Original language description
Pachypterus khavalchor (Kulkarni, 1952) is a rarely studied but highly exploited catfish species inhabiting the Krishna River system of India. A total of 427 fishes were collected monthly from the Panchaganga River to study its reproductive characteristics. Samples were analysed for length-weight morphometry, sexual dimorphism, gonad weight, and maturity status. Gonadosomatic Index (GSI), hepato-somatic Index (HSI), and stomach fullness index (SFI) were estimated to assess reproductive periodicity and its correlation with the fish condition and energy dynamics. Males had a cone-like genital papilla as a sexually dimorphic character. The male-female ratio was 1:1,02 (not different from 1:1) and females were comparatively larger than the males. Males matured at smaller sizes (7,3 cm) as compared to females (8,9 cm). The absolute fecundity varied from 932 to 24642 eggs.fish-1 while the relative fecundity ranged from 226 to 723 eggs.g -1 of body weight. Regression analysis revealed a significant
