Impact of barge movement on phytoplankton abundance and biomass was assessed in the
lower stretch of river Ganga, popularly known as Bhagirathi-Hooghly river, during April 2016
to March, 2017. Based on the magnitude of tide, intensity of shipping and boating activities,
the stretch from Baranagar to Lalbag (278 km), located at latitude (22˚38’33.41"N to 24˚
10’59.75"N) and longitude (88˚21’21.29"E to 88˚16’5.65"E) was divided into three zones viz.
zone—I (Baranagar to Barrackpore), zone II (Triveni to Balagarh) and zone III (Nabadweep
to Lalbag). Water samples were collected randomly from six stations covering 22 barge
movements at their passage at three different time intervals viz., 30 minutes before ‘barge
movement’, during ‘barge movement’ and 30 minutes after ‘barge movement’. Analysis
revealed the presence of 52 phytoplankton taxa belonged to 5 phylum during the study
period. The abundance of phytoplankton was highest in zone—I followed by zone III and the
zone II. A 44% decrease (1,997 ±1,510 ul-1) in phytoplankton abundance was observed dur ing ‘barge movement’ with respect to normal condition (3,513 ± 2,239 ul-1) which could be
due to propeller turbulence in the passage. Cell damage study revealed 21% damage in
phytoplankton cell structure in ‘during barge’ followed by ‘after barge’ (10%) condition com pared to natural state (6%). Study revealed that phytoplankton biomass (Chlorophyll a) was
influenced by ‘barge movement’ in the sampling stretches and the impact was assessed by
one way ANOVA. The effect was found significant at Barrackpore (p
