Abstract:

The kinetics of antibody titers and degree of protection in Indian major carps, catla (Catla catla) and rohu (Labeo rohita) against Aeromonas hydrophila antigen were studied in details at four different age groups of 120, 150, 210 and 270 days old. The first injection (i.m) was given with 0.5 ml of 108 cells/fish of A. hydrophila antigen. The second injection was given on 20 days after the first injection with same dose. The peak antibody titer was observed on day 14 after first injection and on day 7 after second injection in all the age groups of both the species. Higher age groups of fish produced higher level of antibody titers after first as well as second injection. Antibody levels were found to decrease on day 21 after first injection and on day 14 after second injection. The secondary antibody titers were higher to that of antibody primary titers produced in all age groups and was significant (Æ¿<0.05). The level of antibody titers also increased with age within the species. Catla showed higher level of antibody titers compared to rohu in all the age groups after first and second injection. A considerable amount of protection was recorded on day 14 after first injection. High degree of protection was recorded on day 7 after second injection in all the age groups of fish in both the species. The protection levels were higher in older age groups after first as well as second injection and was significant (Æ¿<0.05). Catla showed higher degree of protection compared to rohu in all the age groups.
