RACIAL STRUCTURE OF HIMALAYAN MAHSEER, TOR PUTITORA (HAMILTON) IN THERIVER GANGA BETWEEN RISHIKESH AND HARDWAR

Study on the racial structure of Tor putitora (Hamilton) was conducted in the foothill section of the river Ganga. Correlation coefficient ( r) was significant at P<0.005 in all the variables except for distance between pectoral and anal fin (DPA) and pre-anal distance (PAD) durin g winter in relation to total length and eye diameter (ED) during mons oon in relation to head length which were significant. The F ratio was significant at P<0.05 in all the variables. The population showed hom ogeneity in the sex, season and year samples. The statistics r.b and F were high for standard length (SL) in relation to total length and po st-orbital distance (POD) in relation to head length.
