ABSTRACT
The aim of this work was to evaluate different transport times for pacama juvenile (Lophiosilurus alexandri) previously trained to feed formulated diets. Four hundred and eighty-six pacama juveniles (2.52±0.71g) were submitted to 24 hours of fasting before transport. The animals were divided into nine plastic bags, with density of 54 juveniles in 5L of clean water for each bag after that inflated with pure oxygen and then sealed. Fish were transported for three hours and bags were open at 5, 6 and 7.5 hours after closing. For each time three replications were used. Survival was monitored for 96 hours post-transport. The longest time tested showed the lowest values of dissolved oxygen and pH, while the total ammonia was similar in the different treatments. Survival was 100% for different transport times after 96 hours. Some juveniles returned to feed 48 hours and the majority 72 hours after opening the bags, suggesting the efficiency of transport made at different times.
