WAKASAGI INFO
Wakasagi - This small dynamo is a substantial part of the bait fish forage available to bass in a number of California reservoirs, including but not limited to, Lake Almanor, Butts Lake, and Lake Oroville. Wakasagi (Hypomesus nipponensis) were intentionally introduced in 1959 from Japan by the California Department of Fish and Wildlife as an experimental forage fish for trout. The wakasagi were stocked in California in Sly Park Reservoir, Dodge Reservoir, Spaulding Reservoir, Big Bear Lake, Dwinnel Reservoir, Shastina Reservoir, and Freshwater Lagoon in 1959. They were then stocked in Lake Almanor on the North Fork Feather River in 1972. They have since migrated downstream from Lake Almanor to Lake Oroville.
NOTE: the species is not found today in all waters historically stocked and it has been observed throughout the Sacramento-San Joaquin system and as far south as Diamond Valley Lake in Southern California.
