Welcome to the mizer wiki!

Mizer is an R package to run multi-species size-spectrum models of fish communities. The package is on CRAN and therefore available from R's build-it package manager. All info about mizer is currently available in the Vignette embedded in the package.

Mizer can also be used to create web apps that allow users to explore models without the need to install R. An example of such an app investigates the effect of switching to a gear with a T90 extension net to reduce the catches of undersize hake and red mullet.

Mizer is still under active development, currently funded by the European Commission Horizon 2020 Research and Innovation Programme under Grant Agreement No. 634495 for the project MINOUW (http://minouw-project.eu/) and the Australian Research Council Discovery Project ("Rewiring Marine Food Webs").
