Abstract

Incubation experiments were carried out on-board under natural illumination condition to the assessment of net primary production of the river Buriganga. The net primary production (NPP) of the river Buriganga were found 147.73 ± 1.8 µgCm-2d-1 and 66.48 ± 1.9 µgCm-2d-1 in day-1 of wet and dry season respectively. The productivity was gradually decreased by time during the incubation period. The net primary productivity of the river were very small unit due to heavy pollution by the chemical and organic wastes. The concentration of dissolved oxygen (DO) in this water body were very low which is so difficult to survival of aquatic life in water of Buriganga.
