    Raft system was practiced for mediterranean mussel (Mytilus galloprovincialis) culture in Sinop Region, Black sea. Four different types of collectors (A type collector was in 14 mm diameter nylon rope which is suspended from the the raft in known mussel settlement time. B type collector was in 14 mm diameter nylon rope which is suspended one month early from the known mussel settlement time. C type collector was in 22 mm diameter and made from old ship rope. D type colllector was in 19 mm diameter and made from old anchovy net) was conducted to investigate, effect of collector type on settlement. The results showed that collector types had a significant effect spat settlement. Both shape and surface structure of the collector was found significant (p<0.05). The filementous and thready surfaces of C and D type collectors were prefered by spats for initial settlement. D type collector had a highest density with 6.37 +/- 0.60 ind cm(-2). At the end of 8 months experimental period, the number of spats on A, B, C and D type collectors were found as 1218 +/- 7.90, 1344 +/- 6.80, 3480 +/- 5.10 and 3800 +/- 5.40 ind m(-1), respectively.
