“…Copper (Cu) and iron (Fe) are oligoelements which play vital roles in the enzymatic and respiratory processes of crustaceans. Zinc (Zn) is one of the important essential metals, a constituent of more than 90 enzymes and proteins which regulates the activities of many other enzymes (Bruland and Franks, 1983). Manganese (Mn) is needed for growth and good health in humans; magnesium (Mg) is an essential mineral for cell function and it occupies a key role in all reactions with phosphorus (P).…”

Both fresh and marine edible crustaceans Procambarus clarkii and Erugosquilla massavensis, respectively, are now important components of our local aquatic fauna in Egypt that have a small yet growing economic importance in our markets. So, the purpose of the present work was, therefore, to assess the protein, amino acids, fatty acids, minerals, vitamins, protein electrophoresis and dendrogram analysis of their extracts for the first time in Egypt which may be in the future play an important role in some pharmaceutical industries and may be used as a specific health foods (functional supplement). In the present study, nutritional analysis of muscle and exoskeleton extracts of P. clarkii and E. massavensis indicated the presence of a high amount of protein, 9 essential amino acids and 9 non essential amino acids including taurine which has a very scientifical action and benefit for men. Also, the results showed the presence of 9 unsaturated fatty acids which included essential fatty acids linoleic acid (Omega 6) and alpha linolenic acid (Omega 3) which have many functions for man (food supplement) in addition to 4 saturated fatty acids. The minerals recorded were Cu, Zn, Mn, Fe, Mg, Ca, K and P and the vitamins were Vitamims A, D, E, B 1 , B 2 , Bp, B 6 and B 12 . From the electrophoretic analysis of protein, the dendrogram analysis showed the highest similarity between the muscle and exoskeleton extracts of P. clarkii.

“…The interest in Mn stems in part from its reactivity which results in its dissolved distribution strongly reflecting its sources. For the surface ocean these sources include aeolian input, continental runoff and reducing inputs from continental shelf sediments [Klinkhammer and Bender, 1980;Trefry and Presley, 1982;Bruland and Franks, 1983]. Studies of the surface ocean Mn distribution therefore have the potential to provide information on these inputs.…”

“…It is well known that upwelling phenomena contribute to metals bioavailability in environment. Bruland and Franks (1983) reported in the coastal waters of California, elevated levels of Cd, Cu and Zn, explaining that it could be a result from the upwelling of nutrient-rich waters. The same result was also reported by Roméo and Gnassia-Barelli (1988) for Cd, Fe and Zn on the Mauritanian coast.…”

Trace metal distribution in pelagic fish species from the north-west African coast (Morocco)

In the current study, ten elements contents (Fe, Zn, Mn, Cu, Cr, Co, Ni, Cd, Pb and Hg) have been measured in muscle and liver of four pelagic fish species (Engraulis encrasicolus, Sardina pilchardus, Scomber japonicus and Trachurus trachurus) from the north-west African coast (South Atlantic Moroccan coast), collected during summer and autumn seasons (July and December 2013, respectively). Significant differences in metal contents were found between the different species (p \ 0.05). Metals levels were also much higher in liver than those recorded in muscle tissues. The concentrations of Fe, Zn, Cd, Co, Cu and Pb were significantly higher in mackerel liver (p \ 0.05).While, in muscle, anchovy presents a higher content of Mn, Cu, Cr, Ni and Pb. A high level of cadmium was recorded in liver of the different species which can be attributed to an anthropogenic source (phosphate industry) and to natural sources (upwelling activities). The main concentration of toxic elements (Cd, Pb and Hg) recorded in the four edible muscles of pelagic fish species, under study, were below the established values by the European Commission Regulations and show that their effect on the consumers health can be considered as negligible.
