AbstractThe water quality parameters measured were not limiting available habitat nor contributing as a stressor inhibiting growth of largemouth bass (Micropterus salmoides) in Mittry Lake, Yuma County, Arizona. The decline in the general condition of the largemouth bass fishery appears to have resulted when artificially high growth rates and condition factors caused by unusual flow conditions and exceptionally large amounts of nutrients or forage began to return to normal. The data from Mittry Lake supports the fact that largemouth bass are habitat and forage generalists. Largemouth bass successfully exploited all types of conditions within the lake. Movement of largemouth bass in Mittry Lake suggests the existence of sedentary and mobile segments of the population. It appears unlikely that electrofishing causes the same incidence and severity of injuries to largemouth bass as it does to salmonids. MI of the hemorrhages and spinal damage found in electrofished largemouth bass were minor.
