An individual-based model (IBM) incorporating within-population variability in von Bertalanffy growth, size-dependent natural mortality, and a size-selective fishery to simulate an exploited fish population and catch (harvest). A bootstrap algorithm allows the user to investigate various sampling approaches including sampling strategy (proportional or fixed otolith sampling, POS or FOS, respectively), sample size, supplementation with fishery-independent sampling, and assumptions regarding von Bertalanffy t0 and the relationship between variance of length at age and age. A function to produce plots of the bootstrap sampling results is also provided.
Code to inform fishery dependent biological sampling from simulated fish populations and resulting catch using an individual based model. For additional details see Schemmel et al 2022 (https://academic.oup.com/icesjms/article/79/5/1497/6581603).
