“…Ikan kerapu bebek (C. altivelis) membutuhkan pakan dengan kandungan protein 54,2% untuk pertumbuhan yang baik (Giri et al, 1999). Kebutuhan protein ikan kerapu macan (E. fuscoguttatus) mencapai 48,0% (Giri et al, 2004), ikan kerapu batik (E. polyphekadion) sebesar 48% (Marzuqi et al, 2004), ikan kerapu lumpur (E. coioides) sebesar 48,0% (Suwirya et al, 2005) dan ikan kerapu sunu (P. leopardus) sebesar 48% (Marzuqi et al, 2007) untuk dapat tumbuh dengan baik. Kebutuhan protein tersebut umumnya diperoleh untuk ikan ukuran benih.…”

Sumber protein alternatif berupa protein sel tunggal (PST) dari sisa produksi bumbu penyedap dan “spent grains” dari sisa produksi minuman bir memiliki kandungan protein yang tinggi. Penelitian ini bertujuan untuk mendapatkan dosis terbaik dari penggunaan dua sumber bahan tersebut terhadap pertumbuhan dan sintasan ikan kerapu hibrid (kerapu cantik). Empat pakan uji diformulasikan dengan menambahkan kombinasi tepung spent grains dan PST untuk menggantikan protein dari tepung ikan sebesar (A) 0%, (B) 30%, (C) 40%, dan (D) 50%. Uji pakan dilakukan di keramba jaring apung menggunakan 12 jaring berukuran 2 m x 2 m x 2 m. Bobot awal ikan kerapu cantik yang digunakan adalah 63 ± 0,6 g dan ditebar dengan kepadatan 253 ekor/jaring. Pakan uji diberikan dua kali sehari secara satiasi. Data yang diamati adalah pertumbuhan (bobot dan panjang), sintasan, dan konversi pakan. Hasil penelitian menunjukkan bahwa perlakuan pakan A (0%) menghasilkan berat akhir sebesar 299,6 ± 27,0 g lebih baik dan berbeda nyata (P<0,05) dari perlakuan C (40%) dan D (50%), namun tidak berbeda nyata (P>0,05) dengan perlakuan pakan B (30%), yaitu 287,4 ± 5,3 g. Hasil ini menunjukkan bahwa substitusi protein tepung ikan dengan campuran protein dari PST dan spent grains pada pakan pembesaran kerapu hibrid dapat dilakukan sampai level 30%.Single cell protein left-over from seasoning factory and spent grains from brewery waste are potential as high protein sources for animal feed. This study was aimed to obtain an optimal supplementation dose of the two ingredients in relation to the growth and survival rate of hybrid grouper (Cantik grouper). Four test feeds were formulated by mixing different combinations of single cell protein and spent grains to replace fishmeal protein content in the feed at 0%, 30%, 40%, and 50%. The feeding trials were conducted at a floating net cage consisted of 12 netpens sized 2 m x 2 m x 2 m. The initial mean weight of hybrid grouper was 63 ± 0.6 g. The fish were stocked at a density of 253 fish/netpen. Feed treatments were given at satiation two times a day. Parameters of growth (final body weight and length), survival rate, and feed conversion were observed. The results showed that fish in treatment A (0%) gained the final body weight of 299.6 ± 27.01 g which was significantly different (P<0.05) with that of treatment C and D, but not significantly different with fish in treatment B (30%), with the mean weight gain of 287.4 ± 5,3 g. Fish in treatment B (30%) showed better growth response and survival rate than that of treatment C (40%) and D (50%). The result also indicated that fish fed with treatment B feed (30%) had not different a mean final body weight with the control feed. This study suggested that a combination of single cell protein and spent grains to substitute fish meal in grow-out feed for hybrid grouper could be applied up to 30%.

Blacksaddled coral grouper Plectropomus laevis is an export commodity and possess high economic value in Asian markets, but the wild population is already threatened. The purpose of this study was to determine the best food for improving growth and survival rate. The nursering were conducted using 9 fiberglass tanks with 1 m3 of volume for 6 month, with three treatment and 3 replicates. Three different foods were used as treatments, i.e.: Local commersial pellet with crude protein content 50% (A), im-port commersial pellet with cure protein content 55% (B) and trash fish (sardine) (C). The initial size of blacksaddled coral grouper seed were 2.5 cm total lengths (TL), 0.45 g body weight (BW). The stocking density of fry was reared at 250 fish per m3. A complete random design was used as an experiment design. Data was analysed using ANOVA statistics. Feeding times were twice a day at 08.00 and 15.00 local time; with dose at satiation. The samplings of fry were conducted every 15 day to measure of survival rate (SR), TL and BW. On the end of experiment was calculated economic ana-lized (BC ratio). The result showed that there was significant different (P<0.05) among treatments for SR and growth rate (GR). The better SR and GR was at treatment B with SR 96.5%, and GR 0.75g/day followed by treatment C (SR 90.5%: GR 0.54g/day) and treatment A (SR 81.5%: GR 0.42g/ day. The food conversion ratio was 1.15 in treatment A, 1.02 in B and 4.81 (wet weight) in C. From economic analized showed that the best BC ratio was in pellet 55% protein (B), followed by trash fish (C) and pellet 50% protein (A) with BC ratio of 1.75, 1.72 and 1.41 respectively.

“…Pemberian pakan buatan dalam bentuk pelet dapat diaplikasikan untuk budidaya ikan kerapu karena menunjukkan pertumbuhan dan efisiensi pakan yang baik serta tidak menunjukkan gejala kekurangan nutrien. Selain itu pakan buatan dapat disimpan dalam jangka waktu yang panjang (Suwirya et al, 2005). Pakan diperlukan untuk pertumbuhan, kesehatan ikan dan untuk peningkatan mutu produksi.…”

“…Kandungan nutrisi dalam pakan berkaitan erat dengan konsumsi/asupan pakan pada ikan. Menurut Suwirya et al (2005), nutrisi dalam pakan akan mempengaruhi asupan pakan pada ikan yang diberi makan secara ad libitum.

“…Sih-Yang Sim et al (2005) menyatakan bahwa nilai rasio konversi pakan pelet untuk ikan kerapu adalah 1,67, sementara untuk FCR pakan rucah adalah 6,0. Pemberian pakan buatan dan ikan rucah pada ikan kerapu bebek selama 4 bulan pemeliharaan menghasilkan nilai rasio konversi pakan masingmasing 1,54 dan 5,82 (Suwirya et al, 2005).…”
