We have got 3 clipped chinook this year, the ODFW biologist cut the snouts out of them and sent them in for tests. They said they would send a card explaining where they come from. I dont know if I will get a card with their tight budgets, but he said most of the chinook are either BC fish, or California fish.
Two years ago I caught a Silver out of Tillamook that had a chip in its head. The checker cut its forehead out and said I would get a card telling where it was coming from. It took awhile, but around 4 months later I got this card saying that the fish was headed to Young's Bay.
I'm assuming that the adipose clip above St. Helens comes from just about any hatchery around, while the original question was more related to the adipose AND the ventral fin clip. I think...unless I missed something, TOC.
I have a theory on this, when the salmon interact with other schools in the ocean, some mixing occurs. you ever notice that the some fish shoot right up the rivers while others mill around going in and out of the mouth for a while.
I believe that some fish have better smell recepticals then others. so in the end some fish just follow other salmon up the river even though its not there spawning grounds. evidence to back this Ive caught brown (changing) kings in the salt. and caught a humpy and a sockeye in the samish river, a river that has runs of kings and silvers....DJ
Thanks for the info David. Hope to catch a few more. Good fighter and really good eating. I was just saying to my fishing buddies that I wish I could catch a Chinook on my new Lamiglass X80 and Shimano Tekota reel when it double over and the fight was on. Must of had some "Extra Sensory Fish Perception" that day.
