“…GSI is an ideal way to show the seasonal gonad change for the fishes that are spawning once a year (Barros and Regidor, 2002). The monthly GSI analysis and histological findings showed that ovarium type of A. istanbulensis is group synchronous and this species spawns once in a breeding season for females and males as Alburnus sp.…”

Alburnus istanbulensis (Battalgil, 1941) is a commercially valuable endemic species which exists in the coastal streams of Marmara Region's northern sectors. 317 individuals, which were collected from Darlık Dam, were examined during December 2011-December 2012. The highest GSI values were 13.07±1.63 for females and 6.95±1.28 for males in the beginning of June. The lowest GSI values were observed in August for females (1±0.33) and in September for males (1.05±0.21). By comparing the histological findings with macroscopic observations and GSI values, five developmental stages were determined for females, four developmental stages for males. These findings revealed that A. istanbulensis spawn in June.

“…When comparing the reproductive cycle of O. regia with related species of silversides in South America, two patterns appear: (i) a similar duration of the spawning season among species (ca. 4-6 mo) and (ii) reproduction taking place from the middle of winter to the end of spring (Moreno et al, 1977;Yasuda, 1982;Barros and Regidor, 2002;Favaro et al, 2003). Similar results in the duration and seasonality of the reproductive season have also been reported in other silversides in the northern hemisphere, e.g.…”

“…GSI is an ideal and accepted tool to examine the seasonal gonadal changes and to predict the spawning season of a fish species (Htun-Han, 1978c; Barros and Regidor, 2002;Tsikliras et al 2013). Studies on GSI of M. pancalus indicated variation in GSI values in both males and females during the study period (Fig 1).…”

Background: Macrognathus pancalus or barred spiny eel is a highly valued ornamental and food fish found in the Indian subcontinent. Due to the burgeoning population and their associated impacts, the population of the species is in rapid decline that necessitates time-bound intervention to conserve the species. The current investigation was undertaken to study the gonadosomatic index and gonad histology of Macrognathus pancalus collected from upper Assam, India.Methods: 500 samples of Macrognathus pancalus were collected from different water bodies such as wetlands, ponds, paddy fields, etc. from upper Assam, India during 2018-2019. Monthly samplings were carried out to evaluate the gonadosomatic index. The gonads were dissected out, measured and subsequently preserved for histological studies. Histological sections of preserved samples were prepared by employing accepted methodologies. The sections were then photographed using Leica DM 750 and gonadal staging was ascertained. Result: Gonadosomatic index studies revealed that it peaked in August in both males (3.45±0.18) and females (8.85±0.35), thereby indicating its spawning season. Minimum GSI values were observed during January in males (0.39±0.04) and in December in females (1.04±0.15) indicating the culmination of the breeding period and the advent of the preparatory phase. Macroscopic and microscopic examination unearthed five different phases of gonadal maturation. Gonadal staging through microscopic and macroscopic technique showed synchronicity with GSI values.
