PENGARUH PERBEDAAN WARNA WADAH TERHADAP SINTASAN DAN PERTUMBUHAN LARVA IKAN BAUNG (Hemibagrus nemurus Blkr)

Abstract

Penelitian warna wadah dilakukan untuk mengetahui pengaruhnya terhadap sintasan dan pertumbuhan larva ikan Baung (Hemibagrus nemurus Blkr.). Penelitian dilakukan di Instalasi Riset Lingkungan Perikanan Budidaya dan Toksikologi Cibalagung, Bogor. Wadah yang digunakan berupa 24 unit akuarium berukuran 70 cm x 40 cm x 45 cm yang diisi air sebanyak 40 L dan dilengkapi aerasi sistem sikulasi air. Hewan uji yang digunakan adalah larva ikan baung umur 1 hari yang ditebar dengan kepadatan10 ekor/L dan diberi pakan alami, yaitu artemia (ad libitum) dan dilanjutkan dengan cacing sutra (at satiation). Perlakuan berupa perbedaan warna wadah, yaitu: kontrol, merah kuning, dan biru. Waktu penelitian selama 21 hari. Hasil penelitian menunjukkan warna wadah tidak berpengaruh terhadap sintasan (18,96%; 19,12%; 18,18%; 10,50%) maupun pertumbuhan.

The main purpose of this experiment was know the effect of tank colour differences on survival and growth of catfish(Hemibagrus nemurus Blkr) larvae .
