Udang air tawar merupakan hewan akuatik yang berperan penting dalam mata rantai ekosistem diperairan. Penelitian ini bertujuan untuk identifikasi dan mengkaji mengenai keanekaragaman jenis udang air tawar di Derah Aliran Sungai (DAS) Krueng Aceh, Kota Banda Aceh. Penelitian dilakukan pada bulan Juli-September 2022, meliputi tiga statiun. Penentuan lokasi sampling menggunakan metode purposive sampling, sedangkan pengambilan sampel menggunakan metode road sampling dengan melawan arus. Sampling dilakukan pada beberapa titik yang tersebar dan mewakili beberapa jenis habitat. Spesimen yang diperoleh diawetkan dalam botol yang telah diisi alkohol 70%. Pengamatan morfologi dan identifikasi spesimen dilakukan di Laboratorium Nutrisi dan Histologi Ikan, Fakultas Kelautan dan Perikanan, Universitas Syiah Kuala. Proses identifikasi dilakukan dengan meggunakan kunci identifikasi Wowor (2004). Spesimen disimpan di Laboratorium Nutrisi dan Histologi Ikan, Fakultas Kelautan dan Perikanan, Universitas Syiah Kuala. Hasil penelitian menunjukkan di DAS Krueng Aceh terdapat 6 jenis udang air tawar yang termasuk dalam family palaemonidae dan 2 jenis dari family caridae, yaitu M. lanchesteri, M. equidens, M. neglectum, M. idae, M. lanatum, M. nipponense, C. endehensis dan C. gracilirostris. Hasil tangkapan udang yang diperoleh sebanyak 376 individu, dengan indeks keanekaragaman (H’) = 1,51 (sedang), Indeks keseragaman (E) = 0,73 (sedang), dan Indeks Dominansi (C) = 0,29 (rendah). Jenis udang yang paling banyak ditemukan yaitu dari jenis C. gracilirostris berjumlah 170 individu, dan yang paling sedikit ditemukan jenis M, idae berjumlah 3 individu.

This study aims to idewntify the species and determine the diversity of freshwater shrimp in Krueng Aceh watershed, Banda Aceh City. The research conducted in July-August 2022, include at three observation site, Used purposive sampling methode. Sampling location determination uses purposive sampling method, while sampling uses road sampling method by going against the current. Sampling is carried out at several scattered points and represents several habitat types. The specimens obtained are preserved in bottles that have been filled with 70% alcohol. Morphological observations and specimen identification were carried out at the Fish Nutrition and Histology Laboratory, Faculty of Marine and Fisheries, Syiah Kuala University. The identification process is carried out using the Wowor identification key (2004). Specimens are stored in the Fish Nutrition and Histology Laboratory, Faculty of Marine and Fisheries, Syiah Kuala University.The results showed that in the Krueng Aceh watershed there were 6 species of freshwater shrimp belonging to the palaemonidae family and 2 species from the caridae family, that are M. lanchesteri, M. equidens, M. neglectum, M. idae, M. lanatum, M. nipponense, C. endehensis dan C. gracilirostris. The shrimp catches obtained were 376 individuals, with a Diversity Index (H') = 1.51 (medium), Uniformity Index (E) = 0.73 (medium), and Dominance Index (C) = 0.29 (low) . The most common type of shrimp found was from the type of C. gracilirostris totaling 170 individuals, and the least found was the type M, idae totaling 3 individuals.
