几种氨基酸和植物提取物对鲤、鲫鱼诱食活性的初步研究

A PRELIMINARY STUDY ON FEEDING ATTRACTION ACTIVITIES OF SEVERAL KINDS OF AMINO ACIDS AND THE EXTRACTS FROM PLANTS FOR COMMON CARP (Cyprinus carpio)AND CRUCIAN CARP (Carassius auratus)

本试检采取迷宫法，做了氨基酸单体、氨基酸不同组合，以及一种复合氨基酸与几种植物提取物的混合物对鲤、脚鱼的诱食活性试验。结果表明：1．低浓度的DL一甲硫氨酸对鲤鱼有显著的引诱作用（P＜0．05），而高浓度的甘氨酸对鲫鱼则有显著的抑制作用（P＜0．05）。2．L一缅氨酸＋L－组氨酸＋L－精氨酸（组合1）对鲤鱼的引诱作用极为显著（P＜0．01）。L－本丙氨酸＋L－组氨酸＋L－精氨酸（组合2）对卿鱼有极强的引诱作用（P＜0．01）在组合2中加入10ml丁香油对哪色仍然有极强的引诱作用（p＜0．01）；当加入10ml15％的香果提取液对鲫鱼引诱效果不显著，但对鲤鱼却有极强的引诱作用（p＜0．05）；当加入大蒜、香精、丁香等植物提取物则对鲤鲫鱼都有显著的抑制作用（P＜0．05）。

This experiment was conducted to find the feeding attraction activties for common carpand crucian carp by means of amino acids monomer, different combinations of amino acids, themixture of a compound amino acids and the extracts from several kinds of plants. The resultsshowed that (1) lower concentration bf DL-Met had extinguish attraction, effect on common carp(p< 0. 05). Higher concentration of 1, - Gly had notably inhibition effect on crucian carp(p<0.05). (2) The combinations of I, - Val + L - His + L, - Arg (group 1 ) had notable attraction ef-fect on common carp (p< 0. 01).The comhinations of L - His + L - Phe + L - Arg(group 2 ) had a strong attraction effect oncrucian carp (p< 0. 01), even when 10ml of clove oil added to gronp 2 p< 0. 01); 10 ml of thecrude extract of pimenta officinalis had no strong attraction effecton while an addition of cruciancarp, but it had a notable attraction effect on common carp (p< 0. 05 ).When added the compound extracts of plants such as gralic, essence, clove oil etc., lt hadsignificant inhibition effect on both common carp and crucian carp (p< 0. 05).
