2010 Cheakamus River adult chum salmon study
« on: October 14, 2010, 04:02:17 PM »

ATTENTION ANGLERS

BC HYDRO, as required by their Water License on the Cheakamus River are monitoring annual population levels of chum salmon in the Cheakamus River.

As part of this study, fisheries technicians will be capturing chum adults and applying transmitters and a brightly coloured “disc” (attached below the dorsal fin) to a number of chum adults each year from early October through November. Two types of transmitters will be utilized:

1) PIT TAGS: This transmitter is applied in to muscle tissue just below the dorsal fin. When cleaning any fish retained for consumption please remove this tag from the flesh.  All fish tagged with “disc tags” will have one of these transmitters.

2) RADIO TAGS: This transmitter is inserted through the mouth and into the stomach. Only 1 of every 10 fish with a disc tag will also have a radio tag. Radio tagged fish will have a thin plastic-coated wire antenna that hangs out of the mouth and can be mistaken for fishing line. PLEASE DO NOT PULL ON THIS WIRE OR REMOVE THE TAG.

Following tagging these chum are tracked throughout the river to identify spawning areas and run-timing. This is done with hand held and stationary receivers at various sites along the mainstem and side channels of the Cheakamus River. Electronic enumeration of chum adults into side channels (BC Rail, Tenderfoot, NVOS channels and Moody’s) in conjunction with tagged fish distribution will allow for the development of an annual chum adult escapement estimate to the Cheakamus River.

Anglers are requested to:
  • Report capture of tagged fish to InStream Fisheries Research Inc.
  • Release tagged chum adults with a minimum amount of stress.
  • Report tags found or in dead fish to InStream Fisheries Research Inc.
  • Return Radio transmitters to Tenderfoot Hatchery (Midnight Way) or contact InStream Fisheries Research Inc for mailing address.

Nice to here there is a study being done by hydro . I take it they can afford it . To bad there were more done around the lowermainland and valley rivers done by hydro  :P. ( or is there , I'm just not seeing it )  8) . I recall going way back , a couple locale rivers with radio tagged chum on them . The Squamish area rivers have allways been well maintained . Fisheries officers are always not far away if there are any problems . I see them driving and hiking there all the time . Good for BC Hydro though . I will be aware now to handle a tagged chum not to stress them out and release quickly .

Just to add some more information to this.

This study includes netting and tagging approximately 1,000 fish at two locations on the river.

The two locations are the Stables (down near Canadian Outback Adventures) and the Gauge Pool at North Vancouver Outdoor School.
