  We introduce a fully length-based Bayesian model for the population dynamics
of northern shrimp (Pandalus Borealis). This has the advantage of structuring
the population in terms of a directly observable quantity, requiring no
indirect estimation of age distributions from measurements of size. The
introduced model is intended as a simplistic prototype around which further
developments and refinements can be built. As a case study, we use the model to
analyze the population of Skagerrak and the Norwegian Deep in the years
1988-2012.
