Gonosomatic index of female Discognathus modestus were studied during one year The experiments were conducted from January 2016 to December 2016 After dissecting gonads were preserved in 10 % formalin Results showed that Discognathus modestus is a heterosexual fish Gonads were fully developed during the month of June July, and August when the GSI were the highest,

Previous studies have successfully applied various methods based on the gonadosomatic index GSI to improve accuracy in determining maturity stage McQuinn 1989; Vitale et al 2006; McPherson et al 2011 These studies allowed immature fish to be separated from spent or recovering fish and identified the degree of maturity for females when neither histology nor macroscopic analyses were available,

 · The gonosomatic index is also divergent between the male morphs Figure 4b, and is close to ninefold greater in type II males who may invest close to 20% of their weight in testes, compared to only 1% among type I males, Gravid females resemble type II males in having a large gonosomatic index, although that of females is indeed greater, Both gravid females and type II males have a distended and firm belly, …

Abstract 1, 1, Using data collected from two teleostean fish species the assumptions of the gonosomatic index GSI were examined primarily by regression analysis and analysis of covariance, 2, 2, Standard length of the fish and standard length cubed can have a higher degree of correlation with ovarian weight as compared to body weight, Therefore, an ovarian weight-body weight ratio is not

Gonadosomatic index GSI gives the proportion of the ovary weight to the total fish weight, weight after fat extraction, and fat content [%] for males and females, gonadosomatic index [GSI, %] for males only, and fecundity [number of developing embryo], reproductive allocation [RA, %], embryo dry mass [mg], offspring lean weight [mg], and embryo

Gonadosomatic index which is an index of gonad size relative to fish size is a good indicator of gonadal development in fish [2] The percentage of body weight of fish that is used for production of eggs is determined by the gonadosomatic index

Using the gonadosomatic index to estimate the maturity

The gonadosomatic index, abbreviated as GSI, is the calculation of the gonad mass as a proportion of the total body mass, It is represented by the formula: [1] GSI = [gonad weight / total tissue weight] × 100

 · This ratio gonadal weight/body weight x 100 is termed the gonosomatic index GSI, Nikolsky 1963, in fact, states that, “the effects offish size on gonadal weight are eliminated by expressing gonadal weight as a percentage of body weight”, Thus, in work with fishes, the GSI is widely used as an index of gonadal activity and as an index for spawning preparedness, Moreover, it is common for researchers studying reproduction to use the GSI …
