Experiments were conducted on the ability of TaqMan molecular probes to detect plaice Pleuronectes platessa DNA from eggs, and cod Gadus morhua DNA from eggs and larvae following ingestion by a teleost predator, whiting Merlangius merlangus. Estimated half‐life
detection rate (T50) for eggs was 31 h, and 26 h for larvae, with some positive detections occurring even after visual inspection indicated complete gut clearance. Because TaqMan probes are taxon specific, the results presented demonstrate that this technique can provide a means of rapid and
unambiguous detection of predation by teleosts on fish eggs and larvae.
