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

Abstract

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
