摘要/Abstract

摘要： 研究不同pH对大菱鲆(Scophthalmus maximus)幼鱼平均日增重及鳃显微结构的影响。结果显示：大菱鲆平均日增重随pH升高而降低,pH 8.3和8.8组平均日增重显著低于其他处理组(P<0.05)。pH 6.3时鳃小片上皮细胞角质化较为严重;pH 6.8和7.8时鳃上皮细胞未见明显变化;pH 8.3时上皮细胞出现脱离,部分出现角质化;pH 8.8时上皮细胞角质化较为严重。结果表明,水环境pH在6.8~7.8范围内比较适宜于大菱鲆幼鱼的健康生长。

关键词: pH, 大菱鲆, 平均日增重, 鳃, 显微结构

Abstract: The average daily growth rate (AGR) and the microstructure of the gill of juvenile turbot (Scophthalmus maximus) were examined under different pH levels. The results show that the AGR decreased with increasing pH levels, and the AGR of pH 8.3 and 8.8 groups were significantly lower than that of other treatment groups (P<0.05). When the fish was exposed to pH 6.3, the lamellar epithelia were keratinized severely, no significant changes in lamellar epithelia were observed from pH 6.8 to 7.8, keratinization and lifting were found in the lamellar epithelia at pH 8.3, and the keratinization was more severe at pH 8.8. The results suggest that pH 6.8~7.8 is considered as the optimum ranges for juvenile turbot.

Key words: pH, Scophthalmus maximus, average daily growth rate, gill, microstructure
