摘要:We used ultrasonic telemetry to study post-release movement and dispersal of tournament-caught largemouth bass (Micropterus salmoides) in Lake Mead, Arizona-Nevada. Among 19 fish that survived for more than one week after release, none returned to its site of capture during a 43-day observation period. Dispersal was limited; twelve (63%) fish were last located less than 0.5 km from the tournament release site.
