Seaweed extract of Gracilaria verrucosa as an antibacterial and treatment against Vibrio harveyi infection of Litopenaeus vannamei
ABSTRACT The objectives of this study were to investigate the antibacterial activity of G. verrucosa extract in test inhibitory zone with different concentrations (500, 1000, 1500, and 2000 mg/L) and to examine G. verrucosa extract with different dosage (0.5, 1.0, 1.5, 2.0 g/kg) in feed on immune r...

| description | ABSTRACT
The objectives of this study were to investigate the antibacterial activity of G. verrucosa extract in test inhibitory zone with different concentrations (500, 1000, 1500, and 2000 mg/L) and to examine G. verrucosa extract with different dosage (0.5, 1.0, 1.5, 2.0 g/kg) in feed on immune responses (total hemocytes count, phagocytic activity, phenoloxidase activity, respiratory burst) and survival rate in the Litopenaeus vannamei against the pathogenic Vibrio harveyi. Pacific white shrimp with an initial body weight of 5.25±0.55 g was reared in the aquarium (60×30×30 cm3) with a density of 10 shrimp/aquarium. Pacific white shrimp had been fed three times a day as much as 3% in at satiation for 14 days after challenged with V. harveyi. The first results of the inhibitory test showed that all the concentration of G. verrucosa extract was able to inhibit the growth of V. harveyi and the second result showed that the extract of G. verrucosa can increase the immune responses of shrimp. In the result of survival showed that shrimp fed with 0.5, 1.0, 1.5, and 2.0 g/kg has 80, 73, 70, and 70%, respectively. In conclusion, the seaweed extract of G. verrucosa has antibacterial activity and can induce the immune responses and resistance of Pacific white shrimp against V. harveyi infection.

ABSTRAK
Tujuan dari penelitian ini adalah untuk menguji aktivitas antibakteri ekstrak G. verrucosa dalam uji zona hambat dengan konsentrasi yang berbeda (yaitu 500, 1000, 1500, dan 2000 mg/L) dan studi perlakuan pengobatan untuk menguji ekstrak G. verrucosa pada pakan dengan dosis yang berbeda (yaitu 0,5; 1,0; 1,5; dan 2,0 g/kg) pada respons imun (yaitu jumlah total hemosit, aktivitas fagositik, aktivitas fenoloksidase, respiratory burst) dan tingkat kelangsungan hidup pada udang vaname terhadap bakteri patogen Vibrio harveyi. Udang vaname dengan berat badan awal 5,25 ± 0,55 g dipelihara di akuarium (60 × 30 × 30 cm3) dengan kepadatan 10 udang/akuarium. Udang vaname pasifik diberi makan tiga kali sehari 3% at satiation selama 14 hari setelah di uji tantang V. harveyi. Hasil pertama dari uji zona hambat menunjukkan bahwa semua konsentrasi ekstrak G. verrucosa mampu menghambat pertumbuhan V. harveyi dan hasil kedua menunjukkan bahwa pemberian ektrak G. verrucosa dapat meningkatkan respon imun udang. Hasil tingkat kelangsungan hidup menunjukkan bahwa perlakuan pakan udang dengan dosis 0,5; 1,0; 1,5; dan 2,0 g/kg memiliki tingkat kelangsungan hidup masing-masing 80, 73, 70, dan 70%. Kesimpulannya, ekstrak rumput laut G. verrucosa memiliki aktivitas antibakteri dan dapat menginduksi respons imun & ketahanan udang terhadap infeksi V. harveyi.
