Lack of protective effect from OHS may be related to low participation rate (13.8%) and ineffective implementation of the service indicated by: 1) workplace safety check was conducted only at 62 workplaces (23.8% of all OHS members); 2) fishers are a small customer group for OHS, and no customized services or materials have been specifically designed for them as part of the OHS programme [14]; and 3) education for fishing experts acting as OHS consultants has been conducted only in a limited manner. All of these suggested reasons stem from commercial fishers being a small OHS client population. An OHS centre might have only few or even just one fisher as a customer, which hampers accumulationof experience concerning the special needs of a service targeting the fishers [14].
