Some phytoplankton of Tamshui River from Kuantu to Shetzu

The Tamshui River is the largest river in northern Taiwan. It opens by a small mouth at Tamshui into the Taiwan Strait and pours wastes from sewage, industry and the street water of Taipei City, along with the sandy waters from upper mountainous areas into the sea. Salt water during high tide reaches the edge of Taipei City. At this time, marine plankton is easily mixed with the freshwater biome. In order to know which algal species have invaded into the estuary region of the Tamshui River, the author made a short cruise from Kuantu to Shetzu on the afternoon of July 18th, 1965 around 3:00 P.M. at the time when the tide from the sea was rising. In this collection, a small plankton-net was towed by a small vane-boat horizontally just beneath the surface, at that time a breeze was coming in from the sea.
