Predicting Long-Term Genetic Integration Following Stocking of Florida Bass (Micropterus salmoides) into an Arkansas Reservoir

Abstract: Management agencies within native largemouth bass (LMB; Micropterus nigricans) range across the United States regularly stock non-native pure Florida bass (FLB; Micropterus salmoides) or reciprocal LMB × FLB F1 hybrids to enhance angling opportunities based on public demand. Often, these stocked fish are introduced into waterbodies already occupied by LMB, which readily hybridize with FLB. This hybridization and resulting genetic integration of FLB alleles into the population is often considered the goal of stocking programs. However, managers have little...

Spatial Patterns of Florida Largemouth Bass Genetic Introgression into a Northern Largemouth Bass Population after Stocking

SEAFWA Journal Volume 9, March 2022

To enhance trophy potential of largemouth bass (Micropterus salmoides) fisheries, state agencies across the southeastern United States commonly stock Florida largemouth bass (FLMB, M. s. floridanus) outside of their native range into native northern largemouth bass (NLMB, M. s. sal- moides) populations. This practice has been ongoing for decades but spatial patterns associated with the spread of FLMB alleles in a reservoir after stocking are not well understood. From 2007–...

Evaluating the Genetic Response Following Introduction of Florida Largemouth Bass into Two Large Arkansas Reservoirs

SEAFWA Journal Volume 9, March 2022

The Florida largemouth bass (FLMB; Micropterus salmoides floridanus) is widely stocked throughout the southeastern United States with the intent of increasing the size potential of resident northern largemouth bass (NLMB; M. s. salmoides) populations. During the early 2000s the Arkansas Game and Fish Commission initiated an eight-year FLMB stocking program on selected reaches of DeGray Lake and Lake Ouachita in an effort to sat- isfy angler preferences. The goal of this stocking program was to achieve 40% of sampled largemouth bass in each introduction zone...
