Abstract
The paper deals with the analysis of reproductive capacity of Puntius conchonius (Ham.-Buch.), an important ornamental fish inhabiting the river MandaI in Garhwal Himalaya. Study is based on 73 mature female specimens in a length ranging from 53 to 79 mm were collected from river Mandal. The absolute fecundity ranged from 523.0 1± 100.3 ( fish length 54.2 ± 1.I mm, fish weight 2782.5 ± 84.6 mg, ovary length 17.5 ± 1.2 mm and ovary weight 250.1 1 12.7 mg) to 1366± 282 (fish length 77.4±1.4 mm, fish wight 8408 ± 861 mg, ovary length 26.2 ± 2.2 mm and ovary weight 584.7 ± 112.7 mg). Four linear relationships were observed between fecundity and different body parameters calculated by the method of least squares. Sex ratio of fish in nature was also studied monthly, which varied from 1:1 (April) to 1:1.8 (July) with an annual average I :1.17 (male: female, X 0.013 which is insignificant) .Overall it was found very close to the natural one.
