More about scallop
The scallop (Placopecten magellanicus) is found in the North Atlantic between Cape Hatteras and Labrador. It is found from just below tide level to depths of 100 m or more. Offshore commercial fisheries focus on banks found on the continental shelf which have depths less than 100 m.
Scallops are highly clumped (i.e. contagious) in their spatial distribution and occur most abundantly on gravel bottoms. Localized, dense aggregations are referred to as beds. Some beds occur sporadically while others are essentially permanent. More permanent beds appear to be in areas with suitable larval supply, temperature, current, food availability and substrate. Not all gravel bottoms support high densities of scallops.
More about the fishing methods
New Bedford scallop rake or dredge: The fishery is conducted by towing steel scallop dredge (locally known as the New Bedford rake) along the seabed. Each vessel typically employs two dredges, each varying in width from 15 -17 feet (~ 4.5 to 5.2 m).Towing speed ranges from 3 to 5.5 knots and tow duration commonly ranges from 20 to 30 minutes depending on conditions.
In 2008 the Total Allowable Catch (TAC) was set at 6,785 tonnes and landings were 6,725 tonnes.
Until 2002 the offshore fleet fished primarily for fresh scallops. Thereafter, with the introduction of freezer trawlers, IQF scallops began to be landed. In recent years these vessels have accounted for nearly 60% of the landings.
By value, scallop is the third ranked species (behind lobster and crab) in Nova Scotia with a worldwide export market in 2005/06 worth $121,510,883.
