This study analyzed three popular species of fish in raw and cooked (curriedand fried) form, commonly consumed in Karachi coast and overall inPakistan for their essential and heavy metal composition. The outcomesrevealed that the content of toxic heavy metal (Hg) was observed in all rawsamples particularly in raw Mulla fish (Lethrinus nebulosus) but heattreatment by frying and curry preparation of fish led to a decrease of Hgcontent in the muscles of all selected species especially in L. nebulosus afterfrying. While in Acanthopagarus arabicus Hg content was below detectablelevel. In this study the levels of Cd and Cr were observed at below detectablelevels in all selected species except in A. arabicus where Cd tend to decreaseafter frying while the content of Cr slightly increase after both types ofcooking. In the present study the essential metals namely Fe, Zn, Cu and Mntend to increase in all fin fishes after cooking, especially in curried form.The above-mentioned result determined that these customary culinarypractices of fish have an influence on their essential and heavy metalconstituents. Furthermore, eating variety of fin fish species by applyingdifferent procedures of cooking is the finest attempt to attain better-qualityof dietetic ways, minimizing mercury revelation and increasing chance toobtain vital elements.
