Residents of Barangay Tinoto in Maasim, Sarangani, experienced an unexpected natural event when thousands of tamban fish, also known as sardinella, washed ashore. This occurrence, while initially perceived as a potential omen, was clarified by Sarangani’s Provincial Environment and Natural Resources Office (PENRO) as a result of an oceanographic phenomenon called upwelling.
Upwelling, a process where deeper, colder, and nutrient-rich water rises to the surface, attracts plankton, which in turn draws in small fish like the tamban. This chain reaction led to the abundant presence of tamban fish in the area, especially during their season.
The tamban fish is common in tropical and subtropical seas and includes various species like sardinella lemuru and sardinella tawilis, the latter being the only freshwater variety found in Taal Lake. This incident in Sarangani Bay mirrors similar events in other regions like the Zamboanga Peninsula and Dipolog.
While the sudden influx of fish provided a temporary bounty for the local residents, it also serves as a reminder of the dynamic and often unpredictable nature of marine ecosystems. Such events highlight the importance of understanding and respecting the intricate balance of our natural world.
