Abstract - Issue Jul 2010, 31 (4) BackInfection
and immunization trials of Asian seabass (Lates calcarifer) against
fish pathogen Vibrio anguillarum CAS in Marine Biology, (Received: Abstract:?
Vibriosis is one of the most prevalent fish
diseases caused by bacteria belonging to the genus Vibrio
sp. Fish disease will be controlled by proper vaccination trials and
maintenance of fish form. Pathogenicity for Asian seabass (Lates calcarifer) against V. anguillarum
results in necrosis and haemorrhagic areas near the
base of fins, exopthalmia and ulcers on the skin
surface. Around 50, 100, 200 ?l of formalin killed bacterial cells were
injected (Intraperitoneal) to three different size
(5-10, 20-30, 35-50g) of seabass fishes respectively
and control sere as saline were maintained separately. The Relative Percentage
Survival (RPS) for vaccinated fishes was 60, 75, and 62.5 respectively and the
vaccinations for 20-30 g fishes stay alive. These results stated that the
vaccination for fishes with 20-30 g size may fabricate good immune response. Key
