dc.description.abstractEndogenous opioid peptides have been implicated as stimulators of the central feeding system, and the opioid antagonist naloxone (NAL) suppresses feeding behavior in a variety of vertebrate and invertebrate species. In 24 h food deprived goldfish, NAL (10.0 µg/g BW) increased the latency to first feeding and reduced the number of pellets ingested. NAL treatment was more effective in morning than afternoon trials. The effectiveness of NAL was dependent on the duration of food deprivation NAL treatment was most effective after a 24 h period of food deprivation, with less effect following 12 or 48 h of food deprivation. NAL treatment did not suppress feeding behavior in fish tested 6 h after their last meal. NAL treatment did not decrease general locomotor behavior, indicating a specific effect on the feeding system. These results implicate endogenous opioid peptides in the regulation of feeding behavior in goldfish.
