I wonder why we don't have Brown Searun Trouts here in the PNW.

With all the "non-native" fish we have intermingled in our streams and lakes I wonder how come there aren't any Sea-run Browns round these here waters. Does anyone know of a good explanation? Is it food source? I take it our climate is good enough no? Maybe our river systems don't support their spawning habbits? Been curious about this.

Really? What makes you say that?

Also, Evan why do you say that?

I'm neither pro or con, just generally wondering.

Think they are too voracious and would decimate other fish populations even SRC populations?

Even more interesting is why we don't have confirmed, sustained populations of Atlantic salmon. With the rates of losses at net pen operations in Washington and off B.C., there have been hundreds of thousands/millions of introduced fish, but I haven't heard of a multi-generational population that have appeared. I had read that there were some Atlantics found spawning in a Vancouver Island river, but I have not read if the breeding was successful, if the juveniles survived, or if any of the smolts made it back.
Onto the bigger question, I share the view that we should not introduce non-native species. Not only are there concerns with introduced diseases, etc., but they can disrupt co-evolved ecosystem relationships in unpredictable (usually negative) ways.

Once upon a time, millions of juvenile Atlantic salmon were stocked all over BC. Between that and the pen escapees, there have been very few sightings of what appear to be adults returning form stocking or juvenile fish that resulted from breeding. The Cowichan seems to come up.

Here is a timeline, not verified by me, but seems in accord with what I have read before.

We have them -- we just call them bull trout!!

With our variety of the native anadromous stocks there just may not be much room or niches for a sea-run brown to take advantage off. As pointed out by Cabezon in spite of several efforts going back some 50 years efforts to introduce Atlantic salmon (whether with the direct release of smolts or the inadvertent release of net pen fish) to the region have failed. It is probably a good thing. Adding a fish like sea-run browns (and without a doubt their co-existing resident forms) would be at the expense of one or more of the native species. The fish they would most likely compete directly with (those with the similar life histories and habitat requirements) would be steelhead, bull trout and yes sea-run cutthroat.

I for one am thankful they are not here; I would not be willing to trade them for our steelhead, bulls and sea-runs.

I wasn't looking to take a pro or con stance, I was simply chillin' in my couch after a hard day at work reading up on flies for Sea-run Browns and wondered why we didn't have any here. We have many non-native species here that we're planted/introduced many years ago and it got me thinking if they were ever introduced and simply didn't make it or if it never really came up in someone's mind to bring searun browns to US waters.

I thoroughly enjoy the SRC action in the salt, I just wish they would be even more strict on SRC regulations. Maybe the average fish would grown even bigger if they did. The whole 14" is a keeper rule in the rivers is a bummer when I think about it.

Sorry i seem to have diverted from the OP. There are sea run browns on the West Coast, but like the OP noted, nothing I ever read about them being in WA. I don't think they are particularly abundant on the few west coast rivers they seem to exist.

What is really odd, is that one of the sea run populations that probably exists is just to the north of us in BC. It's interesting that they could gain a foothold there, but not in WA. I assume that browns were planted in WA coastal waters at some point.

Hi Alexander,
It is not a bad question. The literature on introduced species is full of cases where some species was repeatedly accidently or deliberately introduced to an area before it finally got established (including the devastating European rabbits to Australia). There is some hypotheses about what criteria are necessary for establishment, but they don't lend themself to experimental treatments very easily (let's release snow leopards in Olympia National Forest and see if they survive....).
Certainly, brown trout and Atlantic salmon have established self-sustaining runs in Chile and brown trout and rainbow trout in New Zealand (not sure if they are anadromous in NZ). They can make the jump from their natal waters to invade new habitats. It could be (pure speculation) that our native salmonids still maintain enough of a toe-hold to outcompete/outpredate the Atlantic interlopers.

Edit. Did a bit more research and one can add Argentina and the Falkland Islands to the range of searun brown trout and there are searun browns in NZ. The evidence for searun rainbows (i.e., steelhead) in New Zealand is a bit more problematic.

I don't know about sea runs, but there many places to get lake run browns in eastern Washington. They grow pretty big in some of the lakes. I know of some some runs that average well over six pounds.

Dmmitall! If we had searun browns here in Western Wa, then there would be no reason to travel elsewhere to find them. Moss would begin to grow on the north sides of our bodies. Not needing to leave this dismal soggy clime, we would all just stay here and mildew!
In fact, I fear that I am mildewing as I type this!

While I would like to chase sea trout (sea run browns) some day, I would not trade them for the NW locals. Not ever.

I know it is purely a personal choice, but I would take even a lowly "North Fork Firetruck" over any sea trout, if I had to pick one to catch the rest of my days.

But I am diseased.

I'm with ya, cuthtroat beach action is fun! I feel blessed with saltwater all around me, the cost of the sport I love can be managed a little better now that I don't have to drive far every time I want to fish, though the learning curve was steep. But SRC in the salt are fun, I do secretly wish they'd grow bigger though. ;). Like that monster searun trout in your link! :D

Alexander, I often use my 9' med/stiff action 4 wt for beach fishing, if the wind isn't up, and if the flies I'm using are small enough. The lighter rod allows for the sub-14" fish to feel like you have a good fish on the line, and feels much better matched to fighting searun cutthroat than my 6 wt, which often feels like overkill. However, my 6 wt is better for casting larger baitfish patterns, coneheads, etc, and casting in the wind.
But I prefer using my 4 wt, whenever I can. It does not overly stress out the fish if you use at least 3x tippet and know how to "put the wood" (use your butt section) to a larger fish.
I am now thinking that a med/stiff 5 wt would be about the right compromise for beach fishing for searun cutthroat.

Many Non native fish appear to have a difficult time persisting with native parasites such a Nanophyetus salmincola and their bacterial associates. Brook Trout, Brown Trout, and atlantic salmon seem to do OK only in areas above barriers or in areas without the intermediate host, a snail called Juga. Other examples probably exist. It is fortunate for us that our native fish have evolved to thrive in the presence of these organisms, and non native fish have not. Otherwise we would probably be more over run by exotics than we currently are.

Hi Alexander,
No, I haven't caught searun browns for sure. I have landed searun (and landlocked) Atlantics in Maine and Nova Scotia and browns and Atlantics in Patagonia (Torres del Paine National Park). I have caught both steelhead (in rivers) and browns (in lakes) in Washington. I can compare the fight of a lake-living brown trout and rainbow trout of similar length on the same day. The browns were more like bulldogs, lots of heart and power; they tended to stay deep until drawn up from the depths. Steelhead (or rainbows in lakes to provide a comparison in a similar environment) can give you that lightning run where your reel just sings. The steelhead seem to stay more near the surface. And they are happy to jump.

You can find in Steve Raymond's book, Steelhead Country, a great essay "In the Estuaries" in which he describes catching steelhead in an unnamed Puget Sound estuary in the late winter/spring. Trying to mimic that experience is on my list of adventures that I would like to try at some point.

There are a few populations of sea run browns on the eastern side of Vancouver island. They're pretty rare, though. I believe all of those rivers also have fairly healthy populations of resident browns present as well. Perhaps those browns that do go out to sea are just rare individuals in the resident population that got a genetic wild hair and decide to see what's down-stream rather than being individuals with inherited predispositions to anadromy. In any case, since they planted some of those streams from Scottish stocks well over 100 years ago, I have to believe that if those browns that went out to sea truly found a niche to exploit in the marine environment, we'd probably see a lot more of them.
