In Canada, all crustacean species with significant economic value are in the order Decapoda. The decapods constitute a major portion of the dollar value of various Canadian fisheries, and in some areas, particularly in the East, the local economy is almost completely dependent on them. The American lobster (Homarus americanus) is the most valuable of these resources. Freshly caught lobster may be shipped live immediately to points in N America, Europe and Asia, or held in pounds until demand and price are more favourable. A much smaller percentage is cooked and canned.
Some areas in the Gulf of St Lawrence have special fisheries for "canner" lobsters, which are slightly smaller than the "market" sizes shipped live.
