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。
研究不同pH對大蔆鲆(Scophthalmus maximus)幼魚平均日增重及鰓顯微結構的影響。結果顯示:大蔆鲆平均日增重隨pH升高而降低,pH 8.3和8.8組平均日增重顯著低于其他處理組(P<0.05)。pH 6.3時鰓小片上皮細胞角質化較為嚴重;pH 6.8和7.8時鰓上皮細胞未見明顯變化;pH 8.3時上皮細胞齣現脫離,部分齣現角質化;pH 8.8時上皮細胞角質化較為嚴重。結果錶明,水環境pH在6.8~7.8範圍內比較適宜于大蔆鲆幼魚的健康生長。

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.
