The trophic transfer and nutritional toxicity of mercury (Hg) in aquatic food chains is well known, but there is limited information on the mechanism of mercury uptake across the gut. In this study, isolated whole gut sacs from rainbow trout were used to identify the regions of the gut involved in Hg absorption, and then perfused intestines were used to(More)
There are few dietary Copper (Cu) toxicity studies on warm water fish. We used the African walking catfish (Clarias gariepinus) to perform the first in vivo dietary Cu toxicity study on this species. We measured end points normally associated with metal toxicity (nutritional performance, haematology, histology, tissue Cu, Na(+), and K(+), Na(+)K(+)-ATPase(More)
