ABSTRACT

A series of vented chambers with various concentrations of agents in question was freely accessible for fish larvae. 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.
