Intermittent sustained swimming in 'matrinxã' Brycon amazonicus (Bryconidae: Bryconinae): hematological and metabolic responses [PDF]
Neotropical Ichthyology, 2013 In fish, studies on a wide variety of physiological effects of exercise have been reported since a long time. It has been attributed special attention to some types of exercise, however, its application as a healthful practice in the rearing and welfare ...
