ABSTRACT

Potential soft-shalled turtle (Amyda cartilaginea) in the region Bali are still quite plentiful, which was captured as many as 108 soft-shalled turtles with very high variations in size from the size of the biomass weight of 80 grams to the jumbo size with 21,400 grams (21.4 kg) of weight. There were caught 23 biomass in Denpasar ranging from 175-5,800 grams with carapace length ranging from 11.4- 38.0 cm, and carapace width ranged from 9.1 to 31.0 cm. There were caught 27 biomass in Badung ranging from 85-3,900 grams. Morphometric measurement includes total carapace length ranged from 9.4 to 34.2 cm and total carapace width ranged from 7.8 to 28.0 cm. There were caught 21 biomass in Gianyar District weighed 125-5,750 grams. There were caught 21 biomass in Tabanan District weighed 200-21,400 grams. Morphometric measurement of soft-shalled turtle includes total carapace length 11.1-60.3 cm and carapace width 9.6-46.0 cm, with a negative allometric growth model for relations between total carapace length with weight and between carapace width and weight. There were caught 16 biomass in Klungkung ranging from 140-4,250 grams. Morphometric description includes carapace length (PC) ranged from 10.5- 37.8 cm, carapace width (LC) ranged from 8.4 to 30.6 cm, plastron length (PP) ranged from 7.4 to 27.3 cm, plastron width (LP) between 9.3 to 31.2 cm and total length of ventral (PTV) between 11.4 to 39.0 cm. Distribution (dispersion) of soft-shalled turtle (Amyda cartilaginea) resource is uneven on some fishing ground. GIS analysis result showed that centralization happened only on some areas, especially in Klungkung District, soft-shalled turtles were dominantly caught in the upstream of Tukad/Yeh Jinah river (Selisihan, Mangduang, Aan and Penasan), and In Denpasar, it was concentrated in the area of Kedue, Penatih, Muding Padang Sambian and Medui area
