Rockfish, Sebastes sxchlegeli (total length; 10.36±0.49㎝, tital weigth; 16.38±1.86g N;290) were epised to various concentrations of naphthalene for 28 days Exposure concentrations of naphthalene established contol, ethanol (so/vent)control, 0.5, 1.0, 1.5 and 2.0㎎, Nap L-1, After exposure, We observed survival rate, and degree of tissue (DTC) in gill under optical microscopy Survival rate the rockfish was more than 90% in control, ethanol control, 0.5and 1.0㎎ Nap L-1, whereds it decreased in 1.5 and 2.0㎎ Nap L-1, (respectively 80%, 62.2%).ln histological observation stasis, aneuruysm and necrosis showed dose dependent on, Whereas, DTC at rusion of gill lamellar lamellar telangiectasia and stasis obsetbed at more more 1.0㎎ Nap L-1, and aneurysm and necrosls at more 1.5㎎ Nap L-1, These resuylts showed naphthalene caused survival and severe change t0 the gill of the rockfish which was relatedto ewposure concentration.
