NS_species_params

This data set is based on species in the North Sea (Blanchard et al.). It is
a data.frame that contains all the necessary information to be used by the
<code>MizerParams()</code> constructor. As there is no gear column, each species is
assumed to be fished by a separate gear.

datasets

A set of classes and methods to set up and run multi-species, trait
based and community size spectrum ecological models, focused on the marine
environment.
