Abstract

Efficient dietary protein utilization is essential to reduce feed costs and environmental impacts in sustainable aquaculture. This study aimed to evaluate the effects of cinnamaldehyde (CA) supplementation in feed with various energy-to-protein (E:P) ratios on the chemical composition of Pangasianodon hypophthalmus. The five feed formulas that made up the treatment feed were as follows: 28:13-C0 (28 % Protein with an E:P ratio of 13 and CIN 0 g kg-1); 25:14-C1 (25 % protein with an E:P ratio of 14 and CIN 1.2 g kg-1); 25:14-C2 (25 % protein with an E:P ratio of 14 and CIN 1.7 g kg-1); 25:15-C1 (25 % protein with an E:P ratio of 15 and CIN 1.2 g kg-1); and 25:15-C2 (25 % Protein with an E:P ratio of 15 and CIN 1.7 g kg-1). Striped catfish weighing 28.06 ± 0.19 g were placed in a hapa (2 × 1 × 1 m3) at a density of 25 fish per cage. Fish were fed to apparent satiation three times daily for 60 d. The 25:14-C2, 25:15-C1, and 25:15-C2 diets increased albumin levels and reduced cholesterol, while 25:15-C2 also yielded the highest total protein and lowest triglyceride levels. Growth performance and feed efficiency were comparable among 28:13-C0, 25:14-C2, 25:15-C1, and 25:15-C2 (final weight: 141.62–143.75 g; FCR: 1.16–1.19). Protein efficiency ratio was highest in 25:15-C1 and 25:15-C2, whereas protein retention peaked in 25:14-C2. The hepatosomatic index was elevated in 25:14-C1, 25:14-C2, and 25:15-C1. Body lipid content was highest in 25:15-C1, while muscle lipid content was lowest in 25:14-C2 and 25:15-C1. Reducing dietary protein from 28 % to 25 % did not compromise growth performance at the E:P ratio level of 15 with a supplementation of 1.2 g kg-1 CIN.

Abstract

Penelitian ini adalah bertujuan untuk mengkaji efek penambahan enzim bromelin dalam pakan terhadap pertumbuhan ikan nila (Oreochromis niloticus) selama tahap pembenihan. Penelitian ini menggunakanRancangan Acak Lengkap (RAL) dengan empat perlakuan pakan yang mengandung bromelin pada kadar 0, 5, 10, serta 15 g kg-1 pakan dan masing-masing diulang sebanyak empat kali. Seratus larva ikan nila, bobotawal rata-rata 0,06±0,02 (g), umur 7 hari ditebar perakuarium dengan volume air 90 L, lalu dipelihara selama 40 hari. Pemberian pakan dilakukan lima kali sehari hingga ikan mencapai tingkat kenyang (at satiation) selama masa pemeliharaan 20 hari pertama dan 4 kali sehari pada 20 hari berikutnya. Hasil penelitian ini membuktikan bahwa penambahan bromelin pada pakan dapat meningkatkan efisiensi pemanfaatan pakan oleh ikan nila karena dapat meningkatkan biomassa ikan (280,60±2,31), rasio efisiensi protein (2,22±0,02), serta menurunkan rasio konversi pakan (1,12±0,01). Bobot individu ikan tidak berbeda nyata antar perlakuan, namun nilai kelangsungan hidup yang tinggi pada perlakuan penambahan bromelin 10 g kg-1, menyebabkan biomassa ikan panen meningkat secara signifikan yang berbeda nyata dari perlakuan 0 g kg-1. Dengan demikian dapat disimpulkan bahwa dosis terbaik penambahan bromelin di fase pembenihan ikan nila adalah 10 g kg-1.

Abstract

Copper (Cu-O) is a micromineral required in small amounts in the body, yet it plays an important role in the metabolism and health of fish. This study aimed to evaluate the growth performance of tilapia (Oreochromis sp.) fed diets supplemented with organic copper (Cu-O). Four treatments were tested: K (control, without Cu-O), Cu-O 1 (1 mg kg⁻¹ Cu-O), Cu-O 2 (2 mg kg⁻¹ Cu-O), and Cu-O 3 (3 mg kg⁻¹ Cu-O). Fifteen tilapia with an average initial weight of 8.75 ± 0.02 g were reared in aquaria (60 × 50 × 40 cm, water depth 30 cm) for 60 days. Fish were fed to satiation three times daily. The results showed that the growth parameters of tilapia fed Cu-O-supplemented diets were significantly higher (P < 0.05) than those of the control. The optimal dose of Cu-O supplementation was found to be 2 mg kg⁻¹ feed; subsequent studies should investigate interspecies variations and refine dosage recommendations accordingly.

Abstract

Siganid is better known as rabbit fish. In hatcheries, constraint that is still faced is the low survival, which was assumed to occur because of the timing for initial feeding is not solidly known. This research aimed to examine the best initial feeding time for siganus, based on evaluation on eyes and yolk reserves during the transition. The research was conducted from 24-29 March 2021 in IPUW Barru, South Sulawesi. Larvae were obtained from the second progeny (G2) of domesticated Siganus guttatus. Larvae were reared for 5-6 days without feeding. Evaluated parameters include eyes diameter and yolk reserves. Samples were observed with microscope and will be explained descriptively. Water quality parameters were measured, namely DO, salinity, pH and temperature. Eyes diameter at 6 Hour After Hatching (HAH) ranges between 81.5-128.9 m, 13 HAH= 125.5-167.7 m, 24 HAH= 138.2-213.9 m, two days after hatching 2 Day After Hatching (DAH) = 113.6-193.1 m, 3 DAH= 163.1-219.2 m, 4 DAH= 190.4-212.6 m. Yolk reserves diameter ranged between 137-194m (6 HAH), 13 HAH= 152-191m, 24 HAH= 94.0-185m, 2 DAH= 75.3-99.63m, 3 DAH= 42.33-87.58m, 4 DAH= 38.17-55.59m. After age 5 DAH, there are no larvae found alive (dead). Eyes developed at age 6 HAH and experienced pigmentation at age 24 HAH. Conversely, yolk reserves diameters were getting smaller since age 24 HAH and completely disappear at age 4 DAH. It indicates that eyes effectively see feeds at age 2 DAH. Therefore, initial feeding should be started. The water quality parameters measured were still in normal conditions according to the life of S. guttatus larvae. From this research, it can be concluded that eyes have been well functioned at age 2 DAH and yolk reserves was finished at age 4 DAH. Therefore, the initial feeding should be done at the age of 2 DAH.Keywords:Development, Siganus guttatus larvae,Transition
