Spatial distribution management of Crustacea (Decapoda) based on conservation in tropical tidal lake

Abstract. Muhtadi A, Yulianda F, Boer MF, Krisanti M. 2022. Spatial distribution management of Crustacea (Decapoda) based on conservation in tropical tidal lake. Biodiversitas 23: 4064-4072. Siombak Lake has a unique biological system impacted by high and low tides. Crustaceans found this lake are predicted to establish distinctive communities due their interaction with two systems seawater freshwater. Therefore, study aimed determine the characteristics crustacean Lake, which were influenced Crustacean samples taken observed every month at tides traps from September 2018 August 2019. The crustaceans discovered included 5 families 18 species, 13 crabs shrimp. communities' is extremely dynamic, as seen emergence mangrove tide fiddle during tide. more ecology, characterized higher abundance individuals Furthermore, density fluctuates throughout year reaches highest March 8679 ind/100m2. Penaeid shrimp always tides, dominated Parapenaeopsis coromandelica, while only efforts required conserve enhance habitats for sustainable usage.
