The purpose of the study was to determine the sustainability status of Stingray capture to determine the feasibility of catching Stingray in the waters of West Manggarai Regency. The research method used is the survey method, and this was conducted in July 2018 until mid-September 2018. The parameters studied included the type of Stingray, size and sex ratio. The results showed that the Stingray species found were A. narinari, D. kuhlii, H. granulata, H. uarnak, P. sephen, and T. lymma, with species diversity still stable (H' = 1,4). The average size of Stingray species caught makes it, however, not worth catching. Comparison of the Stingray sex ratio shows that T. lymma and H. granulata species were unbalanced, thus they should not be caught. D. kuhli and H. uarnak are still in balance so they can still be harvested. Based on conservation status in IUCN, the stingray that had the most severe threat status was H. granulata and H. uarnak, thus, these should not be harvested at all.
