- Abstract
Bivalves are ubiquitous in all habitats, including marine and freshwater environments. The present paper revises bivalve diversity and their current status along the two selected sites of the Sikka coast, i.e., the Vador site and the GSFC jetty site. The selected study site, the Sikka coast, lies at the centre of the southern coast of the Gulf of Kachchh, Jamnagar, Gujarat, India under the jurisdiction of Marine National Park, Forest Department, Jamnagar. During the study, samples were recorded during low tide hours followed by a tide chart for a period of six regularly scheduled months, from December 2021 to May 2022. The voucher specimens were collected for each species. The collected samples were identified up to species level with the help of different reference books. During the entire study, 15 bivalve species belonging to 7 orders, 11 families and 15 genera were recorded from two sites. Brachidontes undulatus and Saccostrea cucullata were the densest and abundant species throughout the study period at both sites whereas Pinna bicolor and Pinctada fucata were most frequently recorded throughout the study. Mean Shannon diversity index (H') values for bivalve for the entire study period at GSFC (1.603) were comparatively higher than at Vador (1.421). Station-wise, mean Margalef's richness index was higher at GSFC (2.185) than Vador (1.917). The mean evenness value at the Vador was 0.3672, while the GSFC value was 0.4282.
