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 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 < 0.01). Red light produced similar activity patterns to fish receiving 24 h darkness. Plasma cortisol concentrations were also significantly influenced (P < 0.05) with the fish under white light having the highest plasma cortisol concentration (317 ± 62 ng cm−3) compared to fish in the dark treatment (106 ± 36 ng cm−3). Thus, the provision of coloured light filters increases activity in juvenile tench and may reduce their intrinsic stress level. Reviews in Fish Biology and Fisheries Springer Journals
