Abstract
Live fish transport is among the most commum procedures in fish farming. It is
a stressful procedure, responsible for several physiological and metabolic responses
caused by a series of stimulus that can lead to significant losses. The aim of this work
was evaluate stress responses of juvenil of pintado (Pseudoplatystoma corruscans)
transported for 12 h in a closed system. A total of 60 fish (66.6 ± 18.3 g; 24.2 ± 2.2 cm)
were used. Samplings were performed at arrival (0 h), 24, 48, 72 and 96 h after
transport. Blood cortisol levels did not show significant differences but there was a clear
profile of increase after transport and gradual reduction after the procedure, reaching
levels below the control levels at 48, 72 and 96 h. Glucose was elevated after transport
returning to control levels within 72 h. Muscle lipid increased after transport and
returned to control levels within 72h. Serum triglicerid did not alter folowing a clear
profile and cholesterol and protein increased after transport. Regarding ionic indicators,
chloride levels decreased after transport, as well as hematocrit, number of erythrocytes
and hemoglobin.
Key-words: Transport, pintado, cortisol, glucose, protein, lipids.
