The video clip above shows a Risso’s dolphin at Taiji Whale Museum, getting a tube pushed down its throat. Tubing is a procedure the aquarium uses for hydration. In the wild, dolphins and other cetaceans get the proper hydration from the fish they eat. However, in captive environments, they are fed frozen fish that have been defrosted. This process removes almost all of the water that was originally in the fish.
While this procedure doesn’t necessarily hurt the dolphin, they certainly do not like it. A marine mammal veterinarian currently working for PETA stated, “It is likely uncomfortable to the dolphin, and can cause irritation to the esophagus or introduce unwanted pathogens if not performed correctly. Tubing is another in a long line of unnatural procedures imposed upon animals like dolphins and whales who are kept in captivity — a health risk in and of itself — out of necessity to help keep them alive in a foreign environment unsuitable to their long-term well-being.”
Please, DO NOT buy a ticket to any dolphin show because this is what you are supporting. Captive cetaceans can only be saved if international demand for captive entertainment ends.
