Abstract:
A study on morphometric relationship of Silver carp (Hypophthalmichthys molitrix) was conducted on the fish specimens followed by estimation of water quality and qualitative assessment of plankton community in a fish farm of Tarai region of Pantnagar, Uttarakhand. The descriptive statistical parameters and correlation coefficient (r) were analysed with independent variable (total length) and dependent variable (other morphometric parameters). The result shows that morphometric parameters are significantly correlated to total length except caudal length. The maximum correlation coefficient of average total length was obtained with fork length having a value of 0.992 and minimum with caudal length with value of 0.323. The average values of Temperature (°C), pH, TDS (mgl^-1), DO (mgl^-1), CO₂ (mgl^-1) were 27.2, 7.5, 287, 6.0 and 1 respectively. The qualitative analysis of the community resulted in 6 and 2 species of phytoplankton and zooplankton respectively. Water quality parameters and diversity of plankton community revealed the conducive environment of the water body.
