7  Mizer

Mizer is an R package to run dynamic multi-species size-spectrum models of fish communities. The package has been developed to model marine ecosystems that are subject to fishing. However, it may also be appropriate for other aquatic ecosystems. By providing a framework for multi-species fisheries modelling as an R package, mizer enhances the accessibility, usability, and reproducibility of models, and thus aims to facilitate collaboration and innovation.

The package contains functions that allow you to set up an ecosystem model and then project it through time under different fishing strategies. Methods are included to explore the results, including plots and calculations of community indicators such as the slope of the size spectrum. Size-based models can be complicated, so mizer contains many default options that you can however change when needed.
