14 Biodiversity Conservation: An Imperial Need …

demand for fishes has declined across the world as per the pandemic and fleets
can be seen unoccupied. It has been proposed that the increase in the biomass of
fishes will be seen as fishing is decreased. By the end of April 2020, it was noticed
that the aquatic recovery was in a very anecdotal manner. People are quarantined
in houses due to the lockdown measures reducing the tourism and sojourning of
beaches as a recreation activity. Oviparous animals such as turtles are noticed to
have been laying eggs on the beaches, which was not before due to pollution and
human interference. The river Ganga and Yamuna were having alarming parameters
of pollution, the condition for both the rivers have started to improve Water quality
in the rivers has improved massively including that of Ganga and Yamuna both.
The clearing of water bodies is seen as per the stern enforcement of laws and the
data obtained from the Central Pollution Control Board (CPBB) has manifested
instrumental data in pollution decrease. The data collected at 27 reference points of
river Ganga showed that the water now suitable for human use like bathing and also,
the wildlife and fisheries can be propagated in the water. Another study conducted for
the Lake of Vemba and also showed a decrease in the pollution and improvization
in the water quality. The statistical data are taken through remote sensing images
showed for surface water quality. The concentration of particles decreased by 15.9%
which signifies 8 mg/L decrease which later turned to be decreased by 34% [18]
(Fig. 14.5).
