Analysis of conditioned learning in Carassius auratus

Abstract

This study investigated the impact of unconditioned stimulus frequency and delay on classical conditioning in Carassius auratus, with the influence of time interval signaling on learning and conditioned behavior. Therefore, we focused on evaluating how temporal signaling affects the effectiveness of conditioning in fish. Since control of the environment is essential to optimize learning in aquatic animals. An experiment was designed in which two groups of Carassius auratus fish were subjected to a classical conditioning process for a period of 22 days. Group A experienced time intervals cued by a light, while group B was exposed to uncued intervals. Response times to the unconditioned stimulus and conditioned behavior were evaluated using statistical techniques. The results indicated that group B, which did not receive interval signaling, showed significantly shorter response times and continued improvement in learning compared to group A. In contrast, group A showed longer response times and an association less effective between silence and food. The conclusions revealed that interval signaling negatively affects the effectiveness of classical conditioning in fish learning. Therefore, the implementation of projects and programs focused on environmental conditioning and enrichment is proposed to optimize the well-being and adaptation of fish in controlled environments.
