A recruitment-mortality model in the precautionary management toolkit of African tropical inland, single-species fisheries

► Composite (age-aggregated) metrics of stock status determination derived from a recruitment-mortality model. ► Approach aimed to complement existing methods used to index the status of African tropical inland fisheries. ► Approach illustrated with the Zambian Bukabuka (Lates stappersii) fishery of Lake Tanganyika, but can suit any single-species fishery.
