Overfishing and human-induced climate change are putting severe pressure on marine
ecosystems. In the southern Benguela, most of South Africa's commercial fisheries have a …

Indices of abundance based on fishery catch-per-unit-effort (CPUE) are important
components of many stock assessments, particularly when fishery-independent surveys are …

Estimating trends in abundance from fishery catch rates is one of the oldest endeavors in
fisheries science. However, many jurisdictions do not analyze fishery catch rates due to …

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 …

Recreational fisheries can be prone to severe declines, yet these fisheries, particularly catch-
and-release, are often data-limited, constraining our ability to conduct stock assessments. A …

Age-structured production models (ASPMs) are often preferred over biomass aggregated
surplus production models (SPMs) as the former can track the propagation of cohorts and …

Polar cod (Boreogadus saida) and saffron cod (Eleginus gracilis) are key fishes in the Arctic
marine ecosystem, serving as important trophic links between plankton and apex predators …

Understanding the spatiotemporal behavior of fishermen at the fleet scale is key for defining
effective strategies for fisheries management. Here we classify the spatial patterns exhibited …

Standardized catch per unit effort (CPUE) is a fundamental component of fishery stock
assessment. In multispecies fisheries, catchability can differ depending on which species is …

Accounting for spatial and temporal variation in targeting is a concern in many catch per unit
effort (CPUE) standardization exercises. In this study we standardized southern bluefin tuna …
