Population Characteristics of Largemouth Bass in Riverine Sections of the Tennessee-Tombigbee Waterway

Population assessments for largemouth bass (Micropterus salmoides) were conducted via electron1 shing during 1987-1988 in tailwaters, bendways, and navigation channels of the Tennessee-Tombigbee Waterway below Aberdeen and Columbus Dams. Growth rates and asymptotic lengths did not differ significantly among locations or between systems. Proportional stock density (PSD), relative stock density (RSD), and catch per unit of effort (CPUE, fish/hour) did not differ significantly between years or systems. Tailwaters generally had the highest CPUE, while navigation channels generally had the lowest CPUE. Development of largemouth bass fisheries in these stream reaches, and especially those associated with tailwaters, could diversify angling opportunities for this species.
