Lake Mead Limnological Research Center: Technical Report Series
Department of Biological Sciences: University of Nevada, Las Vegas
Ninety-three wildlife agencies were surveyed for information on their attempts to improve fish habitat. In addition, an annotated bibliography including over 100 summaries was completed on:
1. largemouth bass cover requirements and preferences,
2. use and effectiveness of artificial cover,
3. aquatic plant introduction and species requirements for germination and establishment,
4. terrestrial plant introduction and species requirements for germination and establishment, and
5. nutrient exchange between sediment, aquatic plants, and water.
A reconnaissance of existing terrestrial and aquatic vegetation was completed in June 1986 including the production of a video tape of the Nevada shoreline of Lake Mead.
Cover of terrestrial and aquatic vegetation at thirty selected coves was measured in August 1986. Soil and lake sediment samples from these coves were analyzed for texture, organic matter content, cation exchange capacity, total nitrogen, and total phosphorous. Electrical conductivity and pH was determined for selected, samples. Water temperature, dissolved oxygen, conductivity, pH, and light transmittance were also recorded at each site. Eleven coves were observed seasonally for changes in aquatic and terrestrial vegetation.
Submerged Christmas trees were observed for fish utilization from June 1986 to April 1987. Berkley Fish Habitat Modules were observed for fish use from June to October 1986.
Conclusions and management recommendations are presented.
