Morphological account of Schizothorax richardsonii population of river kosi and river Alaknanda

Vibha Lohani, Bonika Pant, NN Pandey and RN Ram
Morphometric relationship of Snow trout (Schizothorax richardsonii) has been studied from two different lotic water bodies of Uttarakhand-river Kosi and river Alaknanda. The descriptive statistical parameters and correlation coefficient (r) were analysed with independent variable (total length) and dependent variable (other morphometric parameters). The linear relationship has been observed between dependent and independent characters. The highest correlation was shown by standard length with total length in both the rivers. It was observed that significant correlation exists in all the morphometric characters with total length except pre orbital length, eye diameter, dorsal fin length, and anal fin base length, termination of anal to dorsal side caudal peduncle and termination of anal to ventral side caudal peduncle in river Kosi. The significant correlations exist in all the morphometric characters with total length except dorsal fin length in river Alaknanda. Twenty one characters have been studied in percentage of total length from which twelve characters were intermediate controlled in both the selected ecosystems which showed little bit disturbance in environmental conditions.
