Diel Differences in Electrofishing Catch in the Atchafalaya River Basin, Louisiana

SEAFWA Journal Volume 4, March 2017

Published reports indicate night electrofishing may be superior to day sampling to estimate density and diversity of collected shes in some aquatic habitats. However, because shallow, highly turbid waters characteristic of river floodplains present fish detection, navigation, and safety concerns during night electrofishing, many southeastern floodplain sampling programs have focused on day electrofishing. We used paired day and night samples of shes collected by transect (200 m distance for eight minutes) and point electro fishing (1 minute at four points spaced 25 m apart) to assess...
