Molecular identification and potency of scalloped spiny lobster (Panulirus homarus) study from Kodang Merak Beach, South Malang

Abstract

Abstract Lobster is one of the commodities from the fisheries sector that has high economic value. The problem faced is that there is still limited biological information on lobster species in Indonesia, including identifying genetic diversity. The purpose of this study was to determine the potential ofscalloped spiny lobster. Lobster identification was carried out morphologically and molecularly on the most dominant lobster species at Kondang Merak Beach, Malang. The method in this study used observation and experimental methods. The results of recording data on natural lobster catch from local fishermen from Kondang Merak,scalloped spiny lobster is the most dominant species compared to other types of lobster (painted spiny lobster, ornate spiny lobster). Morphologically, the most dominant lobster sample (MAL-01) obtained from this research location was Panulirus homarus. The lobster has a color pattern and meristic characteristics that are in accordance with the morphological identification reference used. Molecular identification of scalloped spiny lobster (DNA barcoding) has shown that the lobster specimen is a scalloped spiny lobster (Panulirus homarus) which has the same sequence as KF548574 (100%) in the BLASTN results with the Genbank Database.
