Carbohydrates make up a significant portion of dissolved organic carbon within waterways. Apart from studies demonstrating that chondroitin causes avoidance behaviours in some species of fish, no work has been done to determine how fish respond to carbohydrates commonly found in their environment. In our study fathead minnows (Pimephales promelas) were attracted to N-acetyl-D-glucosamine, avoided D-arabinose, and had no response to either D-xylose or D-glucose using a behavioural assay. This study provides further evidence that carbohydrates may be important chemonsensory cues for fish. This article is protected by copyright. All rights reserved.
