Largemouth Bass Population Structure Changes and Harvest Under a Slot Length Limit
Effects of changing harvest regulations on largemouth bass Micropterus salmoides from a 254-mm minimum length limit and 10-fish daily bag limit to a slot length limit of 356-457 mm and later to a 5-fish daily bag limit were monitored on Calaveras and Monticello reservoirs, Texas. Electrofishing was used to monitor changes in size structure at both reservoirs and density as catch per unit of effort (CPUE) at Monticello Reservoir only. A creel survey was used to monitor angler harvest at Calaveras Reservoir. In both reservoirs, RSD 203-355 decreased while RSD 356-457 and RSD 457 increased....
