Photoperiod influence on the cultivation of Steindachneridion scriptum (Pisces, Pimelodidae) juvenile [PDF]
Brazilian Archives of Biology and Technology, 2008 This study aimed to evaluate the influence of photoperiod on juvenile suruvi (Steindachneridion scriptum) in six photoperiods: 24L-0D (L= Light; D= Dark), 18L-6D, 14L-10D, 10L-14D, 6L-18D and 0L-24D.
