Long-term transportation, by road and air, of chub mackerel (Scomber japonicus) and atlantic bonito (Sarda sarda)

During the second semester of 2009, three trips were made from Olhão (Southern Portugal) to Stralsund (Northern Germany) carrying 2.122 animals, which included multiple teleosts, elasmobranchs and invertebrates. This group included scombrids, such as 1.869 Scomber japonicus and 9 Sarda sarda, which are notoriously difficult to transport. However, multiple adaptations to transport regimes adopted regularly have allowed the authors to successfully move these animals by road and air over a total of up to 25 hr. Such adaptations included maintaining oxygen saturation rates at approximately 200%, and also the constant addition of AmQuel®, sodium bicarbonate, and sodium carbonate. Different formulations were used during the three trips, with the best results corresponding to 20/30/30 ppm of the three aforementioned chemicals, respectively. The authors suggest, however, that a modified formula of 20/40/40 ppm will allow for an even more stable pH on future trips. Zoo Biol 30:459-472, 2010.
