    Abstract

    A research has been conducted on the effect of coral reef ecosystem damage on the result of fish haul by the traditional fisherman in Siompu Island of Buton Regency of South East Sulawesi Province. This research aims: (a) to evaluate the level of coral reef ecosystem damage (the quality of coral reef), (b) to study the social economic factors affecting the society’s attitude and perception (behavior) on the coral reef ecosystem, and (c) to study the effect of coral reef ecosystem damage on the result of fish haul by the traditional fisherman in Siompu Island of Buton Regency of South East Sulawesi Province. The data studied included physical-chemical properties of seawater, percentage coral closing, coral fish abundance, diversity index and society social economic variable affecting the coral reef ecosystem damage. The method employed in coral reef observation is transecting line method and coral fish observation using visual census. The social economic data can be collected from the direct observation result in the field, result of interview and questionnaire. 1. The result of research shows that the coral reef in Tongali village waters as the research location belongs to poorly damaged to moderately damage categories with the percentage of living coral/hard coral closing of 11.63% to 30.25%. The control location, Biwinapada village can be categorized into moderately damaged to good with the percentage of living coral/hard coral closing of 31.45% to 50.81%. The coral reef ecosystem damage in the research location of Tongali village results from the human activity particularly fish capture using explosive material (bomb). Other activities that can harm the coral reef ecosystem are the use of troll, coral miner, as well as boat anchor not too dominant in the research location. 2. The Social economic factors such as education level, income level and other job opportunity correlate positively with the society’s attitude and perception (behavior) on the coral reef ecosystem. The low education level (53-68%) of respondents affects the society perception on the coral reef ecosystem, that the coral reef ecosystem is not useful, as well as has no relationship to other marine biota. 3. The coral reef ecosystem damage highly affects the fish haul by the traditional fisherman in which there is a tendency of decrease in the fish haul in the last five years of 4.30 ton (25.95%) in 2006 to 2.47 ton (14.91%) in 2010. This finding is supported by the result of questionnaire, that 100 respondents state that the fish haul decreases in both good season and bad season.
