From the article:
$this->bbcode_second_pass_quote('', 'T')an noted that diesel fuel and petroleum-based lubricants easily eat up around 40 to 60 percent of the cost per trip of a 1,000-ton tuna purse seine fishing vessel.
At an average, a four-day tuna fishing expedition could use up about 10,000 to 15,000 liters of diesel fuel or equivalent to a maximum of P465,000, at P31 per liter, he said.

I wonder how many liters of diesel fuel that is to each 100 lb of tuna netted.
Food is Oil.

This may seem trivial to many, but again I think you really have to look about Peak Oil (and its effects) holistically.
By that, I mean, that you really have to look at water issues (erosion), food supply, and all of the other issues.
This is just one. If you consider that we may have energy troubles, than all other issues become much more difficult. I would suggest Jarod Diamond's book Collapse. He outlines the historically significant collapse of civilizations which disregarded holistic issues in their future.
We are depleting the food recourses of the seas. This isn't going to help the continuation of our species. We will have more trouble feeding the world population.
Abundant energy will help us transition from this wastefull enterprise. Declines in energy will only further the fall in food production.
Energy is important, but we have to look at it holistically. Great find mattduke!

Way past peak!
"It's been a slow-motion disaster," said Boris Worm, a professor at Canada's Dalhousie University, whose 2003 study that found that 90 percent of the top predator fish have vanished from the oceans."

New research reveals deep-sea fish population boom
$this->bbcode_second_pass_quote('', '.')..the scientists found a threefold increase in fish abundance, an upsurge that appears to have been driven by an increase in the food available to the animals. Bailey says the study is a unique glimpse into fish populations undisturbed by human influence.

Peak Fish occured several years ago.
It's down right depressing to see the condition of the world's fisheries.

I used to work at one of the best seafood restaurants in NYC. One customer would come in to eat 3 times a week or more every week that I was behind the bar including crudo, Italian style sashimi. His blood tested out 20 times the 'recommended' mercury levels, but he didn't stop coming to the restaurant though.

Mercury poisoning is nasty, and there's nothing at all you can do about it. I wouldn't risk it.

I have noticed recently a new 'fasion' of line caught fish in a local supermarket. Of course it is sold with the image of proper traditional fishing. It did occur to me at the time that if stocks are sufficiently depleted then line fishing becomes comercially viable and a better way to deplete the resource even further.
I thought later that I was being too synical but come to think of it again......possibly not.

Well done shadizar - best post that I have seen for ages!
The holistic effect of Peak Oil and/or the energy supply/demand gap is the KEY aspect of the situation.
I have commented on this in a couple of other posts: most people can see the problems in one or two areas ... BUT ... the current tendency towards "specialisition" means that many people no longer take the "helicopter view.
I strongly suspect that at some point we will hit a totally unexpected positive feedback loop which will give our society a severe knock. This will be caused by an unexpected chain of interactions between apparently unconnected industries.
The only way we can have any chance of preventing such problems is to computer model as much of the world's economy as we can.
I assume that such models already exists ... but I am having problems locating one!
(The Club Of Rome "Limits To Growth" model is probably too old and too limited to deal with the problem)

Thinking big picture, since I'll most likely be part of the forthcoming die-off worrying about cancer years down doesn't make much sense does it? If fish are going extinct, then so shall I with it!
