Meanwhile Robin Sowden Taylor, Scott Morgan, Darren Allinson, Dai Flanagan and Sam Norton Knight have all departed the Blues to pursue their rugby careers elsewhere. Darren Allinson joined London Irish, Flanagan joined the Ospreys while Sam Norton Knight has signed with Sanyo Wild Knights in Japan.
Robin Sowden Taylor and Scott Morgan are looking to finalise contracts with other clubs over the forthcoming weeks while Blues Backs coach, Billy Millard, has also left to take up a teaching post in Adelaide, Australia.
Director of Rugby, David Young said, "Everyone at the Blues would like to thank the players for their contribution, both on and off the field, over the past few years."
"They have all played their part in moving the region forward and we wish them the best of luck with their rugby careers."
"We look forward to welcoming the new players to the squad and build on the foundations we laid last season."
"Lifting the Amlin Cup in the South of France was an incredible highlight for our fans and everyone involved at the Blues, and we truly appreciate their support throughout the ups and downs of the whole season."
"As we look to build on these achievements next season, the loyalty of our supporters remains of huge importance to the players and the rest of the Blues team, and vital to our success on the pitch."
