Gut contents of sand goby Pomatoschistus minutus showed higher C and N isotope values than the food before consumption. This enrichment was more pronounced in the hindgut than in the foregut, probably because of preferential assimilation of 12 C and 14 N along the gastro‐intestinal tract. The results indicated that the shift towards higher values in the alimentary canal occurs in the first 2 h after feeding.
