Abstract

The inshore fisheries resource is important to the health and culture of many of the inhabitants of Pacific Island countries (PIC). Ciguateric fishes (mainly demersal reef fishes) cause a range of distressing and often debilitating gastrointestinal neurological and cardiovascular disturbances. Consequently, ciguatera limits the utilisation of this otherwise over-exploited resource. For many victims, the symptoms suffered during the chronic phase of ciguatera (lasting weeks, months and occasionally years) are exacerbated upon consumption of certain foods, particularly non-toxic fishes. After each outbreak, victims and members of their social-network experience a transient increase in perception of the risk of eating reef fish. The impact of ciguatera is greatest in atoll island countries where fish is the primary source of protein (it also has a major impact and to facilitate the management of ciguatera in PIC, regular information is required that quantifies: (i) the true incidence of ciguatera; (ii) the extent and way in which different communities avoid ciguatera; and (iii) the adverse impact ciguatera has on health, the workforce, trade and tourism. Over the last 15 years (based on SPEHIS data to 1990), some countries recorded a decrease in the ciguatera problem (New Caledonia, Marshall Is.), other countries an increase (Kirbati, Tuvalu, French Polynesia), while still other countries recorded an increase followed by a decrease in ciguatera (Tokelau, American Samoa, Western Samoa, Fiji and Vanuatu). There may also be seasonal trends in the incidence of ciguatera in some countries e.g. Fiji. Management options presently implementable in PIC include: (i) treatment with i.v. mannitol; (ii) provision of timely advise on the location and status of ciguatera "hot spots" in each country that would allow affected communities to react objectively to the risk posed by ciguatera; and (iii) modification of human behaviour and aspirations to reduce the impact of increasing population, pollution and development (e.g. causeways) pressures.(ABSTRACT TRUNCATED AT 250 WORDS)
