Simulation tools for management strategy evaluation are provided for the DLMtool operating model to inform data-rich fisheries. MSEtool provides complementary assessment models of varying complexity with standardized reporting, diagnostic tools for evaluating assessment models within closed-loop simulation, and helper functions for building more complex operating models and management procedures.
The main features of MSEtool are the assessment models and the ability to make model-based management procedures by combining assessment models with harvest control rules. Such MPs can be used and tested in management strategy evaluation with DLMtool operating models. An overview of these features is available in the MSEtool vignette.
The following assessment models are available:
Surplus production (SP, SP_SS, SP_Fox, and
Delay difference (DD, cDD, DD_SS, and cDD_SS)
Statistical catch-at-age (SCA, SCA2, and SCA_Pope)
Simple Stock Synthesis (SSS which implements SCA_Pope with fixed depletion assumption)
SRA_scope model can be used to condition DLMtool operating models from real data. Information can be found
MSEtool also contains multiMSE, a platform for multi-stock and multi-fleet operating models based on components from DLMtool. An overview of multiMSE is available in the multiMSE vignette.
All MSEtool vignettes can also be viewed by typing
browseVignettes("MSEtool") into the R console or through the
MSEtool webpage on CRAN.
See the DLMtool User Guide for a detailed description of how to use the DLMtool package.
See the Data-Limited Toolkit Website for more information on DLMtool, including an interactive demo of the main features of the toolkit, information on case studies where the toolkit has been applied, and more about the history and development of the DLMtool.
