Abstract

Udang air tawar spesies Macrobrachium scabriculum (Heller, 1862) untuk pertama kalinya dilaporkan dari Sulawesi, Indonesia. Spesies ini dideskripsi pertama kali berdasarkan spesimen yang ditemukan di Sri Lanka. Penyebarannya di Indonesia, sebelumnya dilaporkan dari Sumatera dan Kalimantan. Dalam artikel ini, deskripsi dan ilustrasi M. scabriculum didasarkan pada spesimen yang dikoleksi pada Mei 2016 dan November 2017 di Sungai Batusuya, Donggala, Sulawesi Tengah. Dalam laporan ini juga disajikan sistematika, karakter morfologi, habitat dan distribusi dari udang jenis ini.

Abstract

Sistem Danau Poso terletak di Pulau Sulawesi, Indonesia yang memiliki kekayaan berbagai spesies endemik, termasuk udang air tawar genus Caridina. Penelitian ini bertujuan untuk mengidentifikasi dan mendeskripsi udang air tawar dari Sungai Pomua Palandu, Poso, Sulawesi, Indonesia. Sampling dilakukan pada beberapa titik yang tersebar pada bagian hulu hingga hilir sungai menggunakan metode purposive sampling. Spesimen yang diperoleh diawetkan dalam botol yang telah diisi alkohol 96% dan disimpan sebagai koleksi laboratorium. Pengamatan morfologi dan identifikasi spesimen dilakukan di Laboratorium Biodiversitas, Jurusan Biologi FMIPA Universitas Tadulako. Dari hasil penelitian diperoleh satu spesies udang air tawar genus Caridina yaitu Caridina cf. sarasinorum yang secara morfologi mirip dengan Caridina sarasinorum yang dideskripsikan kembali oleh von Rintelen dan Cai (2007)

Abstract

Sulawesi is one of the four Greater Sunda Islands characterized by rivers and lakes habitats of freshwater shrimps and prawns with a high degree of endemism. The freshwater shrimp and prawns diversity in the Batusuya river of Donggala is less studied compared to the ancient lakes in the Central Sulawesi area. This study aimed to determine the diversity of freshwater shrimp and prawns of the Batusuya river. The sample was collected in November 2016 using tray net. The study site divided into three sampling stations based on the type of habitat. Nine species of freshwater shrimps and prawns were found, i.e., Macrobrachium australe, M. esculentum, M. horstii, M. lar, M. placidulum, Caridina brevicarpalis, C. gracilipes, C. weberi, and Atyopsis spinipes. Six species were found in all localities including Macrobrachium australe, M. esculentum, M. horstii, M. lar, C. brevicarpalis, and C. gracilipes, while M. placidulum, C. weberi, and A. spinipes were not found in all stations. The highest diversity index (H') was found in the station III indicated freshwater shrimps and prawns favored the environmental conditions of this station. The highest measure of species richness (R) was found in the station I and presumably related to the life cycle of freshwater shrimps and prawns which is amphidromous. The occurrence of nine species of freshwater shrimps and prawns along the Batusuya river indicated the environmental condition of the stream was suitable for most freshwater shrimps and prawns, and the Macrobrachium australe was found as the most abundant species.
