Abstract

Runoff of nutrients (N, P, Si) from the mainland would disrupt the balance of nutrients in the waters resulted in changing microalgae communities composition, especially between diatom and dino-flagellate (Dia/Dino). This study was aimed to analyze the relationship of nutrient ratios (N/P, N/Si, Si/P) in the waters, to the density ratio of the Dia/Dino in the coastal and marine waters of Spermonde archipelago, South Sulawesi, Indonesia, which experience nutrient enrichment. Nutrients and phyto-plankton samples were collected from the coastal waters of Tallo, Maros, Pangkep, and seawaters of Spermonde in three seasons (transition, wet, and dry). The results showed the average value (± stan-dard deviation) of Dia/Dino ratio in the coastal and sea waters is 1422±1742 and 1174±1290 in the transition season; 238±205 and 1039±2264 in the dry season; and 153±270 and 72±71in the rainy season. Meanwhile, in the marine waters the ratio of Dia/Dino ranges between 1 and 9839. The ratio of Dia/Dino was not different significantly (p>0,05) by spatial and temporal, but Dia/Dino ratio was different significantly (p<0,05) on the ratio of nutrients in coastal waters, where the value of N/Si ratio tends to ignite monospesies enrichment diatom (Chaetoceros) with a variant of 70,4%. Keywords: nutrient ratios, diatom, dinoflagellate, coastal, Spermonde
