That's really cool! With any luck, they'll thrive and offer an amazing fishery.
I agree, looks like a new fishery.
So this projection is based on climate warming, and it is going 50 years in the future?
graphs are from Wisconsin Department of Natural Resources...This study.Quote:

Is this a good thing?
I think that the brown trout could be looked on as the invaders as the smallmouth are native to that part of the U.S while the Browns were imported from Europe. I have fished streams where they co-exist often and I believe a healthy stream can sustain good populations of both species.
Why worry? They are just a big sunfish anyway. While it may not be popular to say, smallies do taste good too!

I would agree that new smallmouth fisheries aren't necessarily a bad thing. The bad thing is that global warming doesn't end in 50 years. Instead it goes on and on until the climate stabilizes again, IF it ever does and who knows when and where that point is. Those new smallie streams could become catfish and carp habitat or just simply dry up and blow away if the climate becomes too hot and dry in that part of the world. I don't know if this will happen. It's just that humanity has never been down this path before and I think we should try to take the longest view we can.
So we are worried about an exotic species being partially displaced by a native species based on a 50 year forecast about a 3 degree temperature rise when we can't accurately predict tomorrow's temperature within 3 degrees?
Somewhere in all of this there is most likely a phrase that states-"our computer models show". That phrase always raises a red flag with me. The person or the group of people that are doing the study can make the "final" information show whatever they want it to show by tweaking their "computer model" .

As my Old Man used to say " Figures don't lie, but a good liar can figure". Not to say the guy is lying, but these thing can be manipulated.
BS. Humans were around at the end of the last "Ice Age" when nearly all the north american megafauna, and who knows what else, went extinct due in large part to CLIMATE CHANGE. Our species certainly has been down this path before, and we will be many more times in the future too.Quote:

Change is happening so fast now that time to adjust has been taken away and we need to try and slow things down.
The latest thing I heard is the arctic may be ice free in the summer by about the year 2020. I in all likelihood will live to see that day and that is when scientists expect climate change to experience a big bounce.
Why don't all of the folks that don't like CO2 in the atmosphere and global warming contribute to a solution and quit breathing both CO2 and hot air. The arctic has been ice free before and so has the antarctic. Before the beginning of the last ice age glacial period there were temperate forest as far north as 85 degrees north latitude. I think that points to a much warmer inter glacial period than the one we are in now. The earth gets warmer, the earth gets colder. I wish the so called climate scientist would make up their minds. Is it going to be an ice age as predicted in the 70s or a hot house and predicted on the 80s and 90s. The very notion that th climete change folks can use data from a very short 100 to 150 years, and that is being generous, and predict a cyclical system like the earth climate where the cycle is thousands and thousands of years is absurd. These guys are just full of themself and a major load of BS.
Let's hear it for the smallmouth bass and all of his warm water cousins.
I think I'll just build a sailing ship in downtown Miami, equip it with plenty of fishing equipment and wait for the ocean to come on it and float it. It might take awhile but as long as the Greenland and Antartic ice sheets keep on melting it will come and then I'll start trolling trying to figure out how far north those warm water ocean species have went.
Uuuh, let me check my "computer models" and I will get back to you. Maybe I can come up with one that will fit the agenda.

Never mind, the ice cap in Antarctica increased this year. If you would like I could loan you a sliderule, it's very green bamboo and uses no fossil fuel, unless you count the fossil who owns it.
Oh crap, the Antarctic ice cap grew this year! I'll have to depend on the Greenland ice sheet melting enough to float my sailing ship in downtown Miami.
I heard that the level of the ocean even went down 1/4 of an inch few years ago but then scientists found out Austrailia was hogging all the water in Lake Eyre. Since then the most if not all of the lake has evaporated and the ocean is back to creeping up. At least it was last time I heard.
You could just wait until the Cumbre Viejo (sp?) volcano in the Canary Islands decides to to finally slide off into the ocean. That landslide will trigger a "mega-tsunami" that, 6 hours later, will basically wipe the East Coast clean.
The sooner everyone wakes up to the fact that the climate change philosophy is all about politics, aaaarrrgggghhhh, lets just go fishing.!!!!!
Oh, the lack of faith in our elected officials and those who influence them; examine the word: Poli mean many; tic(k) . Any of numerous small bloodsucking parasitic arachnids of the family Ixodidae,. But I have an agenda also, the few smallmouth bass I have caught brought me more joy than any trout I have yet caught and they were their first. Hopefully, they can co-exist and both benefit.Quote:

The real problem for trout fishermen is going to be predation. Smallmouth are terrific predators and primarily eat other fish. A substantial smallmouth population can decimate other species. To reduce smallmouth predation on trout there would have to be sunfish, but bluegill are also great predators. So...it's a trade off.
I'm wondering if the crayfish population would increase or decrease as a trout stream warmed i.e. could the crayfish native to the trout stream adapt? If they increased I would think that would be good for the smallmouth. I'm also wondering if the cold water crayfish be displaced by a warmwater species. Questions, questions.
Don't sweat it. Enjoy the smallies. They will reach a balance at some point. We have both in my stream behind the house, and a lot more streams around here have smallies, brown, and rainbow trout.
I always assumed everyone had crawfish somewhere in their lakes and streams but the last time I was in the White Mountains of AZ I discovered they were considered to an invasive species there. There were plenty of trout to munch on them, I would have thought they would have added to the feedstock for the fish. I guess someone from LA needs to send them a video on how to catch and cook them, then they might be decimated and efforts begin to save them from extinction.Quote:

I did a google search, one article referred to them as Northern Crayfish, the other Louisiana red swamp crawfish. There's a potential growth industry, crawfish traps and Zatrains Crawfish Boil seasoning.Quote:

For the uninitiated, crawfish can be treated exactly like shrimp, and used as a substitute (better, in my opinion...) in any shrimp recipe. And, they are also killer catfish, SM bass, LG bass, and big bluegill live (or dead) bait.
Try putting some un-shelled crawfish tails on skewers, throw them on a grill or in the oven at 350 degrees, and baste them with some garlic butter, salt and pepper (go easy on the salt...crawfish are naturally a little bit saltier flavored than shrimp...). You'll never go back to Shrimp Scampi again. Another good use is to boil them (un-shelled tails, of course) until they just turn pinkish, throw them in a pot of Alfredo Sauce, simmer for 5 minutes, and serve over your favorite pasta (I use linguini most of the time).
I could write a whole cookbook just on crawfish (carp, too...).
