The first segment, July 1-31, will be an "all salmon mark-selective coho fishery" in which anglers will be allowed to retain only coho with a clipped adipose fin.

Salmon fishing won't be 'lights out'

Rainbow trout have a speckled back, and most but not all hatchery rainbow trout have had their adipose fin - the fin on their back, between their main, or dorsal fin, and the tail - clipped.

Anglers, of course, may target only hatchery-reared "springers," marked by a clipped adipose fin.

It's a selective coho season, which means a limit of two salmon per day that have a healed adipose fin clip.

The bulk of the 2011 ocean coho season in waters south of Cape Falcon, near Tillamook, will operate under the now-familiar "marked-selective" rules, meaning only coho with a healed adipose fin clip may be kept.
