Description During February-April 1987 an intense bloom of Noctiluca miliaris Suriray was observed in the lower reaches of the Mandovi and Zuari estuaries and the coastal waters of Goa. The bloom also extended from Mangalore to Malvan. During the bloom period chlorophyll a concentration was as high as 16.70 mg m-3 and N. miliaris contributed to 91.3% of the total phytoplankton (51,360 counts 1-1). The bloom imparted green colouration due to the presence of a flagellate Pedinomonas noctilucae (Subr.) Sweeney in large numbers. Midwater trawl catch during the period showed substantial fall in fish catch. The prevailing environmental conditions and possible impact on local fisheries during such blooms are discussed
