Abstract

Several rivers flow across Daerah Istimewa Yogyakarta (DIY includes Opak River which it’s upstream located on Merapi Volcano area. The river has a lot of biological resources, includes prawns. Freshwater prawns (Macrobrachium spp.) has important role in maintaining the balance of freshwater ecosystems. The purpose of this research was to determine species diversity of Macrobrachium spp. and to understand the morphological and molecular characters of them. Phenetic similarity was analyzed using 74 morphological characters, ISSR1 and ISSR3 primers. The results were analyzed using a program MVSP 3.1 (Multi- Variate Statistical Package) to obtain a dendogram that showed both intra-and interspecies similarity of Macrobrachium spp. Six species of Genus Macrobrachium were identified, they are Macrobrachium pilimanus, M. sintangense, M. lanchesteri, M. cowlesi, M. latidactylus, and M. equidens. Both morphological and molecular analyses show two major clusters with the similarity of 55.6% for morphology and 21.52% for molecular. Based on morphological and molecular characters analysis, we concluded that phenetic similarity of Macrobrachium spp. in Opak River was affected by the morphological structure of the second pereiopod, habitat type, size and number of eggs, as well as the type of larval development.Keywords: characters, Macrobrachium, molecular, morphology, Opak River

Abstract

Crabs has been known inhabiting diverse habitat. Crabs were found in the sea, and some other species were found in terrestrial or freshwater. Crabs is one of the important biotic components of the aquatic ecosystem as detrivore. Opak River is one of the major rivers in the Daerah Istimewa Yogyakarta (DIY), which has a various conditions and direct impact on biodiversity including the diversity of crabs. Up to now, there is no database of crab species from Yogyakarta. The aim of this research was to determine the diversity of crabs from Opak River. Research were carried out for 5 months between June and October 2013. Samples were characterized and identified morphologically. The results show that there are five species of crabs in Opak River. Parathelphusa convexa (De Man, 1879) was commonly found from upstream to downstream. Varuna litterata (Fabricius, 1798) was found in downstream to estuary (brackish water). The other three species were only found in the estuary area viz. Ocypode ceratophthalma (Pallas, 1772), Episesarma versicolor (Tweedie, 1940), and Scylla serrata (Forsskål, 1775). It can be concluded that diversity of crabs in the Opak River estuary area is higher than the upstream and downstream areas.Keywords: brachyuran, crabs, diversity, morphology, Opak River
