Overview
Rasbora tawarensis, locally known as depik, is a critically endangered species of cyprinid fish. It is endemic to Lake Laut Tawar in Indonesia, where its population is rapidly decreasing due to ecological disturbances, global warming, introduced species, unlawful fishing practices, and pollution.
Rasbora tawarensis faces severe threats from habitat degradation around Lake Toba, Sumatra, where agricultural expansion and urban development have altered water quality and flow patterns. The species' extremely restricted range makes it particularly vulnerable to localized environmental changes, while introduced species may compete for resources or prey on juveniles. Water pollution from agricultural runoff and domestic waste poses additional risks to this endemic lake fish.
Habitat
This endemic species inhabits the freshwater systems of Lake Toba and its tributaries in North Sumatra, Indonesia. It typically occurs in shallow, vegetated areas of the lake and associated streams with clear, well-oxygenated water.
