Fishing Fleets Overexploiting Seas at High Rate, Study Warns
Highly mobile fishing fleets are exploiting the sea’s resources at an unsustainable rate, according to a new paper published Friday by more than a dozen international researchers in the journal Science.
The paper, which looks at how “roving bandits” swoop in and plunder fisheries at a rapid rate, looks at how some fish populations have collapsed within a matter of years. In Maine, the sea urchin became a popular commodity in Japanese sushi markets in the mid-1980s: After peaking in 1993, the catches declined precipitously….
Peak oil, peak seafood (no disrespect to ocean life forms that don’t think of themselves simply as food, regardless of how delicious they are). Speaking of which, I was very disappointed to see Thai shrimp in the Hanover Co-op yesterday: almost guaranteed to be “farm” shrimp which is bad, bad, bad. Shrimp farms tend to be established through the clearing of mangrove forest. These forests are pretty vital system, protecting shorelines, providing breeding habitat for numerous species, providing living resources for traditional peoples, etc. But they get plowed cuz none of those things count for cash dollars like shrimp. And then, usually, the shrimp farms silt up and shut down after only a few years — so the farmers move on to the next patch of mangrove. Uncool.
