The effects of mixtures of attractants (L-lysine and L-alanine) and repellents (L-glutamic acid, L-cysteic acid, n-butyric acid and DL-malic acid) were examined on the behavior of the oriental weatherfish Misgurnus anguillicaudatus
The chemotactic activity of either 100MM of L-lysine or L-alanine was significantly affected by the addition of more than 10mM of each repellent. There was no difference in the activity of re-pellents. Similarly, the activity of 10MM of L-glutamic acid was affected by the addition of 1, 10 and 100mm of either L-lysine or L-alanine similar to each other. The same was true for repellents such as L-glutamic acid and DL-malic acid. It seems that the effects of repellents wer
more significant than those of attractants in the same concentrations.
