Accuracy of gonadosomatic index in maturity classification and estimation of maturity ogive
Fisheries Research, 2019Abstract 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).

Using gonadosomatic index cut-off scores has become a standard protocol for selecting reproductive fish in studies on the reproductive biology of round goby, Neogobius melanostomus, a significant invader of the Laurentian Great Lakes, but the validity of this practice has not been validated with histological staging.

Marine Pollution Bulletin, 2011
Proteomics is a new and promising approach to evaluate potential effects of pollution. In order to investigate if there is a direct link between the protein expression profiles obtained by the SELDI-TOF MS technology and effects observed at the organism level in fish, plasma samples from unexposed and 20 ppb alkylphenol exposed female Atlantic cod ...

A reproductive study was conducted on 305 individuals of common pandora Pagellus erythrinus, from Mazarron Bay (Murcia, southeast coast of Spain), providing information for a more adequate interpretation of the gonadosomatic index in this species and its relationship with the stage of maturity of the fish.

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
2018European 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 ...
