LiufetoFaculty of Animal Husbandry, Marine and Fishery, Universitas Nusa Cendana, Indonesia*Corresponding author: yudiana@staf.undana.ac.idAbstractThe waters of Kupang Bay serve as important fishing grounds for both finfish and crustaceans. Although the area is a major centre for fishing in Indonesia, it still holds significant untapped potential for economically valuable marine biota. Crustacean fishing is typically carried out alongside finfish fishing by local fishermen. This study aims to map and analyse the characteristics of crustacean fishing locations based on the fishing activities of local fishers. The targeted crustaceans include species caught in trawl or gill nets, regardless of whether they are commonly consumed. Fishing locations were determined using GPS (Geographic Information System) tools and based on information provided by local fishermen. Mapping and characterizing these fishing sites help identify their specific locations, physical and chemical parameters, substrate types, and fishing seasons. This information is essential for promoting environmentally friendly and sustainable fishing practices. Furthermore, understanding the water and substrate characteristics serves as a reference for future crustacean aquaculture initiatives in Kupang Bay. The results of the study indicate that the main crustaceans caught include mangrove crabs, swimming crabs, mantis shrimp, turtle crabs, white shrimp, tiger shrimp (black shrimp), and red shrimp. These findings highlight the richness of crustacean resources in Kupang Bay. However, current utilization remains limited, with individual catches ranging from only 1 to 25 kilograms per fisherman.Keywords: mapping, bay, Kupang, shrimp, crab, swimming crab
