The young are brought back into the area by the Gulf Stream. Juveniles live in the Gulf Stream frontal zone and slope water off the edge of the continental shelf until they reach about 10 cm in length. Significant quantities of lobster occur at the shelf edge from Browns Bank to Sable Island Bank. One of the two best-known areas of concentration of the Northern Bottlenose Whale is in The Gully. Sperm Whales are usually found along the edge of the continental shelf or over canyons and deep basins between banks.
Seabird concentrations are greater in the shelf edge owing to the elevated productivity there.
Wintering dovekies are most common over the edges of the Scotian Shelf. On Georges Bank, Wilson's Storm-petrel is most common over the shelf break. Cultural Environment Like Unit 931, the major marine activities on the shelf edge are fishing and oil and gas exploration. Harvestable concentrations of deep-sea Red Crab occur along the Scotian Shelf edge from the Fundian Channel to Sable Island. In the 1960s, whalers out of Blandford caught 67 Northern Bottlenose Whales.
