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.

Chitosan is a functional polysaccharide that is capable of inducing various biological activities. This research aims to examine the effect of chitosan on growth and blood profile of tilapia fish. The method used in this research was experimental methods with completely randomized design (RAL) consisting of 4 treatments and 3 times. 120 Tilapia fish in 5-7 cm in range size were reared in aquarium at density of 10 fish/aquarium. Feedwere given at the additional dose of 10 ppt, 50 ppt, and 100 ppt chitosan. The observed variables were growth rate, survival rate, fish blood profile, water quality, feed utilization efficien . The results showed that the best chitosan treatment was at a dose of 100 ppt which produced FCR of 3.48 ± 2.25, AGP: 0.13 ± 0.03, SGR: 0.85 ± 0.84 and EPP: 28.70 ± 16,54.

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.

Abstract Purpose Black soldier fly transforms organic waste into insect protein and fat, which makes it valuable for ecological utilization. This process is associated with the intestinal microbiota. This research was developed to determine the type and functional characteristics of intestinal microbiota present in black soldier fly larvae. Methods In this research, metagenomics has been used to study black soldier fly larvae gut bacteria, which involves the high abundance of the gut microbe advantage bacterium group, the impact, and the physiological functions of the microbiota. Furthermore, intestinal bacteria and their related functions were investigated by bioinformatics analysis to evaluate potential microbial strains that may be used to improve feed utilization efficiency in factory farming. Result The results showed that black soldier fly larvae’s intestine contains more than 11,000 bacteria. The high relative abundance of group W (larvae fed with 75% wheat bran and 25% soybean powder) may promote feed utilization efficiency, whereas high relative abundance of group T microbiota (larvae fed with 75% wheat bran and 25% soybean powder supplemented with 1% tetracycline) may play an important role in black soldier fly larvae survival. Conclusion The gut bacteria in black soldier fly larvae were involved in polysaccharide biosynthesis and metabolism, translation, membrane transport, energy metabolism, cytoskeleton, extracellular structures, inorganic ion transport and metabolism, nucleotide metabolism, and coenzyme transport physiological processes. The 35 significant differential microbes in group W may have a positive impact on feed utilization and physiological process.
