This study was carried out through monthly deep trawls applications in the waters of 0-50m, 50-100m and >100m of depths in Babadillimani Bight between June 1999-April 2000. There was a linear relationship between carapace length and total length in males and females CL = -0.2257+0.2243(star)TL (R-2 = 0.9216, n = 923) for males, CL = -0.2148 + 0.222(star)TL (R-2 = 0.9649, n = 2859) for females, and CL = 0.0952+0.2223(star)TL (R-2 = 0.9652, n = 3886) for total individuals. As to equation of relationship between carapace length and weight, it was W = 0.0015(star)cL(2.6252) for males, W = 0.0009(star)cL(2.8190) for females, and W = 0.001(star)CL(2.7954) for total individuals. The von Bertalanffy growth constants in length was CL infinity = 31.20mm, K = 0.76/year, t(0) = -0.386 year, C = 0.65, WP = 0.65 for males; CL infinity = 32.30mm, K = 0.77 year(-1), t(0) = -0.387 year, C = 0.80, WP = 0.57 for females; and CL infinity = 32.10mm, K = 0.76 year(-1), t(0) = -0.394 year, C = 0.60 and WP = 0.65 for total individuals including juveniles as well as sexually maturated ones. In the study, for all the individuals of the species, the total (Z), natural (M) and fishing (F) mortality coefficient and exploitation rates (E) were determined as 4.00, 1.29, 2.71 and E = 0.67 year(-1), respectively.
