Abstract
The ability of codfish to associate ingestion of a food with toxicosis was investigated. After preliminary training to feed consistently, cod ate food which was followed by a single injection of lithium chloride. Preferences for “safe” nonconditioned food and the conditioned food were tested. Results of the first of two studies showed a greater aversion to the conditioned food compared to nonconditioned food. Though consumption of nonconditioned food was depressed during initial testing, the consumption of conditioned food was significantly less for six of eight test sessions. The drop in consumption of nonconditioned food was attributed in the second study to incomplete recovery from the drug. An aversion to familiar food was initially weaker compared to novel food and extinguished more rapidly.
