Sir Joel, is it possible to create aquaponics using the seawater here in the Philippines?
You can use salt-water-fish and seaweed instead. But the aquaponic principle is the same as in fresh water-using fresh water plants and fresh water fish. In seaweed aquaponics you use salt water fish, and seaweed( which obviously is a salt water plant). I have not tried it yet but in some countries they have.
