Case in point, -farrel dogs, or dingo's were they not a domesticated animal evolved purposefully by man who then became wild through our irresponsibility? As long as man continues to be irresponsible in it's behavior involving our relationship with the earth given to us by G-d or for non-religious folks given to us accidently by nature(that is a scarry though- then why do we inheritally try to persue justice, good and compassion) we will continue to see adverse or damaging side effects of the many bad choices we make in neglect. Neglect is not love, and the result of not loving our earth it's creatures and people in a good way ultilmately could lead us down the road to our destruction. With that said, our ultimate goal should be to minimize and protect the resources that sustain us to the best of our ability. The steelhead, although an important sport fish to all of us, is just a thread in the larger web of the ecosytems health and life cycle. How do we know it is not possible that we will change or alter and better our systems of living in the future whereby our methods of survival will be less damaging then the models we now have? I like to think positively and optimisitically that we will figure it out. The example of Mt St Helens was an excellent one, whether you look at it from a "Nature" viewpoint or a "Spiritual" viewpoint. -It healed itself with time and a little concern from our part. One other note, if the dinosuars suddenly ceased to exist don't you think that nature or G-d intended it that way? Maybe we should be asking ourselves what the end will be or if we should care enough....

Cryingfish
In my opinion, it would produce the same type of spawner as that of the specie that it been cloned from. Since the patent specie has never before spawned and knew what is was to do, the same specie should inherently carry over the same spawning instinct.
That's how I see it. I may be wrong, but most likely I am not.
The prodigy of cloned fish should not be sterile because "they are" the same exact genetic make up as their parents (and their parents were not sterile). The more genetic samples they can get, the more diversified the genetic pool will be.
That way, you just don't have to depend on a single "clone" of any one wild fish; you have many "different" diversified clones' which in tern, should represent an entire run, or stock of fish.

Smalma......It is becoming clear to me that many of us use the same words, but have entirely different perspectives, based on what we see in our own environment. Habitat is one of those words that drives me up a wall, because of the extremist view points attached to that word. Another one is riparian zones, wetlands, etc. From what I have seen, the most volatile viewpoints are held by people living on lots in cities. The same people who demand that farmers can't sell their land to developers because city folks want to be able to see a cow. It is a NIMBY attitude, that precludes the possibility of farmers to improve their lot in life. And for this, the land owner gets to pay taxes for other peoples enjoyment, not his/hers. I see you are from Woodinville. I used climb through the barbed wire fences to catch bass in the farmer's ponds in Woodinville. Likely close to where someone's house is now........perhaps yours. Now you want to talk about saving the environment and the sanctity of the wild strain of steelhead. I have a suggestion to all who want to really do something substantial. Buy land along streams, lakes, wetlands.....pay the taxes on them (don't shirk the load off on the rest of us by jumping into a land trust) and then see that your land is in the best shape you can make it. That's saving something. I am a land owner rights advocate (fancy that ). I am also a wildlife enthusiast who has lived in Western Wa. for almost 50 years. I am not anti-gun, anti-growth, or anti-hatchery. The answer is simple......good stewardship. I take care of the stream that runs by my place and I get incredible joy watching the steelhead and salmon spawn there. I, personally, wouldn't damage that stream for anything, but that doesn't mean all who live by streams understand streams. I'm sure some of you folks see streams and rivers that have been trashed by industry and dense development. Fortunately, it is not that way here. There is no stopping people from moving here, and that is where the problem lies.....how do we deal with all the additional pressure on the sport we all love? I don't have the answer, but I do know it is not going to be solved by bickering. Best Regards to All and Happy Fishin'

Fun5Acres,
Were you replying to my response or Smalma? I live in Woodinville, he lives in Marysville. I rent a house with two other friends who happen to be fishermen. All of us grew up here(Redmond area -used to fish Bear Creek when there was a golf course) and are now 30yrs. I am a landowner however in Curlew, Wa near the Kettle River. By the way, I'm with you on the freezer thing! Best Fishing to you, DB

Steelnerves......geez, thanks for catching that error. My reply was not-so-much directed at any person, but rather at a few of the issues I view as continually problematic for me. The reference to Woodinville was only used to exemplify how the same areas that are now occupied by people used to be occupied by fishing holes, but I guess I blew it!

Cowlitzfisherman - Not sure that I completely understand your questions or that I can expalin my statements any clearer however here goes.
Our fish under constant selective pressures from their environments - those that are best suited for a particular condition are those most likely to survive to spawn and pass on those traits to future generations. As we make our rivers more alike - through confining the channels, diverting and/or regulatiing flows, etc - the fish become more similar. Thus the lost of diversity.
Lets take one simple trait - spawning timing. It is clear the timing of the spawning of our wild steelhead is determined in large part by the hydrograph of their watershed. Those systems whose hydrographs are dominated by rainfall (high lows in the late fall/early winter and declining flows from spring into the summer) have typical peak steelhead spawning of late March/early April (examples would coastal streams). Those systems dominated by snow run off (high flows in both the fall/early winter and late spring/earlysummer with declining flows occurring in mid summer) have peak spawning from late April (example Snohomish) or mid-May (example Skagit system). The reason of course is that spawning is timed so that the fry will emerge from the gravel so that gains from have longer rearing (early emergence) and high mortality due to excessive flows (need later emergence) are balanced to produce the most successful survival strategy. Thus the spawning is timed so that the fry pop from the gravel as soon as the spring/summer flows begin coming down. When man steps in a places a dam on a system to capture the summer run-off for power or water needs the downstream hydrograph is changed thus the fry survival matrix changes meaning the spawning timing changes. As more and more rivers are "managed" for our water needs their hydrographs become similar; ergo their fish become similar.
Your dinosaur example is interesting- they were successful for 10s of millions of years. However the prevailing theory is that a large asteroid crashing into the earth drastically and suddenly changed their habitats through dramatic climatic changes. They were not able to adapt and became extinct. My concern is that our alterations of our streams is becoming the steelhead's asteroid.
Fun5acres - I understand your desire for property right protection. It is certainly your right to advocate that position. However at the same time it is disingenuous not to acnowledge that allowing everyone to do what they please with "their land" has dire consequences to most natural resources.
The question becomes -How much are we willing to limit individual property rights to protect public resources. Nearly everyone would agree it is not in societies best interest for me to locate a nuclear waste site in my back yard ever though I may benefit greatly financially. We seem to differ on how much infringement of private rights is acceptable to protect fish, wildlife, water or quality of life resoources. Do we wish to keep those resources? If so how much? Are we willing to pay for it either in reduced rights or financial reimbursements? Those questions keep boards like this lively!

Fun5Acres, No harm taken. None given. Good thoughts. smalma might be right about good land owners like yourself who care --and the others who are either uneducated, unaware or worse neglectful and the worst -greedy and harmful. To everyone else, It's nice to see the passion flowing out of everyone on such important things. Maybe we should invest more time and energy into "Virtual Steelhead Fishing"??

Smalma
Thanks again for both your reply and impute!
Once again Smalma, you have brought to this boards attention, something that really makes sense to me, and may just explain WHY our wild steelhead runs may be declining and possibly on their way out (for the short term anyway!). I don't know if you even knew that you may have hit the nail right on its head!
You said; "Your dinosaur example is interesting- they were successful for 10s of millions of years. However the prevailing theory is that a large asteroid crashing into the earth drastically and suddenly changed their habitats through dramatic climatic changes. They were not able to adapt and became extinct. My concern is that our alterations of our streams is becoming the steelhead's asteroid."
Very interesting point that you have made! Do you think that it just might be possible that our fish (wild native steelhead) are now experiencing a small form of an asteroid called "El Nino"? It would sure make sense to me, especially after reading your latest reply and explanation about; "It is clear the timing of the spawning of our wild steelhead is determined in large part by the hydrograph of their watershed. Those systems whose hydrographs are dominated by rainfall (high lows in the late fall/early winter and declining flows from spring into the summer…)".
I can see a direct correlation between declines in our steelhead returns to the increasing number of the El Nino events. Just maybe, that may be part of our problems and we are just too blind to even see the correlation between the two. The changes that may be occurring are NOT as sudden at your asteroid theory, but never the less, they are continuing to change the climate all over the world. It's just possible; that we aren't looking at the big picture and that we are only looking at a much smaller picture called local "habitat". If the steelheads aren't finding the right water temperatures in the oceans, and they aren't getting the right food chain either in our oceans or their streams to support their cycle of life, Isn't it just possible that we are not seeing the whole picture here?
I guess we tend to go after the "habitat" issue, because it's in our own "back yards" compared to knowing almost nothing about what really "happens to steelhead" when they leave our coast and begin their final growing cycle in someone's else's habitat. The more I think about it, the more I am concerned that we may be barking up the wrong tree! I am not saying that "habitat" is not a key factor in steelhead survival; because it is. But what I am saying is; maybe it's not so much the habitat in our "back yards" to blame, as much as it may be the habitat in "the ocean" that is killing off our wild runs of steelhead.
It appears that we may be facing the doubled edged sword when it comes to habitat at home and habitat at sea. Steelhead can't make it with just one and not the other. So my question to you is; Does any of your research or studies show what the effects of El Nino has been, or is on seaward bound steelhead, or the natural production of native steelhead? Or are we all just making guesses on what we think is really going on?

Cowlitzfisherman- I have little expertise on ocean survival conditions or on most other areas for that matter. My limited knowledge is that various ocean conditions such as El Nino have been around for 1000s of years. As the ocean warms in El Nino the usable portion of the North Pacific for steelhead contracts (warmer water temperatures limit how far south the fish can forage etc). In addition to have less "pasture" the changing temperatures favors different species cause both forage and prey species abundances to vary. Bottom line generally for our steelhead survival goes down meaning poorer fishing in our rivers (for both hatchery and wild fish).
These types of cyclic events as well as disaster such as the Mount Saint Helens eruption have been occurring forever. The fish have developed life strategies to sucessfully deal with these situations - the fact that they are here confirms that they have been successful. Generally the large disasters such as Saint Helens or forest fires occur in relatively small geographic areas (affect just a basin or two). Thus when one population is affected other nearby ones aren't which provide refugia for the species.
The problem is that these natural processes are occurring over relative long time frames (decades to centuries) while we generally look at things in much shorter periods. Comparing this year to last years or for us longer term anglers (old farts) how today compares to the good old days a couple decades ago. Our prespectives aren't the same as Mother Natures.
Of course the larger issue is the nature of the disasters of which I spoke. While it is true that they tend to localized rather than global such as the dinosaurs asteroid we as the human species have been attacking our streams at a global level. Most of our streams are being confined, damed, logged, filled, etc. This of course means that when these poor survival conditions cycle around (El nino) our alternations of the habitat reduce the probability that the fish will have safe or productive refugia.
It appears that we are testing the resilency of the populations to a level near seen before. I for one am uncomfortable with this form of Russian Roulette on a resource that I care deeply about.

One more quick question. Does anyone really know just how long steelhead have been native to Washington State (i.e. 200, 500, 1000 years or whatever) or how old the "specie" steelhead is?
That too may help us (including me) to understand why the steelhead populations are continuing to head downward. Could it be that they (steelhead) are just beginning to start an end to a life cycle in fish evolution?

Cowlitzfisherman- Further taxing my limited knowledge.
Without doing any research as I recall the first of the salmonid type fish show up in the fossil records maybe 50 million years ago. The first of the salmon/trout type was around maybe 10 million years ago. Likely evolving in the Arctic which at that time would of had a climate somewhat like todays pacific Northwest conditions. Folks believe that the first of the "modern" trout to colonize the NW was cutthroat, followed by the redbands and then todays rainbow/steelhead. As this region expereinced glaciation various populations came and went as their basins were alternately were buried and exposed by ice that at times may have miles thick. As recently as 12,000 years ago the area north of Southern Puget Sound was ice covered. As that ice age ended and the ice receded our streams were colonized from populations found to the South, interior of the upper Columbia and/or the Queen Charolate Islands north of Vancouver Island.
I may have some of the details incorrect as my memory is what it was once. However believe the above will give you a sense of how long these animals have been our streams.

Looks like this is becoming a franken World. What the h*&l is goin on? I am sure not ready to share my fishing hole with Frankenstien. I can just see the need for extra clone fisherman to keep the clone fish in check. I say lets sleep on it for a few thounsand years until our brains are more developed and our morals and values upgraded.

I guess that I would have to be in favor of extracting D.N.A. for the use of cloning fish in the future if necessary.Of course you would need as many samples as possible,so you could still have the diversity in the fish.
What if we do everything possible to provide the best possible habitat for the fish,and they still become extinct.Face it we dont know enough about ocean conditions.There is little we can do to regulate the weather patterns.So the only real control we have is in the habitat of the streams they live in.Tops this is 1/3 of the equation.That leaves a lot of room for disaster in all other areas.
What I'm getting at is that no matter how much habitat enhancement we do there is a possibility that these runs could be totally wiped out.Who knows when,maybe soon,maybe thousands of years down the road.
Why not have the basis for starting new runs or improving the runs we have,once the science of cloning is perfected.The habitat in the rivers and oceans recover,if possible,and the weather patterns decide to cooperate again.
Its like money in the bank.(I hope) If we save now maybe we can have some for seed later.If we dont save now,how could we ever have the seed for later.Once its gone you cant go back in time to get it.
Hopefully the worst case scenario never happens.The runs rebuild on there own,and we dont have to face such a dilemna.But what if? Kinda thinking outside the box I guess.
Mooch, Your remarks really aroused my curiosity.I was about to argue your point about the Toutle.I guess actually I am.But in the same sense maybe supporting it.
The Toutle wasnt really left alone.Remember the sediment dam.All the silt thats built up behind it.Imagine what could have happened if that dam wasnt built and all that silt was allowed to flush out of the system.
There would have been a need for a lot more dredging on the Cow. and Columbia.(probably needs it again in the near future anyhow)but the whole Toutle valley might not be inundated in silt,like it is now.There would probably be a whole lot more natural habitat and spawning grounds to allow these runs to rebuild like the should.
There is very little fishing opportunity for steelhead on the mainstem Toutle. I think it is more of just a passage to streams and rivers that were relatively untouched by the eruption of Mt. St. Helens.
The South fork Toutle.and Green river were for the most part out of harms way during the eruption and flows that followed.The only stream that I remember for sure that supported fish runs and dumps into the North fork and was also relatively untouched was Alder creek.There May have been some others,but its been so long I honestly dont remember.
Maybe the fish that were in Alder creek at the time of the eruption have reproduced enough to help rebuild runs in the n. fork.Maybe some of the Green and S fork fish helped rebuild the runs.I dont know.
I would be curious though just how many fish are transported over the sediment dam.How many go further upstream than Alder creek.How many spawn naturally,in the N fork compared to Alder creek.
I guess I'm curious if its rebuilt itself as well as you say,or maybe were led to believe.As far as I know we arent allowed to fish above the sediment dam.Why not if the runs have recovered as mentioned. C.N.R.?
Maybe somebody on here can give us the #s or tell us where to get them. Or have some answers to the other questions.
Kinda long winded,kinda scattered,kinda off track. But you brought it up,and I,ve been curious for many years.So I couldnt resist. Maybe good for a new topic on this one?

Gents,
Cloning, pure and simple, is just another means of ARTIFICIAL PROPAGATION of a species. With regard to steelhead, this issue boils down to two basic, but separate, issues which are:
1. Is artificial propagation of steelhead necessary or desireable for the propagation of the species?
2. Should cloning be used as a means of artificial propagation of the species?
With respect to cloning, it is possible to address question #2 without having to answer question #1, as it then becomes a discussion of BMP, or "best management practice", or best scientific practice if you will. Remarkably the answer to this question is not at all unclear, because whether cloning becomes a more effective means of animal propagation in the future or not, it will never be a preferred, or even desirable, means of propagation of steelhead. No, not even if cloning acheives its full theoretical potential.
The reason for this is simply because even in the best case scenario, cloning which is "asexual reproduction" has INHERENT drawbacks to hatcheries or artificial insemination which is"sexual reproduction". First of all it is (and always will be) less efficient. Secondly, the total lack of genetic diversity is a serious (actually monumental) drawback. Thirdly, cloning offers no benefit to the currently available best management practices of "sexual repoduction" and in no way offers a solution (even the potential for a solution) to the problems presented by the current BMPs (which is hatcheries today). Fourthly, it has no unique or special benefit over any other techniques currently available for the artificial propagation of steelhead, as a species. To an individual, possibly. To rephrase in simple english: If hatcheries are inefficient, cloning will always be more inefficient. (Sorry George Jetson) If we can't afford hatcheries now, you can forget about cloning ever. If genetic diversity and vigor is a problem with hatcheries today (and this is a big one folks), cloning doesn't even begin to compare.
And this does not even take in to consideration the other mitigating concerns about cloning as they involve the first question and whether it is something that is needed or even desirable. It simply has exceedingly limited potential for the artificial propagation of steelhead, now or in the future.
While question #2 is very easy to answer, question #1 is far, far more difficult. Regarding question#1 however, please understand that I am NOT promoting hatcheries as part of this discussion. But for those of you that are in favor of artificial propagation, you must understand that cloning is simply not a viable option, now or in the future. For those against artificial propagation of steelhead, cloning is a topic that has the potential to detract and deflect from the significant and pressing issues that are currently being addressed with regard to wild fish. It may be fun to mentally masticate this topic but it is a RED HERRING. It would be sad to think that in our ardor to solve all the problems of the world by the idol that is technology, we would once again fall hook, line and sinker for the assurances that were made when the dams were built. Yes, of course we needed the power, but did we really believe it would be free, with little or no impact on the fish resource, when they told us that "future technologies" would mitigate the impact on the resource. They are still trying (desparately now) to deliver on those promises today, crying out "where is our god now?".
Forget the cure, cloning is not even a panacea!

Back to reality here folks.
The technology to clone fish does not presently exist. Assuming the cost were similar to cloning mammals (cats dogs, sheep, people), something in the range of $200k to $1000K per animal is the expected price tag.
For a low tech solution to the problem, to achieve more genetic diversity in hatchery fish, why not select for it directly. In a sense hatchery steelhead and salmon are just domesticated animals. Why not do what animal breeders have been doing for thousands of years and select for desirable traits. Why not only spawn those hatchery fish that have desirable traits? ie stronger, bigger or more aggressive fish?
Just my $0.02
