Anika Parmar, Narinder Pal Bhatia
Age and growth of Cirrhinus mrigala
from Pong reservoir of the Kangra district of Himachal Pradesh was studied by using scale method. Length-weight relationship was analyzed by using Le Crenâ€™s equation W=aLn which was further transformed into Log W=log a+n log L. In the present study, Log W was found to be -0.401745082 L3.2848. Linear relationship with a high degree of correlation was observed between total length and lateral scale radius. Six age classes (3-8) were reported in the present study. Maximum numbers of specimens were reported in the age class 4. The data on growth characteristics revealed that age class 4 is more vulnerable in the catch. Annual increment (h) and index of species average size (Ç¾L) were also calculated from the data.
