PERTUMBUHAN IKAN PATIN SIAM (Pangasianodon hypopthalmus) YANG DIPELIHARA DENGAN SISTEM BIOFLOK PADA Feeding Rate YANG BERBEDA
Abstract
Ikan patin membutuhkan pakan dengan kandungan protein 28-30%, dan Feeding rate berkisar antara 2–5% perhari. Namun keseluhuran pakan yang diberikan hanya 25% dikonversi sebagai biomasa dan sisanya terbuang sebagai limbah (amoniak dan feses). Hal ini mengakibatkan penurunan kualitas air sehingga pertumbuhan ikan terganggu. Bioflok salah satu alternatif mengatasi masalah kualitas air. Dengan memanfaatkan kemampuan bakteri heterotrof untuk memanfaatkan limbah dalam air budidaya diubah menjadi pakan alami tambahan yang bermanfaat sebagai sumber energi dan meningkatkan pertumbuhan ikan. Perbedaan jumlah pakan yang diberikan diduga mengakibatkan perbedaan jumlah kepadatan bioflok dalam suatu perairan. Penelitian ini bertujuan untuk mengetahui pengaruh Feeding Rate yang berbeda terhadap pertumbuhan ikan patin siam yang dipelihara dalam sistem bioflok. Rancangan penelitian yang digunakan adalah rancangan acak lengkap dengan empat perlakuan dan tiga kali ulangan. Perlakuan berupa pemberian pakan dengan FR yang berbeda (1%, 3%, 5%, 5% + non bioflok). Hasil penelitian menunjukkan bahwa pemberian FR yang berbeda berpengaruh terhadap pertumbuhan ikanpatin siam. Pertumbuhan ikan tertinggi ditunjukkan pada pemeliharaan dengan menggunakan sistem bioflok pada FR 5% dan pertumbuhan ikan terendah diperolehDownloads
