In this study accumulation of some heavy metals Cadmium (Cd), Chromium (Cr), Cobalt (Co), Nickel (Ni) and Lead (Pb) in the operculum, gills, heart, kidney, muscle and vertebrae were determined in some fishes (Hydrocynus forskahlii, Hyperopisus bebe occidentalis and Clarias gariepinus) collected from fishermen around Ogun estuary. The accumulation of the metals in different organs showed significant differences (P<0.05) except lead accumulation. However, the bioaccumulation of the heavy metals was species-related as the accumulations of the heavy metals analysed in the sampled fishes were of the following trend: H. forskahlii > H. bebe occidentalis > C. gariepinus and the pattern of distribution was Ni > Cr > Co > Cd > Pb for all the fish species. The levels of Ni and Cr in this study were higher than the maximum permissible limits (FAO, UNEP, FEPA and WHO) for human consumption and that of Cd, Pb and Co were still lower. Safe disposals of domestic sewage and industrial effluents as well as enforcement of laws enacted to protect our environment are therefore advocated.

“…It has been found that the liver attained the highest accumulation values of heavy metals followed by the gills. These findings agree with the results of [32,33] and [34] who found that the distribution of the heavy metals in the investigated organs was shown to follow the order: liver > gills > muscles.…”

“…The use of different kinds of livestock manure in fish production may increase the level of pathogenic bacteria causing a public health risk to the rural community [11]. It has been highlighted that fish consumption can be an important avenue for human pathogenic bacteria and other food borne diseases exposure to man [12]. Pathogens from fish can be transmitted to humans through both active and passive contact and may cause food borne diseases such as dysentery, typhoid fever, salmonellosis and cholera.…”

The occurrence of bacterial isolates in fin-fishes (Clarias gariepinus and Coptodon guineensis) from the humic ecosystem of Eniong River, Akwa Ibom State was investigated. The results obtained from pour plate analysis showed that the fin-fishes contained bacterial contaminants. The bacterial loads varied with the type of fin-fish and were much higher in fish intestines, when compared with the skin and gills. The heterotrophic bacterial loads obtained exceeded the 1.2 x 10 5 cfu/g limit recommended for fresh fishes. High and unsafe fecal coliform (1.1 ± 0.57 x 10 3 cfu/g -2. ± 0.26 x 10 3 cfu/g) loads were also obtained. The culture-able bacteria species associated with the fin-fish samples include Staphylococcus sp, Klebsiella sp, Bacillus sp, Enterobacter, Streptococcus sp, Micrococcus sp, Lactobacillus, Serratia sp, Proteus sp, Salmonella sp, Shigella sp, and Escherichia coli. The percentage of occurrence of the isolates in the various fish samples was also found to vary with the fish species. Staphylococcus sp had the highest rate of occurrence of 63% and 44.4% in C. gariepinus and C. guineensis respectively while the least prevalent organism was Micrococcus sp Umana et al.; JAMB, 6(1): 1-12, 2017; Article no.JAMB.36529 2 with 7.41%, and Serratia and Shigella sp with 11.1% for C. gariepinus and C. guineensis respectively. Twelve bacterial species with variable virulent potentials were isolated. The analysis revealed that each of the isolates exhibited varying degree of virulence. Of the 12 bacterial isolates obtained from the various fish samples, ten (Bacillus cereus, Micrococcus sp, Streptococcus sp., Proteus sp, Serratia sp, Salmonella sp., Shigella sp., E. coli, Enterobacter sp and Lactobacillus sp had the potentials to produce lipases enzyme. This enzyme is responsible for breaking down lipids. Among the isolates Stahylococcus aureus was the most virulent. The results indicate poor microbiological quality. These call for proper processing of aquatic foods as well as routine monitoring. Original Research Article
