Abstract: Fish biodiversity in the mangrove area of Lombok, West Nusa Tenggara, Indonesia, seems to be forgotten, even though Lombok is the gateway to the Wallacea region. The purpose of this study was to determine the biodiversity and status of mangrove fish species in Lombok. The study was conducted in North Lombok and East Lombok using gillnets with 1-inch, 1.5-inch, and 2-inch meshes and stocking net diameters of 1.5 cm and 2 cm. The results obtained were 79 species of fish belonging to 41 tribes and 69 genera. The dominant species were Planiliza subviridis (13.17%), Sardinella lemuru (12.44%), and Sillago sihama (11.70%). The value of the index (H) ranges from 2.542 to 3.356, the value of species richness (d) ranges from 3.531 to 8.582, and the value of species evenness (E) ranges from 0.832 to 0.917. Sardinella lemuru and Rastrelliger faughni, both near-threatened species, were recorded in this study. The study was expected to provide information on the species richness and status of fish in mangrove areas in Lombok, which can be used to determine policy strategies for the management and sustainable use of fish in this area.
