The NOAA Fish and Fisheries Toolbox (Fish-Tools) is a collection of software programs and modeling tools which can be used in fishery stock assessments. Many of the models are used in peer-reviewed stock assessments in the U.S. and globally. A variety of fisheries stock assessment models as well as analytical and reporting tools are available, each of which uses a different type of estimation method to produce results. The NOAA Fish and Fisheries Toolbox (Fish-Tools) is part of the NOAA Fisheries Integrated Toolbox (FIT) and is an expansion and update to the NOAA Fisheries Toolbox
