Hatchery Marked Pinks??
« on: September 14, 2014, 07:54:19 PM »

Just wondering if there is such a thing, a coworker mentioned he was catching them a few weeks ago on a North Vancouver Island river.   I did not think hatcheries ever marked pinks, anyone have info other wise?

Maybe an accident. Seen lots of clipped springs this year.

Or maybe up your co-worker doesn't know how to identify fish properly.

Not to derail the thread but...  In Canadian waters, don't they only clip the springs that are encoded with an electronic chip in the heads?  A guide in Kyouquot who does part time DFO and hatchery work, was telling us that.

They also clip some springs in rivers that have small wild runs. You will see some rivers only allow retention of hatchery marked springs.

Most of the information posted above is wrong. All of the salmon species have been marked at one point of time for a variety of reasons. Endangered sockeye in the Chilliwack system are adipose clipped, coho smolts from DFO hatcheries are adipose clipped but generally not Coded Wire Tagged unless they are doing survival / exploitation studies. Chinook from Canadian DFO hatcheries can be adipose clipped and CWT. American chinook are generally adipose clipped only but can be CWT as well. Chum can be CWT and / or fin clipped. Pinks can be adipose or fin clipped, especially if they are from net pen programs ( assessment reasons). Pinks are hard to do but can survive quite fine if handled properly. Did this with Squamish pinks back in the late 80's so don't rule out this happening in other places.

Thanks bkk, always appreciate having you and others working in this field providing accurate answers. :)

Definitely possible if they are stocking them there (esp. local volunteer hatchery) although its more likely he misidentified his catch. Smaller female coho that aren't completely chrome anymore can look like female pinks and can be a bit hard to tell apart if you don't know what to look for. Caught what I thought was a hatchery clipped pink on the Vedder a few years back but it turned out it was a Coho. Could tell by the white gums, black tongue, and lack of larger spots. Since it was clipped (and not a Sockeye), I knew keeping it didn't matter either way.

could have something to do with one of the net pen projects on Vancouver Island. They do one at Nanimo in Depature Bay that had fish return to it this year. Just a guess though
