pH值对大菱鲆生长及鱼体生化组成的影响
Effects of pH on Growth and Biochemical Indices of Juvenile Turbot (Scophthalmus maximus)
摘要
Abstract
The variation of growth and common biochemical indices of juvenile turbot (Scophthalmus maximus) under different water pH were studied. The results showed that, in different time periods, the feed consumption ratio (FCR) increased, while the specific growth ratio (SGR) and the weight gain ratio (WGR) decreased with increasing pH. Regarding FCR, the ratios of pH 8.3 and pH 8.8 groups were significantly higher than that of other pH groups (P<0.05), and the SGR and the WGR of pH 8.3 and pH 8.8 groups were significantly lower than those of other pH groups (P<0.05). The moisture did not differ significantly in the six pH group (P>0.05). The crude fat of the whole body had a decreased trend with pH increasing, and the highest level was found at pH 6.3, and had evident differences compared with other pH groups (P<0.05), and no significant differences were found from pH 6.8 to 7.3 (P>0.05), but the content decreased significantly from pH 7.8 to 8.8 (P<0.05). As to the crude protein, no significant differences were observed from pH 6.3 to 7.3 (P>0.05), but the value significantly decreased from pH 7.8 to 8.8 (P<0.05). The content of ash had no significant differences from pH 6.3 to 7.3 (P>0.05), but increased significantly from pH 7.8 to 8.8 (P<0.05). To sum up, the results showed that pH 6.3-7.3 were regarded as the optimum range for the growth of juvenile S. maximus.关键词
