“…The bloom end when one of the nutrients required runs short so the cell masses of N. scintillans becomes unable to multiply (Van den Bergh et al 2002). Harmful algal bloom incidents caused by dinoflagellates are increasing around the world causing ecological damage during the decades (Al Kindi et al 2007).…”

The Noctiluca scintillans (Macartney) Kofoid & Swezy a dinoflagellate of marine environment can form bloom and generates substances that are noxious to aquatic organisms. An intense bloom of the N. scintillans in Gadani, Baluchistan coast along Northern Arabian Sea is reported in the present study. Sea water was collected using Niskin water sampler from three locations for water quality and nutrient analysis. Maximum number (6780 cells/l) of phytoplankton cells were observed in Station-I than that of Station-II (4180 cells/l) and in Station III (3580 cells/l). Maximum number (2740 cells/l) of Noctiluca was observed in station I than station II (1020 cells/l) and minimum (620 cells/l) in Station III. Among toxic species of dinoflagellates, Alexandrium tamaresence, Ceratium fusus, Dinophysis caudata, Gyrodinium spirale, Prorocentrum micans, Prorocentrum arcuratum and Scrippsiella trochoidea were observed. The Noctiluca scintillans can transfer toxins to higher trophic levels by grazing these toxic dinoflagellates. The increase in intensity of algal blooms occurring in marine waters cause detrimental effects including bio toxins, physical damage and the anoxia which caused massive fish mortality, affect fishery resources, biodiversity and vulnerable to the aquatic ecosystem.

Red tide, one of the harmful algal blooms (HABs) is a natural ecological phenomenon and often this event is accompanied by severe impacts on coastal resources, local economies, and public health. The occurrence of red tides has become more frequent in Omani waters in recent years. Some of them caused fish kill, damaged fishery resources and mariculture, threatened the marine environment and the osmosis membranes of desalination plants. However, a number of them have been harmless. The most common dinoflagellate Noctiluca scintillans is associated with the red tide events in Omani waters. Toxic species like Karenia selliformis, Prorocentrum arabianum, and Trichodesmium erythraeum have also been reported recently. Although red tides in Oman have been considered a consequence of upwelling in the summer season (May to September), recent phytoplankton outbreaks in Oman are not restricted to summer. Frequent algal blooms have been reported during winter (December to March). HABs may have contributed to hypoxia and/or other negative ecological impacts.
