We examined the reproductive potential of the anchoy, Engraulis japonicus, based on the data of adult maturation and the feeding envitonment in the southeastern and southwestern coastal waters of the korean Peninsula during early spawning season of 2006-2009. Salinity and Chlorophyll a concentration displayed significant yearly and regional differences. The mean densites of the copepods, gonad somatic index , and condition factro of the anchovy were higher in 2008 than in 2006, 2007 and 2009 . GSI and CF were higher in the southwestern area than in the southeastern area.
