Length-based assessments revisited – why stock status and fishing mortality of long-lived species such as toothfish cannot be inferred from length-frequency data alone
with natural mortality, and knife-edge selectivity. But departure from the steady-state assumption ... which older fish accumulated. The removal of catch was modelled through three knife-edge fishing ... function is knife-edged, while the maturity function is not, Pmat includes some immature fish and is thus ...
