Seasonal change in body size and grazing rate on phytoplankton of the copepod Acartia hongi female were investigated in Incheon coastal waters with bimonthly sampling from April 2004 to February 2005. Seasonal distribution of A. hongi female abundance ranged from 53inds./m3 to 6,798inds./m3 and variation of gut pigment contents of A. hongi female ranged from 0.014ng․pigment/inds. to 0.766ng․pigment/inds. The grazing rate of A. hongi female ranged from 1.627n g․pigment/inds./day to 78.112ng․pigment/inds./day. The Variation of grazing pressure on phytoplankton by A. hongi female ranged from 0.17㎍Chl-a/ℓ/day to 65.74㎍Chl-a/ℓ/day and was significant with the abundance of A. hongi female. The relationship between Cephalothorax length(L, ㎛) of A. hongi female and water temperature(T, ℃) was approximately liner, where L = 923.94 - 14.54T (r2=0.96, n=60, p<0.01) and the constant(K) of gut evacuation rate of A. hongi female was positively related to water temperature(T) and the relationship was described by the equation K=0.001T + 0.0027(r2=0.82, n=18, p<0.01). Grazing rate(G, ng․pigment/inds./day) was significant with cephalothorax length, where G = 0.0023e0.0071L (r2=0.75, n=108, p<0.01).
