Why are sculpins banned as bait in some states?
Some states banned the use of sculpins as bait after it was discovered that sculpins in some waters were infected with a parasite similar to the whirling disease parasite. This parasite did not look exactly like the whirling disease organism, but was close enough to cause concern, especially since people were collecting these sculpins from waters where the whirling disease parasite was known to infect trout.
