Using an Atlantis model of the southern Benguela to explore the response of ecosystem indicators for fisheries management

Climate, Anchovy, and Sardine

“…This type of model has shown that the Benguela Current System has undergone major reorganizations, particularly off Namibia from the 1960s (abundant sardine) to the 2000s (few sardine, increased gobies and jellyfish) (Shannon et al 2009). The Atlantis endto-end model has been applied to the southern Benguela Current System (Smith et al 2015). Similar models have been used to characterize the food web off southern Australia, which includes a major sardine stock, with particular attention to interactions between species, including seals and squid (Goldsworthy et al 2013).…”

Ecosystem modelling in the southern Benguela: comparisons of Atlantis, Ecopath with Ecosim, and OSMOSE under fishing scenarios

“…The models used in this study have been described in detail elsewhere, so we present here only a brief overview of each to highlight the differences and similarities in key assumptions and model structure. For a more thorough discussion of the Atlantis model used in this study see Smith et al (2015). The EwE model is described in Shannon et al (2003Shannon et al ( , 2008 and Travers et al (2010), and the OSMOSE model is described in .…”

“…Ecosystem function can be explored by tracking a suite of indicators under fishing pressure tests (e.g. Travers et al 2006;Smith et al 2015). Outputs of ecosystem models such as the Atlantis model in this paper can run to gigabytes or even terabytes of data, so some level of aggregation is necessary.…”

A continuous involvement of stakeholders promotes the ecosystem approach to fisheries in the 8-fjords area on the Swedish west coast

“…The EAF is applied on smaller scales in parts of Indonesia, the Philippines and Tanzania as well as on the Solomon Islands (Eriksson et al, 2016). Substantial progress towards an EAF has also been made in Antarctic waters (Watters et al, 2013), in the vicinity of the Benguela current outside southern Africa (Shannon et al, 2010;Smith et al, 2015) and in the northwest Atlantic (Link et al, 2011). Other similar initiatives are on-going in many parts of the world (Pitcher et al, 2009;Pomeroy et al, 2015; see also other articles in this journal issue).…”
