Fish losses at hatcheries are a normal thing, like it or not. Systems sometimes fail. Then backup systems sometimes fail. And even backups to the backup can sometimes fail. Hatchery owners, including WDFW, employ many measures to reduce the frequency of fish losses, but as far as I know, no one have ever figured out how to eliminate losses entirely. It's a part of the fish rearing business, and it's among the reasons fish culturists never put "all their eggs in one basket." The risk is spread around: multiply incubators, multiple fry starting systems, multiple rearing ponds, and even multiple hatchery facilities. Fish losses cannot be prevented, but the frequency and severity of loss can be reduced. I'm pretty sure this is what WDFW does. Anyone who simply cannot tolerate loss of hatchery fish should not be in the hatchery business.
