     Abundance of anchovy in the South eastern Sea of Korea was estimated by  the 
echo  integration in  March and  Novemver 1995.  Acoustic  survey was  carried out 
during daytime  along the transect  line, echo-sounder operating  at 38kHz was  used 
for detecting anchovy school.
     From midwater trawl hauls  for species identification, composition of anchovy of 
all hauls in the surveys were composed of 87.4% to 91.3#% of the total catches. Total 
body length were ranged from 7.1cm to 15.4cm.

     The mean relative  abundance in the survey  areas were 9.2 ton/n.mile2  and 6.4 
ton/n.mile2, respectively in  March and November. Geostatistic method was  applied to 
the variance estimation.
