ABSTRACT

The present study was carried out to collect, identify, and describe the fish diversity, verified using diversity indices and the conservation status (IUCN) of the finfishes and shellfishes landed at Dholai port, Bilimora, Gujarat (India) from July 2022 to April 2023. A total of 45 landed fish species was recorded, belonging to 20 orders, 29 families, and 40 genera. The findings showed that Class Actinopterygii (55%) was dominated. The main objective of the present study was to collect, identify, and describe the fish diversity verified using diversity indices and conservation status (IUCN) of the finfishes and shellfishes landed at Dholai Port, Bilimora, Gujarat (India), for a period from July 2022 to April 2023. A total of 45 landed fish species belonged to 20 orders, 29 families, and 40 genera. The findings depicted that Class Actinopterygii (55%) was dominant, followed by Chondrichthyes (20%), Cephalopoda (15%), and Malacostraca (10%). Among the 45 species, diversity indices were calculated Shannon–Wiener index (H) -1.102, Margalef Index (D) -0.7881, Evenness index (E) -0.524, and conservation status of IUCN categorized as Least Concern (46%), Near Threatened (7%), Vulnerable (7%), Not Evaluated (20%), Endangered (7%), Data Deficient (9%), and Threatened (4%), respectively. The study revealed that biodiversity indices indicate a moderate level of biodiversity within the ecosystem. The presence of threatened species demands the need for conservation efforts and implementation of sustainable management practices.
