Skip to comments.Bigger Fish Due to Climate Change: Tuna Industry
Posted on 07/12/2008 6:10:17 PM PDT by Coffee200am
The tuna industry says climate change is bringing benefits.
The chief executive of the Australian Southern Bluefin Tuna Association, Brian Jeffriess, says Port Lincoln crews in South Australia are reporting an excellent quality and size catch.
He says it can be partly attributed to the effects of climate change on the waters of the Great Australian Bight.
"There's no doubt climate change will bring benefits to the Great Australian Bight ecology in the sense that there's more upwellings therefore more small pelagics as we call them - sardines, mackerel, red bait, other fish - and that will bring tuna so there may be even winners from climate change," he said.
"This year some of the oceanographers are saying they've never seen south-easterly winds in a sustained strong way now that creates a lot of upwellings in the water - that brings nutrients to the surface.
"There's a feed chain which feeds on those - the tuna is virtually the last part of that food chain and benefits from improvements in the other parts of the food chain."
hmmm, this could also explain the increase in Al Gore’s size...

I welcome our new Tuna Overlords...with mayonnaise, onions,pickles and celery...
I thought the Great Warming was being predicted, even though it's a bit colder this year, so how does this have an effect on fish now? Are they anticipating something?
Gosh! You mean to tell me that the biota has adapted to changes in solar output without man’s help? How can we tax that?
Humans as you warm the planet prepare now to bow to your future tuna overlords.
it has been a great year for Tuna.
It’s getting to where, no matter the effect, global warming is the cause.
Did someone say "Big Tuna"?
...this is a good thing right?
Actually it's Dianne Feinstein and her husband who are thrilled - they're getting rich off of tuna.
Cheaper tuna. Gotta love this propaganda called Global Warming.
It's good to hear they are more successful this year.
Global Warming hasn't made it to Table Rock Lake, MO & AR this year.
Biggest largemouth 5 lbs so far. Could it possibly be the skill of the fisherperson?
I spent my child hood boating out of San Pedro with my dad this was the late 60 s and 70 s loved to see all the fishing boats tones of them. now just a handful so sad
Toro! Toro! Toro!
My uncle operated out of San Diego until the late 40s but moved to Costa Rico and really cleaned up.
San Diego to South America and back was a long trip.
Short trips, through the Canal to Van Camps and when the Pacific quota was up fished the African coast and the canery trip was about the same distance.
And what climate change would that be??
I'm reminded of the baitman describing to his friends Homer Simpson-- the man who nearly reeled in the mythological fish, General Sherman:
" Seven feet tall he was, with arms like tree trunks. His eyes were like steel, cold, hard. Had a shock of hair, red like the fires of Hell."
Yuck. One of the funniest experiences I had going to the Rosalie Marie was when my co-worker stopped at the pilot house door. He put his index finger over his mouth and said "Sshh!". I was a bit perplexed until he pointed out the Dymo labeler label over the door. It read "No one aloud in the pilot house".
My saddest day with the fleet also involved the Rosalie Marie. I had finished checking all the PA mic stations before leaving the boat. That included the station in the shaft alley midway to the stern and between the fish wells. The shaft alley has the plumbing for all the anhydrous ammonia pipes used to cool the fish wells. Apparently the cook observed my truck headed back to the shop. In the time it took me to get to the office, the cook decided he needed to double check my work. When he got to the shaft alley station, an ammonia line blew. I heard the call for an ambulance on VHF channel 16 to go to the Rosalie Marie. It was later that day that I heard the cook was killed by the ammonia. It was a dangerous line of work. But for the grace of God, I might have been standing with the cook doing those checks.
