摘要: The possibility of translocation organisms via ship's ballast water (BW) during a voyage from Hazira on the west coast to Visakhapatnam east India was assessed. Samples BW and discharge sediment collected subsequent were analyzed for different abiotic biotic components. It observed that salinity did not change, whereas temperature pH increased marginally voyage. A marginal increase in dissolved oxygen is rough-very rough sea conditions. sharp decline phytoplankton zooplankton abundance initial tank sample compared natural seawater indicates impact pumping plankton community. Changes state (slight-moderate rough) resulted higher suspension rate suspended particulate matter this coincided with bacterial followed by phytoplankton. An could be attributed inoculum sediment. decreased start till end voyage, high numbers dead sample.
