What do you mean? Thats what ODFW calls them probably since they use them for breeding purposes, hence the word Brood/Brooder.. Here's a quote from ODFW site
Large brood trout were released this week in Huddleston Pond in Yamhill County. The fish are 4- and 5-year-old rainbow trout from ODFW’s Roaring River hatchery and range in size from 8 to 18 pounds.
