Effect of confinement stress on behaviour, performance, clinicopathological and histopathological alterations of Nile tilapia challenged with aeromonas hydrophila with regard to the blue light as stress inidbitor [electronic resource].

Includes reference.

The present study was carried out to assess the effects of blue light as antistressor and its effect on susceptibility of Nile tilapia (Oreochromis Ililoticus) to Aeromonas hydrophila (A. hydrophila) infection. A total number of (120) O. Ililoticus was divided into 3 experimental groups (40 fish / group). Group 1 (G₁), was exposed to normal day light and considered as control group. Group 2 (G₂), was exposed to blue light. Group 3 (G₃), was exposed to white light (fluorescent illumination). After 15 days of light exposure, fish in groups 2 and 3 were confined into small area and then challenged with A. hydrophila infection.
