unit stocks  

定义

  • Information A unit stock can be theoretically described as a group of individuals of the same species whose gains by immigration and whose losses by emigration, if any, are negligible in relation to the rates of growth and mortality. A unit stock is essentially a self-contained population with its own spawning area. It is isolated and fishing upon one unit stock has no effect upon the individuals of other stocks.
