In this study, the composition and distribution of phytoplankton pigments its relation to nutrients light was investigated, an elaboration using it as a proxy for group followed, in different nutrient-level tropical bays Indonesia. Phytoplankton pigment analysis by High Performance Liquid Chromatographer (HPLC) resulted set chlorophyll-a (Chl-a), chlorophyll-b (Chl-b), chlorophyll-c (Chl-c), lutein, zeaxanthin, fucoxanthin, peridinin, diadinoxanthin, ß-carotene. Linear multi regression multivariate principal component (PCA) showed that algae correlate positively with are not significantly correlated underwater water transparency, suggesting important roles development estuaries. There were differences total concentration between (p < 0.005), showing eutrophic system Jakarta Bay highest (mean 10.55 μg L−1), Lampung second 3.37 lowest oligotrophic waters Semangka 0.80 L−1). At all studied, high nutrient sites, which located river mouths inner part bay, always characterized concentration. Pigment had correlation composition: diatoms dinoflagellates peridinin Chl-c, Chlorophyceae Chl-b lutein. This conformity suggests can be used biomarker determination along microscopic species identification.
