- Abstract
In this study, we investigated the regulation of innate immune responses in olive flounder Paralichthys olivaceus under irradiation with various light-emitting diodes (LEDs), blue (460 nm), green (520 nm), and red (630 nm), at two intensities (0.3 and 0.6 W/m2) for 9 days. To evaluate the effects, we analyzed the levels of melatonin receptor 1 (MTR-1), melatonin, IgM, and lysozyme, which are related to the immunity index. The results showed that melatonin, IgM, and lysozyme significantly decreased during starvation compared to their levels in a normally fed control group. However, the decreases were less pronounced in the green and blue LED-exposed groups than those in the red LED-exposed group during the experimental period. These results confirmed that short-wavelength light (green and blue) is effective in maintaining enhanced immunity in olive flounder.
