Abstract
Abstract A comparison of the sampling effectiveness of a backpack electroshocker and small-mesh seine was conducted on the upper Cahaba River in the Valley and Ridge physiographic province of north-central Alabama. Each of 15 sites was sampled once during fall 1995 (20 September–23 October), spring 1996 (2 May–20 June), and fall 1996 (20 September–16 October). Sampling was conducted with both gears on the same day, and the same amount of sampling time was allocated to each gear. Samples were segregated into seven groups (Cyprinidae, Catostomidae, Percidae, Centrarchidae [further subdivided into sunfish-crappie and bass categories], and other families as a group), and comparisons of the percent relative abundance (PRA) of groups were made between gears at each sampling station. The PRAs of the groups differed significantly between gears at all 15 stations. Cyprinid PRAs were consistently higher in seine collections, whereas percids, sunfish-crappie, and bass PRAs were higher in electroshocker collections. ...
