Bait selection study of the invasive European green crab (Carcinus maenas) in Newfoundland, Canada
The European green crab (Carcinus maenas) is an ecosystem engineer, due to their advanced resiliency to environmental factors. They can tolerate a wide range of salinity and temperature, and have great dispersal capabilities. As true opportunistic scavengers and with low preference to a specific hab...
