Gastropods are integral members of benthic communities, playing pivotal roles in the energy dynamics of aquatic ecosystems. This research aimed to assess changes in gastropod density influenced by seasonal variations and environmental parameters. The study was conducted during winter (pre-monsoon) and autumn (post-monsoon) periods across three areas (Khor Bahu, Khor Gowatr, and Gowatr Bay), spanning nine stations within Gowatr Wetland. Sampling of the sub-island media stations was performed using a van-veen grab. Analysis of temperature, salinity, pH, total organic matter (TOM), and granulation was conducted. Results revealed notable fluctuations in gastropod density across seasons and locations. During winter, the highest densities were observed in Khor Bahu (Pyramidellidae with 945 ± 29.15 individuals/square meter), Khor Gowatr (Marginellidae with 745 ± 36.15 individuals/square meter), and Gowatr Bay (Naticidae with 248 ± 28.14 individuals/square meter). In contrast, during autumn, peak densities were recorded in Bahu estuary (Nacellidae with 775 ± 38.45 individuals/square meter), Restusidae estuary, and Gowatr Bay (Eulimidae with 235 ± 26.12 individuals/square meter). Significant differences in density were observed among stations (p<0.05), while no significant variation was noted between seasons (p>0.05). Correlation analysis revealed a significant association between density and grain size (R=0.64), highlighting its influence on gastropod abundance. Despite the lack of significant seasonal density differences, the autumn season exhibited increased gastropod abundance, possibly attributed to the impact of southwest India's summer monsoon winds |
