More than likely it's the definition of "conservation" that we disagree on. We can't climb up and down banks, drag boats over shoals or have wakes hitting the shores without doing harm to the environment. We have all at some time had a chunk of leader or line break off that will remain in the environment from several hundred years for nylon to forever fluorocarbon and spectra, and if you think about it there are a few other destructive things we do without remorse, like stepping on, killing, or kicking loose thousands of invertebrates when we wade. None of these things can be construed as any form of conservation. Sit on a bench in a trout park for an hour or two and watch how many line clippings fall to the ground and are never picked up, one for every knot or perhaps more? Stocking of non-native fish to give sports anglers variety at the risk of damaging or displacing native fish is not conservation. Transporting trophy fish miles from their homes and releasing them in a strange/hostile location for the sake of ego/money is not conservation. All "in my opinions" of course. And I do realize that some one else may say that extirpating bison and replacing them with Herefords is conservation in their view. Stocking of any hatchery raised fish has been shown to be detrimental to wild fish populations of the same species in studies, so are anti-conservation in nature, yet those stockings of sport fish are always done in the name of conservation.

Most of the electricity used in the E part of the hybrid is fossil fuel derived and there are energy loses at every stage of the conversion, transmission, transforming, rectifying, ect. Until we are producing all our electricity with nuclear, the Es are actually using more fossil fuel than not. The way to cause cars to use less fuel is to work near home or live near work. We need to redesign our cities to eliminate nearly all commuting. Perhaps make every high rise office building be 2/3 residential. With every block required to have a grocery and a hardware store. Or we can BS our way into extinction telling ourselves that the phase of cars will be powered by perpetual motion motors. No doubt that electricity is more efficient than diesel once you have made the electricity and moved it to the place of use. But the key is to track the energy and relate the total energy input to the end work. At my age it doesn't matter what you will have done to the earth in 50 years. But I see more negatives than positives in battery construction and use.

A species that hasn't reproduced in 80+ years must be considered to extinct, even if not all specimens have died yet. With no protections, unregulated killing, zero recruitment and the average angler's inability to identify them as not being 'carp'; the only reason we still see this species is because they live so long. It seems to me that sport fishing and conservation are at opposite ends of the spectrum. One can't truly be both.

That blood oxygen is the gas that fills the swim bladder, in one side from blood vessels and out the other side into blood vessels. A biologist could explain the complicated mechanisms involved.

Time factor, don't you think? like the fish that dart up at hit something at the surface, the air in the bladder takes a few moments to become affected by the pressure and temperature changes?

So I understand expanding swim bladders, but when we decompress too rapidly the gases in our blood makes bubbles that can cause serious harm or death, I wonder what happens to the fish's blood gases when they expand? and if they get bubbles like we do does that cause them to die later? Like, ya know, the air bladder might not be the worst problem the fish has.

Like we could remember all that 50-60 years later? I don't even recall the name of the girl who sat in front of me or the one behind me either. And doubt that Chemistry held more interest than Biology at that age.

The threshold would be both temperature and depth dependent, if the pressure change is enough to increase the bladder volume almost to the critical point, one or two degrees of temperature change put''s them over the line. Likewise if the temperature change is enough to bring the air expansion near the critical point a foot or three of depth could push it over. When you are catching several at the same water depth, and one out five shows distress while the others don't, it just indicates that all of them are probably nearly at that threshold. Of course there are probably other factors like individual fish may be more susceptible or one/some of the fish in the group may have just come up from a deeper position and not yet had time to stabilize at the depth that you caught it at.

No a hybrid relies on fuel, if the EV is to successful at eliminating the use of fossil fuels they must be self sustaining. A hybrid is just poor use of fossil fuels.

DC generators in the past were less efficient than alternators and if the generator is gas powered, the EV is not an EV it's gas powered. I had suggested 20 years ago that a Harbor Freight diesel generator in the trunk would expand the range of an EV. But, my intent in this post was that the alternator be powered by the electric motor that powers the car.

See, it took them twenty years to get one dam almost gone, and they think they'll get 30,000 of them at that rate? at 20 y/d that's 600,000 years even if they all worked out simultaneously 20 years is still a lot more than the 6 years they are talking.

They'll be fine if they stop wasting water washing cars and watering grass that they don't want and will cut down. The river will still be there without the dam. But wrench is probably right that this won't happen, they might take out the more controversial dams or the ones that are failing anyway, but I doubt they ever take them all down. As for electricity, they don't provide very much of our total needs. Put an alternator on those EVs and let them charge them selves.

You said you were good at Chemistry, the Ideal Gas Law was quoted above in algebraic form as "PV=nRT"; basic chemistry stuff. But we don't need the entire gas formulation to explain the bends; at -100' in water two things are different than at the surface, the pressure is higher and the temperature is lower. Boyles Law (ca 1662) states that "Volume is inversely proportional to Pressure" or that with a balloon full of air if the pressure is decreased (deep to shallow) the balloon will increase in size with no additional air. Charles' law (ca 1787) states that: "The volume of a given fixed mass of a dry gas is directly proportional to its absolute temperature at a constant pressure." meaning that a balloon full of air at 50F will increase in size if brought into 90F temperatures. The fish is not ingesting air as it is jerked up from the depths, but the air already in the bladder is expanding as the pressure decreases and the temperature increases. Think of the bladder as a sealed balloon that was filled to capacity at -100' pressure and temperature. No more molecules of air at the surface than at the depth, but the distance between the molecules has increased as pressure decreased and as temperature increased. I don't know about the fizzing healing fast or being a good ideal because if it didn't heal at all and the fish died when it returned to the -100' depth, the guy with the need would never know. As an experiment you can take a filled balloon, measure it's circumference, put it in the freezer over night, take it out and measure it again right away and it should by Charles' Law be smaller when cold. You can also take a filled balloon and squeeze it with your hands and see that the higher pressure from the squeezing makes the balloon smaller, but that it returns to full size when you release the pressure.

New tech doesn't change anything for me. I never watched TV fishing before and I won't now. Never been much of a spectator, but watching a fishing contest on TV is right up there with watching fresh paint on a picnic table. I can kinda understand the participation to win money, but it's a given that money will guarantee cheating, so I've never been that interested from that angle either. My take on all of it is that it is scam to sell boats and equipment. Every "free" boat or piece of equipment used by those guys and all the prize/bonus money awarded by manufacturers is paid not by the manufacturers but by the customers that get sucked into believing they need to have the same items to be successful. I'd say getting paid to follow the contestants around taking pictures/video of them is the best part of any tournament.

For trout walking I have a 50 year old aluminum net that I probably paid $3 for back then that really suits me better than any wood net I've seen or owned. It's outlived at least three bags and half dozen other nets. And it's still the lightest one to carry. It'd be no good in your boat though.

Wrench, on Tina's website she has a category "Build Your Own" https://www.customflyfishingnets.com/custom-wood-fly-fishing-net where you design and she builds it, but it looks to me like what you want might be $300+ with "4-6 WEEK TURN-A-ROUND" At the bottom of the page you can find a number to call and discuss the design and cost. You might ask if she has one hanging around that someone else ordered and didn't pay for or pick up or ...

Certainly don't hear much about those games, but out of curiosity I did a quick web search and was surprised at how many tough neighborhoods there are in the US, 140 hurling clubs in 50 cities. https://usgaa.org/about/ And you have one in your town @rps https://www.facebook.com/TulsaGAC/

Aren't those all to tough for Americans? Any high school or college leagues/conferences in those games?

Hard to believe the blast didn't exit through the muzzle if properly loaded. What caused the explosion?

Rigging plans? or finance plans? A web search indicates Boatwrx is some kind of nationwide company with locations in several states and possibly headquartered in Ca. per zoom, but I didn't try to track it all down and make connections, what is not clear is if just the Mo locations are restructuring or if it is in all states. It's not even clear if all the Boatwrx are connected or if the name is like Smith or Jones and each Boatwrx is independent of all others. But FWIW, post #28 seems to shed some light on the Mo locations. https://www.bbcboards.net/showthread.php?t=1239334&page=2

It's the short term financing that is the "floor plan"; used car dealers work their floor plan through banks or other lenders, in essence, every unit on the lot is specifically listed as collateral for that month's loan and is removed when sold. Supposedly using the money taken in the sale to reduce the loan. I don't suppose boat dealers need short term loans though, or maybe they do and call it something else. Yeah I get the idea of "rigging", I was sailor in my youth, USN and all that, before rigging it's just a hull. I just did not associate "rigging" with the "floor plan". As I said this place is an education.

Wasn't arguing with that, it's just that a "floor plan" is common way of financing cars on the "floor" at auto dealers, I've known a couple of car dealers, I've never known a boat dealer, so your use of the same term for something different surprises me.

Not what I would guessed was meant by "floor plan boats", I would have guessed it referred to boats on the dealer's premises but financed by the manufacturer. learn new stuff all the time. Now I know what a "prom queen" is too. This place is most educational.

National Parks are managed for tourism to promote the greatest number of visitors, with the most money spent, and have businesses inside them. I'd think that as a National River the area would have more of a preservation oriented management. If an investment group is behind the change, it is obvious that the change will open it up to exploitation. It's also probable that it is a done deal or the cat would still be secure in the sack.
