Now they have actually identified some hitchhikers on the dock that
only come from the western Pacific so we are sure where it came from.
Now the worry is that some of these things may be invasive exotics.



--------------------------------
Probably no more invasive things than we already have.

The scary thing about invasives is you don't know how much trouble
they will be until they are here. It could be a subtle thing that ends
up screwing up the Dungeness Crab harvest or something.


------------------
We have most of the nasty invasives already. Ballast water mostly. They
now have to change ballast water a couple hundred miles out to sea now.
Biggest local problem is the Mitten Crab. They breed in the brackish waters
and eat most everything Last couple years have not been as bad. We think
the local sport fish and sturgeon have acquired a taste for them.
