The rapid changes observed in many marine ecosystems that support fisheries pose a
challenge to stock assessment and management predicated on time-invariant productivity …

The productivity of many fish populations is influenced by the environment, but developing
environment-linked stock assessments remain challenging and current management of most …

Age-based stock assessments are sometimes rejected by review panels due to large
retrospective patterns. When this occurs, data-limited approaches are often used to set catch …

Maritime traffic and fishing activities have accelerated considerably over the last decade,
with a consequent impact on the environment and marine resources. Meanwhile, a growing …

The natural mortality rate (M) of a fish stock is typically highly influential on the outcome of
age-structured stock assessment models, but at the same time extremely difficult to estimate …

In addition to their role as a fisheries management tool, discard bans can be effective in
improving knowledge of total catches via the requirement to land and report all catches. This …

State-space models have received increasing attention in fisheries stock assessments given
their flexibility to incorporate multiple sources of process errors. Identifying which process …

Discarding can be an unknown source of biases and uncertainties in stock assessments.
Discarding patterns and quantities vary so a routine methodology for estimating discards is …

Two approaches to address retrospective patterns in stock assessments are compared. The
Rose approach is an ensemble of models that all remove the retrospective pattern through …

Stock status for many medium-and small-scale fisheries is unknown due, for example, to a
lack of catch data and the absence of scientific observer programs. However, length …
