Mississippi Silversides, Menidia audens (Atherinidae), Established in California

Abstract

Menidia audens were introduced into Upper and Lower Blue Lakes, and in Clear Lake, Lake County, during the fall of 1967, as a result of previous study indicating a high potential for this species as a biological control agent for aquatic midges, and as a forage species for game fishes. Although the species has not as yet been recovered from Upper Blue Lake, it is doing well in Lower Blue Lake, and has already become a predominant component of the fish fauna of Clear Lake.
