Use of salt during transportation of air breathing pirarucu juveniles (Arapaima gigas) in plastic bags

Previous study demonstrated that transportation of pirarucu juvenile in plastic bags is a suitable procedure, although it stimulated some stress responses. Therefore the objective of this study was to investigate the addition of salt as a stress mitigator in pirarucu juveniles during transportation in plastic bags. Fish were reared for a month in earthen pond and held in 3 indoor 2000-L depuration tanks for 24 h to allow complete gastrointestinal evacuation, then placed in 30-L polyethylene bags with 10 L of water at a density of 12 fish/bag (40 g/L) with different table salt (NaCl, 97%) concentrations in the water: 0, 1, 3, 5 g/L (3 replicates each concentration). Transportation took 3 h and afterwards fish were transferred to 1-m3 floating cages installed inside an earth pond for recovery. Fish stress responses were evaluated before, during and after transportation procedure, and the analyses performed were: cortisol, glucose, lactate, haematrocrit and waterborne net Na+, Cl-, K+, and Ca2+ fluxes. No mortality was recorded in any treatment during transportation and recovery periods. Cortisol exhibited an increase after transport with 1 g salt/L and at 24 h after transportation for all treatments showing a latency period in their response. Glucose exhibited a similar pattern for all treatments with a significant increase before and after transportation, returning to basal levels in 24 h. Lactate concentrations increased before transportation and after transportation, presenting a significant decrease in all treatments. Addition of salt in the transport water increased Na+, Cl- and Ca2+ net fluxes in pirarucu. Using salt during pirarucu juvenile transportation should be avoided since there is no reduction on stress responses and causes osmoregulatory disturbances. © 2006 Elsevier B.V.

The farming of the Amazonian air breathing fish, Arapaima gigas, has been growing substantially over the last decade in Brazil and other South American countries.
