Karl Oystein Oyehaug, chief finance officer of Atlantic Sapphire, tells New Times the salmon are raised in optimal conditions, where they're safe from wild fish diseases and maintained with water temperatures and currents similar to their natural habitats, keeping them healthy. But a series of mass mortality events at the Bluehouse over the past year has led a nonprofit group to question how safely the fish are actually kept. In an April 21 letter addressed to two state agencies that oversee farming and animal-cruelty complaints, animal-rights advocates from the nonprofit organization Animal Outlook outlined a series of incidents at Atlantic Sapphire's Homestead facility wherein a total of 800,000 salmon died prematurely and, according to the advocates, were subjected to unnecessary cruelty by the company.
