the seawater and suffocating the fish. Huang Zilun says driftwood has choked tidal pools with wood chips. Taitung Fisheries Research Institute, Huang Zilun: "The fish underneath can't survive, because they have no air and lack oxygen. We tested the dissolved oxygen, and it's generally down to 2 or 3, which is very low." Fish popualation suffers Comparing samples from the same area before and after the typhoon, the researchers have found that the fish varieties and populations have ...

the dive, a diver usually moves underwater by swimfins attached to his feet, but external propulsion can come from an underwater vehicle, or a sled pulled from the surface. Water normally contains dissolved oxygen from which fish and other aquatic animals extract all their required oxygen as the water flows past their gills. Humans lack gills and do not otherwise have the capacity to breathe underwater unaided by external devices.[3] Some experiments indicate the possibility of filling ...

FSLF Kids conduct water quality testing on a regular basis. They test for turbidity, PH and dissolved oxygen. It' sa very simple screening test which gives an indication of water quality - poor, fair or good. In Part 1, we see some FSLF Kids take a paddle boat about 20 meters from the shore to get their water samples. These are brought back to the lakeshore where testing is done. See Part 2.
