Highlights

• Transport of Amazonian ornamental fish under hyperoxic conditions
• Antioxidant and oxidative damage responses under transport conditions
• Lipid peroxidation remained, irrespective of transport time or initial oxygen concentrations
• Fish (
  Peckoltia oligospila
  ) can be safely transported in plastic bags.

ABSTRACT
It was analyzed antioxidant competence and lipid peroxidation in juveniles of

Peckoltia oligospila

submitted to transport in plastic bags under different concentrations of dissolved oxygen for up to 24 h. Oxidative balance of fish transported for 3, 6, 12, and 24 h in normoxic (NX), moderate hyperoxia (MH), and severe hyperoxia (SH) was evaluated. For this, it was determined the total antioxidant capacity against peroxyl radicals (ACAP) and lipid peroxidation levels (TBARS) in liver, gills, muscle, and brain. After 24 h and, regardless of water quality, dissolved oxygen concentrations, and duration of transport, no mortality occurred for any of the treatments. The antioxidant competence of P. oligospila in the different organs remained high, except for some occasional decrements. Because of this, TBARS concentration remained low in the different organs, irrespective of transport time or initial oxygen concentrations. According to the results, P. oligospila antioxidant system was efficient enough for the prevention and/or suppression of products derived from lipid peroxidation. Therefore, the oxidative status was not severely affected in the assessed organs over transport time in hyperoxic conditions. Furthermore, Peckoltia oligospila can be safely transported in plastic bags without an extra supply of oxygen for up to 24 h, since survival was not affected.

Too bad the summary does not explain what is severe hyperoxia. After all, it is common, at least in Europa, but I think everywhere to transport fish under pure oxygen.

Then it is interesting to know hyperoxia does not hurt, in fact the title did make me realize animals have antioxydants in their body, and therefore putting them under pure oxygen can, potentially, hurt.

And it is nice to know, although experience has taught a lot, no measurable effects can be found.

Is it not visible at the original source link? Unfortunately, since I'm on campus, it may be visible to me but I can't tell if it's blocked to the general public.

Thanks Lee.

Cheers, Eric

Hi Eric,
At the original source it is available to those who are "members", otherwise it is set as a pay for view situation.
The link that I provided is an open access area put on by the authors.

As I figured. Thanks again, Lee.
