Abstract:
Species composition, phytoplankton abundance, and relative yield of variable fluorescence (F_v/F_m) were determined in the mesotrophic Nhatrang Bay in October-November 2004. Species diversity (250 taxonomic units) and heterogeneity of the phytoplankton structure were high. With respect to number of species and their abundance, diatoms prevailed. In selected parts of the bay, dinoflagellates dominated. Average biomass in the water column under 1 m**2 (Bt) varied from 2.3 to 64.4 mg C/m**3 (av. 31.0 mg C/m**3). Bt values were the lowest at stations nearest to the river mouth. Seaward, Bt increased. Bt values increased with depth at some stations and decreased at others. In surface layers biomass was lower than that in the underlying waters. F_v/F_m values ranged from 0.10 to 0.64 (av. 0.49). The lowest F_v/F_m values were observed in the area close to the seaport. Over greater part of the bay, F_v/F_m values were higher than 0.47. Such values are indicative of relatively high potential of photosynthetic activity of phytoplankton. Abundance and species diversity were higher than those in the dry season (March-April).
