Yes, you will hear from me that this bill will have dubious benefit to most of our wild steelhead populations. Have followed this idea for nearly 50 years and have seen little evidence that such programs lead to "healthy" steelhead populations.Great idea on Bill 6241. Brood stock steelhead funding. Works great in Oregon. Badly needs to be done in WA.
Of course now we will hear all the “can’t be done, doesn’t work know it all’s” .
Too bad that they have the program, yet continually reducing the number of smolt releases. Return numbers are not that great the last few years for winter steelhead.Yes, you will hear from me that this bill will have dubious benefit to most of our wild steelhead populations.

Yes, many in Oregon claim great success but to date I have virtually no monitoring data that supports those claims.
And Yes, for those that get to collect the brood stock is satisfying and generally fun.

Are there any as hopeless as the willfully ignorant? I will say that it is hard to learn if you don't pay attention. Did anyone here say that a broodstock program with chum salmon doesn't or will not work? I don't think so. Here's why: Chum salmon are not steelhead. That's important because hatchery culture for the two species is different. Think on that for a moment if you will. Chum salmon brood are collected, the eggs incubated and hatched in one of several times of artificial production facilities (many have been tried). The fry are then immediately released into a stream or held are reared artificially for a few weeks and then released. Contrast that with collecting steelhead broodstock, artificially incubating, hatching, and then rearing the offspring for 12 months or longer prior to releasing them into a stream.I guess i had better go run up right now to the Wallace hatchery and tell them the Brood stock program they are doing with Chum salmon doesn’t/wont work !
OH WAIT ! It IS working, with great results. And of course the Snider creek program. Oh No it worked Too !
All of this! The other point I've been mulling over on the chum vs steelhead broodstock are the factors limiting their success. Chums are heavily affected by our increasingly frequent november/December flood events. It both disrupts their ability to find gravel while it's happening and scours out what has already been laid.Are there any as hopeless as the willfully ignorant?

Why does this difference matter? One artificial factor affects both species about the same: spawning pairs are selected by humans rather than the fish selecting mates naturally. The extremely important difference, however, is that when a salmonid fry emerges from the gravel, it divides its time between foraging and seeking cover from predators. In a hatchery setting a fry can focus on foraging and existing among a crowd of its peers, but learns nothing about avoiding predation. In the case of the chum salmon fry, they enjoy that luxury for only a few weeks at most, and then it's out into the natural world they go. And woe unto any that focus solely on foraging and not avoiding predation. The broodstock steelhead, on the other hand, spends all of its first year focused on foraging (when the hatchery feed truck drives by) and nipping at the fins of its brothers and sisters, and never learns to give a thought to avoiding predation because there are no predators in the hatchery environment. Upon release at age one year plus, the hatchery steelhead smolt enters natural environment full of predators in both the freshwater and marine environments. Like most life history attributes, foraging for food and trying to avoid predators and heritable traits. After a year or so of hatchery living, the young steelhead has no idea that he should concern himself with predator avoidance - until it's too late. And then, well, it's too late.
And this Skyrise, is the one major reason why a broodstock program can produce chum salmon adults more effectively than can a steelhead broodstock program. You mentioned the Sol Duc Snider Creek broodstock program and claim that it worked. I guess we should define what "work" means. Can a wild steelhead broodstock program produce returning adult steelhead? Yes, it can. That has been verfied with several projects of which I am aware. Does a wild steelhead broodstock program result in subsequent net increases in wild steelhead populations? Not in any of which I am aware. This doesn't mean that it couldn't, but no program sponsor has expended the kind of monitoring that would be necessary to substantiate that it does. What we know is that wild steelhead broodstock programs can return subsequent marked (hatchery/wild) steelhead that can be available for harvest, if the fishery managers so wish. In those cases, that means that the wild adult steelhead were "mined" from the natural spawning population such that there are fewer natural spawners from that population to spawn. The surviving offspring from those broodstock are made available to treaty and non-treaty harvesting, with the unknown number of those fish mingling among other natural spawners that that return year.
The benefits and liabilities go something like this: Those broodstock spawners add to the natural spawning population. However, we have learned that even a single generation of hatchery culture changes the survival prospects of fish. So when an H x H (hatchery fish mates with another hatchery fish) mating occurs, the survival prospects of any fry that are produced are significantly less than that of an W x W (wild fish mates with another wild fish) mating. And when a H x W mating occurs, the survival prospects of resulting fry are also less than from a W x W mating. Admittedly, there remains a lot to learn about these aspects of fish culture and natural fish production, be we have learned enough to know that the benefits are far less than what the wild broodstock program proponents would have us believe.
Now maybe you have a better idea why some of us who have been down this path are not as enthusiastic about another wild steelhead program as you appear to be.
