These parents must mature, spawn, and fertilize eggs which hatch to larvae, only a very small fraction of whIch eventually survive and become fully formed young fish (recruits). Generally the females of most fish species produce several thousands of eggs, sometimes even several millions as in the case of some commercially exploited species in temperate waters. To a certain extent tIus high fecundity has misled fishery biologists to assume that a very limited number of adult female~ would, in most fish stocks, be sufficient .to replenish the number of recruits that eventually become available to the fishery,.

متن کاملAn Evaluation of Harvest Control Rules for Data-Poor Fisheries
For federally managed fisheries in the USA, National Standard 1 requires that an acceptable biological catch be set for all fisheries and that this catch avoid overfishing. Achieving this goal for data-poor stocks, for which stock assessments are not possible, is particularly challenging. A number of harvest control rules have very recently been developed to set sustainable catches in data-poor...

The northern tuna stocks in the Pacific have specific characteristics: long-term large variability of the total biomass, sparse stock-recruitment relationship, and no obvious indication of recruitment overfishing even though the spawning stock biomass sometime fell into in a very low level. In contrast, southern stocks in the Pacific have one way decreasing trends in shorter exploitation histor...
