The objectives of this study were to determine the harmful species of dinoflagellates, to determine the concentration of nutriens in surface waters, and to analyze factors affecting the ecological aspects of the harmful dinoflagellates. The results showed that there were 7 genus of dinoflagellates found in this study i.e., Ceratium spp., Gymnodinium sp., Dinophysis sp., Gonyaulax sp., Noctiluca sp., Protoperi-dinium spp., and Peridinium sp. Protoperidinium spp. and Ceratium spp. were the predominant species, with their abundance ranged of 9-659 cells/L and 6-556 cells/L, respectively. In temporal scale, values of DO and water light penetration were not significantly different (α>0.05), while for the parameter of nutriens, salinity, and abundance were significantly different (α<0.05). Total abundance of dinoflagellates was significantly correlated with nitrate, nitrite, ammonia, phosphate, salinity, and DO. Harmful dinoflagellate species such as Dinophysis sp. (DSP), Gymnodinium spp. (NSP and PSP), Noctiluca sp. (anaerobic), and Gonyaulax sp. (anaerobic) were observed in the study area. The high concentration of ammonia (>1 mg/L) in the waters of Losari beach also indicated that the area was affected by anthropogenic activities. Minimizing nutrient inputs from the land was becoming the most priority measure to be done to avoid such effects related to dinoflagellate harmful algae bloms.Keywords: anthropogenic, dinoflagellates, harmful species, Makassar, nutrients.

“…Documented accounts of Pseudo-nitzschia bloom "patches" in Irish waters point to a heterogeneous distribution (horizontal and vertical) off the south and southwest coasts (Cusack 2002, Farrell et al 2012. In this study, a clear association between Pseudonitzschia bloom dynamics and upwelling events (via the "Wind Index") is evident off southwest Ireland.…”

“…These structures protect the integrity of the HAB species patch until the eddy disperses at the coast and the HAB organisms within it are released and thereby cause harm. Local reduction in horizontal and vertical dispersal can facilitate the formation of small (7 km in diameter and about 3 m thickness at 20 m depth) but high-density patches of Dinophysis acuta cells (10 4 -10 5 cells L -1 ) in open waters off southern Ireland (Farrell et al, 2012).…”
