Genetic Variation of Striped Bass in Lake Texoma

To determine if inbreeding was a cause of an apparent decline of large striped bass (Morone saxatilis) in Lake Texoma, striped bass sampled from four sites on the reservoir (n = 206), in the Red River below Denison Dam in 2001 (n = 58), and archived scale samples from Lake Texoma collections in 1978 (n = 44) were genotyped and evaluated at six microsatellite loci. There was evidence of weak population genetic structure among the collection sites. However, analyses of Hardy-Weinberg and linkage equilibrium within sites did not provide evidence of recent inbreeding within Lake Texoma....

Use of an Angler Incentive Program for Data Collection and Management of a Trophy Bass Fishery

One hundred and seventy-six trophy-size (?3.6 kg) largemouth bass (Micropterus salmoides), entered into a privately-sponsored catch-and-release program at Caddo Lake, Texas/Louisiana, were tagged and monitored to assess angler recapture rates, genetic composition, and their distribution within the lake. All largemouth bass program entries were scanned for tags to determine angler recapture rates over a 4-year period. Blood samples were obtained from initial entries and used to determine genetic composition using random amplified polymorphic DNA testing. Genetic data were used to evaluate...
