EFEKTIVITAS KOMBINASI VAKSIN BAKTERI POLIVALEN DENGAN VAKSIN ANTI GROUPER SLEEPY DISEASE IRIDOVIRUS (GSDIV) PADA IKAN KERAPU MACAN (Epinephelus fuscoguttatus)
Abstract: One problem in
mariculture is mortality caused by diseases. An experiment to evaluate the
effectiveness of polyvalent bacterial vaccine combined with anti GSDIV vaccine
was conducted in the Institute for Mariculture Research and Development,
Gondol, Bali. Polyvalent bacterial vaccine was combined of three inactivated
pathogens, i.e. Vibrio harveyi, V. alginolyticus, and Photobacterium
leioghnathi. Polyvalent bacterial vaccine administered through bathing method
whereas GSDIV vaccine given through intra-peritoneal injection on tiger
grouper. The fish was reared for three months in concrete tanks equipped with
filter and aeration systems. The fish were fed with dry pellet twice a day. The
results showed that titer antibody and survival rate of vaccinated fish were
higher than unvaccinated one. The highest titer antibody was obtained on fish
vaccinated with GSDIV vaccine (128) followed by fish vaccinated with polyvalent
bacterial vaccine (32-64) and combination of polyvalent bacterial vaccine with
GSDIV vaccine (32-64), respectively. Relative Percentage Survival (RPS) of
vaccinated fish following challenge with live bacteria and virus were ranged
from 65-84%. It is suggested that vaccines effective to enhance immune
protection of tiger grouper fish against bacterial and viral infections.
