Unfortunately the striped bass have taken a stronghold in many of the California Estuarine environments that are home to threatened steelhead juvenile populations,several on the central coast of California. Unfortunately I don't see them being eradicated. There have been stripers present here since the 1970's that I know of ,but it wasn't until around a decade ago that the population began to boom. I believe there are spawining populations in at least 1 of these rivers as fish have been found in upper stretches. These rivers are highly regulated,and so the fishing season for them is extremely limited. It isn't looking good for California central coast steelhead.
