The ecology and feeding habits of the American lobster (Homarus Americanus (Milne-Edwards, 1837)) in Newfoundland
The feeding habits, energy intake, and prey preferences of Homarus americanus were examined in the laboratory. Preference was determined by placing various animals in tanks with lobsters. This confirmed that sea urchins, crabs, mussels and periwinkles are readily eaten by lobsters. Feeding was obser...
