Investigations of temperature and pH variations on metal trophic transfer in turbot (Scophthalmus maximus)
International audience Studying dietary metal transfer kinetics is essential to gain a better understanding in global metal accumulation rates and its impacts in marine fish. While there exists a solid understanding on the influence of various biotic factors on this transfer, metal assimilation in f...

International audience Studying dietary metal transfer kinetics is essential to gain a better understanding in global metal accumulation rates and its impacts in marine fish. While there exists a solid understanding on the influence of various biotic factors on this transfer, metal assimilation in fish might be also affected by abiotic factors, as has been observed in marine invertebrates. The present study therefore aim to understand the potential effects of two climate-related master variables, temperature and pH, on the assimilation efficiency (AE) of essential (Co and Zn) and non-essential (Ag) metals in the turbot Scophthalmus maximus using radiotracer tools. Juvenile turbots were acclimated for 8 weeks at two and two temperatures (17° C and 20° C) and pH (7.5 and 8.0) regimes, under controlled laboratory conditions and then fed with radio-labelled shrimp (57Co, 65Zn and 110mAg).
