Abstract

The concentration of 14 major and trace elements in catfish (Ictalurus punctatus) frames was determined and analyzed for differences. Three frames were obtained each week for five consecutive weeks in the spring and the fall of 2000. The frames were freed of remaining flesh, dried, treated by microwave dissolution technique and the minerals determined by inductively coupled plasma optical emission spectrometry (ICP-OES). The mean calcium concentration (mg/kg, dry basis) in the spring (140 400) was not significantly (P > 0.05) different from that in fall (167 000). Among the heavy metals (Cd, Pb, and Al) the concentration of Cd varied significantly (P < 0.05) from week to week but not from season to season. The concentration of all the above-mentioned heavy metals did not exceed the critical level for human consumption.
