Abstract


Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pakan alami dan pakan  buatan terhadap laju pertumbuhan spesifik, laju pertumbuhan panjang harian dan laju konsumsi pakan harian ikan Betutu (Oxyeleitris marmorata). Penelitian ini dilakukan dengan memelihara ikan betutu dalam akuarium berkapasitas 20 L menggunakan 4 perlakuan pemberian pakan yaitu cacing sutra (Tubifex sp.), cacing darah (larva Chironomus sp.), ikan mas (Cyprinus carpio) dan pakan buatan pelet selama 28 hari. Pengukuran berat dan panjang dilakukan setiap 7 hari. Hasil Anova one-way menunjukkan bahwa pemberian pakan alami cacing sutra (Tubifex sp.), cacing darah (larva Chironomus sp.), ikan mas (Cyprinus carpio) dan pakan buatan pelet berpengaruh terhadap laju pertumbuhan spesifik, laju pertumbuhan panjang harian dan laju konsumsi pakan harian ikan betutu (Oxyeleotris marmorata). Perlakuan pemberian pakan alami cacing sutra (Tubifex sp.) memperlihatkan laju pertumbuhan spesifik, laju pertumbuhan panjang harian, dan laju konsumsi pakan harian yang tinggi, yaitu sebesar 1,595%, 0,271% dan 6,923% dibandingkan dengan perlakuan pemberian pakan buatan pelet yaitu 0,505%, 0,139% dan 5,304%
