The largemouth bass (Micropterus salmoides) population in South Mill Creek Lake, a centrarchid-dominated, eutrophic small impoundment in West Virginia, was managed under a 305-mm minimum-length limit until 2007. Under this regulation the population was typified by consistently low proportional size distribution (PSD) values, low quality-length CPUE, excessive juvenile recruitment, and poor length structure. Therefore, in 2007 a protected slot limit (PSL) regulation (305–406 mm) was implemented to shift the size structure of the fishery. Spring (May) boat...

Brook trout (Salvelinus fontinalis) have been extirpated from many karst-geology streams in West Virginia; however, the causes are not fully understood. Specifically, the impact of calcareous precipitate (marl), which is common in hard-water environments, has not been evaluated as an im- pediment to juvenile survival. Accordingly, two lab-based studies were conducted to determine if brook trout egg and alevin survival is inhibited by marl. In the first study, three aeration treatments were applied to water from a limestone spring source (13–14 C; ~300 mg L–1...
