Tingkat Eksploitasi Ikan Endemik Bonti-bonti (Paratherina striata) di Danau Towuti

ABSTRACT: The Exploitation Rate of Endemic Bonti-bonti (Paratherina striata) in Towuti Lake. Bonti-bonti (Paratherina striata) is an endemic fish species as vulnerable species to extinction. This fish live in Towuti and Mahalona Lake the tectonic-oligotrophic lakes that are located in Malili Complex,South Sulawesi. This lake is used for various purposes i.e. hydroelectric power plant, capture fishery, navigation, ecotourism and source of water for domestic uses. This lake also supports life of endemic fish species that should be protected from decreasing population due to intensive exploitation. The objective of this research was to study the exploitation rate of Bonti-bonti as conservation efforts. The study was done in Towuti Lake from May 2006 to April 2007 using descriptive method. Utilization rate of Bonti-bonti stocks in Towuti Lake indicated an overfishing condition of male and female population. Increasing effort (units/month) of dipnet tends to reduce fishing gear productivity.
Key words: exploitation rate, Bonti-bonti, endemic fish and Towuti Lake
