Dealing with Largemouth Bass Virus: Benefits of Multi-sector Collaboration

Largemouth bass virus (LMBV), a recently identified pathogen, affected largemouth bass (Micropterus salmoides) in the southeastern United States beginning in the 1990s. Concern about the impacts of this little-known pathogen on largemouth bass populations, effects on fisheries management, and the need to provide anglers and the media with consistent and accurate information prompted a private organization (Bass Anglers Sportsman Society) to invite managers and researchers from state and federal agencies and universities to a series of five annual public workshops beginning in 2000. These...

Texas Response to Largemouth Bass Virus: Five Years of Monitoring Freshwater Hatcheries and Fisheries

Since largemouth bass virus (LMBV) was implicated in 1998 and 1999 as responsible for fish kills in some of Texas' most prestigious bass fisheries (Fork, Sam Rayburn, Conroe and Toledo Bend lakes), the Texas Parks and Wildlife Department (TPWD) has taken an active role to better understand this emerging pathogen. An extensive statewide survey of 49 water bodies conducted in 2000 coupled with continued monitoring of bass fisheries has detected LMBV in 23 water bodies within nine of 13 water basins in the state. The virus has also been detected at TPWD freshwater hatcheries and procedures...

Striped Bass Brood Stock Management in Texas: Planning for the Future

Striped bass (Morone saxatilis) were first introduced into inland waters of Texas in 1967. Since that initial introduction, 44 inland waters within the state have been stocked with over 120,000,000 striped bass and the species has become the fourth most popular sport fish among anglers. Although successful striped bass fisheries have been established in numerous Texas reservoirs, there are few self-sustaining populations, and maintenance of the fisheries is dependent upon hatchery stocking programs. The high fecundity of striped bass renders the species vulnerable to genetic drift and...

Effects of Stocking Regime and Harvest Regulation on Florida Largemouth Bass Stocking Success

During a 2-year period, 250,000 Florida largemouth bass fingerlings were stocked among the endemic northern largemouth bass population of Tradinghouse Creek Reservoir (1985 = 185/ha, 1986 = 123/ha). We used electrophoresis to estimate proportions of Florida, northern, and Florida x northern intergrade largemouth bass within pre-stocking, stocking-year, and post-stocking year cohorts. Ages of largemouth bass were determined by examination of whole otoliths. The proportion of Florida phenotypes within the stocking-year cohort was not increased when the stocking rate was more than 50/ha...
