The Status of Mud Crab Scylla spp. Domestication in Indonesia
摘要
Mud crabs of the genus Scylla (Scylla spp.) are a highly valuable coastal fishery commodity in Asia-Pacific countries, including Indonesia, Malaysia, Singapore, Thailand, Vietnam, India, China, Japan, and Australia. Based on electrophoresis allozyme fingerprints and mitochondrial DNA (mt-DNA) gene sequencing, Scylla consists of four species: the red mangrove crab (Scylla olivacea), also known as the “red/orange mud crab”; the green mangrove crab (Scylla serata), referred to as the “giant mud crab” due to its potential size of 2–3 kg per individual; the purple mangrove crab (Scylla tranquebarica), which can reach sizes of 0.6–1 kg per individual; and the white mud crab (Scylla paramamosain) (Keenan & Blackshaw, 1999).
