A
fishery is an area with an associated
fish or
aquatic population which is harvested for its
commercial or
recreational value. Fisheries can be
wild or
farmed.
Population dynamics describes the ways in which a given population grows and shrinks over time, as controlled by birth, death, and migration. It is the basis for understanding changing fishery patterns and issues such as habitat destruction, predation and optimal harvesting rates. The population dynamics of fisheries is used by
fisheries scientists to determine
sustainable yields.
