This study is to find out the effects of various iron concentrations on growth, feeding and feed efficiency of olive flounder, Paralichthys olivaceus. The growth rate, feeding rate and feed efficiency of olive flounder in each experiments were represented by the relative value. The relative growth rate and relative feed efficiency of olive flounder were kept almost constant below the iron concentration of 1.0 mg/l, but were significantly decreased above the 5.0 mg/l iron concentration. The growth rate, feeding rate and feed efficiency of olive flounder exposed to 10.0 mg/l iron concentration were significantly decreased than that exposed to normal condition. From these results, it could be concluded that the high level of 5.0 mg/l iron concentration in the bottom water would curtail production of olive flounder in coastal area.
