Natural mortality (M) is one of the most influential parameters in fisheries stock assessment
and management. It relates directly to stock productivity and reference points used for …

Limited data, and the requirement to provide science-based advice for exploited
populations, have led to the development of statistical methods that combine several …

The primary indices of abundance for many of the world's most valuable species (eg tunas)
and vulnerable species (eg sharks) are based on catch and effort data collected from …

Molecular genetic data have found widespread application in the identification of population
and conservation units for aquatic species. However, integration of genetic information into …

Marine biodiversity worldwide is under increasing threat, primarily as a result of over-
harvesting, pollution and climate change. Chondrichthyan fishes (sharks, rays and …

Population demography is based on simple models for constructing life tables from
reproductive and mortality parameters or on age-based models using Leslie matrices. Stock …

Investigations into population structure have been at the forefront of fisheries research for
decades, yet it is generally ignored in stock assessment models. As the complex nature of …

Integrated analysis (or integrated population modelling) methods have become the
preferred approach for conducting stock assessments, and providing the basis for …

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 …

We describe and illustrate a spatio-temporal modelling approach for analyzing age-or size-
specific catch-per-unit-effort (CPUE) data to develop indices of relative abundance and …
