Impact of different environmental factors on the circulating immunoglobulin levels in the Nile tilapia, Oreochromis niloticus
Immunoglobulin M (IgM) in teleost fishes is the only component of the specific humoral defense system that is affected by environmental factors.

| description | Immunoglobulin M (IgM) in teleost fishes is the only component of the specific humoral defense system that is affected by environmental factors. In the present study, we examined the effect of various environmental factors (water temperature, salinity, pH and suspended solids) on the plasma IgM in the Nile tilapia,
Oreochromis niloticus. For all treatments, fish were acclimatized in particular environmental conditions for 2 or 4 weeks. For fish reared at 18.4, 23 and 28 °C, the circulating IgM concentration increased with increased water temperature for 2 weeks. Rearing the fish at 33 °C resulted in a decrease in IgM concentration, suggesting that the fish possess an appropriate thermal range for production of immune substances. Plasma level of IgM increased significantly with salinity at 12 and 24 parts per thousand (ppt). On the other hand, plasma IgM concentration did not change by exposing the fish to acidification (pH 4.0) and suspended solids (20, 200, and 2000 mg/l). These results suggest that the specific immune system of tilapia changes by certain factors in aquatic environment. |
