Using the gonadosomatic index to estimate the maturity ogive: application to Chilean hake (Merluccius gayi gayi) [PDF]

open access: yesICES Journal of Marine Science, 2014
Abstract The proportion of mature fish at age or length is one of the most important population attributes in assessing reproductive potential. This proportion is usually named the maturity ogive. The most crucial step in estimating this proportion deals with maturity staging assessed by macroscopic or histology analysis.
