Do we have any fish that are catadromous here on the west coast?

The eels in the American river are the only west coast catadromous species I am familiar with. Doc may know of some "fish" but I'm unaware of any.

What is a catadromous spieces??

It's the opposite of anadromous. Fish that live in freshwater but move to saltwater to breed. Salmon are anadromous, but some fish (a few eels are all I'm aware of) are catadromous.

I ate some Barramundi at my sisters house the other day. Its a real popular fish in Australia and is catadromous. I didnt even know there was fish that did that but then again they are where the toilet swirls backwards. ;) I was reading up on them and I figured one of the sniffers was sure to know. What about Lampreys? I know they arent eels but ???

There are no catadromous species that were native to California. The American eel is an introduced species. *Lampreys are anadromous like salmon and steelhead.

Even the American Eel is not a true catadromous fish. They have been reclassified as facultative catadromy, meaning taking place under some conditions but not under others, or optional. They are native to the North Atlantic.
