A hands-on discussion and tutorial for using FishStats to estimate spatio-temporal abundance indices, distribution shifts, and range expansion in 2017 stock assessments
Collaborators and I have been developing, testing, and documenting spatio-temporal models and software for single- and multi-species analysis of fishery and/or survey data. R packages for implementing these models are now publicly available and documented through www.FishStats.org, a spatio-temporal toolbox for fisheries science.
In this Think Tank, I will present a small number of slides (<15 total) to recap recent model developments and applications. I will then lead a discussion of different applications for which FishStats could be useful in 2017 stock assessments, e.g., estimating survey indices, standardizing fishery catch rates, estimating distribution shifts or range expansion/contraction, or identifying multispecies associations. With input from attendees, I will then provide a semi-structured, hands-on demonstration of how different modelling goals can be achieved.
I encourage attendees to bring a laptop and to install a recent version of R (e.g., 3.3.1) and appropriate Rtools (if using a windows OS). Attendees will install other necessary software (including INLA and TMB) as we go through tutorials together.
