No profits found in this tangled catch – Fishermen taking a beating!
Local fishermen this year have had a tough time with a species of red seaweed, an algae, that looks like matted hair. The algae began to bloom and spread in May. Nets would get fouled – often beyond recognition – and the fishermen would spend hours cleaning them, only to have their nets get “weeded up” on the very next tide. And to add insult to injury, when the weed was thickest, covering acres of the seabed, the nets would often be empty of fish. Read the rest here 13:23

Portland Press: Our View: Public-private partnership critical to kicking green crab out of Maine
Given how high the stakes are for the state’s marine habitat and its third-largest commercial fishery, Maine has to focus on removing green crabs from coastal waters as quickly as possible. As state marine ecology researcher Brian Beal told the Press Herald in February: “How do you get rid of an invasive species? You fish ‘em to death. We did an awful good job of reducing the population of sea urchins without even trying.” Read more here 10:17

Can US eliminate invasive species by eating them?
HOUSTON (AP) – It seems like a simple proposition: American lakes, rivers and offshore waters are filling up with destructive fish and crustaceans originally from other parts of the world, many of them potential sources of food.

The Great Sea Urchin Crisis – “They’re completely dying off,”
Tye Zinck chips the ice off his scuba mask, yells a warrior cry and lunges off the boat. Until he can slow his gasping, he floats atop the 40 degree water, the wind of Sambro Cove, Nove Scotia, biting at his ears. The seams of his dry suit are so thick that it looks inside out. Read more here 11:56

And some fear lobsters will be next. European green crabs are devouring a shellfish buffet along Maine’s seashore, plundering populations in their wake. To get a snapshot of just how severe the problem is, clammers, scientists, and marine officials took a survey today along Maine’s coast.

Snakeheads break out of Potomac, enter Rappahannock River
Richmond Times-Dispatch – The northern snakehead, an invasive species of fish native to Asia, has successfully broken out of the Potomac River system and established itself in the Rappahannock River, according to state officials. The fish drew headlines when it turned up in a Maryland pond in 2002, in part because of its prodigious teeth and ability to survive several days out of water by breathing air. Spotted less than a decade ago in the Potomac, the snakehead has not just survived, but spread. continued
