Long-term transportation of juvenile pacamãs Lophiosilurus alexandri at different densities

This study aimed to evaluate the effects of long-term transportation of juvenile pacamã at different densities. The transportation lasted 11 hours at densities of 40, 55, and 70 juveniles (2.1±0.6 g weight) per bag containing 8 L of water. The different densities did not affect the water quality par...

Description
Summary:This study aimed to evaluate the effects of long-term transportation of juvenile pacamã at different densities. The transportation lasted 11 hours at densities of 40, 55, and 70 juveniles (2.1±0.6 g weight) per bag containing 8 L of water. The different densities did not affect the water quality parameters and the survival rate immediately after transportation was 100% for all treatments. However, after 24 and 48 hours, higher mortality was found for juveniles transported at the greatest density. Transportation for 11 hours can be undertaken using a density of up to 55 juvenile pacamã individuals/transportation bag.
