Abstract
Species Dominance of molluscs was studied from January 2020 to December
2021 on the basis of the prevalence of muddy and rocky substratum, a single
station, Gopnath was chosen and subdivided into three sites (Site-A, Site-B and
Site-C). On a monthly basis, 30 Quadrates (1m x 1m) were applied at random to
each location. There is a total of 61 species of molluscs, distributed across
23 families. 21 families of molluscs were shared by all 3 sub sites. However,
site-A had a greater diversity (H’=2.756), evenly distributed (0.6845) and rich
(5.352) of molluscs. Site-A (D=0.9105), Site-B (D=0.8998) and Site-C (D=0.888)
all showed greater number of dominant species, indicating that there is an
approximate 90% chance of obtaining a distinct species with each random
sampling attempt. In contrast, Cerithidae emerged as the dominant and most
abundant gastropod family along the littoral of Gopnath followed by Trochidae.
