In this paper; the concentrations of Pb, Cd, Cr, Zn, Cu, Mn and Fe were determined in the muscle tissues of seven marine and one fresh water fish species. Marine fishes were collected from the Mediterranean sea of the shore of Misurata; while fresh water fishes were collected from Tawarga stream located at about 65 Km west of Misurata according to fish habitat and type of heavy metal itself. Different fish species were collected from different Libyan localities. The results showed that the highest levels of lead, cadmium, chromium, zinc, copper, manganese and iron were found in Bolty (1.64 mg / kg ), Bouri (0.07 mg / kg ), Sardine (0.93 mg / kg), Denis (5.84 mg / kg), Balameat (0.97 mg/kg), Sardine (0.57 mg / kg), and Maghazel (8.61 mg / kg ) fish, respectively. The lowest levels of lead, cadmium , chromium , zinc and copper, were found in Balameat, (0.71 mg / kg ), Sardine (0.03 mg / kg ), Maghazel (0.06 mg / kg ), Bolty (2.1 mg / kg ) and Bolty (0.46 mg / kg ) fish , respectively. With regard to manganese, the lowest levels were observed in Kawally (0.25 mg / kg ), and Maghazel (0.24 mg / kg ), whereas Denis and Tuna fish showed lowest levels of iron (1.17 mg / kg ).

“…Additionally, temperature and salinity may have positive relationships with skeletal Sr (Balter and L ecuyer 2010;Torz and Nedzarek 2013). Emara et al (1993) observed a positive relationship between Mn, Fe, and Cu concentrations and trophic level, suggesting that these metals may be actively regulated. Although Mn in bony tissue can increase in fishes exposed to high concentrations of this element (Lockhart and Lutz 1977;Fraser and Harvey 1982;Moreau et al 1983), Bendell-Young and Harvey (1986) found that this relationship was not clearly defined because Mn is also homeostatically regulated.…”

“…In fish bodies, skeletal tissue generally has the highest mineral content among tissues (Rosenthal 1963;Emara et al 1993;Lall 2002;Roy and Lall 2006). Additionally, acellular bone may have a higher mineral content than cellular bone (Roy and Lall 2006); in this regard, fish endoskeleton may be well-suited for microchemistry analysis.…”

Microchemical analyses of fish otoliths have revolutionized fisheries science. Molecules deposited within otoliths may originate from ambient water and diet, with molecular concentrations being subject to subsequent physiological alteration after exposure. Analyses of otolith microstructure and incorporation of inorganic elements have led to major advances in stock assessment and fisheries ecology. However, the use of otoliths for microchemical analyses has drawbacks. Specifically, otolith removal from live specimens requires specimen sacrifice, which may be forbidden in the case of protected species. In addition, otoliths rarely contain sufficient concentrations of organic matter to allow reconstruction of food-web relationships via multiple stable isotopes, and otolith microstructure can be difficult to interpret in some species. Here, we review alternatives to otoliths that can provide microchemical analytes for life-history studies in fishes. Our focus is to describe advantages and disadvantages to the use of each alternative structure, with particular attention paid to trace-element analysis for inorganic matrices and stable-isotope analysis for organic ones. In general, the chronological analysis of elemental and isotopic values within each structure depends on the inert nature (or lack of molecular turnover) of the tissue. Structures with high turnover rates or those that are metabolically active will not effectively record elemental or isotopic compositions over time. Here, we provide an assessment of the use of bony endoskeleton, fin spines, fin rays, scales, and eye lenses as alternatives or complements to fish otolith analysis.

The concentrations of Na, K, Ca, Mg, Ba, Sr, Fe, Al, Mn, Zn, Pb, Cu, Ni, Cr, Co, Se, U, and Ti were determined in the flesh and osteoderms of estuarine crocodiles (Crocodylus porosus) captured in three adjacent catchments of Kakadu National Park, within the Alligator Rivers Region of northern Australia. This study provides, for the first-time, baseline concentrations of elements in both flesh and osteoderms of wild crocodiles. Multiple linear regression analyses were used to determine the effects of total crocodile length, estimated age, gender, inferred reproductive status, physical condition, and catchment of capture on element concentrations in both tissues. The Mg concentration (log10) in the flesh and osteoderms of C. porosus significantly (p < or = 0.001) decreased with increasing length (1.7-5.0 m) and estimated age (5-40 years). Similarly, the Ti concentration (log10) in flesh significantly (p < or = 0.01) decreased with increasing length. In contrast, Zn and Se concentration (log10) in flesh significantly (p < or = 0.001) increased with increasing length and/or age, suggesting that these relationships are mediated by biological rather than environmental chemical factors. In flesh, Fe and Na concentrations (log10) significantly (p < or = 0.05) increased as the physical condition of C. porosus deteriorated. No significant (p > 0.05) effects of gender or inferred reproductive status on element concentrations in the flesh and osteoderms were found. The mean concentrations (log10) of Al, Ba, Cr, Ni, and Pb in flesh and Co, Fe, Mg, Mn, and U in the osteoderms were significantly (p < or = 0.01) different between catchments. The significant (p < or = 0.05) effects of catchment on the concentrations of various elements indicate that C. porosus reflects the chemistry of its environmental milieu and therefore has a certain degree of catchment fidelity, even though the catchments are adjacent to one another. Such catchment-specific signals may be useful in the determination of the provenance of itinerant crocodiles. They also point to the utility of crocodiles as long-term biomonitors of their environment.
