Kabibe pa more! Giant clams now cleaning Batangas town waters

Oct 3, 2016 @ 19:39

Expect the seawaters of Calaca town, Batangas to be cleaner thanks to the transfer of 50 giant clams (Tridacna Gigas) which are capable of filtering marine pollution.

This was stressed by Semirara-Calaca environment project director Dr. Ronnie Estrellada.

The 50 giants were taken from Semirara, Antique and placed in Calaca waters.

Giant clams are a known filter specie who sip sea water from the surface and filter planktons for food and release clean sea water back to the surface.

By the same process, they can also clean polluted sea water.

Estrellada said the sites where they were stocked served as shelter areas and spawning grounds for all marine organisms. This establishes a symbiotic relationship with the coral community.

Likewise, they become feeding grounds for fishes because their waste materials – epiphytes (plants that grows harmlessly upon other plant and derives the moisture and nutrients from the air, rain, and sometimes from the debris accumulating around it) and algaes (lumot)-attach on the shells and serve as food for juvenile fishes and other crustaceans, corals.

He said the original stocks of giant clams came from Bolinao in Pangasinan in 2006.
