Incorporating technological interactions in a joint management procedure for South African sardine and anchovy

2016
Complex spatial structure and population richness are common in marine species and can provide regional stability in the context of localized environmental perturbation, ensuring long-term persistence. The most fisheries regulations are spatially uniform over broad-scale management units that reflect political, economic, and data collection convenience.

The acceptable level of risk for the South African sardine resource.

2019
An acceptable maximum level of risk for the South African sardine resource has been calculated by comparing the depletion of the effective west component spawner biomass from the recent Operating Model being used to develop OMP-18 with the total spawner biomass from previous Operating Models used to develop earlier OMPs. This results in a risk level of

A 2-stock hypothesis for South African sardine: two discrete stocks

2009
A 2-stock, 2-area hypothesis for the South African sardine resource is being developed, with the following boundaries: i) A “western” stock distributed throughout the “western area”, defined as the area west of Cape Agulhas ii) An “eastern” stock distributed throughout the “eastern area”, defined as the area east of Cape Agulhas As previously discussed
