This study is aimed at finding the seasonal abundance and population fluctuation of the macro-invertebrate community related to macrophytes in the Santragachi jheel lake, West Bengal, India. Here, a total of 29 species of aquatic macrophytes were recorded and then categorized into 6 groups, (1) obligatory submerged or partially submerged plants (OSPS), (2) those with aerial shoot and inflorescence stalk, (3) free floating (FF), (4) rooted floating leaved plants, rooted floating stem plants, (5) emergent (Emer) and (6) marginal (Marg). Macroinvertebrate fauna associated with macrophytes revealed a total of 69 macroinvertebrate species represented in this lake. Crustaceans, Insects and Gastropods are the most dominant groups in the jheel in terms of abundance. The mean density of total macroinvertebrate fauna associated with macrophytes was 1084.27/m2 in the Santragachi jheel lake. Oligochaeta, Ephemeroptera, Odonata, Coleoptera, Diptera had higher abundance here. Among the 11 major groups, Oligochaeta, Arachnida, Odonata, Hemiptera showed peak abundance during the monsoon period. Post-monsoon peak was observed by Hirudinea, Crustacea, Ephemeroptera, Coleoptera, Diptera, Gastropoda and Bivalvia in the jheel. The total macroinvertebrate faunal abundance has been positively influenced by macrophytal biomass especially of the OSPS type of macrophytes. Oligochaeta prefers the emergent and marginal type of macrophytes. The arachnids are positively correlated with the FF, Emer and Marg types of macrophytes. Hemiptera has a positive relationship with Emer and Marg type of macrophytes. Gastropoda exhibit a strong positive correlation with OSPS type of macrophytes. This investigation revealed that macro-invertebrates in the Santragachi jheel lake are closely related to the macrophytes there.
