Trophic models of the Benguela upwelling system : towards an ecosystem approach to fisheries management
… many upwelling areas. In the southern Benguela ecosystem, anchovy were dominant in the 1980s whereas sardine abundance increased in the 1990s. Mass-balanced models were constructed of the trophic flows in the southern Benguela ecosystem for 1980-1989 and 1990-1997 and in the northern Benguela …

Contextualising the bycatch 'problem' in the Olifants Estuary Small-Scale Gillnet Fishery using an Ecosystem Approach to Fisheries
Conventional fisheries management approaches have been shown, in many instances, to have been ineffective in dealing with complex conservation concerns such as bycatch. Greater considerations for broader-scale and holistic approaches, as proposed by the 'Ecosystem Approach to Fisheries' (EAF) and …

Assessing the effects of internal (trophic structure) and external (fishing and environment) forcing factors on fisheries off central Chile : basis for an ecosystem approach to management
… concern on the degraded state of fish stocks and ecosystems. Accordingly, fisheries science and management are expanding from the traditional single-species approach towards an ecosystem approach to fisheries. Marine communities are organized as webs of interactions that are affected by external …
