摘要

草蝦(Penaeus monodon)於鹽度30 ppt下，暴露於0.001（對照組）、0.079、0.151、0.368及0.751 mmol/l亞硝酸經24小時。發現除了對照組外均有亞硝酸進入。耗氧及排氨隨外界亞硝酸濃度增加而增加。草蝦暴露於亞硝酸卽使濃度低至0.151 mmol/l其呼吸功能及氮代謝均受到影響。

Oxygen consumption(O2 mg/g/h)and ammonia excretion(N mg/g/h)of juvenilePenaeus monodon were measured for individual shrimp exposed to 0.001(control),0.079,0.151,0.368 and 0.751 mmol/l nitrite for 24 h in a salinity of 30 ppt(part per thousand).Nitrite uptake occurred for all groups except the controls.Oxygen consumption and ammoniaexcretion increased directly with ambient nitrite.It is suggested that the respiratoryfunction and nitrogen metabolism are affected for the P.monodon following exposure tonitrite as low as 0.151 mmol/l.
