不同氨基酸组合对真鲷(Chrysophrys major)诱食效果的研究

Study on attractive effects of different combinations of four kinds of amino acids on red sea bream(Chrysophrys major)

试验以真鲷为试验对象,采用迷宫法,以丙氨酸、甘氨酸、精氨酸和组氨酸作为诱食剂原料,经不同组合后测定其对真鲷的诱食效果。结果显示,甘氨酸+组氨酸的诱食效果最好,其各种组合的诱食效果依次为甘氨酸+组氨酸>甘氨酸+丙氨酸>甘氨酸>组氨酸>丙氨酸>丙氨酸+精氨酸>丙氨酸+甘氨酸+组氨酸>精氨酸+组氨酸>甘氨酸+精氨酸>甘氨酸+丙氨酸+精氨酸>丙氨酸+组氨酸>精氨酸>丙氨酸+精氨酸+组氨酸>甘氨酸+丙氨酸+精氨酸+组氨酸。

For assessing the attracting effects of amino acids on red sea bream（Chrysophrys major）,take four kinds of amino acids,alanine,glycine,arginine and histidine amino acids as the material of attractants.In the experiment,mixed in different combinations of those four aimo acids,which was conducted to the attractant effect on red sea bream.The results showed that His＋Gly has the best attractant effect.This indicated that the feeding attraction activities were as follows： Gly＋HisGly＋Ala GlyHisAlaAla＋ArgGly＋Ala＋HisArg＋HisGly＋ArgGly＋Ala＋ArgAla＋HisArgAla＋Arg＋HisGly＋Ala＋Arg＋His.
