Climate Change Drives Fish Into New Waters, Remaking an Industry (wsj.com)
The catch is shifting northward as water temperatures rise, forcing crews to retool their boats and rework their businesses. From a report: Aboard the Stanley K and the Oracle, two 58-foot vessels, Buck Laukitis and his crews chase halibut across the Bering Sea worth $5 a pound at the docks. As sea temperatures rise, and Arctic ice retreats the fish appear to be avoiding warming waters, migrating northward where they cost more to reach, federal fisheries biologists say. Twice this past fall, the Oracle sailed 800 miles north from the seaport of Dutch Harbor in the Aleutian Islands, before finding the halibut that a decade ago lived several hundred miles closer to home. Each voyage took twice as long and yielded half as many fish. "It keeps me up at night," he says. "I woke up at three in the morning. I couldn't sleep thinking about where the fish are going."
Across the continent from Mr. Laukitis in Rhode Island, black sea bass have moved in with the warming waters. The bulk once lived roughly 700 miles south off North Carolina. Now they are a staple catch in Point Judith, R.I., along with the summer flounder that also have begun appearing. [...] The impact of climate change has a price, and for fishing-boat owners in sea ports, that means following the catch. The northward movement of fish around the world is disrupting some fishing grounds and revitalizing others -- and fishing businesses are trying to adapt their operations.
The impact of temperature on oceans is varied. As the atmosphere warmed in recent decades, oceans absorbed heat unevenly, causing marine hot spots that can last months, scientists say. Spikes of warmer water affect fisheries differently depending on ocean currents, ocean depth and seafloor topography. Higher temperatures mean less dissolved oxygen in the water while increasing a fish's demand for oxygen by speeding up its metabolism. Warming water may also favor predators or drive off species on which commercial fish feed. All told, warming ocean temperatures are pushing hundreds of marine species outside of their traditional ranges, ocean scientists say.

The oceans are massive and vast and deep beyond comprehension. There is absolutley nothing humans can do to change its temperature. What cookie cutter group think to believe that we humans can warm the ocean. But y'all get a red star on you forehead from the commissar of propaganda for being good little young pioneers.

Sometime change costs some people money (and risk), and sometimes the exact same change reduces peoples' costs (and risks). Imagine that. The human mind is capable of reasoning about and understanding patterns that will allow us to adjust to changes in our environment. Perhaps we're not all going to die (at least all at once).
If humans are mostly water, and beer is mostly water, then humans must be mostly beer.
Over fishing is a huge problem, bigger so than climate change. Its something for the UN to sink their teeth into where they can really make a difference.
with the lobster industry. One of the frustrating (or amusing if I'm feeling mean) things is watching several "red" states (e.g. they vote GOP, the party currently calling Climate Change a hoax) clearly impacted. Florida had a huge problem with red tide this year. If it keeps getting worse it'll kill their tourist industry. Meanwhile the SEC filings, where mega corps aren't allowed to lie, are chock full of lines about the negative impacts of climate change.
I'm not necessarily blaming the rank and file though. Most of the Dems don't really have a solution besides "consume less", which would be great if a) the vast majority of pollution was from consumers and not the companies they buy from and b) folks weren't living paycheck to paycheck so on edge they're terrified of any change. A few lefties like Bernie Sanders and Alexandria Ocasio-Cortez have suggested a "Green New Deal" to address this, but the Clinton Democrats (the right wing of the party) don't want to tax their wealthy donors to pay for it all.
So the result is this, we're all going to hell in a handbasket and just pretending it's not happening.

could this be it? never a better time/reason to consider ourselves in relation to one another, our surroundings, & our endless creative spirit? cease fire stand down.. in the moms (our earth bound creators) we trust.. the give away more than we keep light is still on.. better days ahead for sure.. see you there
next; does greed & fear based hoarding shorten our lives? plus, the ups & downs of oathing ourselves/others...
The restaurants now can buy local black sea bass instead of having it cooled and sent by truck for 700 miles which is good for the climate.
Maybe the fish are moving north because fish stocks around the world have been fished to the edge of collapse and the only place a species can survive now is expensively far from the reach of man.
But that would be proof that we're just greedy fucks. Unlike climate change where we can blame everyone else.
I'm glad this keeps Buck Laukitis up at night. It should.
If people consumed less, the companies would produce less...
It's not rocket surgery
And the federal government is shut down. Good news all around!
In this case, the fish are moving not because of water temperature, but because of decades of overfishing.
Halibut are perfectly capable of thriving far south of the Aleutians but have migrated north because they are still relatively unmolested there.
Don't let the climate wackos dupe you on this one.
Florida's elections are staggeringly corrupt and pretty close. There's also a mounting of disenfranchisement. 1.5 million Floridians can't vote because of a criminal conviction. They've restored virtually noone's voting rights either. A law was passed to give 1 million of them their rights back and their corrupt legislature is blocking it. And that's just one example. There's a ton of evidence of votes not being counted, voting machines not working in left leaning districts, etc, etc.
The FL GOP is as crooked as a dog's leg. If the national media was doing it's damn job they'd all be in prison.

that's where climate change comes in. Red Tide due to phosphorus is a problem, but it's exacerbated by warming due to climate change. All sorts of things we used to get away with become untenable once climate change is factored in.

"The northward movement of fish around the world"
Uhh no that would only apply to the Northern hemisphere.
Anyone who bothers responding to you is dumber for doing so, go die in a fire you treasonous inbred troll.
I love me some fresh fish!
And why is Al Gore buying beachfront land in CA?
Why doesn't the left do anything except jack up taxes?
Is it a profit scheme?
Yeah well, the fish heading south are going to bump into a huge land mass before they get near the pole.

Here in Alaska, there is always concern over the fish stocks. The commercial boats want to catch as much as possible for as cheaply as possible. The sport fishers and charter boats want to catch a reasonable amount (relatively small) and have fun doing it. And the subsistence fishers just want to pack their freezers so they can survive.
From my sport fisher point-of-view, aside from the climate change bits, the problem is over-fishing by the commercial boats. Those trawlers just catch sooo many fish. 8y ago, our average halibut was 45-50 lbs, and keep 2 of any size. Now its
The salmon aren't any different. The return numbers and escapements continue to get lower. And I can't tell you the last time the US met its TREATY goals with Canada. If the commercial boats catch all the salmon in the ocean, they can't return to spawn to make more fish.
Many of these problems are man-made with straightforward solutions.
"The quality of life is determined by its activites."--Aristotle
Yea not, just another lib hippy link that may or may not be actually related to there favorite dead horse flogging.
Now that fishermen are netting fried cod and grilled halibut, the boats are being redesigned to keep the catch piping hot from net to dock.
Chances are good that Sardines will migrate north and restart the sardine cannery in CA. Sounds like it is minor, but at this time, the Sardines are around mexico and China basically raids the fisheries quite frequently
I prefer the "u" in honour as it seems to be missing these days.
Let's say you are correct in all aspects. This still puts the Democrats in a far superior position, in every respect.
In order to solve a problem, you have to acknowledge the problem first. The Republicans deny there even is a problem, they are still stuck with their head in the sand. For them to change course on Climate Change is a much more difficult challenge.
The Dems merely have to say, "well, now it's time to enact some policies, and maybe it's going to cost some money".
Twice as bad as EU and China, but still you get worse. When is enough?
Tides are affected by the moon.is Global Warming now changing the moons orbit too?
Back to science classes for you...
Currents and oscillation are not controlled by the moon. When you finish 8th grade, you can then move on
WindBourne's post (to which the AC you were responding to was himself responding to) said, "there is fast tidal movement..." The AC you're responding to is quite right: tides are caused by the gravitational attraction of the moon and (to a lesser extent) the sun. They are also affected by other things, such as the size of the water basin (tides in the Atlantic can be sizeable, while tides in the Great Lakes are negligible), the position of the measuring station (tides act something like standing waves, so the tidal range tends to be greatest on the margins, and least in the middle), other geological factors (tides in the Bay of Fundy can reach 50 feet or more, due to the shape and length of the Bay), and yes, to some extent by weather. But to repeat, the ultimate cause of tides is the gravitational attraction of the moon and sun.
Perhaps you should repeat eight grade. Oh, and on a lighter note, you might read Larry Niven's "Neutron Star", and pay special attention to the ending.
Currents aren't tides though are they...
Back to kindy for you? Or just buy a dictionary without pictures?
How do you propose to do that?
You can't even stop importing useless junk from China that you don't even need. A billion dollars a day, your tariffs only made it go up!
Horseshit. Fishing pressure is what is driving the migrations, we are seeing the same thing with salmon returns in the puget sound. Returns are pushing later in response to commercial netting, which tends to be front loaded in the run.
And it's not fish running away from nets or longlines; it's the stocks in impacted areas being fished out, such that you only find fish in more remote areas or later in the season.
