Most studies on the occurrence of MSDs involving fisherman were done on vessels. Swedish studies on fishermen have shown that symptoms from the musculoskeletal system were common, and that they follow a logical pattern according to the fishing and type of working tasks on board. Among the small scale coastal fisherman studied, seventy-seven per cent experienced symptoms of the musculoskeletal system during the previous 12 months of the survey, 61% low back pain and 37% shoulder pain. The largest number of fishermen considered the motion of the vessel to be a major strain, not only on the musculoskeletal system, but on the individual as a whole (Törner et al., 1988). A higher prevalence of symptoms of the upper limbs was found among those with jobs involving high repetitiveness or forceful movements, as compared to those who had jobs with low repetitiveness and low-force movements.
