Description |
Phytoplankton pigments and abundance of zooplankton in the Narmada Estuary, Bukki Creek and Dahej Creek were studied from March to September, 1979. The river sustained an appreciable quantity of phytoplankton pigments with relatively higher values towards the upstream stations. Mean chlorophyll was highest during the premonsoon period (31.48 mg/m3) and lowest (7.8 mg/m3) in the monsoon period. Average value of chlorophyll showed a rise in the postmonsoon period (19.3 mg/m3). Zooplankton abundance in the river was not very high and mean biomass was maximum in September (2.72 m3/100 m3). The lowest biomass was in the monsoon period (0.41 ml/100 m3). During the premonsoon period zooplankton biomass was moderate (1.68 ml/100 m3). Copepods, decapod larvae, molluscan veligers, fish larvae and fish eggs were the most common groups in the collections. Incidence of chaetognaths in the river was in accordance with the prevailing salinity regime. Diversity of zooplankton was greater towards the mouth region. Biological characteristics of Dahej creek were comparable to that of the Narmada mouth while that of Bukki Creek were similar to the upstream stations of the river
