Fish moving poleward at rate of 26 kilometers per decade
Large numbers of fish will disappear from the tropics by 2050, finds a new University of Britsh Columbia study that examined the impact of climate change on fish stocks. The study identified ocean hotspots for local fish extinction but also found that changing temperatures will drive more fish into the Arctic and Antarctic waters.
Using the same climate change scenarios as the Intergovernmental Panel on Climate Change, researchers projected a large-scale shift of marine fish and invertebrates. In the worst-case scenario, where the Earth’s oceans warm by three degrees Celsius by 2100, fish could move away from their current habitats at a rate of 26 kilometres per decade. Under the best-case scenario, where the Earth warms by one degree Celsius, fish would move 15 kilometres every decade. This is consistent with changes in the last few decades.
“The tropics will be the overall losers,” says William Cheung, associate professor at the UBC Fisheries Centre and co-author of this study, published today in ICES Journal of Marine Science. “This area has a high dependence on fish for food, diet and nutrition. We’ll see a loss of fish populations that are important to the fisheries and communities in these regions.”
Cheung and his colleague used modeling to predict how 802 commercially important species of fish and invertebrates react to warming water temperatures, other changing ocean properties, and new habitats opening up at the poles.
“As fish move to cooler waters, this generates new opportunities for fisheries in the Arctic,” says Miranda Jones, a UBC Nereus Fellow and lead author of this study. “On the other hand it means it could disrupt the species that live there now and increase competition for resources.”
This study follows previous research that looked at change in fisheries catch in relation to ocean warming since 1970.

Haaaa haaa.
FAIL. The models have not been inputed with how fish adapt, acclimatize etc. This is garbage of the worst kind.
I actually emailed him with a polite link to Dr Brown’s recent posting here and a suggestion that he not rely on models any more.
For how much longer do we the public have to be forced to keep on passing out our hard earned to keep these so called “scientists” and their bloody minded stupidity that is passed off as “science” and who in past times were otherwise known as soothsayers, witch doctors and shamans, in the life style to which they have become accustomed ?
Is it any wonder that respect for science and scientists is in free fall amongst the public when we see the “prophecies”, the “soothsaying” and the “scientific predictions”, such as the above very fishy claim, all the same thing in climate science and all based on nothing more than speculation arising from a whole descending and sequential cascade of unproven,unverified and unvalidated models, each totally dependent on the output of a similar level of unverified, unvalidated, unproven models not dissimilar to those Russian Matryoshka nesting dolls.
And from all of this al we ever get is non stop everlasting prophecies of glom, doom, death and destruction.
We NEVER ever see some output from some supposed scientifically based climate model and the interpretations by the so called climate scientists that suggests and proposes that we are looking at a much better and brighter future because of the changing climatic circumstances.
Economics was once labeled as the “dismal science”.
Economics has long been surpassed by Climate Science in the levels of it’s “dismalism” and has far exceeded economics by it’s self immolating and debauched wallowing in catastophism.
What a load of utter horses’ shyt.
The same happened during the warming 1917-1944. Lysgaard: Recent Climatic Fluctuations. 1949, and the tropics survived.
…Prof. William Cheung is travelling in Europe…
Good Lord! Modelling this leads me to believe that ALL our professors will be in Russia in a decade or so.
Best place for them…
That’s because all these professors know Russia is willing and able to prevent Obola pandemics within its border ….
“…Prof. William Cheung is travelling in Europe…”
Moving polewards at 26km per decade?
This is too silly for words. By my calculation, 26km is 16 miles which means that it will take the average fish roughly 100 years to move from NY to Boston.
I believe “Finding Nemo” was a more compelling fish story than the one Prof. William Cheung provides.

Hmmmn. Maybe this 26 kilometer “movement” will screw up the eel’s 2600 kilometer migration from Europe to the Sargasso sea off of Florida.
Then again, 26 kilometers might have been enough to prevent this Euro-eel from being eaten off the coast of Newfoundland.
The Benguela upwelling zone runs along the south west coast of Africa. Benguela is a province and city in Angola.
I wonder if they’ve ever heard of the changes in water temperature caused by ENSO?
By their theory the fish stocks in the central Pacific should be wiped out every few years. Or perhaps each species moves around following its preferred water temperature, rather faster than 26 kilometers per dacade.
From the Great Barrier Reef we have this from 2012.
Fish can acclimatize or swim. Why do they have to go extinct? We know some corals can shift northwards too.
I don’t want fish to go extinct.
(Brussel sprouts? OK by me!)
Sounds like a fish story to me.
Fish tale?
A whopper of a tale.
Pathetic. The PDO was discovered by a UW fisheries researcher who looked at historic salmon catches. The data showed that where the warm water was in an approximately 30 year cycle determined whether salmon were caught off the coast of the Pacific NW or Alaska.
The Team imagine that the climate never changed before 1977, apparently.
I’m soliciting for a series of re-analyzed model runs to show areas off Florida’s East coast to be warming up to 100°C or more. I need that data to apply for DoE backed “loans” for my startup “green” business to lessen our dependance on coal and oil. My solar powered fishing fleet will go to these newly modeled 100°C+ areas to catch “pre poached” fish thereby eliminating the need for evil fossil fuel energy to cook said fish later. “From Sea to Plate”© is our motto.
… It makes as much sense as their “study.”
Poppycock. Ocean temperatures vary much more than 3 degrees and pelagic fish follow the ideal temperature hundreds of miles yearly already. Take tuna for example….they travel the Pacific between Japan and the West coasts of the Americas constantly in well known migrating patterns. When tuna fishing the first thing you look for is water temp above 60 F. This is just another “insert AGW and get published and get your advertised.”
Nice word.
The migration has already begun.

Only till the poles switch 🙂
That’s not a fish so it doesn’t count. But it is sort of a pretty lil’ fella, that’ll capture the hearts of millions. So maybe it does count after all. My bad.
Wonder what it tastes like…
More fear mongering dressed up in sciencey clothes.
Somethings fishy…
“There must be some kind of way out of here, ”
Said the jellyfish to the reef,
“There’s too much confusion, I can’t get no relief.”
Let’s see; a healthy human body is said to operate at 98.6 degrees Fahrenheit. But that’s a misnomer. A healthy person can exhibit temperatures quite a bit more than one degree below and a bit more than one degree above that magic number. And, except for a few members of our species (that generally occupy the halls of government), we’re warm blooded. Last time I checked fish and invertebrates aren’t. (Ok, there’s a few exceptions with sharks and tunas.) So, a healthy warm blooded human animal can exhibit differences in body temperature of over 2%. But a cold blooded animal can’t for chrissake. In captivity tropical marine fish are advised to be kept at 78 degrees Fahrenheit water temperature. (I’m am American, I grew up with Fahrenheit although we didn’t know each other personally.) A one degree celsius change (I won’t bother with the 3 degree change since that’s simply ludicrous) represents a 1.8% change from that 78 degree American temperature. So, a warm blooded creature can handle a greater body temperature change than a cold blooded one which, faced with that itsy bitsy dilemma is gonna have to find some kind of way out of there. C’mon. Don’t for a second think there aren’t naturally occurring temperature gradients in the water already: warmer water washing back from the hot shores; cooler water flowing in from the open ocean; warmer water rising, evaporating and cooling. The water is in constant vigorous motion in the reefs. And then there’s the tide pools where the temperature changes, and also salinity changes, can be dramatic, and who’s creatures are very similar to their reef cousins. And, the constant churning of the reef waters insures oxygen levels are already above saturation, so any temperature change (which I’ll bet isn’t going to occur anyway) is unlikely to have impact on that. Moreover, isn’t it the cold, dry, polar air masses that are supposed to exhibit the most warming in these attack of the CAGW scenarios. Last time I checked the tropics are about as far away from the poles as you can get. Unless, of course, the Earth does some kind of cosmic, seventh dimension, internal, belly, double back flip.
Bollocks. Fish can swim a lot faster than that.
Something fishy about this study. Oh yeah! modeling.
Although northwards migration of fish socks northward gads been observed by fisheries:
http://www.nefsc.noaa.gov/press_release/2012/SciSpot/SS1209/
Awright. At the risk of having the crowd turn on me, I’ve got to fill you guys in .
In NE, the cod have taken a powder. The water in the Gulf of Maine has risen to temps that are driving them out. It started in 2010, and peaked last year. This has thrown fish management into a tail spin, and the enviros pof Pew, CLF are still harping about over fishing being the reason they are not there. Its complicated.
Last winter in the North East and Canada, the winter from Hell started changing things back. The Gulf of Maine was I little cooler this year. If we get the same kind of winter, it will be better for the fish. They will start to come back even more.
The cod collapse up in Canada is over because the Gulf of Maine cod migrated there. The scientists will dispute this fact. But an old fisherman in Newfoundland has said, he’s not seen fish like he’s seeing now in almost fifty years!
I can tell you right now, the fishermen from both countries know the score.
The scientists have not acknowledged this shift because of the computer models.
The two most important parts have been left out of the modeling, temperature, and predator/prey.
Those two omissions rob fishermen of the truth, and cause management to be flawed
This gives a good picture.
Mr. John Bullard, Dr. Bill Karp, Gene Martin, Esq., Gentlemen, I am addressing these comments to you and not the council because I believe you are the people that have to address the issue. From my perspective, as a scientist, NOAA committed two unpardonable sins with its press release on Gulf of Maine cod on August 1. Science was replaced with advocacy that day when statements were made about the condition of cod, and that immediate action must be taken after a secret, experimental stock status update before peer review http://fisherynation.com/letters
You answered your own question…..poor fish management is to blame.
I didn’t ask a question. I told you, (since you read it, I appreciate that) what has happened in New England and Newfoundland. This is not theory, its fact. If you choose to label setting catch limits using the best available science, (its not, but the government controls it, while Magnuson Stevens dictates it), with a fleet that has under fished bad management, I’d have to disagree.
The ones that would agree, the eco quackeroos of Pew, and CLF (the two Peters) cannot have it both ways. They are using climate as a reason to build off shore wind farms, close more bottom to fishing for “conservation” (causing localized depletion), and ignoring eco logical issues.
Also, while the cod take a powder, Black Sea Bass are moving in. Not good news for small lobster. They eat them like popcorn. Maine wants to start managing them. Setting catch limits! The next crisis will be lobster in the Gulf of Maine!
That link is a letter written by a fisherman that sat on the council for a nuber of years. Hes a very smart man. John Bullard is the Regional Admin of NMFS. Bill Karp is the head of the Northeast Science Center.
I stand corrected, you did not ask a question. Not understanding where stock might move is poor fish management. It happens. Saying AGW caused the fish to move is BS.
Well markl, I’m not a fan of this blog because I believe in the warming BS.
I’m also not saying this situation that I’ve brought up is a once in a lifetime, permanent event. There’s been boom and bust in the fisheries forever. These are natural events.
Facts is facts though, and its fact that this has occurred!
Chesapeake Blue Crab in Yarmouth Nova Scotia? Really!
Squid in the Gulf of Maine, usually found to the southward? Really.
Lots of kooky shit has happened. The premise that fish have moved towards the poles seems correct, however, is it permanent? I doubt it.
Already seeing changes because of last winters severity.
As far as your poor management dogma, You sound like a enviro quackeroo that believes the ocean is a fish tank in the living room.
Fish and Future
That fish is good for us is indisputable. Doubts today are planted as to whether fish will always be with us. Are not most commercial species of fish depleted? Yes, in part. But this answer does not look at the entire biomass. While some species are depleted, others are superabundant. Scary headlines insist that cod and other bottom fish are depleted; yet, mackerel and herring – the pelagics that live in the middle of the water column – are still superabundant.
It is only by looking at the entire biomass and the relationships among predators and preys that we might be able to find lasting and equitable solutions to the future physical utilization of the harbor. So far, we have identified one major predator-prey relationship: bottom fish and pelagics are in such a relationship. This is clearly visible as soon as one abandons the static, linear, pyramidal conception of the biomass. Predators are not always predators and preys are not always preys. At times predators become preys and vice versa.

I hear warmer water caused a glut of lobsters in recent years. Climate change is a funny old thing.
Something odd with cod.
It had a dramatic effect on lobster in the past few years. The warmer temps in the Gulf of Maine caused a massive shedding event. Two years worth of glut in the supply. Following last winter, which was colder ‘n a witches tit, these years lobster harvest was a lot more like it usually is.

As far as Cod go, they are having a cod renaissance in Canada, Some look at it as a crisis. Cod is cheap, they don’t have a market for it, following the dismantling of the industry in 1992, and they are scared to death that the cod will eat all the crab and shrimp they get top dollar for.
Pages of lobster articles here: http://fisherynation.com/?s=lobster
Canadian fishermen are very concerned that our refugees from the Gulf of Maine will eat the shrimp and crab stocks that they prefer to catch because of value, and not to mention the infrastructure to catch and process cod has vanished, while those same codfish are worth about .70 cents ex vessel price. Our bad boys are not welcome there, but, Nature prevails!
An earlier post, Does Newfoundland Fisherman Tony Doyle have the answer NOAA Doesn’t?
It’s a huge mystery to NOAA scientists. Where have the fish gone? The ENGO bunch seems happy to say that the New England fishing fleet has depleted the resource. Is that true, or have they done what the fishermen have said? They moved? Newfoundland Fisherman Tony Doyle says as far as ground fish go, he’s never seen anything like it in forty years of fishing! Listen to this audio, and key the broadcast to 13:40. His interview starts at 07:16 of the podcast. I enjoyed hearing his description!

I hope that none of these researchers suffers from malnutrition, and that they are generally OK.
Now all they need is a teary eyed fish sitting all alone in a vast ocean, as described by a teary eyed starlet begging us for money lest the little fishies die from starvation.
What is it about watermelons that makes them work so hard to get us to look away from real life solvable problems!?!?!?!?! Remember when we were drilling fresh water wells so that kids in Africa weren’t getting sick with Giardia? Whatever happened to that? Oh. That’s right. We must conserve water for the fish.
Idiots
Wouldn’t this change the angular momentum of the Earth?
No…. but it will change the angler momentum.
