Occurrence of massive blooms of dinoflagellates and other phytoplankton species in the coastal waters indicate the health condition of coastal waters. Dinoflagellate blooms reported around the world are known to be harmful to the coastal marine flora and faunal communities. Therefore monitoring such blooms occurring in the coastal waters are important to monitor coastal water pollution and to make better management strategies towards coastal water quality. In the present study, massive bloom of dinoflagellate Protoperidinium  pallidum was observed in Tuticorin Bay, southeast coast of Tamil Nadu, India. High densities of Protoperidinium  pallidum population of 12×105 cells ml−1 was recorded during this bloom. Occurrence of Protoperidinium  pallidum bloom recorded in this study is the first report from Tuticorin, Gulf of Mannar region, Tamil Nadu.
