Experimentele bepaling van de weefselspecifieke turnoversnelheid van stabiele C en N isotopen bij de mariene grondel ( Pomatoschistus minutus )

In order to study the migration patterns of the marine sand goby Pomatoschistus minutus between the North Sea and the Schelde estuary using stable C and N isotopes, it is essential that the tissue specific turn over rates are known. Also, it is a prerequisite for this technique that an isotopic gradient between the two migration endpoints is present. The two main aims of this thesis were to assess the turn over rates for muscle, liver and heart tissue of P. minutus and to verify the C and N isotopic gradients in the Schelde estuary.To characterize the tissue specific turnover rates of the juve...
