High protein content in maggot is one of the advantages for increasing fish growth through artificial feed. This study aimed to find the best optimization and feed formulation for fish meal substitution with maggot meal on growth, feed utilization efficiency, and survival rate of milkfish (C. chanos). Milkfish (C. chanos) with an average weight of 0.62±0.01 gram/fish was used as test fish. Feeding is carried out at 07.00 a.m., 12.00 p.m., and 17:00 p.m. through fixed feeding rate method. The tested fish was kept for 42 days with a stocking density of 1 fish/l. The experimental design used was a completely randomized design with five treatments and three replications. The treatments which had been done were fish meal substitution with maggot meal as follows: A (0%), B (25%), C (50%), D (75%), and E (100%). The research parameters included total feed consumption (TFC), feed utilization efficiency (FUE), protein efficiency ratio (PER), relative growth rate (RGR), survival rate (SR), and water quality. The results showed that the fish meal substitution with maggot meal had a significant effect (p<0.05) on FUE, PER, RGR and had no significant effect (p>0.05) on TFC and SR. The best treatment of each treatment is in treatment C with a composition of 50% maggot meal substitution on fish meal which resulted in a TFC value of 40.17±4.58, FUE of 27.51±0.77, PER of 0.83±0.03%, and RGR of 2.34±0.10.

Tanaman wori merupakan salah satu tanaman kelompok fabaceace yang tumbuh melimpah di Sangihe dan sangat potensial digunakan sebagai salah satu sumber pakan ikan. Kadar protein daun wori adalah 25,53% sehingga berpotensi menjadi protein nabati bagi ikan. Kendala utama yang ditemui ketika memanfaatkan daun tanaman wori adalah kandungan karbohidrat yang tinggi yaitu 48,51% sehingga dapat mempengaruhi proses pencernaan ikan, penyerapan nutrisi yang berujung pada rendahnya pertumbuhan ikan. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh tepung daun wori femerntasi terhadap laju pertumbuhan spesifik dan sintasan hidup ikan nila. Rancangan percobaan yang digunakan adalah Rancangan Acak Lengkap (RAL). Perlakuan yang dilakukan terdiri dari tiga perlakuan dan tiga kali ulangan yaitu kadar tepung daun wori tanpa fermentasi A (kontrol) 10%, kemudian B tepung daun wori fermentasi (10%), dan C tepung daun wori fermentasi (20%). Laju pertumbuhan spesifik dan efisiensi pakan diuji menggunakan ANOVA sedangkan sintasan hidup akan dianalisis secara deskriptif. Hasil penelitian ini menunjukan bahwa penambahan tepung wori fermenasi dalam pakan dapat meningkatkan nilai laju pertumbuhan spesfik ikan nila dan efisiensi pemanfaatan pakan dengan nilai tertinggi pada perlakuan C yaitu SGR 1,94%/hari. Sementara itu, untuk semua perlakuan nilai sintasan hidup sebesar 100%.   The wori plant is one of the plants of the fabaceace group that grows abundantly in Sangihe and has potential to be used as a source of fish feed. The protein content of wori leaves is 25.53%, so it has the potential to become vegetable protein for fish. The main obstacle encountered when utilizing wori plant leaves is the high carbohydrate content of 48.51% so that it can affect the digestion process of fish, nutrient absorption which lead to low fish growth. The purpose of this study was to determine the effect of wori femerntation leaf meal on the specific growth rate and survival of tilapia. The experimental design used was a completely randomized design (CRD). The treatments consisted of three treatments and three replications, namely the content of fermented wori leaf powder, A (control) 10%, then B fermented wori leaf powder (10%), and C fermented wori leaf powder (20%). Specific growth rate and feed efficiency were tested using ANOVA, while survival rate was analyzed descriptively. The results of this study indicate that the addition of fermented wori powder in the feed can increase the value of the specific growth rate of tilapia and feed utilization efficiency with the highest value in treatment C, namely SGR 1.94% / day. Meanwhile, for all treatments the survival rate was 100%.

<p>ABSTRACT</p><p><br />This experiment was conducted to evaluate the use of by product of corn ethanol industry, DDGS (distiller dried grain with soluble) and hominy as feed raw material on digestibility and the growth performance of humpback grouper Cromileptes altivelis juvenile. Three experimental diets containing isoprotein (48%) but different in DDGS contain were used. Diet A containing 0% of DDGS and hominy while diet B and C containing 10.13% (6.13% of DDGS and 4% of hominy) and 19.05% (15.05% of DDGS and 4% of hominy). Reduce of fish meal level in the diet was happen as a consequence of balancing amino acid. For digestibility experiment and Cr2O3 at level of 0.05% was used as a tracer. The feces were daily collected 30‒60 minutes after feeding for 14 days. Dry matter and protein were used as digestibility parameters. Completely randomized design with three treatments and two replicates was used in this experiment. Humpback grouper with an average weight of 11‒14 g were reared at floating net cages (FNG) of 3×2×1.5 m3. The stocking density for each cage was 167 fish/FNG and reared for six months. For digestibility measurement 30 fish were held in cylindrical fiber tank filled with 800 L of sea water. Fish were fed three times daily at satiation level. For maintaining net in a clean condition net was changed in every ten days. Feed consumption, digestibility of protein and total, growth performance indicator i,e specific growth rate, feed efficiency protein and lipid retention were used as evaluating parameters. The results showed that the fish fed with diet containing DDGS (6.13%) dan hominy (4%), at the level of 10.13% (diet B), shows similar growth performance indicators with the fish fed diet A (0% of DDGS and hominy) and the growth performance indicator was higher when being compared to those fish fed diet C (containing 19.05% of DDGS (15.05%) and hominy (4%)) (p&lt;0.05). More over the inclusion of DDGS and hominy at the level of 10,13% give no negatif impact to feed palatability (shown by total feed consumption value) and digestibility of protein. The increasing level of DDGS and hominy more than 10% reduced palatability and protein digestibility. Based on this research, DDGS and hominy can be used up to 10% in the feed formulation of humpback grouper</p><p><br />Keywords: digestibility, growth performance, DDGS, hominy, humpback grouper, Cromileptes altivelis</p><p><br />ABSTRAK</p><p><br />Penelitian ini dilakukan untuk mengevaluasi pemanfaatan limbah jagung dari industri etanol dalam bentuk distillate dried grain with soluble (DDGS) dan homini sebagai bahan baku pakan terhadap kinerja pertumbuhan ikan kerapu bebek Cromiliptes altivelis. Ikan yang digunakan dalam penelitian ini adalah juvenil ikan kerapu bebek berukuran 11‒14 g. Ikan dipelihara dalam karamba jaring apung yang berukuran 3×1,5×2 m3 dengan kepadatan 167 ekor/jaring.

Feed Utilization Efficiency

Feed utilization efficiency is one of the problems that often faced by tiger shrimp (Penaeus monodon Fabricus) farmers, which is 40-60% of production costs used for feed. The efficiency of feed can be improved by the addition of the bromelains in the feed, which can hydrolyze proteins into simpler compounds to increase the digestibility of the feed protein. This study aims to examine the effect of bromelains in feed on protein digestibility (ADCp), feed utilization efficiency (EPP), and growth (RGR) of tiger shrimp. Tiger shrimp with an average weight of 2.8 ± 0.26 g / individual was obtained from the Brackish Water Aquaculture Development Centre (BBPBAP), Jepara. There were 6 treatments adding bromelains in the feed, A (0%), B (0.2%), C (0.4%), D (0.6%) and E (0.8%). Observation parameters, including ADCp, EPP, PER, RGR, SR, and water quality parameters. The results showed that the addition of the bromelains in feed increased ADCp, EPP, PER, RGR, but had no effect on the SR of tiger shrimp. Bromelains (0.4% / kg) of feed is the optimal dose of ADCp, EPP, and RGR, resulting in a maximum value of 82.59%, 88.17%, and 5.24% / day.   Permasalahan yang sering dihadapi pembudidaya udang windu (Penaeus monodon Fabricius) adalah efisiensi pemanfaatan pakan yang belum maksimal sehingga hampir 40-60% dari total biaya produksi untuk biaya pakan. Efisiensi pemanfaatan pakan dapat ditingkatkan dengan penambahan enzim bromelin dalam pakan yang mampu menghidrolisis protein menjadi senyawa yang lebih sederhana sehingga dapat meningkatkan daya cerna protein pakan. Penelitian ini bertujuan mengkaji pengaruh enzim bromelin dalam pakan terhadap kecernaan protein (ADCp), efisiensi pemanfaatan pakan (EPP) dan pertumbuhan (RGR) udang windu. Hewan uji berupa udang windu dengan bobot rata-rata 2,8±0,26 g/ekor diperoleh dari Balai Besar Perikanan Budidaya Air Payau (BBPBAP), Jepara sebagai tempat penelitian. Terdapat 6 perlakuan penambahan enzim bromelin dalam pakan yaitu A (0 %), B (0,2 %), C (0,4 %), D (0,6 %) dan E (0,8 %). Pengamatan parameter meliputi ADCp, EPP, PER, RGR, SR dan parameter kualitas air. Hasil penelitian menunjukkan bahwa penambahan enzim bromelin dalam pakan meningkatkan ADCp, EPP, PER, RGR, namun tidak berpengaruh pada SR udang windu. Enzim bromelin 0,4%/kg pakan merupakan dosis optimal pada ADCp, EPP dan RGR menghasilkan nilai maksimal sebesar 82,59%, 88,17% dan 5,24%/hari.

 Catfish (Pangasius sp.) Is one of the most cultivated freshwater fish, because it is one of the fish that has a high economic value. However, the use of phytopharmaca is used to improve feed efficiency and fish growth. One of the phytopharmaca which can be used as an antimicrobial is temulawak (Curcuma xanthorrhiza Roxb). This study aims to determine the optimal dose of the effect of temulawak extract on artificial feed in increasing feed consumption, efficiency of feed utilization, and growth rate of catfish (Pangasius sp.). The test fish is maintained with a stocking density of 1 tail / l with a maintenance time of 42 days. This study used an experimental method with 4 treatments and 3 replications. The treatments in this study were Treatment A (addition of 0 ml ginger extract), B (addition of 6 ml temulawak extract), C (addition of 12 ml curcuma extract), and D (addition of 18 ml ginger extract). The data observed included absolute weight, crime scene, EPP, SGR, REP, SR and water quality. The results showed that the addition of temulawak extract to artificial feed had a very significant effect on absolute weights, crime scenes, EPP, SGR, REP but did not differ significantly for survival. The optimum dose of addition of curcuma extract to total feed consumption is 11 ml capable of producing a maximum crime scene of 168.1 g, efficiency of feed utilization is 10.5 ml capable of producing a maximum EPP of 70.3% and specific growth rate is 10.8 ml resulting in maximum SGR 2.46% / day

Tilapia is an economically important fish and is widely cultivated in Indonesia. More food in tilapia farming uses fish meal which needs to be replaced because of dependence as an imported product that affects production costs. One of the local raw materials that can be used as a source of animal protein is magot. This study aims to analyze the right proportion of magot flour with a combination of fish meal and magot flour in feed so as to produce maximum growth and feed efficiency for tilapia seeds. This research was conducted in September to December 2019. Test fish used were tilapia seeds measuring 1-2 cm with an average weight of 0.16 g with a stocking density of 1 fish / m3. Fish are fed twice a day with a percentage of daily feeding of 3% of fish biomass. This study used a completely randomized design (CRD) with five treatments and three replications. The treatment in this research is, treatment A = substitution of fish meal 100% with magot flour 0%, B = substitution of fish meal 75% with magot flour 25%, C = substitution of fish meal 50% with magot flour 50%, D = substitution of flour fish 25% with 75% magot flour, E = substitution of 0% fish flour with 100% magot flour. Data were analyzed using analysis of variance (ANOVA) if there were significantly different treatment effects followed by Duncan's Multiple Range Test with a significance level of 0.05. The results showed that the addition of magot flour 50% gave a significant result (P <0.05) on protein retention with a value of 14.83%, a specific growth rate with a value of 2.00%, absolute weight growth with a value of 4.34 g, and efficiency of utilization feed with a value of 93.59%. No effects were found in the the feed consumption rate and fish survival. Treatment C combination of 50% fish meal and magot flour can give the best results for the growth of Nirwana race Tilapia.
