Numbers of larvae found in one or another chamber at certain time intervals served as a measure of medium preference or avoidance. Larvae of grass carp, silver carp, and bighead carp preferred concentrations of CO2 of 1−13 mg/L. Larvae of grass carp did not clearly react to Zn concentrations from 0.01 to 5 mg/L. Four-day larvae of this species are incapable of distinguishing Zn concentrations which are lethal for them. Five-day larvae of common carp do not perceive differences in content of amino acids dissolved in water. %8 2000-02-01
