Betaine Supplementation

Betaine plays some important roles in feed utilization and fish metabolism. The aim of this study was to evaluate the effect of dietary betaine supplementation on the growth performance and feed utilizationin hybrid grouper (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀). A completely randomized experimental design with four dietary levels of betaine, i.e.0.0%, 0.5%, 1.0%, and 2.0% in quadruplicate was done.Hybrid grouper juvenile obtained from Brackishwater Aquaculture Development Center, Situbondo, with an initial body length and body weight of 5.89 ± 0.05 cm and 2.86 ± 0.09 g, respectively was used as the tested animal. The fish was maintained in 60 cm x 40 cm x 40 cm aquaria with 75 L working capacity with individual recirculating system with a fish density of 15 fish/aquarium for 50 days. Experimental diet was provided to apparent satiation twice a day. The results of this study demonstrated that dietary betaine at a level of 0.5% resulted in higher feed utilization efficiency, protein and methionine retentions, and growth performance and lower ammonia excretion than those of the control (P<0.05). Higher antioxidative status was indicated by the lower malondialdehyde (MDA) in the liver of fish fed with betaine supplemented diets at levels of 1 - 2%. In conclusion, betaine supplementation of 0.5% could increase feed utilization efficiency and growth performance of hybdrid grouper.   Keywods: Betaine, Hybrid Grouper, Growth Performance, Feed, Antioxidative Status ABSTRAK Betain memegang beberapa peranan penting dalam pemanfaatan pakan dan metabolisme pada ikan. Penelitian ini bertujuan untuk mengevaluasi pengaruh suplementasi betain pada pakan terhadap kinerja pertumbuhan dan pemanfaatan pakan pada juvenil ikan kerapu hybrid cantang (Epinephelus lanceolatus♂ × Epinephelus fuscoguttatus♀). Penelitian menggunakan rancangan acak lengkap dengan empat perlakuan pakan dengan tingkat suplementasi betain yang berbeda, yaitu 0.0%, 0.5%, 1.0%, dan 2.0% dengan empat ulangan. Juvenil ikan kerapu cantang yang berasal dari Balai Pengembangan Budidaya Laut Situbondo dengan panjang dan bobot awal masing-masing 5.89 ± 0.05 cm and 2.86 ± 0.09 g digunakan sebagai hewan uji dalam penelitian ini. Ikan dipelihara dalam akuarium berukuran 60 cm x 40 cm x 40 cm dengan kapasitas 75L yang dilengkapi dengan sistem resirkulasi individu dengan kepadatan 15 ekor per akuarium selama 50 hari. Pakan uji diberikan hingga sekenyangnya dua kali sehari. Hasil penelitian ini menunjukkan bahwa suplementasi betain sebanyak 0.5% menghasilkan pemanfaatan pakan, retensi protein, retensi metionina, kinerja pertumbuhan dan ekskresi ammonia yang lebih baik daripada kontrol (P<0.05). Status antioksidasi yang lebih juga yang ditunjukkan dengan lebih rendahnya konsentrasi malondialdehid (MDA) pada hati ikan yang diberi pakan dengan suplementasi 1-2% betain. Berdasarkan hasil penelitian dapat disimpulkan bahwa suplementasi betain sebanyak 0.5% dapat meningkatkan efisiensi pemanfaatan pakan dan kinerja pertumbuhan ikan kerapu cantang.

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.
