Light colour influences the behaviour and stress physiology of captive tench (Tinca tinca)

Light colour influences the behaviour and stress physiology of captive tench (Tinca tinca)

Groups of juvenile tench (7.02 ± 0.28 g) were reared under four different light regimes; blue light, red light (80 Wm −2 12L:12D photoperiod) white light (912 ± 210 lux, 80 Wm −2 , 12L:12D photoperiod) and no light (0 lux) (0L:24D). Visibility of fish out of shelters was used as an indicator of acti...

Zusammenfassung:Groups of juvenile tench (7.02 ± 0.28 g) were reared under four different light regimes; blue light, red light (80 Wm −2 12L:12D photoperiod) white light (912 ± 210 lux, 80 Wm −2 , 12L:12D photoperiod) and no light (0 lux) (0L:24D). Visibility of fish out of shelters was used as an indicator of activity and was monitored by video recording. Blood plasma cortisol concentrations were also measured. Fish under blue or white light were significantly less active during the photophase than those under red or no light ( P
