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 MizerParams() constructor. As there is no gear column, each species is assumed to be fished by a separate gear.

Usage

NS_species_params

Format

A data frame with 12 rows and 7 columns. Each row is a species.

species

Name of the species

w_max

The size at which the population invests 100% of its income into reproduction so that all growth stops.

w_mat

Size at maturity

beta

Size preference ratio

sigma

Width of the size-preference

R_max

Maximum reproduction rate

k_vb

The von Bertalanffy k parameter

w_inf

The von Bertalanffy asymptotic size

Source

Blanchard et al.

Examples

params <- MizerParams(NS_species_params)
#> Note: No sel_func column in species data frame. Setting selectivity to be 'knife_edge' for all species.
#> Note: No knife_edge_size column in species data frame. Setting knife edge selectivity equal to w_mat.
#> Note: No h column in species data frame so using f0 and k_vb to calculate it.
#> Note: No gamma column in species data frame so using f0, h, beta, sigma, lambda and kappa to calculate it.
#> Note: No ks column in species data frame so using ks = h * 0.2.
#> Note: No m column in species data frame so using m = 1.
#> Using z0 = z0pre * w_max ^ z0exp for missing z0 values.
