Abstract: MF (Granite), MF (Granite) rare earth, chelates or inorganic salt were added to carp (\%Cyprinus carpio\%) feed, respectively, and growth performance was examined. The results illustrated that the carp fed MF(Granite) rare earth group (Ⅰ) had the best growth followed by the fish fed chelates group and MF (Granite) rare earth group (Ⅱ), MF (Granite) group and inorganic salt. There was the poorest growth in control without trace element addition. The variance analysis demonstrates that there was significant difference (\%P<0 01\%) in average weight gain rate between the three treatments and the chelates group in which MF (Granite) was blended and inorganic salt group (\%P<0 05\%) There was no significant difference between the MF (Granite) rare earth group (Ⅱ) and the MF (Granite) rare earth group (Ⅱ) and the chelates group (\%P>0 05\%). The analysis of nutrition composition of the fish mussles indicates that the contents of crude protein and fat in the three experiment groups within chelate addition MF (Granite) were slightly more than those in control and inorganic salt group, but there was no significant difference (\%P>0 05\%)
