As of 12-18-2016 Kraken has delisted all DAO pairs. No balances were affected and any open orders at the time have been closed. There will be a period of time to withdraw your DAO if you wish. Any DAO you don't withdraw will be automatically converted to ETH at the rate of 1 ETH per 100 DAO. We'll send an email to everyone with a DAO balance explaining the details.
