growth overfishing — the rate of fishing, as indicated by an equilibrium yield per recruit curve, greater than which the losses in weight from total mortality exceed the gain in weight due to growth. This point is defined as Fmax. It means that individual fish are… … Dictionary of ichthyology

growth overfishing — Occurs when too many small fish are being harvested, such that a restraint on their catch would lead to an overall increase in yield from the fishery … Fisheries — dictionary
Overfishing — Atlantic cod stocks were severely overfished in the 1970s and 1980s, leading to their abrupt collapse in 1992 Overfishing … Wikipedia
overfishing — 1) a level of fishing effort or fishing mortality such that a reduction of this level would, in the medium term, lead to an increase in the total catch. For long lived species, overfishing starts well before the stock becomes overfished. See also … Dictionary of ichthyology
overfishing — Current fishing levels may not be sustainable, and yields may be higher in the long term if the fishing level is reduced in the short term. This may be due either to growth overfishing or recruitment overfishing. Classification of a stock as… … Fisheries — dictionary
biological reference points — Indicators or signposts against which the status of a stock can be judged. Two types are often used: based on fishing mortality and based on the sustainability of recruitment. Reference points can be either desirable targets (target reference… … Fisheries — dictionary
biological reference point — a fishing mortality rate or biomass that may provide acceptable protection against growth overfishing and/or recruitment overfishing for a particular stock. It is usually calculated from equilibrium yield per recruit curves, spawning stock… … Dictionary of ichthyology
