“…Among these parameters, only fat content was significantly different between feed treatments with higher fat content in sinking feeds than extruded floating feeds. In several species, the protein sparing effects of lipids had been reported (Orire and Sadiku 2011;Li et al 2012;Hasan and Khan 2013;Yigit et al 2002;Kikuchi et al 2000) with higher levels of lipids in feeds resulting to higher weight gain in fish. This is in contrast with the results of this study which showed that fish fed on lower lipid level extruded floating feeds attained a higher growth rate than fish fed on sinking feed with higher lipid content.…”

This study evaluated the growth and cost efficiency of tilapia (Oreochromis niloticus) and milkfish (Chanos chanos) fed three feed types used in cage farming in Taal Lake, Batangas, Philippines to serve as baseline information for cage aquaculture regulations. O. niloticus and C. chanos were reared in net cages fed three feed treatments: extruded floating feed (EFF), slow-sinking feed (SSF), and sinking feed (SF). Growth performance, feed conversion ratio (FCR), yield, and cost efficiency were compared at harvest. Results of the study showed that EFF had significantly higher mean weight gain, absolute growth and specific growth rate, biomass harvest, percentage good size fish, and FCR than SF in both O. niloticus and C. chanos (P<0.05), but had no significant difference with SSF in terms of growth parameters (P>0.05). FCR and biomass harvest were significantly higher in EFF than SF in O. niloticus (P<0.05) but were not statistically different in C. chanos (P>0.05). Survival rate was not significantly different among feed types (P>0.05) in both species. Net profit was significantly higher in EFF than the other feed types (P<0.05). At the same volume of fish production in the lake, the use of extruded floating feeds in cages lessened the feed cost by 17.91-29.44% for higher net returns and decreased feeds use by 19.64-30.0%, which could minimize negative impacts on the lake water environment. The results of the study revealed the comparative advantage of floating feeds over slow-sinking feeds and sinking feeds and is therefore recommended as the ideal feed type for cage farming in the lake.

“…This would render the diet unfit for feeding fish. The high level of mortality can be attributed to high level of lipids in the diet which also resulted in loss of appetite and eventual mortality [17,[26][27][28] also reported that, poor utilization of lipid could be attributed to poor feed intake, which prevented the fish from taking enough nutrients to meet the carcass nutrients requirements for the developments of tissues.…”

Attempt in reducing the high cost of feeding in aquaculture through the use of energy rich oils was taken as a means of protein sparing in a feeding trial. Fingerlings of Clarias gariepinus with an average weight of 3.28 ± 0.72g fed three formulated diets and a control (commercial feed-Multifeed), Diet 2 (45% Lipid and 50%CP), Diet 3 (45%Lipid and 40%CP) and Diet 4 (45% Lipid and 30%CP). Results obtained showed significant difference (P<0.05) in the mean weight gain, feed conversion ratio, and specific growth rate compared with control diet (commercial catfish diet). However, diet 4 exhibited highest mortality rate which rendered it inefficient. Diet 4 also gave significantly high (P<0.05) body lipid and correspondingly low body crude protein than diets 2 and 3. Diets 2 and 3 moreover, demonstrated significantly (P<0.05) good growth performances and body compositions than the control. Inferences from this study recommended inclusion of combined varying levels of palm oil, groundnut oil and fish oil in the diets of Clarias gariepinus fingerlings for efficient growth at 45:40 Lipid: Protein ratio (diet3) beyond which there is adverse effects on the growth and survival of Clarias gariepinus fingerlings.

“…Berdasarkan hasil penelitian ini terlihat bahwa fermentasi onggok menggunakan bakteri B. megaterium SS4b mampu mengubah senyawa kompleks menjadi sederhana, yang tercermin dari peningkatan gula sederhana dari 14,36 mg g -1 menjadi 17,07 mg g -1 ; protein terlarut dari 50,96 µg g -1 menjadi 125,18 µg g -1 dan penurunan serat dari 14,83% menjadi 9,42% sehingga mampu meningkatkan kecernaan bahan onggok dari 43,48% menjadi 78,79%. (Orire & Sadiku, 2011). Retensi protein yang tinggi pada akhirnya akan memberikan dampak positif pada peningkatan laju pertumbuhan harian dan efisiensi pakan ikan.…”

Onggok adalah hasil produk samping pengolahan ubi kayu menjadi tapioka yang berpotensi dikembangkan sebagai bahan baku pakan ikan. Permasalahan yang dihadapi yaitu kecernaan onggok masih relatif rendah sehingga perlu ditingkatkan melalui teknik fermentasi. Tujuan penelitian ini adalah mengevaluasi kemampuan bakteri B. megaterium SS4b dalam menyederhanakan nutrien kompleks dari onggok, serta menentukan dosis bakteri yang sesuai untuk proses tersebut. Penelitian ini terdiri atas dua tahap yaitu: 1) penentuan aktivitas enzim selulase, amilase, dan protease bakteri B. megaterium SS4b secara semi-kualitatif; 2) penentuan dosis inokulum yang efektif untuk proses fermentasi onggok (0%, 3%, 6%, dan 9%). Parameter yang diukur meliputi glukosa terlarut/gula pereduksi, protein terlarut, protein kasar, serat kasar, dan kecernaan protein secara in vitro. Percobaan dilakukan menggunakan rancangan acak lengkap (RAL) dengan empat perlakuan beda dosis bakteri untuk fermentasi onggok dan tiga ulangan. Hasil penelitian menunjukkan bahwa B. megaterium SS4b memiliki aktivitas selulase, amilase, dan protease, serta mampu menghidrolisis onggok. Dosis penambahan isolat bakteri sebanyak 9% pada kepadatan 1011 sel/mL dan inkubasi selama 72 jam merupakan dosis terbaik dalam meningkatkan kualitas nutrien onggok. Proses fermentasi ini dapat meningkatkan kandungan protein terlarut, kecernaan protein, ketersediaan gula pereduksi, dan penurunan serat onggok berturut-turut adalah sebesar 2,9 kali, tiga kali, satu kali, dan enam kali dibandingkan dengan kontrol.Cassava starch residue is a by-product in tapioca production that has the potential to be used as one of the ingredients in fish feed. The problem was that the digestibility of cassava starch residue was relatively low but could be improved through fermentation. The purpose of this study was to evaluate the ability of B. megaterium SS4b bacteria in simplifying the nutrient complex of cassava starch residue and determine the appropriate bacterial dose for the process. The study consisted of two stages: 1) determining, semi-qualitatively, the activity of cellulase, amylase, and protease enzyme of B. megaterium SS4; 2) determining the effective inoculum dose for the fermentation process of cassava starch residue (0%, 3%, 6%, and 9%). Parameters measured included dissolved glucose/reducing sugar, dissolved protein, crude protein, crude fibre, and protein digestibility in vitro. The experiment was arranged in a completely randomized design (CRD) with four different treatments of bacterial dose for fermentation of cassava starch residue and three replicates. The results showed that B. megaterium SS4b has cellulase, amylase, and protease activities and was able to hydrolyze cassava starch residue. The dosage level of the bacterial isolate at 9% with a density of 1011 cells mL-1 and incubation for 72 hours was the best treatment in improving the nutrient quality of cassava starch residue. This fermentation process could increase soluble protein content, protein digestibility, availability of reducing sugar, and decrease significantly the fiber content of cassava starch residue
