In this study, I examined the water quality and phytoplankton community in aquaculturelaver farm in the southwest part of Aphae-do, South Korea, based on the young leaf stage,middle leaf stage, and adult leaf stage of laver thallus from October, 2013 to January, 2014. It wasobserved that the Aphae laver farm, as located in shallow waters, was found to have a seriousresuspsension of the surface sediments due to physical disturbance caused by winds and tidalmixing. Such a resuspension of surface sediments coupled with nutrients supply obstructs lightpenetration into the sea for its huge amount of total suspended matters. As a result for this reason,it was viewed toimpedthe growth of phytoplankton was impeded as it also competes with laver toabsorb the same kinds of nutrients as laver does during the laver growth period in winter. Suchelements of the marine environment in Aphae laver farm are in contrast with the environment ofJapan, where nutrients including dissolved inorganic nitrogen, in particular, are insufficient tocause the recent laver bad harvest, discoloration and quality degradation while large diatoms,with their higher nutrients absorption efficiency than laver, generate winter red tide. In otherwords, an important factor to maintain the high laver production in the southern parts of WestSea of Korea was found to be the marine environment of its laver farms where large diatoms areprevented from growing due to nutrients supply and dense seston weights from resuspendedmatters by physical disturbances.
