  5. Fermented Tawilis:
    • Bagoong: Tawilis can be fermented to make a Filipino condiment called “bagoong.” The fish is salted and allowed to ferment, resulting in a salty and savory product often used as a dipping sauce or ingredient in Filipino dishes.

Remember to adjust seasonings and cooking times based on your taste preferences and your specific cooking method. Always ensure that the fish is cooked thoroughly before consuming it. Additionally, local culinary traditions and personal preferences might result in various creative ways of preparing tawilis, so don’t hesitate to experiment and try new recipes!

Conservation Status of Tawilis

In 2019, the International Union for Conservation of Nature (IUCN) listed the tawilis as endangered. This means that the population of tawilis has declined by at least 50% over the past ten years. The main threats to the tawilis are overfishing, illegal fishing, pollution, and habitat degradation.

Overfishing is the biggest threat to the tawilis. Fish are caught using various methods, including nets, traps, and spears. The use of illegal fishing gear, such as motorized push nets and ring nets, is also a problem. These nets can catch large numbers of fish, including young fish that have not yet had a chance to reproduce.

Another threat to the tawilis is pollution. The lake is polluted by agricultural runoff, industrial waste, and sewage. This pollution can kill fish and make the lake less hospitable to them.

Habitat degradation is also a threat to the tawilis. The lake’s water levels have been declining due to climate change and water extraction, reducing the amount of habitat available for the fish.

Several things can be done to help conserve the tawilis. These include:

  1. Reducing fishing pressure. This can be done by setting limits on the number of fish caught and enforcing fishing regulations.
  2. Eliminating illegal fishing can be achieved by increasing law enforcement and educating fishermen about the importance of sustainable fishing practices.
  3. Reducing pollution. This can be done by reducing agricultural runoff, industrial waste, and sewage.
  4. Protecting the lake’s habitat. This can be done by reducing water extraction and restoring the lake’s degraded areas.

The tails are an important part of the Philippine culture and economy. By taking steps to conserve them, we can ensure that this fish will continue to be a part of our lives for generations to come.

Conclusion

Tawilis is a unique and delicious fish that offers numerous health benefits. Its high protein content and essential vitamins and minerals make it an excellent choice for maintaining overall health. Whether consumed fresh or in various prepared forms, Tawilis can be a nutritious addition to your diet.

However, as with any food, moderation is key. While Tawilis has many advantages, excessive consumption may lead to mercury accumulation in your body due to its habitat. Therefore, it’s recommended that you consume Tawilis in moderation and ensure you source it from reputable suppliers.
