sought to quantify the freshwater mussel populations in
Grand Lake , Oklahoma to determine baseline information
for future commercial harvest and to assess the impact
of zebra mussels should they be introduced. A total of
11 species of mussels were found in the lake with six
species comprising about 96% of the individuals. It is
estimated that these six species represent a total of
148,096 individuals in the lake. The mussel populations
in Grand Lake are not dense enough to economically support
a commercial harvest.
