Fishing
Definitions
Renewable Resource: resource that replaces itself unless badly mismanaged. For example, fish give birth to new fish and sustain a species' population provided that they are not fished at a faster rate than they can replenish their population.
Groundfish: fish, such as cod and sole, that live, feed, and are caught near the bottom of the sea. Pelagic Fish: fish, such as salmon and tuna, that live and feed in the open ocean. Shellfish: molluscs and crustaceans such as oysters, shrimps, and lobsters. Balance of Trade: difference between value of exports and value of imports. If exports exceed imports, there is a trade surplus. If imports exceed exports, there is a trade deficit. Continental Shelf: gently sloping outer edge of a continent that extends below the surface of the ocean to a maximum depth of about 200m. Banks: shallow areas of a continental shelf. Plankton: the name given to microscopic plants and animals eaten by small fish and shellfish. The small fish and shellfish are, in turn, eaten by larger fish. Inshore Fishery: commercial fishing that takes place within a few kilometers of the shoreline. Small fishing boats go out to sea and return to shore each day. Offshore Fishery: ocean fishery using boats longer than 25m. The boats stay at sea several days before returning to shore with their catch. Diversifying: increasing the variety Sustained Yield Management: use of a renewable resource at a rate that allows the resource to renew itself. For example, the number of fish caught should not be greater than the number of fish reaching maturity. |
