Abstract The South African coastline is just over 3000 km in length yet it covers three major
biogeographic regions, namely subtropical, warm temperate and cool temperate. In this …

Spatial stock assessments have been developed to address violations of the dynamic pool
assumption that the region to be assessed contains a single homogeneous stock. The …

Fishery management decisions are commonly guided by stock assessment models that
aggregate outputs across the spatial domain of the species. With refined understanding of …

The KwaZulu-Natal sardine run, popularly known as the “greatest shoal on Earth,” is a mass
migration of South African sardines from their temperate core range into the subtropical …

The waters off South Africa's coastline boast a rich mix of commercially fished species.
Quantitative assessments of these marine resources have developed from simple methods …

Misidentifying spatial population structure may result in harvest levels that are unable to
achieve management goals. We developed a spatially explicit simulation model to …

Fisheries are often accused of starving vulnerable seabirds, yet evidence for this claim is
scarce. Foraging energetics may provide efficient, short-term indicators of the fitness status …

Spatially stratified integrated population models (IPMs) can account for fine‐scale
demographic processes and support spatial management for complex, heterogeneous …

African penguins (Spheniscus demersus) in South Africa have been subject to rapid decline
in the 20th century and are currently listed as “endangered” on the IUCN Red List. A …

Differences in parasite infection have previously been used to distinguish between fish
stocks. We demonstrate a novel use of parasite prevalence-by-length data to inform …
