Description ABSTRACT This study aims to determine the types of fish in Lubuk Soda Jorong Mudiak Aia Nagari Tambangan X Koto District, Tanah Datar Regency. The time of the research was carried out in March 2021. The fishing gear needed in this study were: tangguk, nets, fishing rods. In addition, the materials needed are: fish samples,  , , NaOH-KI,  , starch and 70% alcohol. Fishing is carried out at 07.00-18.00 WIB. The sampling location was determined by dividing 3 stations based on different substrate conditions. Station 1 at Lubuk Limau spring which has small rocks and clear and cold water, Station 2 at Kapalo Banda water has rock substrates plastered with moss and clear water characteristics, Station 3 has algae on the rocks, clear, shallow water. This research uses purposive sampling method. The measured water physicochemical factors were temperature, pH, DO, and current velocity. This research uses purposive sampling method. The results of the research that have been carried out are obtained as many as belonging to 4 orders, 7 families, 10 genera and 12 species  namely: (Tor tambra), (Punctius binotatus), (Rasbora sumatrana), (Rasbora rutteni), (Nemacheilus pfeifferae), (Homaloptera heterolepis), (Xiphophorus maculatus), (Xiphophorus helleri), (Oreochromis niloticus), (Macrognathus maculatus). The most common type of fish found was Tor tambra as much as 16.12% and the least fish species found were Macrognathus maculatus and Homaloptera heterolepis which were only found 3.22% of the total number of fish obtained. The results of the measurement of environmental physicochemical factors, the average air temperature is 23ºC, the average pH is 7.7, the average flow velocity is 5.12 m/s and the DO average is 4.83 mg/L.   Keywords: river, fish, environmental physicochemical factors ABSTRAK Penelitian ini bertujuan untuk mengetahui jenis-jenis ikan dan faktor fisika kimia yang meliputi suhu, pH, DO, dan Kecepatan Arus di Lubuk Soda Jorong Mudiak Aia Nagari Tambangan Kecamatan X Koto Kabupaten Tanah Datar. Penelitian ini dilaksanakan pada bulan Maret 2021. Alat tangkap yang dipakai dalam penelitian ini adalah: tangguk, jala, pancingan. Selain itu bahan yang diperlukan yakni : sampel ikan,  , , NaOH-KI,  , amilum dan  alkohol 70%. Penangkapan ikan dilakukan pada pukul 07.00-18.00 WIB. Lokasi pengambilan sampel ditentukan dengan membagi 3 Stasiun berdasarkan kondisi substrat yang berbeda-beda. Stasiun 1 di mata air Lubuk Limau yang terdapat bebatuan kecil dan berair jernih serta dingin, Stasiun 2 di air Kapalo Banda terdapat substrat bebatuan yang ditempeli lumut serta karakteristik perairan yang jernih, Stasiun 3 terdapat alga di bebatuan, perairan jernih, dangkal. Penelitian ini memakai metode purposive sampling. Hasil penelitian yang telah dilakukan diperoleh sebanyak 4 Ordo, 7 Familia, 10 Genus dan 12 Spesies yakni : (Tor tambra), (Punctius binotatus), (Rasbora sumatrana), (Rasbora rutteni), (Nemacheilus pfeifferae), (Homaloptera heterolepis), (Xiphophorus maculatus), (Xiphophorus helleri), (Oreochromis niloticus), (Macrognathus maculatus). Jenis individu yang paling banyak ditemukan yaitu Tor tambra sebanyak 16,12 % dan jenis individu yang paling sedikit ditemukan yaitu Macrognathus maculatus dan Homaloptera heterolepis yang pada masing-masing ditemukan 3,22% dari jumlah total ikan yang didapatkan. Hasil pengukuran faktor fisika kimia lingkungan rata-rata suhu udara yaitu 23ºC, rata-rata pH 7,7, rata-rata kecepatan Kecepatan Arus 5,12 m/s dan rata-rata DO yaitu 4,83 mg/L.   Kata kunci : sungai, ikan, faktor fisika kimia lingkungan
