Fish reared under the red-long photoperiod had the highest concentration of the selected parameters of the coelomic fluid. Moreover, significant differences were noted in the all the parameters in fish reared under the red-long photoperiod in comparison with fish from the other treatments (P < 0.05). The results indicate that light (color and photoperiod) influences egg quality during the final stage of A. ruthenus reproduction.
