Tawilis is the only freshwater sardine native to the Philippines, renowned for its nutritional value and delicate flavor. This infographic highlights key facts about Tawilis, including its habitat, lifecycle, and significance in local cuisine. Discover why protecting this unique species is crucial for biodiversity and sustainable fishing practices.
What is Tawilis?
Tawilis is a small freshwater fish species native to Taal Lake in the Philippines. It is the only known freshwater sardine in the world, scientifically named *Sundasalanx tawilis*.
This fish is a vital part of the local ecosystem and economy due to its unique habitat and limited distribution. Tawilis is highly valued for its nutritional content, rich in protein and omega-3 fatty acids. Conservation efforts are crucial as overfishing and habitat degradation threaten its population.
Unique Habitat: Taal Lake
What makes the tawilis unique in the aquatic world? Tawilis is the only freshwater sardine species found exclusively in Taal Lake, a volcanic caldera lake in the Philippines. Its habitat's isolation contributes to its distinct biological characteristics.
Why is Taal Lake vital for tawilis survival? Taal Lake provides a unique freshwater environment with stable temperature and nutrient levels essential for the growth and reproduction of tawilis. The lake's volcanic origins create a specialized ecosystem supporting this rare fish species.
