Abstract
The present study was undertaken to assess the
growth performance and non-specific immune response
of koi carp, Cyprinus carpio exposed to lightemitting
diodes (LEDs): blue (450 nm), green (530
nm), yellow (530 nm) and red (630 nm) under long
photoperiod (16 h light) for 90 days. White fluorescent
light (simulated natural photoperiod, SNP) was
used as control. Growth performance of fish was
higher (p<0.05) in blue-LED and green-LED exposed
groups with significantly higher weight gain percentage,
FER and SGR and lower FCR. The concentrations
of stress indicators: (cortisol and glucose)
were significantly (p<0.05) higher in yellow-LED,
red-LED and for control fish group. Total protein,
globulin protein, lysozyme activity and respiratory
burst activity was significantly higher (p<0.05) in
blue-LED and green-LED exposed fish groups
whereas, yellow-LED and red-LED exposed fish
recorded decline in this parameters after 60 days.
The present study recommends that blue and green
lights are suitable for better growth and improving
the non-specific immune system of koi carp.
