The effect of the addition of marine algae in fish feed on the levels of bromophenols in fish flesh was studied. These bromophenols include 2-bromophenol, 4-bromophenol, 2,4-dibromophenol, 2,6-dibromophenol, and 2,4,6-tribromophenol. Two types of algae-containing fish feeds with 30% Padina arborescens and 30% Sargassum siliquastrum were developed. The total bromophenol contents of these feeds were 132 and 340 ng/g respectively, which were significantly higher than that of the control feed (8.9 ng/g) (ANOVA, p < 0.05). Silver seabream was used as the model fish for the feeding experiment. Bromophenol contents of both fish gut and flesh were monitored at 2-week intervals throughout the 8-week period. Two-way ANOVA showed that only the 30% S. siliquastrum-containing feed significantly (p < 0.05) increased the total bromophenol content in the fish flesh with time. This also produced sensorial differences in the fish flesh.
研究了在鱼饲料中添加海藻对鱼肉中溴酚含量的影响。这些溴酚包括2-溴酚、4-溴酚、2,4-二溴酚、2,6-二溴酚和2,4,6-三溴酚。开发了两种分别含有30% 树状鹧鸪菜和30% 长囊马尾藻的含藻鱼饲料。这些饲料中总溴酚含量分别为132和340 ng/g，显著高于对照饲料（8.9 ng/g）（方差分析，p < 0.05）。黑鲷被用作投喂实验的模式鱼。在整个8周期间，每隔2周监测鱼肠道和鱼肉中的溴酚含量。双向方差分析表明，只有含30% 长囊马尾藻的饲料随着时间的推移显著（p < 0.05）增加了鱼肉中的总溴酚含量。这也在鱼肉中产生了感官差异。
