Traceability and discrimination among differently farmed fish : a case study on Australian murray cod
The development of traceability methods to distinguish between farmed and wild-caught fish and seafood is becoming increasingly important. However, very little is known about how to distinguish fish originating from different farms. The present study addresses this issue by attempting to discriminat...

The development of traceability methods to distinguish between farmed and wild-caught fish and seafood is becoming increasingly important.

Thus, the combination of these isotopes can distinguish among fish originating from different farms. On the contrary, fatty acid and tissue proximate compositions and morphological parameters, which are useful in distinguishing between farmed and wild fish, are less informative in discriminating among fish originating from different farms. |
