Performa pertumbuhan benih ikan gabus Channa striata yang diberi hormon pertumbuhan rekombinan melalui pakan buatan

Abstract

Ikan gabus memiliki nilai ekonomis tinggi dan bermanfaat bagi kesehatan, namun budidayanya memiliki tantangan seperti biaya pakan yang tinggi dan pertumbuhan yang lambat. Solusi yang dapat dilakukan diantaranya penggunaan hormon pertumbuhan untuk memacu pertumbuhan somatik. Tujuan penelitian ini adalah untuk menguji efektivitas pemberian hormon pertumbuhan rekombinan (rEIGH) melalui pakan buatan terhadap pertumbuhan benih ikan gabus. Penelitian ini mencakup dua perlakuan dengan empat kali ulangan, yaitu tanpa penambahan rElGH pada pakan dan penambahan rElGH pada pakan sebanyak 5 mg/kg pakan. Benih ikan gabus dengan (panjang 6,5

Snakehead fish has high economic value and is beneficial for health, however, its cultivation faces challenges such as high feed costs and slow growth. Solutions such as the use of growth hormones to support optimal growth can be implemented. The aim of this research is to identify the effectiveness of recombinant growth hormone (rElGH) administration through artificial feed on the growth of snakehead fish seeds. The study comprises two treatments with four replications each: one without the addition of rElGH to the feed, and the other with the addition of rElGH to the feed at a dosage of 5 mg/kg of feed. The snakehead fish seeds (body length 6.5 ± 0.07 cm; weight of 2.10 ± 0.12 g; width 0.44 ± 0.03 cm), reared using cages sized 1.0 × 1.0 × 1.0 m3 with a stocking density of 30 individuals/m2. The fish seeds are reared for 60 days using the at satiation feeding method with pellets containing 34-36% protein. During the study period, rElGH feed was administered only during the first week, followed by feeding without rGH. The results of the study show that oral administration of recombinant growth hormone (rElGH) at a dosage of 5 mg/kg of feed to snakehead fish seeds can enhance growth. This dosage resulted in a 52.80% greater increase in weight compared to the control group, while length and width growth also increased by 34.74% and 12.27% respectively compared to the control group.
