Overfishing Responsible For Declining Fish Population (theguardian.com)

iONiUM send word of a new study into fishing practices around the world that found official reports have dramatically underestimated the number of fish caught over the past several decades. According to the Food and Agriculture Organization, global catches peaked at 86 million tons in 1996, and began a slow decline after that. This study suggests the peak was much higher — around 130 million tons — and subsequent catch rates are falling three times faster. Significantly, they believe the decline is not due to less fishing activity, but rather the exhaustion of supply in many areas. One of the study's authors, Daniel Pauly, said, "I expect a continued decline because I don’t expect countries to realise the need to rebuild stocks. I don’t see African countries, for example, rebuilding their stocks, or being allowed to by the foreign fleets that are working there, because the pressure to continue to fish is very strong. We know how to fix this problem but whether we do it or not depends on conditions that are difficult."

      It is unfair to blame the Guardian for a stupid Slashdot headline. The point of the study was not to show that overfishing caused fish stocks to decline (we already knew that), but to actually quantify the rate of decline. The Guardian's headline expresses that accurately, while the Slashdot headline is misleading.

      Well, what you do in order to feed those billions makes a difference, doesn't it? Even if you feed them wild fish, how you harvest those fish makes a difference. Unlike, say, manufacturing widgets, unregulated extraction doesn't maximize output over the long term. Fishing isn't production, it's extraction, and since it's a renewable resource you want to extract in a manner which doesn't shift the system equilibrium -- you don't want to live on your environmental capital.

      I once saw a presentation by a marine ecologist who modeled the impact of marine sanctuaries, and his model showed that long term fish catches were maximized by creating large marine sanctuaries and intensively fishing around the sactuaries' perimeters. Now this is just an idea, mind you, and a compelling argument isn't the same as proof; but this is the kind of idea we need to consider. You could say, "Screw it, we've got seven billion mouths to feed," and catch as much fish as you can in the short term, but that only makes your problem worse in the long term as you extract each fishery down to the point of collapse.

      I thought the sanctuary idea was interesting because it would be way simpler to enforce than giving each fishing boat a quota. All you have to do is ensure fishing boats don't go into any no-go areas. Rather than trying to divvy up a total catch fairly, you simply maximize the system output and let market forces determine who stays in business; meanwhile you maintain completely pristine and maximally productive areas, extracting only the sustainable surplus they produce rather than eating your metaphorical seed corn.

      Yeah, it's a big problem, but you only make it bigger by throwing up your hands in despair.

      Fisheries are not a linear system where any negative pressure automatically results in a population decrease. Contrary to the adage, a "delicate balance" in nature is extraordinarily rare, almost unheard of. Any delicate balance by its very nature ceases to exist pretty quickly.

      Most systems in nature are extremely stable, able to absorb huge variances in input forces without destabilizing. Anything less stable already self-destructed millions of years ago. Fish populations can absorb a substantial amount of predation while still being self-sustaining. But eventually you hit the limits of the system's ability to self-stabilize and the population begins decreasing. Simply fishing does not automatically lead to depletion; fishing beyond this point of sustainability does.

    Yeah, let's get larger and larger factory ships which are capable of staying at sea longer and process the catch directly. Let's also implement massive drag nets that also destroy the sea bed, coral and any other habitable environment for fish nurseries and you'll have massive extinction areas which are already forming. Great job progress! Winning!

    We know how to fix this problem.

    The implication is that we should dial back fishing in order to let the stocks replenish.

    Which means, hypothetically, you need to take all the fishing boat owners in, say, Boston Harbor and say "30% of you have to stop fishing".

    And with no plan for what to do with the out-of-work owners and their families and some deck hands and their families. Just "stop fishing", that's how to fix the problem.

      Ah yes, the old assumption that doing nothing is somehow a sensible default option.

      Thing is if you don't force 30% of those boats out of work, then the fish stock will collapse and force 100% of the boats out of work. And those who object to putting 30% out of work sure as hell have NO plan with what to do with the owners, deckhands and families when they're all out of work.

      So yes, "just stop" is in fact a better plan than carrying on.

    Studying overfishing is done by scientists, not fishermen. That should cover the STEM part. With better data on overfishing, we can make better policies, based on science, to try to reverse the problem. It was technological advances (sonar, etc) that allowed the cod fishery in eastern canadian waters to be overfished to the point that it collapsed.

    Not only is going vegan stupid from a physiological standpoint (the fact is, our brains couldn't have evolved the way they did without meat; the fact that we could get away with eating vegetables came later after we selectively bred them to have a high enough energy density, and no vegan anywhere ever could survive off of truly wild plants) but some people have dietary needs that just can't work on a vegan diet.

    There are wild plants that supply most nutritional requirements. Take wild hemp seed, has all the vital amino acids, all the essential oils, as well as most B vitamins. For energy density there are various wild roots as well as nuts that pack a lot of energy and many wild greens are much higher in vitamins and minerals then cultivated greens. Cultivated plants such as head lettuce are mostly water with generations of selective breeding for looks rather then nutrition. Even tomatoes have suffered from the selective breeding to make them good lookers and shippers rather then tasty and nutritious.
