The maximum amount of fish over a period of time (year, season) that can be produced by a fishing fleet if fully utilized while satisfying fishery management objectives designed to ensure sustainable fisheries: YT = Y (ET, S) in which YT is target yield or catch; ET is target effort generated by a fully-utilized fleet; and S is stock size (biomass). The "fishing fleet" is meant to be the stock of inputs (i.e. physical capital and human capital). The term "fully-utilized" is used in a precautionary context in that it is assumed that capacity utilization is 100%. The maximum catch that capital stocks could remove can be determined by observing the fishery under study during a period with few restrictions.
Industry:Fishing
Part of the continental margin; the ocean floor from the continental shelf to the continental rise or oceanic trench. Usually to a depth of about 200 meters. The continental slope typically has a relatively steep grade from 3 to 6 degrees.
Industry:Fishing
Fishing mortality rate corresponding to an equilibrium spawning potential ratio equal to the inverse of the survival ratio at the origin of the stock-recruitment relationship. A stock fished at or above this level for a prolonged period of time is expected to collapse.
Industry:Fishing
Species of relatively small (usually pelagic) fish that congregate in large schools, such as anchoveta and sardines.
Industry:Fishing
Fishery where the number of operators (and size of boats) is restricted through license limitation or quota systems, to control the amount of fishing effort. It frequently involves controls on the number and size of vessels, and conditions relating to the transfer of fishing rights or the replacement of vessels.
Industry:Fishing
The pelagic environment between depths of 1,000 meters and 4,000 meters.
Industry:Fishing
Longlines consist of a main line, sometimes of considerable length, to which snoods with baited or unbaited hooks are fixed at regular intervals. The main line is set either horizontally on or near the bottom or less commonly near the surface.
Industry:Fishing
Large, relatively flat shoal or other expansive submerged feature that is markedly shallower than the surrounding ocean bottom (e.g. Georges Bank with water depths between 30 to 50 meters).
Industry:Fishing
The pelagic environment from a depth of approximately 4,000 meters to 7,000 meters.
Industry:Fishing
The number of individuals known, estimated, or inferred to be capable of reproduction.
