不同盐度条件下亚硝酸态氮与非离子氨对花鲈幼鱼的毒性实验
Toxicity of unionized ammonia and nitrite on juvenileLateolabrax maculatus according to salinity
摘要
Abstract
The toxicity of unionized ammonia and nitrite on juvenileLateolabrax maculatus (weighing 50.33 ± 4.35 g) was studied at different salinity levels of 0, 10, and 20. The effects of salinity (0, 10 and 20) and ammonia exposure (0, 5, 10, 15 and 20 mg/L) on oxygen consumption and ammonia excretion of juvenileL. maculatus were also evaluated.The results showed that the safe concentration values of nitrite for L. maculatus at salinity levels of 0, 10 and 20 were 16.357, 52.540 and 58.622 mg/L, respectively. The safe concentration values of ammonia–N (union-ized plus ionized ammonia as nitrogen) forL. maculatus at salinity levels of 0, 10 and 20 were 0.794, 4.625 and 5.163 mg/L, respectively. The safe concentration values of ammonia–N (unionized plus ionized ammonia as nitro-gen) forL. maculatus at salinity levels of 0, 10 and 20 were 0.584, 2.313 and 1.951 mg/L, respectively. The oxygen consumption and ammonia excretion of juvenile L. maculatus were significantly affected by salinity and ammonia exposure. Oxygen consumption and ammonia excretion reached the minimum values at salinity level of 10.关键词
