- Abstract
In 1999, the Southern Division American Fisheries Society Reservoir Committee conducted a survey to identify state agency goals, uses, and perceived effectiveness of artificial habitat structures in lakes and reservoirs. Of those states surveyed, 82% conducted some type of enhancement. In most states, 20% percent of water bodies received enhancement although respondents usually believed a larger portion of lakes and reservoirs (>40%) needed enhancement. Although several objectives were identified, most structures were placed to attract fish to increase angler catch rates. When asked to rate the effectiveness of structures on a scale of one (very satisfied) to five (very dissatisfied) with regards to agency objectives, most structures received a mediocre rating with mean values lying between two and three. Although abut 60% of states reported evaluation of structures, evaluations usually were testing for differences in fish abundance or angler catch rates between habitat structures and control areas. Few studies documented effects of structures on fish recruitment or population size. More studies are needed to assess effects of habitat structures on recruitment and abundance of sport fish in lakes and reservoirs. Readers are referred to an online habitat enhancement manual for more information on structures reported in this survey.
