Accuracy of gonadosomatic index in maturity classification and estimation of maturity ogive

Fisheries Research, 2019
Abstract Determination of the stage of sexual maturation of an individual fish is commonly assessed using either microscopic or macroscopic staging. Microscopic staging examines either the internal cellular structure (histology) or the external appearance of the whole-oocyte (whole mount).

Seasonal variations in gonadosomatic index and seminal quality of squirrel monkeys (Saimiri collinsi)

Journal of Medical Primatology, 2022
AbstractBackgroundWe hypothesized that seasonal variations in testicular biometry in Saimiri collinsi are influenced by body mass and that testicular enlargement is related to improved seminal quality. Therefore, the gonadosomatic index (GSI) can be a tool to determine reproductive seasons and the predictors of seminal quality.MethodsBody mass ...

Report on gonadosomatic index, size at firs maturity and reproductive parameters

2018
European anchovy (Engraulis encrasicolus) and European sardine (Sardina pilchardus) have short lifespan and produce many eggs per body mass. Both species usually spawn at 1 year old. In order to understand population dynamics in small pelagic fish in the Mediterranean Sea it is necessary to have a good knowledge on the life-history traits of sardine ...
