EVALUASI PEMBERIAN PROBIOTIK BACILLUS PADA MEDIA PEMELIHARAAN TERHADAP LAJU PERTUMBUHAN DAN PERUBAHAN HISTOPATOLOGI IKAN LELE DUMBO (Clarias gariepinus) YANG DIINFEKSI Aeromonas hydrophila
Abstract: The aim of this
study was to evaluate the addition of a probiotic Bacillus on culture medium
through growth rate and histopathological change in African Catfish who was
infected by Aeromonas hydrophila. The study consisted of five treatments such
as the addition of probiotic Bacillus ND2, Bacillus P4I2, Bacillus ND2 + Bacillus
P4I2 (Kom), positive control (K+) and negative control (K-) (without probiotic
addition). African Catfish (13.354±2.8 g) was maintained in 15 aquariums (40 L
in volume) with 30 fishes each for 30 days. Probiotic bacteria was applied in
water once a day, whereas pathogenic bacteria A. hydrophila (103 CFU/mL) were added once in earlier
treatment (except for the negative control) as assumption that A. hydrophila
will shape up quorum sensing in unfortunate condition. The result showed that
the highest spesific growth rate in the treatment of Bacillus ND2 probiotics
(1,708 ± 0.114%). Histopathology showed that damaged of liver dan kidney in
probiotics treatment were lightner than positive control (K+). The addition of Bacillus P4I1 (104 CFU/mL)
efective to increased the spesific growth rate of African Catfish and prevent
the damage of liver and kidney of African Catfish was infected by Aeromoniasis.
