Description Increased commercial feed African catfish (Clarias gariepinus) are not dimbangi with an increase in sales price of production, so as necessary to find a cheap alternative feed and nutrients according to the needs of African catfish. Offal shark (Rhizoprionodon sp.) Can be used as alternative feed with fermented silage first being to improve the quality of its nutritional value. This study aims to determine the effect and dose utilization of sharks in offal silage feed formula to the growth of African catfish (Clarias gariepinus.). The experimental design used was completely randomized design (CRD) with 5 treatments and 3 replications that substitution treatment offal silage protein sharks against fish meal protein. The results showed the best dose offal silage sharks to substitute protein fish meal in fish feed formulas African catfish is amounted at 63.50% for the specific growth rate of 5.004% of body weight / day; 63.50% for feed conversion ratio of 1.21; 41.67% for protein efficiency ratio 0.049; 57.93% to 25.40% protein retention and 52.00% for the activity of the protease enzyme tyrosine 12.31 mol / g.menit.
Peningkatan pakan komersil  ikan lele dumbo (Clarias gariepinus) tidak dimbangi dengan peningkatan harga jual produksinya, sehinggga perlu dicarikan pakan alternatif yang murah dan mengandung nutrisi yang sesuai kebutuhan ikan lele dumbo. Jeroan ikan hiu (Rhizoprionodon sp.) bisa dijadikan pakan alternatif dengan difermentasi terlebih dahulu menjadi silase  untuk meningkatkan kualitas nilai gizinya. Penelitian ini bertujuan untuk mengetahui Pengaruh dan dosis pemanfaatan silase jeroan ikan hiu dalam formula pakan terhadap pertumbuhan ikan lele dumbo (Clarias gariepinus.). Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 3 ulangan yakni perlakuan subtitusi protein silase jeroan ikan hiu terhadap protein tepung ikan. Hasil penelitian menunjukkan dosis terbaik silase jeroan ikan hiu  untuk mensubstitusi protein tepung ikan dalam formula pakan ikan lele dumbo adalah sebesar sebesar 63,50% untuk laju pertumbuhan spesifik 5,004 %BB/hari; 63,50% untuk rasio konversi pakan 1,21; 41,67% untuk rasio efisiensi protein 0,049; 57,93% untuk retensi protein 25,40% dan 52,00% untuk aktivitas enzim protease 12,31 µmol tirosin/g.menit.
