| description |
The survival and growth rates of African catfish Clarias gariepinus were reported to be
affected by light conditions. One of the methods to understand the effects of light conditions
on fish survival and growth rates is through analysing the aggressive behavior
of the fish. The objective of the present study was to analyse the aggressive behaviours
of African catfish juveniles under different light wavelengths and light intensities. For
this purpose, the behaviour of African catfish juveniles (age: 34 days old) was observed
under five light wavelengths (white, blue, green, yellow and red) and three light intensities
(0.0014, 0.014, and 1.40 µmoles/m²/s). The results showed that the aggressive
behaviour of the juveniles were significantly affected by light wavelengths and light
intensities. Among five light wavelengths, the juveniles showed less aggressive behaviour
under yellow light wavelength. Futhermore, the juveniles also showed less aggressive
behaviour under 0.0014 µmoles/m²/s. Therefore, rearing of African catfish juveniles
under yellow light wavelength with light intensity of 0.0014 µmoles/m²/s can be
recommended |
