利用自制触球及迷宫法评估了百里香酚、香芹酚、丁香酚和肉桂醛4种香精对(4.45± 0.58) g黄颡鱼(Pelteobargrus fulridraco)幼鱼的诱食剂量效应反应,试验结果表明:百里香酚、香芹酚和肉桂醛都对黄颡鱼有明显的诱食作用,其最适诱食浓度分别为(0.025~ 0.05)、0.025、0.007 g/mL;百里香酚诱食效果最佳(P < 0.05),但浓度过高,也会出现诱食抑制;而丁香酚对黄颡鱼幼鱼均无明显的诱食作用(P >0.05)。随后在基础饲料中分别添加75、150、250、500和1000 mg/kg的百里香酚饲喂黄颡鱼幼鱼,8周的养殖结果表明黄颡鱼增重率(Y)与饲料中百里香酚添加量(X)之间可用二次方程式表示Y=-0.000 7 X~2+ 0.796 3 X+ 107....

The experiment was conducted to evaluate dose - resjDonse of attractant effects of fbai maze and /rowtli performance of tliymol on Pelteobargrus fiilridraco la rv a e, the results showed that eu /enol was non -significant attractant effect （P 〉0. 05）,thus thyme,parsley and cinnamaldehyde were obvious, which optimal concentra-tions by ball maze were 0. 025 ？0. 0 5,0. 0 2 5,0. 007 %/mLrespectively. Thymol was the best attractant effect （ P 〈0. 05）. However, the concentration was too h igh, its attraction would be inhibition. The feeding tr...
