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 25hr. 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 20/30/30ppm of the three aforementioned chemicals, respectively. The authors suggest, however, that a modified formula of 20/40/40ppm will allow for an even more stable pH on future trips. © 2010 Wiley-Liss, Inc.. Source

A whale shark Rhincodon typus was found in a set-net in southern Portugal in October 2011. This was the first record for continental Europe and represents an increase of the species' known range. Upwelling events and increase in sea-surface temperatures are possible reasons for this occurrence. © 2012 The Fisheries Society of the British Isles. Source

Bull rays (Pteromylaeus bovinus) and Dolphinfish (Coryphaena hippurus and Coryphaena equiselis) were collected in Olhão (south of Portugal). These animals hosted multiple parasites, namely Caligus spp., and underwent a variety of treatments to remove them. Of all treatments tested, hydrogen peroxide showed the best results, although only concentrations above 100 ppm were effective in parasite removal. These high concentrations, however, proved to be highly toxic for the fish and led to the loss of some animals, especially those which had been handled before treatment. A total of 14 Bull rays were transported to Bolougne-Sur-Mer (France) by road and some animals were lost, which was attributed to excessive time in transit (>45 hr). In another transport, three Bull rays and 10 Dolphinfishes were moved to Stralsund (Germany) by road and air. The mechanical wounds suffered by one of the Bull rays during transport led to its death and, consequently, a deterioration of water quality in the tank containing two other conspecifics. This deterioration of water quality resulted in problems for the other two Bull rays, and one perished approximately 48 hr after arrival. The authors concluded that Dolphinfish can be transported with a low bioload for at least 27 hr, and Bull rays should not undergo transports longer than 35 hr. Special attention must be taken to injured animals, since this can lead to a decrease in water quality and consequently affect other animals in the same transport tank. © 2012 Wiley Periodicals, Inc.
