I understand the concept of parental based tagging but don't see how this alone would be applicable to sports anglers who would release wild fish. Surely a visible mark identifying the fish as hatchery origin is necessary, no?clipping or parental based tagging...

All hatchery fish clipped.
End of story.
Will be great to see how awesome our "wild" populations are after a few brood cycles.
Ya - I'm not seeing the priority on tagging specifically for catch and release, Dave. Maybe you can explain that one?
Well if I understand you point - you would like adipose clips so you can retain more hatchery steelhead and coho that are hatchery fish but not clipped that show-up in your watershed.
Wrt PBT - I believe I am seeing it from a larger perspective - looking for what a "measure of success" is for stock enhancement for all fisheries. There are some glaring issues with large-scale, long-term stock enhancement. Some of those issues could be mitigated somewhat using PBT while changing both feeding regimes and release strategies @ low-cost to the hatcheries - but some $ needed for increases in DNA work.
No what he’s saying is that most anglers think they catch and retain wild fish that are really just unmarked hatchery fish. That of all hatch fish were marked anglers would get a huge eye opener on how rare an actual wild fish is. In some areas/times catching a wild fish would become a pretty rare event.
for example on WCVI otolith marking showed that the hatchery catch was 50-80% depending on area and times including off shore. How ever adipose mark rate was 0-30% depending on area and time. For chinook
First, it's not me who wants hatchery fish, if it was my decision the steelhead component of the Chilliwack River hatchery would be axed and the roughly 100k it costs be allocated to habitat restoration and maintenance.Well if I understand you point - you would like adipose clips so you can retain more hatchery steelhead and coho that are hatchery fish but not clipped that show-up in your watershed.
