This chapter describes the forms used to run Ecosim ([EwEugRunEcosim Run Ecosim], [EwEugEcosimPlot Ecosim plots], [EwEugEcosimResults Ecosim results] and [EwEugStockRecruitmentPlot Stock-Recruitment plot]), as well as important Ecosim tools: [EwEugMonteCarloRuns Monte Carlo runs],[EwEugFishingPolicySearch Fishing policy search] and [EwEugFitToTimeSeries Fit to time series].
