Penelitian ini bertujuan untuk mengetahui pengaruh penambahan tepung silase jeroan tuna dalam pakan terhadap laju sintasan dan pertumbuhan lele dumbo (Clarias sp.). Penelitian dilakukan secara eksperimen menggunakan Rancangan Acak Lengkap (RAL) dengan enam perlakuan dan tiga ulangan. Perlakuan meliputi P1 (100 % TI); P2 (75 % TI : 25 % TSI); P3 (50 % TI : 50 % TSI); P4 (25 % TI : 75 % TSI); P5 (100 % TSI); P6 (Pakan ikan komersial). Kandungan protein pakan uji berkisar 27,77 – 33,94 %. Penelitian dilakukan selama 60 hari dengan menggunakan bak fiber ukuran 50 x 50 x 60 cm³ dengan kepadatan 30 ekor/bak. Pemberian pakan sejumlah 7 % dari biomassa dengan frekuensi sebanyak dua kali sehari. Hasil penelitian menunjukkan bahwa laju sintasan tertinggi dihasilkan pada perlakuan penambahan tepung silase jeroan tuna sebesar 75 %. Pertumbuhan tertinggi dihasilkan oleh perlakuan tanpa penambahan silase jeroan tuna.

This study aimed to determine the effect of addition tuna viscera silage meal in diets on survival and growth rate of the catfish (Clarias sp.) The experiment used Completely Randomized Design (CRD) with six treatments in triplicate. The composition were, P1 (100% TI); P2 (75% of IT: 25% TSI); P3 (50% of IT: 50% TSI); P4 (25% of IT: 75% TSI); P5 (100% TSI); P6 (commercial fish feed). The protein content for daily diets was 27,77 – 33,94%. The study was conducted for 60 days by using fiber tub measuring 50 x 50 x 60 cm³ with a density of 30 fish / tub. Feed was given twice a day from 7% of the biomass. The results showed that highest survival rate in the study was produced by treatments with the addition tuna viscera silage meal by 75 %. The highest growth in the study was produced by feed without addition tuna viscera silage meal.
