Micro-pollutant content in Anguilla anguilla glass eels and relationship with migratory behaviour

cited By 2International audienceThe concentrations of ten trace elements (barium, cadmium, cobalt, copper, lead, manganese, nickel, strontium, vanadium and zinc) were determined in the whole-body of glass eels caught in the Adour estuary, and exhibiting different levels of activity in laboratory. Glass eels that become "active" in response to a decrease in light intensity in flume present significantly lower values than those remaining buried in the substratum for Ph (p = 0.010) and Zn (p = 0.049). Results are discussed in relation to migratory behaviour
