Background

The large, piscivorous Gerrard Rainbow Trout of Kootenay Lake support an important recreational fishery. Intermittently, since 1966, length, weight, fecundity and scale information has been collected from individual fish.

Kootenay Lake Large Piscivorous Trout Hydroacoustic Analysis 2013

Background

Hierarchical Bayesian models were fitted to the hydroacoustic density data and acoustic tag depth detection for Kootenay Lake using using R version 3.0.2 (Team, 2013 ) and JAGS 3.3.0 (Plummer, 2012 ) which interfaced with each other via the jaggernaut (Thorley, 2014 ) R package. For additional information on hierarchical Bayesian modelling in the BUGS language, of which JAGS uses a dialect, the reader is referred to Kery and Schuab (2011) pages 41-44.
