I asked a question of Jay. I am quite sure that he was not working on the Columbia.They see summer and winter steelhead as bycatch in Columbia River spring Chinook fisheries.

There are times when the best available science is the determining factor in decisions made by government agencies and times when other things take precedance in decision making.Yup, I have been fishing for steelhead and generally playing around rivers that were heavily fished for over 40 years and the absence of dead steelhead is striking and in my mind absolute proof that nearly all steelhead caught and released survive. Even those caught with bait.
You mentioned 12 days of fishing and 10 dead steelhead. Fleet wide and season wide, that is no small impact.
I once heard a region 5 steelhead biologist specifically say that South Toutle river steelhead have no chance of long term survival in the face of in river commercial spring Chinook netting.
Half of the Wind river summer steelhead run is harvested in the 8 miles from Bonneville dam where there passage is recorded by pit tags and Shippard Falls where they are recorded again.( tribal netting) HALF the run!
Now I don't begrudge commercial and tribal fishermen their livelihoods, but in light of their impacts it is sheer idiocy to shut down any steelhead sport fisheries.
If this is science then science be damned and let's go with common sense.
While there is no empirical indication that CNR steelhead seasons in WA (which is virtually all wild steelhead in WA) is reducing the productivity of any steelhead population, it surprises me that conservationists who are also anglers embrace such extreme restriction of angling. Of course, if conservation is the only objective, then closing all the water all the time to all the fishing will achieve that. However, that isn't conservation so much as it's altruism. And that's not a bad thing; just not my thing.
I don't support petitions of this sort. Mainly because the evidence isn't presented. There is a whole world of sub-lethal effects that might be negative. But we can't or haven't measured them. I don't agree that the "cautionary principle" means we should simply not fish because we might have a negative impact. Fishing does have a negative impact. I can't prove it, but I'm fairly certain that the fish don't approve of it. I'm more interested in preventing the negative impacts that include killing so many fish that the spawning population is reduced such that the carrying capacity of the habitat cannot be used.
I'm so glad commercials get a pass. It's a way of life. You can trust the Gorton's fishermen. Such a green and noble industry.Completely unrelated, or not.....
B.C. trawlers dump thousands of salmon, depleting orcas’ food source: wildlife group
The group says the report estimates more than 20,000 chinook caught in the nets were dead and thrown overboardvancouversun.com
Commercial catches of steelhead in the ocean has been brought up a number of times. When steelhead smolt to adult returns plummeted in the early 1990s, ocean bycatch was suggested as the culprit by a lot of sources - mainly fishermen. And there was a lot of pirate style high seas fishing going on. A group out of Alaska even started up a patrol group in response because of salmon interceptions. I forget the name of that outfit. So WDFW even delved into the issue, which was pretty outside the box for that agency. The upshot, however, is that even though steelhead were being caught on the high seas, and even with unauthorized pirate style fishing going on, WDFW's best estimate, rounded up for any error, is that bycatch maybe accounted for 3% of west coast steelhead being intercepted. It seems that people are just very unwilling to accept that ocean productivity, at least in the NE Pacific, has declined. It could be a combination of ocean acidification, changes in coastal upwelling, changes in forage and forage composition, like lipid and protein balance among the available forage. Whatever it is might be complex and dynamic enough that scientists can't catch up fast enough to understand it. It's just so much easier to say that, yeah, high seas bycatch, because it's easier to blame a boogeyman that to accept of try to understand complicated situation.I disagree. The fishery I worked in was monitoring an in river Tribal fishery, so maybe it isn’t a great example of the mortality to steelhead due to nets in the ocean, but you can’t ignore the scale of fisheries across the entire PNW and how it would all add up. I also think the reporting numbers of bycatch of all types of fish isn’t accurate because it would look bad. The more I read about this stuff the more I suspect we have the fox guarding the hen house and the regulators aren’t willing to make the tough decisions. Just the easy ones like closing fisheries to sporties. I’ve worked with fisheries managers and I know how much pressure there is to keep commercial fisheries open. It is literally scary for them to consider closing a fishery.
It is more than, and it has. The Saltonstall-Kennedy Grant report on Skagit steelhead involved capturing a lot of wild steelhead for genetic data and acoustic tagging. These fish were handled more than ordinary CNR, but it also involved experienced anglers. The incidental mortality rate was less than 2%. I conducted a wild steelhead broodstock program on the Skagit in the late 1980s, which involved more handling than ordinary CNR too. And the incidental mortality rate was 2%. Smalma supervised a similar wild broodstock program on the Skagit and Sauk Rivers, and as I recall, he reported an incidental mortality rate of 4%. So the WDFW rate of 10% is conservative compared to empirical data.but I think 10% mortality is at least double the reality, and if that could somehow be proven with data,
In your eyes, why do we continue to use 10% as the mortality rate then?It is more than, and it has.

Best to err on the side of the fish, no?In your eyes, why do we continue to use 10% as the mortality rate then?
This happened a few years ago. It had to do with spring Chinook and the Columbia River. I sometimes like to use the term, "informed by science." There was some science available, but it wasn't conclusive. Ten percent incidental mortality was the number that NMFS, ODFW, WDFW, and the Columbia treaty tribes were able to agree on. Some times it's not science. Some times it's not common sense. Some times it ends up being the art of the possible. So WDFW adopted 10% statewide from what I can tell. In one case, one or more treaty tribes wanted WDFW to use 100% applied to a sport fishery, and amazingly, WDFW didn't cave. I won't say that 10% is here to stay in all cases, but I think it's safe to say that it will take a mountain to move it. And I don't mean a mountain of science.In your eyes, why do we continue to use 10% as the mortality rate then?
Yeah!Best to err on the side of the fish, no?
ONLY as it relates to sport anglers, for everyone else it's a free for all.Best to err on the side of the fish, no?
But the 2% value isn't representative of the general angling community participating in CNR fishing seasons. I thought I made the point that 10% had some science (lower river Chinook with scales not fully set are more vulnerable than fish with hardened scales; see Smalma's post above). Absent conclusive scientific evidence, which there hardly ever is, going with the art of the possible is as good as it gets in many cases.ONLY as it relates to sport anglers, for everyone else it's a free for all.
Using 10% when the actual number is 2% is not scientific.

Can you prove that 2%...scientifically? Or do we just continue the circular argument?Using 10% when the actual number is 2% is not scientific.
The poachers who go unsupervised and increase their impact when rivers are closed and devoid of true sport anglers.10% sounds good. Gotta account for the other sport anglers (tweekers and poachers).
Lower river spring Chinook caught by guys trolling herring with double hook rigs and letting the fish "eat" the bait.. I remember that study on the lower Columbia/Willamette.. it has absolutely no bearing on steelhead fisheries.But the 2% value isn't representative of the general angling community participating in CNR fishing seasons.

No, not ",poor me"Those guys get to do whatever they want!
That's not fair, mom!
I am all for fighting for oportunity. I have fought for it before. I am all for reducing commercial impacts. If there were a whole bunch of steelhead being netted in my local streams, I'd be writing my representatives.
The "poor me" stuff is hard to take though. Talk about emotion over logic. There is the perfect example.
