The target species is the green crab Carcinus maenas.
The green crab was introduced to the United States from Europe in 1817.
In large tanks, green crab conspecifics and the interspecific pair caused risk enhancement for prey.
The green crab arrived from the British Isles around the time of the American Civil War.
"Dad," Rolph asks, lifting a tiny green crab from a tide pool, "what do you think about Mindy?" "Mindy's great.
My study species is the European green crab, Carcinus maenas, a globally invasive temperate species that thrives across a wide range of environmental temperatures.
Therefore, mussels in southern New England had been exposed to both species of crab, but the mussels in northern Maine had encountered only the green crab.
And even if one developed a taste for, say, European green crab soup, there is nowhere to buy the main ingredient, though it is plentiful in the sea.
The two invasive predators, the green crab (Carcinus maenas) and the Asian shore crab (Hemigrapsus sanguineus), crush the shells of mussels before eating them.
The surveys confirmed an ongoing green crab spread into new productive oyster habitats while rapidly increasing in numbers in areas where crabs had established already.
But to my delight, back on shore, Mr. Astin confirmed it was a female European green crab, or Carcinus maenas (also nonnative and invasive), which he did want.
