Abstract
The length-weight relationship of males and females of Harpiosquilla harpax collected at Visakhapatnam were W = 0.00007985 L2.5650 and W = 0.00004792 L2.6622 respectively. A single length-weight relationship is given for both the sexes as W = 0.00006554 L 2.6015. Analysis of covariance conducted to test the difference between the regression slopes of males and females of H. harpax showed significant differences (P < 0.05). Relative condition factor for males and females was given for this study. The age and growth were estimated by applying ELEFAN 1method; it confirmed the longevity of the stomatopod to be 86 months. The growth rate was high during the first year and then it declines during subsequent years. The Von Bertalanffy?s growth parameters were L = 220.50, K = 1.5 /yr?, t0 = 0.06 and ? = 4.8629/Yr. respectively.
