Abstract

Curcuma spp. is a phytobiotic with potential application in fish farming. This study aimed to evaluate the potential of Curcuma zedoaria, Curcuma aeruginosa and Curcuma mangga extracts in striped catfish infected with Aeromonas hydrophila. The study used a complete randomized design (CRD) consisting of six treatments: KN (negative control), KP (positive control, fish infected without treatment), PE (C. zedoaria extract 6.25 g kg-1), HE (C. aeruginosa extract 6.25 g kg-1), ME (C. mangga extract 6.25 g kg-1) and KE (combination of C. zedoaria extract 2.1 g kg-1 + C. aeruginosa extract 2.1 g kg-1 + C. mangga extract 2.1 g kg-1). A total of 360 striped catfish, 10 ± 0.5 cm were kept in 18 aquariums measuring 50 × 40 × 35 cm3 and fed the treatment for 30 days. The challenge test was conducted on day 31 by injecting A. hydrophila suspension (106 colony-forming units (CFU) mL-1) intramuscularly into fish. The results showed that the treatment administered were able to stimulate the expression of interleukin-1â, interferon-ã 2a, 2b genes, increase the number of red and white blood cells, hematocrit, hemoglobin, phagocytosis activity, respiratory burst, reduce the population of A. hydrophila in the intestine, and reduce tissue damage in striped catfish. Striped catfish treated with the extracts showed significantly higher survival rates (p<0.05) compared to the positive control group. The survival rates were: KN (100.00 %), KP (53.33%), PE (93.33 %), HE (91.67 %), ME (93.33 %), and KE (88.33 %). In conclusion, the treatment administered were able to enhance the immune response and resistance of striped catfish infected with A. hydrophila.

Abstract

Vibrio parahaemolyticus strain that produces PirA and PirB toxins is the main causative agent of Acute Hepatopancreatic Necrosis Disease (AHPND) in vannamei shrimp. This study aimed to evaluate the effect of biofloc application, probiotic Pseudoalteromonas piscicida 1Ub, and their combination on growth, immune response and resistance of vannamei shrimp infected with V. parahaemolyticus strain. This study used a completely randomized design consisting of biofloc-based system treatment with or without probiotic 1Ub and normal seawater as control. All treatment groups were challenged with V. parahaemolyticus AHPND strain at a cell density of 105 CFU mL”1 through immersion, while the negative control was reared without being pathogenic challenged. The shrimp used were in averaged body weight of 1.3 ± 0.002 g, reared for 21 days and fed five times a day at 06:00, 10:00, 14:00, 18:00, and 22:00 WIB. The results showed that the B+Pro combination challenge test treatment resulted the best growth performance (specific growth rate, absolute length gain and feed conversion ratio) (P<0.05) compared to other challenge test treatments. hrimp treated with B+Pro also showed a lower intestinal cell population of V. parahaemolyticus RfR, and significantly higher immune response values (P<0.05) than those of other challenge test treatments and K+. Furthermore, those parameters supported positive impact on final shrimp survival rates in the experiment. This study shows that the application of combination of biofloc and 1Ub probiotic bacteria can significantly protect and increase the resistance of vannamei shrimp to V. parahaemolyticus AHPND infection.

Abstract

Perilaku kanibal pada benih ikan baung (Hemibagrus nemurus) menjadi permasalahan pada pembenihannya. Salah satu pendekatan yang sudah dilakukan untuk mengendalikan kanibalisme pada ikan adalah pemberian triptofan.  Penelitian ini bertujuan untuk mengetahui pengaruh triptofan terhadap kejadian kanibalisme dan kandungan konsentrasi hormon steroid pada benih ikan baung. Panjang awal benih yang digunakan adalah 4,98±0,1 cm yang dipelihara di dalam akuarium berkapasitas 20 L dengan kepadatan 3 ekor per L.  Selama penelitian, benih ikan baung diberi pakan komersial (40% protein) yang disuplementasi triptofan dengan konsentrasi berbeda, yaitu tanpa suplementasi triptofan (A), suplementasi triptofan 0,25% (B), suplementasi triptofan 0,50% (C), suplementasi triptofan 0,75% (D), dan suplementasi triptofan 1% (E). Setiap perlakuan terdiri dari tiga kali ulangan. Pakan diberikan empat kali sehari secara satiasi. Parameter yang diamati adalah tipe kanibal, indeks kanibal, kematian normal, sintasan, performa pertumbuhan serta konsentrasi hormon (estradiol, testosteron, dan kortisol). Hasil penelitian menunjukkan bahwa pemberian pakan yang diperkaya triptofan memberikan penurunan kejadian kanibal dan peningkatan sintasan benih ikan baung. Pemberian triptofan juga menurunkan kandungan estradiol tubuh, dan penurunan ini ada kaitannya dengan penurunan kejadian kanibalisme. Performa pertumbuhan benih ikan baung meningkat dengan pemberian pakan yang ditambahkan triptofan.  Hasil penelitian ini menunjukkan bahwa suplementasi 0,50–0,75% triptofan pada pakan efektif menurunkan kejadian kanibalisme pada benih ikan baung.The cannibal behavior of Asian redtail catfish (Hemibagrus nemurus) is a problem in the hatchery. One approach that has been used to control cannibalism in fish is the use of tryptophan. This study aimed to determine the effect of tryptophan on the incidence of cannibalism and the content of steroid hormones in Asian redtail catfish juveniles. The study was conducted using the fish with a body length of 4.98±0.14 cm reared in aquariums with a water volume of 20 L with a density of 3 fish per L. Fish were given commercial feed (40% protein) supplemented with tryptophan with different concentrations, namely without tryptophan supplementation (A), tryptophan supplementation 0.25% (B), tryptophan supplementation 0.5% (C), tryptophan supplementation 0.75% (D), and tryptophan supplementation 1% (E). Each treatment consisted of three replications. Feed were given four times a day at satiation level. Parameters observed were cannibal type, cannibal index, normal mortality, survival rate, growth performance, and hormone concentration (estradiol, testosterone, and cortisol). The results showed that giving tryptophan through feed decreased the incidence of cannibalism and increased the survival of Asian redtail catfish juveniles. The addition of tryptophan to the feed decreased the concentration of estradiol in the body of fish and it is associated with a decrease in the incidence of cannibalism, thereby improving survival.  Furthermore, the supplementation of tryptophan also increased growth performance. The results of this study showed that supplementation of 0.50-0.75% tryptophan in feed was effective in reducing the incidence of cannibals in Asian redtail catfish juveniles.
