dc.description.abstract | Monthly length-frequency data of spiny lobster Panulirus homarus collected from the south coast of Sri Lanka during 1988-1990 were analyzed to estimate von Bertallanfy growth parameters. The asymptotic lengths estimated using Wetherall plots were 322 mm and 315 mm total length for the males and females, respectively. Using o' values of 3.53 for males and 3.61 for females, the growth constant (K) was estimated as 0.21 year super(1) and 0.27 year super(1) for the males and females, respectively. The estimates of natural and total mortality (M and Z) are 0.98 year super(1), 1.96 year super(1) for males and 0.92 year super(1), 1.54 year super(1) for females respectively. Recruitment appears to occur in two pulses per year. | |
