Description Usage Arguments Value Examples
This function allows you to estimates the growth rate K
and the theoretical maximum size Linf
from a dataset made of Age
and length
measurements using teh method described in Kimura D.K.,(1980) Likelihood methods for the von Bertalanffy growth curve. Fishery Bulletin 77: 765<e2><80><93>776.
