MORPHOMETRIC STUDY ON MACROBRACHIUM ASSAMENSE PENINSULARE (TIWARI, 1958) FROM RAWASAN STREAM OF GARHWAL HIMALAYA, UTTARAKHAND, INDIA

Abstract: Nineteen morphometric characters of Macrobrachium assamense peninsulare (Tiwari, 1958), a freshwater prawn were measured from 37 males and 41 females collected randomly. Statistical analysis was performed to analyze the intra population variation in Macrobrachium assamense peninsulare from Rawasan stream in Garhwal region, Uttarakhand, India. A significant positive correlation was obtained in between the parameters considered at the 1 % level of significance excluding some chelipeds parameters. Regression analysis was performed for three morphometric variables viz., Carapace length (CC) with Abdominal length (CA) and Carapace length (CC) with Rostral length (RL) and fitted regression equation y = 1.2789x + 5.8026 (R² = 0.7031) and y = 0.3675x + 1.8288 (R² = 0.6875) in female; y = 1.3456x + 4.7359 (R² = 0.7749) and y = 0.3719x + 2.138 (R² = 0.6714) in male respectively were obtained from the species.
