Seasonal Effects of Physicochemical Parameters on Fish diversity, Population Dynamics, Species Index, and IUCN Status in the Kalpakkam Coastal Waters, Bay of Bengal, India
Oceanography & Fisheries Open Access Journal Juniper publishers Authored by: Kantha Deivi Arunachalama Abstract Seasonal variations in physicochemical parameters and fish diversity, population dynamics, species index, and IUSN status were investigated in this study; quantitative samples were collected monthly from January 2019 to December 2020 around the Kalpakkam coastal water in the Bay of Bengal (BOB). Water and sediment parameters are compared to fish diversity. The Zoological Survey of India confirmed the existence of 102 fish species collected along the coast, divided into two groups, 22 orders, and 56 families. Fish diversity was calculated in five villages using the species index, species richness, and Shannon-Weiner index, with Sadras kuppam having the highest and Mahabalipuram beach having the lowest. When the collected fish species were compared to the International Union for Conservation of Nature (IUCN) threatened lists, 46.08 % were determin...
