Effects of environmental conditions and nutrients on the occurrence and distribution of potential harmful phytoplankton in mesotrophic water

Marudu Bay, north coast of Sabah is characterized with mesotrophic water body and typical environmental parameters throughout the year. The current study was undertaken to evaluate the effect of environmental parameters and nutrients in mesotrophic water on the occurrence and distribution of poten...
