.— Subadult tiger shrimp Penaeus monodon (30.15 ± 2.19 g) were exposed individually in sea water of 25%o to 0 (control), 1.11, 4.76, 10.06 and 19.09 mg/L copper for 24 h. Hemolymph pH, PO 2 (partial oxygen pressure), PCO 2 (partial carbon dioxide pressure), HCO 3 , oxyhemocyanin and protein levels were determined. Hemolymph PO 2 increased, whereas hemolymph pH, PCO 2 , HC0 3 ‐, oxyhemocyanin. protein and the ratio of oxyhemocyanidprotein levels decreased with increasing concentrations of ambient copper in the range of 1.11 to 19.09 ma/L. It is concluded that P. monodon following 24‐h exposure to ambient copper as low as 4.76 mg/L shows a reduction of oxyhemocyanin, protein, and the ratio of oxyhemocyanin to protein, and develops metabolic acidosis in the hemolymph.
