Strenuous exercise in fish is usually a consequence of migration, reproduction, and spawning. Varying among fishes, this kind of stress is associated with blood glucose and lactate increase, in relation to which two major groups are distinguishable: the "lactate releasers" and "non-lactate releasers". Unlike strenuous exercise, sustained swimming imposes a variety of effort that results in distinct kinetic types of blood lactate and glucose. Compared to Platichthys stellatus and Oncorhynchus mykiss, blood lactate of Salminus maxillosus (dourado) was lower after exercise, whereas recovery time was greater. Great demands were made of white muscle, and dourado is not a lactate releaser. Two different metabolic tendencies were observed in sustained and intense swimming. Gluconeogenesis was observed during recovery, as well as the alanine cycle which recomposes the lactate tissue pattern. Full recovery after intensive exertion required more than 24 hours. |
