Sustainability: Don’t waste seafood waste

August 10, 2015 Marine Science

Every year, some 6 million to 8 million tonnes of waste crab, shrimp and lobster shells are produced globally — about 1.5 million tonnes in southeast Asia alone¹. Whereas 75% of the weight of a tuna fish can be extracted as fillets, meat accounts for only around 40% of a crab’s mass. Yet shells harbour useful chemicals —protein, calcium carbonate and chitin, a polymer similar to cellulose, but which contains nitrogen (see ‘Shell biorefinery’). The potential value of such shells for the chemical industry is being ignored. Read the rest here 21:16

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.
