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. Below is a full list of species/genera/families considered, with their respective contributions to the total catch (%): Mustelus -- 26.1948% Platycephalidae -- 23.3191% Seriolella -- 10.8968% Sillaginidae -- 9.4242% Genypterus blacodes -- 5.8347% Pristiophorus -- 4.4934% Tetraodontidae -- 4.3235% Nemadactylus -- 4.2784% Squatinidae -- 3.6071% Mugilidae -- 3.181% Sparidae -- 2.7037% Chelidonichthys kumu -- 0.7146% Rajiformes -- 0.4497% Pterygotrigla polyommata -- 0.3911% Scorpaenidae -- 0.1292% Callorhinchus milii -- 0.0367% Rhombosolea -- 0.0046% Pleuronectiformes -- 0.0034% Leiognathidae -- 0.003% Lates calcarifer -- 0.0029% Ariidae -- 0.0025% Sciaenidae -- 0.0017% Nemipteridae -- 0.0014% Nemipterus -- 0.0014% Upeneus -- 0.001% Data will be attached to this record once analyses are completed, est.
