Weighty metal, microbial profile and proximate of some preferred commercial marine fish collected from two markets in south western Nigeria

Abstract

The study on the elemental, proximate and microbial composition of fresh samples of Scomber
scombrus, Gadus macrocephalus, Saclina pilchradus and Jack mackerel was determined to gain the
knowledge of the risk and benefits associated with indiscriminate consumption of marine fishes. Wet
digestion was done for the samples and was analyzed for minerals, heavy metals and microorganisms.
The species examined contained appreciable concentrations of moisture, protein, lipids and ash
content suggesting that the fish species could be used as a good source of minerals. Heavy metals
analyzed were above tolerable limits; therefore, it can be suggested that taste, size, freshness and other
related external appearances should not be the only factor to be considered in making choice for
marketing and consumption of marine and freshwater fishes in Nigeria.
