(Portland, OR)  --  The U.S. Attorney in Oregon continues a crackdown on poaching of bull trout.  The office says 31-year-old Tyler Warren from Pendleton has been sentenced to three years federal probation, a thousand dollar fine, 40 hours community service, and he's banned from fishing for three years.  Warren pleaded guilty to catching bull trout from the Metolius River and keeping them.  He is the fourth Oregon resident convicted in federal court for illegally taking bull trout, which are listed as a threatened species and an important Tribal resource.
