    Using a video capture system, we take pictures of fish to see how many there are of the different species day after day using a fishwheel. The fish are never held and slide right out of a chute back into the river. We do a bunch of other things also

    The left picture below is a link to a shortened section of a video file made one fall day when the whitefish were running strong. What you are looking at is about 10 pictures or frames of each fish that the fishwheel caught in a 6 hour period, with all the time removed when no fish were being caught. At the end of each fishing day we have a 24 hour video file just like this 6 hour file. We can count species, do some sizing, spot tags, and produce video archives that are often gone back into for numbers of reasons years later.
    The right picture below is a link to 6 chum getting caught in one basket of a Rapids subsistence fishwheel during the big fall chum run of 2005 and is there for fun viewing (20 MB, 3 minute version available under on left). The Fish Friendly page has a short, low impact video wheel clip and a narrated non video Tagging wheel clip on it also.

Project Objectives

1. To provide daily fish wheel/video catch per unit effort (CPUE) data on Chinook, summer chum, and fall chum salmon.
2. To provide daily fish wheel/video CPUE data on migratory whitefish.
3. To continue improving fish-friendly fish wheel capture techniques and equipment
4. To continue developing and using our present methods for adjusting raw catch data that takes into account factors such as river discharge, fish wheel catch efficiency and small versus large size Chinook yearly variations.
