| Abstract: | The 168-h LC50 values of un-ionized ammonia (NH3-N) was tested to be 5.40, 1.80, 0.65, 0.64mg/L and the EC50 (concentration causing 50 percent reduction in tolerance of hypoxia) values was 0.44, 0.23, 0.24, 0.12 mg/L for juvenile and adult of the blood cockle and clam respectively.These concentrations were evaluated probably with the ammonia level in sediment environments in gulf waters for prawn culture (Rushan Eastbay), prawn culture ponds and shellfish culture ponds which make use of prawn culture pond water. |
