Water quality and phytoplankton diversity of Gopeswar temple freshwater pond in Assam (India)

Abstract

Water quality and phytoplankton diversity were investigated in Gopeswar temple pond of Assam, India. Altogether 45 species of phytoplankton were recorded representing Chlorophyceae (16), Cyanophyceae (10), Bacillariophyceae (14), Euglenophyceae (3), Chrysophyceae (1) and Dinophyceae (1). Phytoplankton peaks were observed in summer and monsoon periods. Correlations of phytoplankton density with different water quality parameters were evaluated and the water body was found to be moderately polluted. Presence of Microcystis aeruginosa along with Navicula cryptocephala throughout the year also indicated its cultural eutrophication and hence, needs management intervention DOI: http://dx.doi.org/10.3329/bjb.v41i2.13446 Bangladesh J.

Water quality and phytoplankton diversity of Gopeswar temple freshwater pond in Assam (India)

“…In India, recently the diversity of phytoplankton in different freshwater wetlands along with their physicochemical characteristics were studied (Veereshakumar and Hosmani 2006, Ravikumar et al 2006, Tiwari and Shukla 2007, Senthilkumar and Das 2008. Though there are more than 3513 inland freshwater bodies including a good number of temple ponds in North Eastern Region of India, a little work have so far, been done on algal diversity of those water bodies (Baruah and Kakati 2009). The present work is an attempt to explore the phytoplankton species, their composition along with their correlation with different physicochemical parameters of the Gopeswar temple pond.…”

Phytoplankton Diversity of a Demineralized Urban Wetland of Meghalaya State of Northeast India: The Spatio-temporal Variations and the Role of Abiotic Factors

“…Sixty-four species (S) known from our net plankton collections reveal notably rich phytoplankton as compared with the reports from Assam [23,24,[42][43][44][45][46][47] , Meghalaya [10][11][12][13] , Mizoram [9] , Sikkim [48] and Tripura [49] states of NEI as well as than various Indian reports elsewhere from Gujarat [50] , Jammu & Kashmir [51,52] , Himachal Pradesh [16][17][18][19] , Karnataka [53] , Kerala [54] , Panjab [55] , Uttarakhand [56][57][58][59][60] and West Bengal [29,61,62] . The authors also document higher richness than the reports from Bangladesh [63,64] , Bhutan [40] and Nepal [65,66] .…”

Nitzschia taikiensis sp. nov. (Bacillariophyta) – a new brackish diatom from the Toberi River marsh in the eastern Hokkaido, Japan

“…Explanations: * -results of this study, ** -in the study of van Dam et al (1994), the data on pH requirements of Nitzschia commutata and N. commutatoides are missing. Previous reports do not exclude the possibility that these species may be alkaliphilous (Hustedt 1959a;Krammer & Lange-Bertalot 1988;Veres et al 1995;Krivograd Klemenčič et al 2007;Baruah & Kakati 2012) from N. commutata (Krammer & Lange-Bertalot 1988), however, made them similar to N. subamphioxoides. Vimines of N. taikiensis were irregularly spaced and their external openings sometimes merged with each other.…”
