This study aims at comparing two data bases related to occupational injuries in the French sea fishing industry: a data base created between 1977 and 1980, a data base created between 1996 and 2001. These bases were made from report forms filled out by fishermen after an accident. The study focuses on the accidents occurring when the vessel is in the process of fishing. In the 1980s, as well as today, the processing of fishing gear seems to be a very dangerous task, correlated with the risk of being "struck by, swept along, pinned" by the elements of the rigging and the risk of serious injuries. The processing and handling of the catch also cause a large amount of accidents; during these tasks, fishermen have to cope with two main risks: being "cut or pricked" and making an "excessive effort, awkward movement". Rate and features of occupational accidents do not show notable evolution. These findings lead us to question the different prevention measures implemented in France during the last few decades and to propose new prevention direction.
