Economic Impacts of Onshore Fishing Sites and Fishing Tournaments on the Mississippi Gulf Coast

Our study attached a monetary value to marine resources associated with fishing on the Mississippi Gulf Coast. In 2001, we conducted on-site surveys (N = 475) to collect expenditures of marine onshore anglers and marine fishing tournament participants in the Mississippi Gulf Coast three-county region. We then determined the extent and economic impacts of these activities and integrated marine onshore angler economic impacts and attendances into a Geographic Information System (GIS) for the Mississippi Gulf Coast. Our survey response rate was 86%.

Human Dimensions Research and Programmatic Planning for the South Carolina Department of Natural Resources Freshwater Fisheries Section: A Case History

This paper demonstrates the applicability of human dimensions research to the development of programmatic priorities and strategies for the South Carolina Department of Natural Resources (SCDNR), Freshwater Fisheries (FWF) Section. Responsive Management (RM), a Virginia-based research firm specializing in public attitudes toward natural resources, conducted telephone surveys in 1998, 2002, and 2004 of South Carolina residents and licensed anglers to examine their attitudes and opinions toward fishing, fisheries management, aquatic resources, and various programs of the SCDNR.

Evaluation of Catch Card Reporting at Mississippi State Lakes

We evaluated voluntarily completed catch cards as an alternative to access point surveys at intensively managed state-owned fishing lakes in Mississippi. Catch cards, with signs encouraging participation and completion, were conspicuously available to anglers. Five percent of anglers voluntarily completed catch cards; response rate increased to 13% when agency personnel verbally requested participation in the catch card program from those anglers they encountered on-site.

Hybrid Striped Bass in Urban Ponds: A Pilot Study on Angler Demographics, Attitudes, and Fishing Success

Urban fishing programs in Arkansas rely primarily on put-take stockings of channel catfish and rainbow trout. We evaluated hybrid striped bass as a potential addition to urban fisheries by stocking this fish at densities of 95 and 96 fish/ha in two urban fishing ponds. Angler surveys were conducted three times daily for five weeks following stocking to determine angler demographics, fishing success, and attitudes/preferences. We surveyed 320 anglers comprised primarily of local urban residents.

Distribution of Freshwater Bivalves in the Canoochee River Drainage, Georgia

The Canoochee River originates in the Southern Coastal Plain of Georgia and flows through the Coastal Flatwoods to terminate at the Ogeechee River. The Canoochee Drainage is the largest tributary of the Ogeechee River and is a fifth-order woodland stream. Investigators surveyed 83 sites for freshwater bivalve presence, noting species and counting individuals. We analyzed water chemistry parameters including nitrate nitrogen, total inorganic nitrogen, total dissolved phosphate, and total dissolved copper.

Ten-year Assessment of the Unique Fishery of the Okefenokee Swamp

The Okefenokee Swamp is the largest freshwater wetland in the United States; however, population dynamics of the fish assemblage within the swamp are poorly understood. Fish surveys from 1992-2001 indicate that two species, bowfin (Amia calva) and flier (Centrarchus macropterus), are the numerically dominant taxa of the eastern portion of the swamp, representing over 88% of all fishes collected. Results indicated that the fish assemblage was persistent and stable in terms of constancy of dominant species presence and their abundances.

Temporal and Spatial Trends in Fish Communities Inhabiting Two Freshwater Tidal Wetlands of the Cooper River, South Carolina

From April 1999 through February 2000, we electrofished fixed transects in two freshwater tidal wetlands of the Cooper River, South Carolina, to examine how spatial and temporal variation in these habitats influenced fish community composition. The Dean Hall site consisted of a collection of tidal creeks with intertidal, emergent vegetation and large fluctuations in submersed habitat due to tide. The Bonneau Ferry site was lacustrine, dominated by submergent vegetation, and fluctuated very little with the tide. We found 34 total species.

Persistent and Emerging Diseases of Freshwater and Marine Fishes in the Southeast: Implications for Fishery Management

Several diseases of fish present challenges to both fishery managers and aquaculturists in the Southeast. Emerging diseases along with a suite of known and persistent diseases can present management challenges for native species and biodiversity, can cause loss of recreational fishing opportunities, and can affect local economies or reduce profitability in commercial aquaculture. Emerging diseases such as mycobacteriosis in striped bass, epizootic ulcerative syndrome in menhaden, and spring viremia of carp present some new challenges to fishery managers.

Caging Atlantic Menhaden: Collection, Husbandry, and in situ Bioassays with a Sensitive Estuarine Species

Cages as tools for in situ bioassays have a proven track record in monitoring the effects of effluent and sediment toxicity. Application to biomonitoring, however, has received comparably little attention. With the increasing threat of harmful algal blooms to both humans and aquatic organisms, their use as sentinels for early warning and for the examination of organism response in situ is evident.

Relationships Between Landscape Characteristics and Space Use of Raccoons in Two Managed Pine Forests

Raccoons (Procyon lotor) are ecological generalists that use a variety of landscape and habitat types. Although space and habitat use are well understood for raccoons throughout the southeastern United States, relationships between space use and landscape characteristics are not. We examined relationships between space use and landscape characteristics for 95 radio-marked raccoons monitored during 1996-1997 on two adjacent forested landscapes that differed in forest management strategies.

Raccoon Abundance and Rio Grande Wild Turkey Production in Central Texas

An understanding of spatial and temporal dynamics of wild turkey (Meleagris gallopavo) populations is essential in setting management goals. In central Texas, raccoon (Procyon lotor) populations have increased in recent years, causing concern that they may be limiting Rio Grande wild turkey (M. g. intermedia) production. We used two long-term data sets in central Texas to explore the relationship between raccoon abundance and Rio Grande wild turkey production at the regional, county, and local scale.

Factors Affecting Wild Turkey Recruitment in Western Virginia

Annual recruitment of eastern wild turkeys (Meleagris gallopavo silvestris) should be closely monitored to regulate fall turkey seasons and reduce risk of over-harvest. However, previous studies have not encompassed the spatial or temporal scales needed to produce models that can consistently predict recruitment over a large region. Our objective was to assess the ability of using long-term data sets of sex-age ratios, oak (Quercus spp.) mast, and weather variables to forecast annual wild turkey recruitment in western Virginia.

Seed Production and Cost of Mourning Dove Field Plantings in Alabama

Cost-effectiveness of various planting options is an important consideration in selecting planting strategies for mourning dove (Zenaida macroura, hereafter ‘dove') fields. We documented costs and seed yields of three cultivated and three wild dove foods, and tested effects of fertilization rate, row-spacing, and seeding rate on seed yield of highly-preferred dove foods. Browntop millet generally had the greatest seed yield and lowest cost/kg of seed produced.

An Evaluation of Sampling Methods for White-winged Dove Surveys in Urban Areas

Texas Parks and Wildlife Department (TPWD) has used auditory call counts annually since 1949 to monitor white-winged dove (Zenaida asiatica) populations in the Lower Rio Grande Valley of Texas. Recently, white-winged doves have been expanding their distribution, and now the largest populations occur in urban areas north of their historic south Texas range. It has become necessary to develop an urban survey method to better monitor these populations. We compared two call count sampling methods for surveying white-winged doves in urban environments (i.e., transects vs.

Microhabitat Characteristics of Nocturnal Roost Sites of American Woodcock in East Texas

Long-term declines in American woodcock (Scolopax minor) populations may be partially the result of low survival rates on wintering grounds especially in nocturnal habitats. We compared microhabitat characteristics of woodcock nocturnal roost sites to random sites in eastern Texas. We located woodcock roost points by nightlighting in winters of 2000-01 (45 points) and 2001-02 (74 points). Percentage bare soil, sapling-size tree canopy cover above 0.5 m, and sapling density were greater at roost than random sites.

Effect of Prescribed Burning of Clearcuts on Ruffed Grouse Brood Habitat

We evaluated short-term effects of prescribed burning of clearcuts on potential ruffed grouse (Bonasa umbellus) brood habitat in oak-hickory forests in western Virginia. We divided six <1-year-old clearcuts into two portions and designated one portion for prescribed burning during late fall or winter. Because of dry conditions, only four treatment areas were burned. We monitored habitat conditions on burned and unburned portions of clearcuts during the growing season preceding treatment and during the two subsequent growing seasons.

Evaluation of a 254-mm Minimum Length Limit, 25-fish Daily Bag Limit on Crappies at Sam Rayburn Reservoir, Texas

As part of a statewide regulation change in 1990, Texas Parks and Wildlife Department adopted 254-mm minimum length and 25-fish daily bag limits on crappies (Pomoxis spp.) at Sam Rayburn Reservoir. The objective of the regulation was to increase the size of harvested crappies while maintaining pre-regulation catch rates, harvest rates, and yield. Population and fishery parameters during 3-year unregulated and 8-year regulated periods were compared.

Exploitation of Largemouth Bass in Wheeler Reservoir, Alabama and Simulated Effects of Minimum Length Limit Regulations

Between the early and late 1990s, a nearly 10-fold decline in angler catch rates of large (?2.27 kg) largemouth bass (Micropterus salmoides) was observed in Wheeler Reservoir, Alabama. The objective of our study was to estimate the exploitation rate of largemouth bass and compare predicted population responses from simulated minimum length limit (MLL) regulations in an attempt to explain this reduction. Exploitation was seasonal, with most of the harvest occurring during spring.

20 Years Later—A Comparison of Recreational Fishing Pressure and Catch Statistics at Cat Island, Mississippi

Roving-clerk creel surveys were conducted at Cat Island, Mississippi, during two three-year periods: 1977-1979 and 1997-1999. Angler interviews provided data of species caught with estimated weight and number, as well as duration of fishing activity. Periodic aerial counts of fishermen provided further estimates of total fishing activity. Fishing pressure increased significantly (P ? 0.05) during the 20-year study interval in numbers of fishermen and total hours fished.

Ecological Changes Following an Alewife Introduction in an Oligotrophic Reservoir: A Case History

Alewife (Alosa pseudoharengus) was introduced into oligotrophic Mayo Reservoir, North Carolina, during 1992 or 1993. The species established a self-sustaining population and increased from <1% of total fish biomass in 1993 to 31% in 2000. Size-selective planktivory by the species, a well-documented phenomenon in other alewife introductions, was implicated in observed changes in the reservoir zooplankton community.

Response of Plant and Invertebrate Communities to Pothole Blasting in a Giant Cutgrass Marsh

Thousands of hectares of tidally-influenced, forested wetlands were cleared in the South Atlantic Coastal Zone and put into rice production during the eighteenth and nineteenth centuries. Many of these ricefields were abandoned in the late 1800s and were not maintained thereafter; hence, they no longer have functional dikes and provide poor habitat for waterfowl and wading birds due to colonization by dense stands of giant cutgrass (Zizaniopsis miliacea).

Animal Welfare-based Modification of the Rio Grande Wild Turkey Funnel Trap

The funnel trap has proven a safe (for handlers), efficient, low-manpower method of capturing Rio Grande turkeys (Meleagris gallopavo intermedia). Field biologists in Texas maintain that private ranchers accept this technique more readily than alternatives because it is passive and only requires one person. The impact of the technique on animal welfare, however, has not been addressed. In 2002, in the first year of an ongoing population ecology study, we trapped 46 turkeys using a standard walk in trap, and 40 more where a tarpaulin was slipped over the trap prior to removing birds.

Habitat needs of wildlife are important for science-based wildlife management. Further, these needs may differ based upon the ecosystem in which the species lives. Bobcat habitat use within the longleaf pine (Pinus palustris) forest ecosystem has received little attention.

Bachman's Sparrow Habitat in the Lower Flint River Basin, Georgia

Bachman's sparrow (Aimophila aestivalis) populations are generally declining throughout much of the Southeast, and habitat loss is suspected as the principal force driving declines. Therefore, we assessed the potential effects of current land use practices on Bachman's sparrows (BACS) within the lower Flint River Basin (LFRB). We then used a previously developed habitat model to quantify current available BACS habitat and used common landscape metrics to describe fragmentation of remaining habitat.
