Abstract:
The reproductive biology of gora chela, Securicula gora (Hamilton, 1822), in the Narmada River was examined from July 2021 to January 2022. A total of 116 gora chela, Securicula gora (Hamilton, 1822) fish samples were obtained from the Narmada River in Madhya Pradesh, India. The highest Gonado somatic index (GSI) value was obtained in September (20) month during the seven months of monitoring of female gora chela fish. In comparison, samples obtained between November and January (0.57-2.53) showed lower levels. The fish with the highest fecundity was 16864 (TL 13 cm and BW 19.04 g). The mean fecundity was calculated to be 7162±5543.26, indicating that gora chela is a fairly fecund fish. During the month of September, the ova varied in size from 0.05 to 2.10 mm, whereas the mature eggs of Securicula gora (Hamilton, 1822) were spherical with diameters ranging from 0.90 to 2.10 mm. There were five gonadal developmental phases noted. Monthly mean ova diameters recorded were as follows: July (0.248±0.12 mm), August (0.441±0.13 mm), September (1.298±0.39 mm), October (0.118±0.17 mm), November (0.00±0 mm), December (0.032±0.06 mm) and January (0.09±0.09 mm). Since a consequence of the findings, it was established that fish spawn more than once, since immature and maturing, ripe, and immature ovaries were detected in the same size group of females. The fecundity, ova diameter, and gonadal developmental stages of the same species in various populations may be due to eating, reproductive activity, and climatic factors.
