Data-Limited Population-Status Evaluation of Two Coastal Fishes in Southern Angola Using Recreational Catch Length-Frequency Data

Estimation of FNEPR rates based on the 4 parameter estimation approaches.
Results for dusky kob (A. coronus) and leerfish (L.amia) are presented in panels (a) and (b), respectively. Results assuming constant selectivity (μS and σS fixed over years) are presented in red (approaches ii and iv), whereas those assuming yearly selectivity parameters are in black (approaches i and iii). Dashed lines represent rates assuming the population is at equilibrium (approaches i and ii), whereas solid lines use the “n-fishing years” hypothesis (approaches iii and iv). The vertical dotted line represents an often-used limit reference point for medium to long-lived species established by Clark (2002).
