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 biomass-per-recruit curves and stock recruitment data. Target reference points represent a desired level of fishing mortality or biomass while limit reference points represent either an upper boundary to the fishing mortality or a lower boundary of the biomass. Examples are F0.1, FMSY, Fmax and Fmed
