Spatio‐temporal species distribution models can support fisheries assessments and management in marine and freshwater environments. However, the high costs of structured surveys often limit the spatio‐temporal coverage of the data available for modelling. To address this issue, we present a spatio‐temporal modelling approach integrating structured survey data with unstructured presence‐only data, which have greater spatio‐temp...

A robust assessment of the American eel ( Anguilla rostrata ) stock, required to guide conservation efforts, is challenged by the species’ vast range, high variability in demographic parameters and data inadequacies. Novel ideas and underutilised resources that may assist both analytic assessments and spatially oriented modelling include (1) species and environmental databases; (2) mining of data from scattered sources; (3) in...
