Observation Of Fish Attraction To Improved Artificial Midwater Structures In Freshwater

Artificial midwater structures constructed primarily with fiberglass panels and automobile tires were placed in an oligotrophic storage reservoir to determine the extent of fish association witb these structures. SCUBA observations were used to evaluate the effectiveness of the structures. Comparisons were made between these and previous structures used by Reeves et al. (1977). Six species of game fish were attracted; however, Alahama spotted bass (Micropterus punctulatus henshalli) and bluegill sunfish (Lepomis macrochirus) were the predominant species. Concentrations of harvestable spotted bass were noted throughout most of the summer months.
