Plankton Communities and Physicochemical Properties in Seawater Post Tsunami 2004 Damaged in Phang Nga Province, Thailand

Abstract:

The plankton communities (phytoplankton and zooplankton) and physicochemical properties in seawater were monitored between January to December 2008 at nine coastal mariculture and local fisheries piers in Phang Nga Province, Thailand, to assess water quality rehabilitation following the Tsunami disaster of 2004. All physical and chemical values fell within the ranges that are considered normal for unpolluted water: temperature ranged from 29.84 (± 0.47) - 31.29 (± 0.27) °C; transparency ranged from 49 (± 7) - 108 (± 7) cm; total dissolved solids ranged from 17,060 (± 162) - 26,240 (± 68) mg/l; electrical conductivity ranged from 34.12 (± 3.48) - 52.48 (± 1.62) mS/cm; pH ranged from 6.69 (± 0.13) - 7.94 (± 0.07); salinity ranged from 19.48 (± 1.78) - 30.28 (± 0.44) ppt.; dissolved oxygen ranged from 6.36 (± 0.35) - 7.49 (± 0.35); biochemical oxygen demand ranged from 2.04 (± 0.25) - 3.80 (± 0.20) mg/l; and chemical oxygen demand ranged from 34.0 (± 0.95) - 63.3 (± 0.84) mg/l. Phytoplanktons were recorded to Euglenophyta, Chlorophyta, Chrysophyta, Cyanophyta and Pyrrhophyta. Zooplanktons were determined to six Phyla i.e. Chordata, Annelida, Arthropoda, Rotifera, Mollusca and Protozoa.
