Florida freshwater habitats provide many essential functions including flood control and nutrient sequestration. While serving as habitat for many fish and wildlife species, wetlands also contribute significantly to the outdoor recreation industry. Despite these services, aquatic habitats contin- ue to face threats, such as urban encroachment, water withdrawals, water-level stabilization, sedimentation, non-native species introduction, cultural eutrophication, and climate change. With Florida’s increasing human population, encroachment and development continues into natural areas, stress-...

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...

Spotted bass (Micropterus punctulatus) provide popular recreational fisheries in southeastern U.S. streams. We studied spotted bass population structure and diet from wadeable (< 1 m deep on average, n = 174, 21 sites) and non-wadeable (n = 498, 32 sites) reaches of the Lake Pontchartrain Basin in Mississippi and Louisiana to determine if populations should be managed separately by stream size. Sampling occurred April-November 2009-2012 by hook-and-line angling, boat-mounted electrofishing, and seines. Size structure was similar between stream type and with few quality-sized fish (PSD...
