shark tank and a seal exhibit. Controversies One of the original co-owners of the Portland Aquarium, Ammon Covino, was arrested on February 21, 2013, in Boise, Idaho, on charges of illegally harvesting marine animals. He later pleaded guilty to conspiring to illegally obtain sharks and rays from the wild in Florida and was sentenced to a year and one day in prison. In October 2015, he was rearrested for allegedly violating terms of his two-years of supervised release by getting involved again in the family aquariums. At least two senior employees of the Portland Aquarium, including a veterinarian, quit their jobs at the aquarium citing concerns about how the animals were being treated. Along with this, a former employee from the Portland aquarium showed to The Oregonian a death log of animals that had died in the aquarium from February 18 to May 16, 2013. The death log contained over 200 animals that died during that time, causing much controversy and making the Oregon Humane Society launch an investigation to the aquarium. The aquarium has been subject to citizen protests at the site.
