Description
Threeaquaticproducts,tilapiafish,lobsterandcrab,werecollectedfromthelandingsiteoffishermeninMakoko,afishingsuburb inLagosState,Nigeria.Theywereanalyzedfortheirproximatecomposition,andconcentrationofheavymetals(Cr,Cd,andPb) was also measured in them. The nutrient values varied among the three organisms. The lobsters and crabs had higher protein values while tilapia was richer in lipid and moisture content. In most cases, these differences were not significant. The concentrationofheavymetalsalsodifferedinthethreeorganisms.All organismshadhighconcentrationsofthethreeheavymetals analyzed.Theheavymetalloadasobservedinthisstudyisconsistentwithsomepreviouslyreportedvaluesinliterature.Plausible reasons for these differences were discussed in light of size, trophic level, choice of food of the organisms, and anthropogenic activities. It may be advisable that heavy metal concentrations are regularly monitored in edible aquatic food products so that human health is not at risk.
