Sets h so that the species reaches maturity size at the age predicted by the von Bertalanffy growth curve parameters k_vb and (optionally t0) taken from the species parameter data frame. Also needs the exponent b from the length-weight relationship $$w = a l^b$$. If this is not present in the species parameter data frame it is set to b = 3.

get_h_default(params)

## Arguments

params A MizerParams object

## Value

A vector with the values of h for all species
