David L: Two eanut butter jars of plankton that he collected at Cowlitz were predominantly crab zooea, but also a lot of Calanoids.

David L: A while ago there were some small fish in Cowlitz that looked like salmon smolt, maybe. Yesterday in Deer Harbor about 5 pm I got a good look at a variety of fish on the surface in the floats at Deer Harbor Marina. One group looked very like salmon smolt, a couple of sizes: small (3 inch-ish) and slightly larger (under 6-ish). I'm not good at surface identification, and I really wanted them to be herring (nope). Perhaps they were salmon. I'm pretty convinced they are. They are greenish/blue, small dark marks on the tail and dorsal, not much pattern on the top (pink/chum?). Of course I want them to be the last vestiges of Spring run chinook. That's asking a little much.
Otherwise things are intense underwater in Cowlitz: big groups of various sea birds, a biologic film on the surface and God knows what underwater... exactly 14 days after all those tiny eggs. We'll be plankton sampling today... this should be good.
