Abstract
Blooming of diatom species Chaetoceros curvisetus (Cleve, 1889) was observed in Junglighat Bay and Haddo Harbour of Port Blair Bay of Andaman and Nicobar Islands during June 2010. Physico-chemical parameters, nutrient concentrations and phytoplankton composition data collected from five stations during 2010 were classified as bloom area (BA) and non-bloom area (NBA) and compared. Elevated values of dissolved oxygen were recorded in the BA, and it significantly varied (p < 0.01) from NBA. Among the nutrient parameters studied, nitrate concentration indicated significant variation in BA and NBA (p < 0.01). Phosphate and ammonia concentrations reduced to below detection level (BDL) in the BA and NBA, indicating its utilization. In Junglighat Bay, the C. curvisetus species constituted 93.4 and 69.2 % composition of total phytoplankton population during day 1 and day 2, respectively. The bloom forming stations separated out from the non-bloom forming station in non-parametric multidimensional scaling (nMDS) ordinations; cluster analysis powered by SIMPROF test also grouped the stations as BA and NBA.
