Effects of climate scenarios on the growth and physiology of the Amazonian fish tambaqui (Colossoma macropomum) (Characiformes: Serrasalmidae)
This study evaluated the effects of three climate scenarios predicted by the Intergovernmental Panel on Climate Change for 2100, on the growth and physiology of the tambaqui (Colossoma macropomum). Juveniles of tambaqui were reared in four rooms (current conditions, and the climate scenarios B1, A1B...
