Description The aim of this study was to understand the ecohydrological interactions of periphyton assemblages in a canal (Bishalakhi) located in the Indian Sundarban. Sixteen environmental variables and periphyton (scrapped from a known area of submerged natural substrates) were collected seasonally (pre-monsoon, monsoon, and post-monsoon) from three sampling stations between July 2017 and September 2018. Data was analyzed to determine periphyton diversity, abundance, spatiotemporal dynamics, and their relationship with environmental variables using R-software. Eleven environmental variables (water temperature, water depth, water velocity, specific conductivity, total alkalinity, salinity, Mg2+, PO4−P, TP, SiO4−Si, and transparency) showed significant difference (p CCA2 (0.93) > CCA3 (0.93). The majority of the diatom (36 species) had a strong affinity with dissolved oxygen and total nitrogen. The water velocity and specific conductivity were found to influence the distribution of species (Phormidium sp., Ankistrodesmus falcatus, Diploneis sp., Synedra sp., Eunotia sp., and Nitzschia recta) in the canal environment. The results of this study advance the current understanding of the relationship between periphyton and its environment and may aid for better planning of periphyton-based aquaculture in the semilotic canals of Indian Sundarbans.
