During takeoff we received an ANTI-ICE DUCT WARNING MSG. We continued the takeoff; finished the Climb Check Checklist. Captain ran the QRH while the First Officer was pilot flying and handling the radios. First Officer called Dispatch and Maintenance Control to inform them of the situation. We were directed by Dispatch to continue to our filed destination due to weather at other airports. Captain finished the QRH and requested an altitude of 14;000 feet to get out of icing. We were able to turn off the Wing Anti-ice and keep the Cowl Anti-ice on. While descending into our destination we received and ICE DETECT MSG and turned on the Wing Anti-ice switch to STBY. The Wing Anti-ice was heating the right wing on and off during the approach phase. Captain decided for safety to declare an emergency. We were given a clearance for the ILS. We never picked up any ice during the approach phase and landing phase of flight. QRH directed us to land with flaps 20 and flaps OVRD button on. Once we decided to declare the emergency; we didn't have enough time to notify the Flight Attendant due to the workload and flight conditions. We landed safely; told ATC to secure the Fire Rescue Equipment and taxied safely to our gate. Wrote up the discrepancy in our Maintenance Log and contacted Maintenance again to confirm the discrepancy.
A CRJ-200 ANTI-ICE DUCT WARNING MSG alerted during takeoff which was continued; but after completing the QRH; Dispatch directed that the flight continue to the filed destination with Wing Anti-ice OFF. During descent an ICE DETECT MSG alerted so the Wing Anti-ice was turned ON and emergency declared while the flight landed uneventfully.
