Dataset: OysterFutures simulation model code, input files, and model description

The open-source OysterFutures simulation model was developed to forecast effects of potential management options for oysters in the Choptank and Little Choptank Rivers in Maryland, USA. The model was collaboratively developed with the OysterFutures stakeholder workgroup. The model is written in AD Model Builder (https://www.admb‐project.org/), and the model files are oyster_sim_model2.tpl (the model code), and two data files, oyster_sim_model2.dat and options.dat.

The operating model describes the population and fishery dynamics. The model tracks age classes 0‐14+ (plus group is an aggregate age class for age 5 and older), and has length classes 10 mm‐180 mm+ (the plus group is individuals that size and larger) with a 5 mm bin width. The model operates for 26 years, with two 6‐month time steps annual, with the initial values set in year 0 at the most recent estimates of abundance.
