Relationships between Hydrology and Largemouth Bass Growth in the Ouachita River, Arkansas

SEAFWA Journal Volume 3, March 2016

We explored whether increased river flows negatively affected growth of largemouth bass (Micropterus salmoides) in the lower Ouachita River, Arkansas. To test this hypothesis, largemouth bass (n = 460) were collected during 2008-2010 from the Felsenthal Reservoir region of the river. Largemouth bass were aged and annual growth increments were calculated using standard back-calculation techniques. Growth of largemouth bass was relatively rapid in the Ouachita River, with von Bertalanffy growth model parameters determined as L = 513 mm, K = 0.324, and tο = -0.314;...
