AAP Project 4501: Mapping, predicting and monitoring ecological change in the Southern Ocean - HIMI Demersal Fish

The demersal fish assemblages on the Kerguelen Plateau has changed through time. This study aimed to detect, quantify, and map these changes. This study uses existing data collected from the Random Stratified Trawl Survey (RSTS) program administered through the Australian Antarctic Divisions (AAD). Raw RSTS data between 2000 and 2016 was extracted from the AAD database. The RSTS data contains information on the abundance (catch per unit effort, CPUE) on fish. RSTS data were paired with environmental data to be modelled. Hierarchical models of species communities (HMSC) were used to make inferences and predictions in the changes of demersal fish distribution. This record contains all the environmental data, R code, and outputs from this project. Raw RSTS data needs to be requested from the AAD under the authorization of AFMA.

Statement
Hierarchical Modelling of Species Communities (Hmsc), a flexible framework for Joint Species Distribution Modelling (JSDMs), was used to analyse catch per unit effort (CPUE) data collected from the Heard Island and McDonald Island (HIMI) Random Stratified Trawl Survey (RSTS) program. For more information on the methodology behind the RSTS please refer to associated publication. RSTS data is subject to confidentiality agreements and can be requested through the website (https://data.aad.gov.au/metadata/records/HIMI_RSTS_Strata). Rasters of the environmental data relevant to demersal fish analysis were sourced from various databases and data products and matched with the RSTS data locations For further information on the data and rasters used please refer to the publication. All environmental data used in the modelling are freely available and supplied R code outlines how the data were wrangled and used in the modelling process Annotated R code is provided to: 1) RSTS data wrangling 2) Environmental data wrangling 3) Hmsc modelling and evaluation 4) Plotting 5) Predicting and mapping Outputs, including predictive maps, from the Hmsc model are also publicly available.
