The objective of this research was to study the population dynamics of Mud Crab (Scylla spp.) using length-frequency data collected during May 2012 to April 2013 at a mangrove forest that receives effluent from the Phetchaburi Municipal Wastewater Treatment System at Laem Phak Bia, The King's Royally Initiated Laem Phak Bia Environmental Research and Development Project (The LERD Project), Phetchaburi Province, Thailand. Monthly length frequency data of Mud Crab were analyzed by FiSAT_II. Asymptotic length (L∞) and growth co-efficient (K) were 16.54 cm and 0.29 year-1, respectively. The growth performance index (j/) was 1.90. Total mortality (Z) by length-converted catch curve was 2.81 year-1, of which fishing mortality (F) was 0.94 year-1and natural mortality (M) was 1.87 year-1. The exploitation level (E) of Mud Crab was 0.33. The recruitment pattern was continuous with one major peak in the months of February to June. [ABSTRACT FROM AUTHOR]
