Example species parameter set based on the North Sea with different gears

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

Usage

NS_species_params_gears

Format

A data frame with 12 rows and 8 columns. Each row is a species.

species: Name of the species
w_max: Maximum size.
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
gear: Name of the fishing gear

Examples

params <- MizerParams(NS_species_params_gears)
#> 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.
