ABSTRACT

This study evaluated the effects of curimbata Prochilodus lineatus transportation in three densities (100, 150 and 250 g L -1 ) on survival, metabolic, ionic and hematological (red series) variables. Curimbata juveniles were transported in plastic bag during six hours, and sampled before packing, immediately after the arrival, 24 and 96 hours after transportation. During recovery, higher mortality was seen in fish transported in the highest density. Water variables, such as conductivity and total ammonia, presented increased values as density increased (p -1 density induced the highest mortality rate and the worst variables values measured. 96 hours of recovery after the stressing event was enough to return to initial values for hematological variables, but was not sufficient to return to initial values for metabolic and ionic variables.
