Effects of Exposure to Sublethal DDT on the Locomotor Behavior of the Goldfish (Carassius auratus)

Abstract

A highly significant time-dependent correlation between consecutive turns in the locomotor pattern of normal goldfish (Carassius auratus), attributed to a "memory" process in the pertaining locomotor control mechanism in the central nervous system, is significantly reduced within 4 days by chronic exposure of the fish to 10 μg/liter p.p′. DDT. Keeping the fish in clean water during 130–139 days did not result in the restoration of the above correlation.
