Brief description

This dataset describes the relative abundance of an assemblage of commercially exploited demersal fishes in northwestern Australia, mapped over a 30 arc-minute (0.5 degree) spatial grid. The data cover the period 1997-2006 and are derived from an analysis of commercial landings available through the Sea Around Us Project (http://www.seaaroundus.org/). Further methodological details can be found in the following peer-reviewed publication, which applies the same analysis to a suite of mobile pelagic species: Bouchet PJ, Meeuwig JJ, Huang Z, Letessier TB, Nichol SL, Caley MJ, Watson RA. 2016. Continental-scale hotspots of pelagic fish abundance inferred from commercial catch records. Global Ecology and Biogeography.

Lineage

Raw data were filtered and spatially partitioned into 4 contiguous bioregions (North, Gascoyne, West, South), as per the management boundaries recognised by the Western Australian Department of Fisheries. Catch values were paired with estimates of fishing effort acquired independently and gap-filled (where appropriate) using a multivariate smoothing spline algorithm. Generalised linear models (GLMs) were used to standardise catch rates and account for the confounding effects of year, fishing gear type, body mass and effort. Model coefficients were extracted as relative abundance indices, and hotspots identified based on the position of the 45 degree tangents to their cumulative frequency distribution.
