      Abstract
      Ikan semah Tor douronensis merupakan jenis ikan asli yang menghuni perairan tawar Indonesia. Populasi ikan tor di alam tergolong langka. Induk yang digunakan berasal dari daerah Sumatera. Jumlah induk Ikan semah yang ada dikolam berjumlah 150 ekor. Pemeliharaan induk ikan semah dilakukan pada kolam berbentuk persegi panjang yang memiliki ukuran 8 m x 4 m x 0,7 m dengan dasar kolam berbatu koral. Pemijahan ikan semah yang dilakukan yaitu menggunakan teknik semi buatan. Perbandingan induk ikan semah yang digunakan yaitu 1:2 yang artinya 1 betina dengan 2 jantan. Fekunditas 2,604 butir, rata-rata fertilization rate 91,5%, hatching rate 91,6%, survival rate 91%, pertumbuhan panjang 0,75 cm, pertumbuhan berat 0,0277 g, Suhu kolam induk dan akuarium sebesar 24–28oC, pH 7,02–7,86, dan DO 5,2–6,1 mg/L. Kegiatan pembenihan ikan semah di Instalasi Plasma Nutfah Perikanan Air Tawar Cijeruk meliputi pemeliharaan induk, seleksi induk, pemijahan, penetasan telur, dan pemeliharaan larva. Pembenihan ikan semah dapat dikatakan baik sesuai dengan hasil yang didapatkan dari pengukuran kualitas air, kualitas benih serta penerapan inovasi yang diberikan dilaksanakan dengan baik dalam jangka panjang.
       
      Tor douronensis is a native fish species that inhabits Indonesia's fresh waters. The Tor fish population in nature is relatively rare. The broodstock used comes from the Sumatra region. The number of semah fish broodstock in the pond amounted to 150 fish. Semah fish broodstock rearing is carried out in a rectangular pond that has a size of 8 m x 4 m x 0.7 m with a coral bottom.. Semah fish spawning is carried out using semi-artificial techniques. The ratio of semah fish broodstock used is 1: 2, which means 1 female with 2 males. Fecundity was 2,604 eggs, average fertilization rate 91.5%, hatching rate 91.6%, survival rate 91%, length growth 0.75 cm, weight growth 0.0277 g, semah fish brood pond temperature of and while the aquarium temperature was 24-28oC, pH 7.02-7.86, and DO 5.2-6.1 mg/L. Semah fish hatchery activities at the Cijeruk Freshwater Fisheries Germplasm Installation include broodstock rearing, broodstock selection, spawning, egg hatching, and larval rearing. Semah fish hatcheries can be said to be good according to the results obtained from measuring water quality, seed quality and the application of innovations provided is well implemented in the long term.
