The New River, Virginia, supports a trotline fishery for catfish (Ictaluridae) that coexists with popular recreational fisheries for smallmouth bass (Micropterus dolomieu), muskellunge (Esox masquinongy), and walleye (Sander vitreus), yet no studies have examined trotline catches or bycatch of these game fish. Trotline effort was estimated by conducting off-site interviews of trotline fishers and field counts of active trotlines. Catch of catfish and bycatch were estimated with experimental trotline sets that used circle or J hooks and two bait types (i.e., live or cut bait). Catch...

Most state wildlife agencies collect harvest data to inform management decisions. However, these data are typically considered across relatively short time periods and are rarely revisited. We present a case study using historical records to investigate potential agents (i.e., harvest, predation, and forest change) influencing the declining white-tailed deer (Odocoileus virginianus) population in the north Georgia mountains. We used long-term black bear (Ursus americanus) and deer harvest data, and indices of forest stand conditions from 1979-2015 on eight Wildlife Management Areas (WMAs)...

Angling participation has stagnated or declined in many regions, threatening the political and financial support for fisheries management. Angler recruitment programs aim to counteract these trends, but most are public programs targeting public water bodies. There are about 4.5 million small ponds and lakes in the United States, most of which are privately owned. These systems may play a major yet hidden role in angler recruitment. Using an online survey of avid pond owners and managers, we explored the ideas that private waters are providing youth angling opportunities, increasing fishing...

Lake Fork Reservoir, in northeast Texas, supports a nationally-recognized trophy largemouth bass (Micropterus salmoides, LMB) fishery which the Texas Parks and Wildlife Department (TPWD) has managed using restrictive harvest regulations since it was opened to public fishing in 1980. De- spite a long history of annual creel and electro fishing surveys conducted by TPWD, data on trophy fish is limited. Fisheries managers' inability to collect trophy-sized LMB using traditional sampling methods is probably the result of a combination of gear biases and low relative abundance of trophy-sized...

White-tailed deer (Odocoileus virginanus) are the most sought after game species in Kentucky. Deer numbers in southeast Kentucky are relatively low compared to other areas of the state, even after a decade of restrictive doe harvest and prior population supplementation. We estimated survival and assessed cause-specific mortality of a representative deer population in this low-density area within or near the Redbird District of the Daniel Boone National Forest in southeastern Kentucky from January 2014-January 2017. Estimated annual survival for does averaged 0.89 and was relatively high...

The shoal bass (Micropterus cataractae) is a sport fish endemic to the Apalachicola-Chattahoochee-Flint Basin of the southeastern United States. Introgression with several non-native congeners poses a pertinent threat to shoal bass conservation, particularly in the altered habitats of the Chattahoochee River. Our primary objective was to characterize hybridization in shoal bass populations near Atlanta, Georgia, including a population inhabiting Big Creek and another in the main stem Chattahoochee River below Morgan Falls Dam (MFD). A secondary objective was to examine the accuracy of...

Blue catfish (Ictalurus furcatus) are native to the Coosa River drainage in northwest Georgia but have been widely introduced outside of this range including Lake Oconee, a 7677-ha impoundment on the Oconee River in central Georgia. Blue catfish abundance and growth rates have increased dramatically since their introduction in Lake Oconee, but their food habits are unknown. Therefore, food habits of blue catfish in this impoundment were determined by examining the stomachs of 808 specimens in the reservoir's upper and lower regions across all seasons from summer 2012 to summer 2013. Diet...

Researchers have used playback as an effective survey tool for ornithological research and monitoring, but amateur use is controversial because of potential negative effects on birds. Despite limited peer-reviewed research on this technique, conservation organizations worldwide have limited or banned the use of playback. Some birders use “pishing” (vocal imitation of avian alarm calls) as an alternative to playback. We investigated the effects of simulated birder playback and pishing on the behavior of wintering birds in northern Louisiana. Four experimental treatments were performed at...

A new tool to provide wetland services is the floating streambed wetland (FSW), an active hydroponic system consisting of a polymer matrix floating substrate in which living plants are established. Water is circulated from beneath the FSW and across a streambed on the upper FSW surface, coming into contact with biofilms attached to the polymer matrix and associated root structures. Research has shown that FSW technology is efficient in removing nutrients and water contaminants, and recent manufacturer reports claim that FSW technology may also increase total fish biomass in small water...

Resource selection by female white-tailed deer (Odocoileus virginianus) and their offspring during the fawning season can influence survival and recruitment. The selection process in females is thought to represent the balancing of often competing demands to minimize predation risk and maximize resource availability to support the energetic demands of lactation. We used a distance-based approach to examine selection of fawn-rearing areas and locations within fawning areas for 20 radio-instrumented female white-tailed deer on Tensas River National Wildlife Refuge, Louisiana. We also...
