This point is called the maximum sustainable yield, and in practice, usually occurs when the fishery has been fished down to about 30% of the biomass it had before harvesting started.
Este punto denomínase rendemento sustentable máximo, e na práctica, xeralmente ocorre cando se pescou no caladoiro ata quedar só o 30% da biomasa que tiña antes de que empezase a pesca.
