Invader asian crabs spread downeast

A volunteer working for a Canadian researcher Dave Delaney of McGill University just found a 22 mm female Asian shorecrab (Hemigrapsus sanguineus) on the north shore of Schoodic Peninsula, (presumably Gouldsboro.

This is unfortunate news. Now the ASC has colonized the southern (Isle au Haut) and northern extents of Acadia National Park. Even more alarming, the found organism was a gravid female with only a few eggs remaining.

This is the furthest north that the lobster-threatening invasive crab has been confirmed.

The staff of Acadia National Park, especially Jim McKenna and David Manski, have been assisting in the crab-watch.

This crab has had impacts in more southern Atlantic states. (massive population growth in the intertidal, crowding out other crustaceans.)

The strategy the Canadian resaerch calls for: start a trapping program throughout Acadia and the rest of Maine to control for the invader. The invader green crab now has an official trapping fishery with a commercial license. )

Hello fellow fisherman,

Did you know that 16% of the U.S. population goes fishing at least 16 days a year?

Did you also know that over 75% of the nations fishermen do not fish during "prime time"; fish feeding hours?

Those precious few moments before twilight can be absolutely magical. Even up until 11pm at night, the largest predators of any species feed ravenously.

Don't believe me? Check out Daniel Eggertsen's story, and a picture of a couple of his catches here : "Evening Secrets plus more"

I want you to do me a favor and try it out so I can see what you think of it, and if it works for you as well as it did for me.

You will be one of the first to try it out.

Gone Fishin',

Neil
