dc.description.abstract | We evaluated the efficiency of chemical marking of black rockfish scales by immersion in oxytetracycline hydrochloride (OTC), alizarin red S (AS) and calcein (CAL) diluted rearing water. Immersion treatment of chemicals had no effects on both mortality and growth of black rockfish. Marking success was 100% in all treatment durations (24, 48, 72 hours.). Marking retention rates at 24 weeks after treatment were 100% in OTC and CAL treated group, but marking quality was higher in CAL treated group (brilliant 92%, bright 8%, dim 0%). Than in OTC treated group (brilliant 4%, bright 70% and dim 26%). AR treated group had lower marking retention rates and marking quality than OTC and CAL treated group. As a result, immersion treatment with OTC and CAL was effective in marking scales of fish and practical in releasing program.n both mortality and growth of black rockfish.
