Effects of waterborne Fe(Ⅱ) on juvenile turbot Scophthalmus maximus: analysis of respiratory rate, hematology and gillhistology
摘要
Abstract
The concentration of Fe(Ⅱ) is high in some groundwater supplies used in turbot culture,and the toxicity of waterborne Fe(Ⅱ) is unknown.We investigated the stress responses of juvenile turbot,Scophthalmus maximus,exposed to Fe(Ⅱ) of different concentrations (0.01,0.05,0.1,0.5,1,and 2 mg/L)for 1,7,14,and 28 d,under the same ambient conditions of other parameters.Changes in respiratory rate,hematological parameters,and gill structure were determined.The results show that waterborne Fe(Ⅱ)did not cause severe hematological perturbation to turbot.A low-medium Fe(Ⅱ) concentration (lower than 0.1 mg/L) could boost the respiratory rate,and caused no or very limited damage to fish.A high Fe(Ⅱ) concentration (0.1 mg/L or higher),however,caused gill damage,such as vacuoles in branchial lamellae,epithelial necrosis,and hypertrophy of epithelial cells,and even death after extended exposure time.Therefore,excess waterborne Fe(Ⅱ) and long-term exposure to Fe(Ⅱ) could be responsible for poor growth and high mortality of turbot in culture.The concentration of waterborne Fe(Ⅱ) in turbot culture should be kept below 0.1 mg/L.关键词
