Abstract

This study aims to inventory the types of fish caught in the waters of Kaiely Bay using the stationary lift-net (gillnet barrier). The research method consisted of direct field observations and interviews with fishermen who own and operate the gillnet barrier. The catch data were analyzed to determine the composition of fish species, feeding habits, and habitat characteristics. The results showed that the catches consisted of both demersal and pelagic fish with varying proportions. The percentage of pelagic fish was 18%, demersal fish 11%, obligate resident species 61%, opportunistic species 22%, and temporal species 16%. Species diversity also showed significant variation, particularly among three dominant fish families: Perciformes (samandar), Scombridae (mackerel), and Clupeidae (anchovy), all of which recorded diversity index (H’) values greater than 2. This indicates that these three fish families play an important role in the Kaiely Bay ecosystem. The dominance index (C) for the three families ranged between 0.006–0.032, higher than other species that showed values below 0.006. Similarly, the species richness index (D) for these three families reached 89.2, indicating a higher abundance and dominance compared to other fish species caught in the bay. These findings highlight that the gillnet barrier in Kaiely Bay does not only capture pelagic and demersal fish but also reflects the ecological dynamics of the waters, including the presence of opportunistic and temporal species. This information is expected to serve as a basis for sustainable fishery resource management in the Kaiely Bay area.
