The whales and dolphins at Vancouver Aquarium just can't seem to catch a break. Even the city's new bylaw that bans breeding and introduces new, independent public oversight of the Stanley Park attraction won't offer much relief for the captive cetaceans. Because, as it turns out, there never was a bylaw after all.
In 2005, the Vancouver Aquarium sent five harbour seals to Marineland Canada and they suffered in the poor conditions. I was one of the employees who received them. Maintaining balanced water chemistry was always a challenge for the maintenance employees, and dangerous spikes in chlorine and ozone off-gas levels were common. One particular incident claimed Pepper the harbour seal's life. Her suffering and subsequent death I recall vividly.
