PHAs: ‘Bacteria fat’ that can help us save the Chesapeake – Crab Pot’s, and Shotgun Wads

March 8, 2015 Marine Science

PHAs are plastics that are made by bacteria. PHAs also are eaten by bacteria. “It’s like fat,” Kirk Havens says. He explained that just as vertebrates store energy in fat deposits, many bacteria synthesize PHAs—short for polyhydroxalkanoates—to store carbon and energy. An individual bacterium will draw on its little dab of polymer reserve to get through the lean days in its microscopic world, unless a bigger microorganism eats it first. Anything made of PHA will biodegrade, simply because bacteria start eating it. Read the rest here 11:53

The New England groundfish debacle (Part III): who or what is at fault? Nils E. Stolpe/FishNet

It took me a while to decide how to most accurately describe the situation that has been visited upon the New England fishing communities that are and since colonial times have been dependent on the groundfish fisheries.

NILS STOLPE: The New England groundfish debacle (Part IV): Is cutting back harvest really the answer?

While it’s a fact that’s hardly ever acknowledged, the assumption in fisheries management is that if the population of a stock of fish isn’t at some arbitrary level, it’s because of too much fishing. Hence the term “overfished.” Hence the mandated knee jerk reaction of the fisheries managers to not enough fish; cut back on fishing. What of other factors? They don’t count. It’s all about fishing, because fishing is all that the managers can control; it’s their Maslow’s Hammer. When it comes to the oceans it seems as if it’s about all that the industry connected mega-foundations that support the anti-fishing ENGOs with hundreds of millions of dollars a year in “donations” are interested in controlling.
