Invasion Description
1st Record: CA/Tomales Bay (1956, Hanna 1966, cited by Carlton 1979) Plantings were unsuccessful at establishing populations, but hatchery-based culture continues in California (Carlton 1979, Conte 1996). In Tomales Bay, spawning was observed, but no larval settlement (Leonard 1969, cited by Carlton 1979).
