A study on the diversity of freshwater algae in Bueng Boraphet, Nakhon Sawan

points using a plankton net (21
seconds. In addition, the physical factors of water were determined at all samplings points.
The result showed that the transparency of water in Bueng Boraphet was 41-105 cm. The
average of water pH was 7.91-9.05, dissolved solids was 142.2-265.3 ppm, salinity was
and electrical conductivity was 211-255
identified. Chlorophyta (26 genera) was the major division which
