Turunen, 22, has signed from Swedish Division 1 side Asploven, where he scored a goal and four assists in 15 games, after advice from former Basingstoke Bison defenceman Mikko Purontakanen.
After spending all of his junior career with his home town JYP Jyväskylä he made the step into professional hockey last season with 41 games for SaPKo Savonlinna in the Finnish Metsis Division, one below the the top league in Finland, where he scored a goal and seven assists.
Turunen becomes the third Finnish player to ice for the Stingrays after Pasi Raitanen and defenceman Jani Virtanen last season.
He will make his debut in this weekends games against the Coventry Blaze and at home to the Newcastle Vipers on Sunday.
Stingrays coach Rick Strachan had this to say about the signing:
"Curtis Cruickshank spoke to Mikko Purontakanen who he played with in Basingstoke last season. He told him we were looking for a 'D' and he recommended Antti. He is young, he skates well and is aggressive. He is another body, another pair of legs and I hope he can make a contribution to the team."
