This dataset includes the source computer code and supporting data files for the predator-prey simulation model (parameterized for summer flounder, Paralichthys dentatus) developed to investigate bottom-up effects defined to be temporal pulses in prey abundance on predator growth, production, and fisheries management. The model is age-structured and spatially explicit to accommodate ontogenetic dietary changes and seasonal migrations, respectively. Three general prey groups were modeled and assumed to be small crustaceans, forage fish, and larger fish prey. The code was written in R by Andre Buchheister.

The dataset includes:
Source computer code (core simulation): PredPreySim.r
Source computer code (graphing results): PredPreySim_Graphing.r
Data file (stock recruitment): Stock_Recruitment.csv
Metadata file (simulation model parameter descriptions): Parameter_Categories.csv
Data file (summer flounder growth): LW_Age.csv
