It is important to identify toxic elements in fish feeds to ensure the feed fish would
pose no health hazards to the fish. The objectives for this study were to assess and
compare the toxic elements in fish feeds which were fish pellets and trash fish. Toxic
element contents in the fish feeds were determined using inductively coupled-plasma
mass spectrometry (ICP-MS) and direct mercury analyzer (DMA). Standard Reference
Material (SRM) 2976 was used in trace element recovery and method validations. Oneway
ANOVA indicated significant differences in Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Cd,
Pb, and Hg (P < 0.05). The range for the toxic elements in all the fish feeds were low,
hence it was safe to feed the fish with the fish feeds.
