Mass of Mississippi Silversides from Clear Lake, California
The Mississippi Silversides was introduced into Clear Lake California in 1967, and they proliferated. The fish shown here were collected with a small seine. A maximum of 90,000 fish were collected with a single 10-m seine haul in 1980. The silversides are an important zooplankton predator, and are also an important forage fish for bass, crappie and a variety of other fish in the lake.
The taxonomy of the species has been revised several times with the following names being used:
