NS_species_params_gears

This data set is based on species in the North Sea (Blanchard et al.).
It is similar to the data set <code>NS_species_params</code> except that
this one has an additional column specifying the fishing gear that
operates on each species.

datasets

based and community size spectrum ecological models, focused on the marine
environment.
