“…The values of Fe were in the order: T. zilli > S. galilaeus > C. nigrodigitatus. High concentration of Fe was reported in fish organs (El-Naggar et al, 2009) and was reported as the most abundant in C. nigrodigitatus compared to other fishes evaluated (Asuquo et al, 2004). However, the values obtained for Fe in this study were lower compared to freshwater fishes in China (Du et al, 2012).…”

“…The values of Fe in the fish organs were in the order: Gill > Liver > Kidney > Muscle. High concentration of Fe had been reported in fish organs (El-Naggar et al, 2009) and was reported as the most abundant in C. nigrodigitatus compared to other fishes evaluated (Asuquo et al, 2004). However, the concentrations obtained for Fe in this study were higher compared to values reported for this fish in Ibeshe, Lagos lagoon (Ladigbolu et al, 2011).…”

“…The fish investigated for heavy metals in the present study Cat Fish (Chrysichthys nigrodigitatus) is a commercially exploited species and occur frequently in Nigeria coastal waters. Accordingly, a couple of studies about heavy metal levels in different tissues of this fish species were published (Oyewo, 1998;Asuquo et al, 2004;Ladigbolu et al, 2011 andOpaluwa et al, 2012).…”

The occurrence of metals viz., lead (Pb), zinc (Zn), copper (Cu), iron (Fe), cadmium (Cd) and chromium (Cr) in water and fish ( Chrysichthys nigrodigitatus) samples collected bi-monthly from nine stations (water) and 3 designated landing sites (fish) of Badagry creek were investigated using atomic absorption spectrophotometer (AAS) method. With an exception of cadmium, metals concentration was lower in the water samples and higher in the fish tissues, indicating a bioaccumulation tendency of fish. Concentration levels in water were found in decreasing order of magnitude Cr > Pb > Fe > Zn > Cu > Cd. However, metals investigated except Cu (highest concentration in the liver) had highest concentrations in the fish gills, which could be related to the uptake pathway. The relatively lower wet season Cu, Pb, Cr and Cd in water could be attributed to a dilution effect of rainfall. Although, presently the mean concentrations of all the heavy metals except Pb in this study were moderate and within the Federal Environmental Protection Agency (FEPA) permissible standard limit for aquatic life , the elevation of metal concentrations in this creek is inevitable under the prevailing conditions of increasing urbanization, industrialization and other forms of modernization in Badagry and environs. Nevertheless, it is imperative to ensure regular monitoring of heavy metal loading in this creek and other water bodies with a view to safeguard public health.

“…In the present study we found that the ash content varies from (1.48± 0.18 to 2.59±0.09%), this results gave an indication, that the fish samples are the good sources of minerals. Asuquo et al 28 stated that fresh water species contains low ash content compare to marine aquatic species, because they live in high salinity environment. The ash content for all the three fish samples observed were not exceeding the world health standard above 5%.…”

Now days the potential toxic effect of heavy metals in the aquatic organisms has been intensively studied. The present study was aimed to determine the proximate composition and the heavy metal concentrations (Cd, Pb & Cr) of three different marine fish species Grey mullet (Mugil cephalus), Red snapper (Lutjanus sanguineus), and Indian sardine (Sardinella longiceps) along with the water sample collected from the southeast coast region located in Pondicherry state. These results revealed that the proximate composition of L. sanguineus had higher protein content (19.98%) and S. longiceps had higher fat content (10.03%), Fresh M. cephalus had higher moisture content (84.04%) whereas L. sanguineus had the highest ash content (2.59%) respectively. The metal concentration in seawater was found in the following order: Cr 0.
