2011년 2월부터 5월까지 경남 남해군 연안에서 소형 Beam trawl에 채집된 문치가자미 치어 이석을 관찰 분석하여 부화시기와 초기성장을 추정하였다. 문치가자미 치어는 2011년 2월에서 5월까지 총 175개체가 채집되었며, 체장-체중 관계식은 $W=9.76^*10^{-8}L^{4.39}$ ($r^2=0.93$)를, 체장-이석경 관계식은 L=0.0795R+0.2249 ($r^2=0.92$)로 추정되었다. 체장 성장은 $L_t=135{exp}{-{exp}[0.0103(t-116)]}$ ($r^2=0.83$)로 Gompertz 성장식이 가장 유의하게 회귀되었다. 이석 일령으로부터 추정한 주 산란시기는 12월에서 1월인 것으로 추정되었다.
Hatching date, main spawning period and growth of juvenile marbled flounder (Pseudopleuronectes yokohamae) were determined by analysis of microstructure in otoliths. Marbled flounders were collected by a small beam trawl in Namhae from February 2011 to January 2012. The length (L, mm) was related to body weight (W, g); $W=9.76^*10^{-8}L^{4.39}$ ($r^2=0.93$). The length was also related to otolith radius (R, ${mu}m$); L=0.0795R+0.2249 ($r^2=0.92$). The growth in length was represented by Gompertz growth curve; $L_t=135{exp}{-{exp}[0.0103(t-116)]}$ ($r^2=0.83$). The hatching date calculated from the number of daily growth increments in otoliths was between mid-December and mid-February.
