Thanks Sarge and Danny for the info

Hi Nick,

Yes, that was most likely a lamprey. I don't know anyone doing research on them in Lake Washington, but they are relatively common out there. We get a lot of fish in our nets that either have lamprey on them or have lamprey marks (more common).

There is a lot of research on lamprey being done on the Columbia River. Yeah, bass eat 'em. 

If I run across any interesting info on Lake WA lamprey, I'll let you know.

Chris

P.S. Danny - stay outta my hood, flounder boy!

Nick,

Yes, your dad probably saw a lamprey....they are anadromous, meaning they travel to and from the ocean via Lake Washington (much like salmon) and the adults are parasitic, latching on to larger fish and sucking out nutrients. I'm not sure if anyone is doing research on them in Lake Washington here at the fisheries department, but maybe Chris knows. After all, he's the freshwater specialist....I just study flounder...

Tight Lines,
Danny

Hey chris I have a question for you. Is their any research going on about Lampreys in Lake Washington. Because my dad hit the sockeye opener and he claims he saw about a 7 in trout with a 8-9 in leach looking thing on it's side so I imediatly thought lamprey. Just wondering.
