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.
