Surveys for parasitic barnacle, Heterosaccus dollfusi Boschma, 1960, on crab, Charybdis longicollisLeene, 1938, were conducted monthly between July 2002 and June 2003 along the coast of Iskenderun Bay. A total of 857 crab specimens were captured in 6 localities at different depths (4 to 50 m). Parasites were detected in the abdomen of 200 out of 425 females. Parasite infection rate among females was 47.6% whereas the rate was 23.31% for the total. Captured crabs ranged from 0.6 to 50.75 g (WW) in weight, while their carapace length varied between 19.2 and 67.3 mm (CL). The infected crabs varied from 2.1 to 24.3 g (WW) in weight and between 28.4 and 52.8mm (CL) in length.
