Ahh i found my answer..
"There has been some confusion about NO CATCH & RELEASE. There are additional regulations pertaining to Aurora Trout under the Endangered Species Act. You are allowed to catch one (1) Aurora Trout and you have to keep it. There is no catch-&-release because of the high mortality rate of released fish. We can't have people catch-&-release 50 Aurora Trout in a day only to have half of them die. That would defeat the purpose of having any regulations in the first place. Aurora Trout are a deep-water fish, especially in August, but when brought to the surface, they don't burp out air like a Lake Trout. As a result, their internal organs get bruised or even rupture thus 50% of Aurora Trout would die if released. Also, you are catching them 50 feet deep in 50-degree water and then trying to release them in 85-degree water on the surface. They also suffer from temperature shock. "
