Hg. It has been also confirmed that carnivorous fish showed higher
MeHg concentrations than organisms with other feeding habits
and lower trophic levels, which implicates not only food chain
length but also feeding behavior can affect MeHg transfer and
accumulation to higher trophic levels. However, little is known
about the effect of feeding selectivity on the transfer of MeHg
through marine food chains. Because of the paucity of information
on this subject, the present study was undertaken on the microalgae
Chlorella sp., Nitzschia closterium and Isochrysis galbana, the
zooplankton Moina mongolica, Harpacticus uniremis and Artemia sp.
and the fish Paralichthys olivaceus, Scophthalmus maximus and Fugu
rubripes to establish an experimental marine food chain of three
levels in the laboratory. The main aim of this study is to clarify the
potential role of feeding selectivity playing in the transfer of MeHg
along marine food chains.
