Effect of Two Levels of Temperature and Natural and Artificial Photoperiod on Growth and Metamorphosis of Bullfrog Tadpoles in an Intensive Rearing System

Abstract: The effect of two levels of temperature and natural and artificial photoperiods on the growth and metamorphosis of tadpoles of the American bullfrog Rana catesbeiana were evaluated in an intensive‐rearing culture environment. Four groups of tadpoles at Gosner stage 24–25 were subjected for 50 d to four different treatments: (1) Tadpole culture with temperature control system (25.9 ± 0.34°C) and natural photoperiod of 12.25 h light : 11.75 h dark (treatment T), (2) an artificial photoperiod of 10 h light : 14 h… Show more
