Abstract
Abstrak Ikan Patin (Pangasius sp.) hidup secara alami di sungai dan memiliki ciri berkulit halus. Pemeliharaan ikan Patin dengan padat tebar yang cukup tinggi membutuhkan sistem pemeliharaan khusus, seperti sistem berarus. Penelitian ini mempelajari pengaruh arus terhadap kinerja pertumbuhan dan kelangsungan hidup ikan Patin Pasupati yang merupakan hasil persilangan antara ikan Patin Siam dengan ikan Patin Jambal. Penelitian dilakukan selama 93 hari (November 2018-Februari 2019) di Laboratorium Akuatik, Pusat Penelitian Limnologi LIPI menggunakan bak fiberglas persegi panjang bervolume 875 L yang dilengkapi dengan sistem resirkulasi. Variasi kecepatan arus yang digunakan yaitu A (0 m/s), B (0,2 m/s), dan C (0,4 m/s). Ikan Patin yang diteliti berukuran panjang dan berat awal 13,64 ± 1,26 (12-14) cm dan 24,41 ± 3,87 (22,07-29.19) g dengan kepadatan awal 40 ekor/bak. Analisis data yang dilakukan secara deskriptif memperlihatkan bahwa perlakuan C memberikan hasil tertinggi pada 90% parameter pertumbuhan ikan yang diamati, yaitu panjang akhir 31,17 ± 0,78 cm, berat akhir 295,72 ± 43,02 g, pertambahan panjang 17,53 ± 0,78 cm, pertambahan berat 271,31 ± 43,02 g, pertumbuhan spesifik (SGR) panjang 0,89 ± 0,03% dan SGR berat 2,68 ± 0,15%, pertumbuhan panjang 0,19 ± 0,01 cm/hari, pertumbuhan berat 2,92 ± 0.46 g/hari, dan kelangsungan hidup (SR) 87,98 ± 10,84%.
