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.
