There are, or were, lamprey in most of the stream around the sound. They spawn in freshwater and the "smolts" are about the same length as steelhead smolts (150 mm). Once in saltwater they become parasitic, but start out small. In addition to the Pacific lamprey, which were the common lamprey around here and are pretty good sized there is also the river lamprey. It is anadromous, too but don't get as large.

Like our salmonids, lamprey numbers are crashing big time.
