Study of Fish in the Main Channel of the Mississippi River Between River Miles 500 and 513.5.

Abstract

The main channel habitat in Pool 14 (river miles 500 to 513.5) of the upper Mississippi River was sampled to determine the occurrence, distribution and relative abundance of fishes. Gear types used were gill net, trammel net, hoop net, bottom trawl, midwater trawl, seine and electrofisher. Thirty-nine species of fish were caught from May 1979 to April 1980. The most abundant species of 2692 total fish were channel catfish (59.0%, which wre mostly YOY), silver chub (12.0%), mooneye (10.3%), shovelnose sturgeon (9.4%), freshwater drum (2.5%), flathead catfish (1.7%), and river darter (1.7%). Catch rates and species compositions varied seasonally; the most fish caught in July (1027) while the fewest were caught in February (4).
