Survey on Biotic Communities of The Ganga River System Around Prayagraj
(Allahabad), India
A survey was conducted on the biotic communities of the Ganga River system around Prayagraj at Mehdauri, Shivkuti (River Ganga) and Gaughat, Sadiapur (River Yamuna) during 2017-18. Plankton and benthos showed identical pattern at all the centers investigated. Peak production of plankton was observed during summer months and their minimum number was recorded in monsoon months. Abundance of chironomids, bivalves and gastropods were recorded. Maximum values of phytoplankton were recorded 1413 units.l-1 and benthos 464 units.m-1 in the Ganga River System. Possible detrimental factors responsible for biota fluctuations are also discussed.
