic area adjacent to the  main channel of Pool 7 of the upper Mississippi River
were studied. Habitats sampled grouped distinctly based  on percent composition
and abundance of YOY fishes with those having submergent vegetation
dominated by a  number of important sport species. In late spring, the grouping of
stations depended on the presence or absence  of newly transformed northern pike
(Esox lucius). In early summer, stations did not differ as distinctly in 
composition, but in total abundance of young. Those stations with submergent
vegetation had total catches  which were more than double those elsewhere. By
late summer, submergent and mixed vegetation stations  formed a distinct
assemblage influenced by the preponderance of three species of sunfishes. (DBO).
