Abstract

Juvenile big bellied seahorse Hippocampus abdominalis were exposed acutely and chronically to elevated ammonia and nitrite {24 h exposure: 0·01, 5·0, 10·1, 14·8 and 19·9 mg 1 -1 total ammonia-nitrogen [TA-N] and <0·001, 74·4, 99·2 and 123·6 mg 1 -1 [NO 2-N] nitrite-nitrogen and 35 days exposure: 0·11, 0·55, 1·67 and 3·07 mg 1 -1 TAN and <0·001, 0·92, 4·67 and 9·10 mg NO 2-N 1 -1}. Significant (P<0·001) increases in oxygen consumption rate and ventilation frequency occurred at 14·8, 19.9 mg 1 -1 TA-N and 99·2, 123·6 mg 1 -1 NO 2-N for acutely exposed fish. Oxygen consumption rate was significantly (P<0·05) elevated at 1·67 and 3·07 mg 1 -1 TA-N in chronically treated fish and ventilation frequency increased significantly (P<0·05) at 0·55, 1·67, 3·07 mg 1 -1 TA-N and 4·59, 9·10 mg 1 -1 NO 2-N. There were no significant differences in growth between controls and ammonia exposed fish. Mortalities occurred at 14·8, 19·9 mg 1 -1 TA-N. © 2001 The Fisheries Society of the British Isles.
