Aim: The fisheries resources of Mandovi Estuary, along the central west coast of India were analysed for taxonomic, functional, feeding and population aspects and also to record and prepare an inventory on fish and shellfish species. Methodology: Finfish and shellfish taxa were monitored for four years (2016 to 2020) through surveys in small and regional markets, fishermen surveys, fishing gear samplings, telephonic interviews and photographs. Results: A total of 318 taxa are counted comprising of 169 (53.1%) demersal, 71 (22.3%) pelagic fish, 37 (11.6%), molluscan and 41 (12.9%) crustacean species. The community was dominated by marine immigrants and the freshwater types contributed least to the composition. In the inventory, majority of the resources were of commercial value and this category contributed 70% of total documented species. Even though detailed analyses were required, nearly 2% of the fauna appeared to be endemic to the region. Further, more than 30% species listed were data deficient. Out of 318 species, 10% were unknown in the Mandovi estuary. Interpretation: This data set comprehensively documents the finfish and shellfish diversity of Mandovi estuary from 2016 to 2020. The type of fish assemblage is briefly discussed focusing on the management of these resources in the estuary.
