Determination of some heavy metals in Mastacembelus mastacembelus (Banks & Solander, 1794) in terms of public health

In this study, the accumulation of some heavy metals in spiny eel (Mastacembelus mastacembelus Banks and Solander, 1794) living in Karakaya Dam Lake was determined and human health risk of this fish when consumed as food was examined. For this purpose, the amounts of copper (Cu), chromium (Cr), cadmium(Cd), iron (Fe), zinc (Zn) in water samples and in the muscle tissues of the fishes were determined. The amounts of heavy metals showed differences in the muscle tissues of Mastacembelus mastacembelus according to weight, length, sex and age groups of fish. In conclusion the amounts of heavy metals in the flesh of spiny eels were found lower than that recommended by EPA, WHO, FAO and TFC.

Hatay Açıklarında (Kuzeydoğu Akdeniz) yakalanan yeşilgöz balığının (Chlorophthalmus agassizi)'nin boy-ağırlık ilişkisi

This study was carried out to determine the length-weight relationship of green eye fish (Chlorophthalmus agassizi) that have economic importance and obtained from Northeast Mediterranean. For this purpose, total 454 individuals (165 females and 289 males) of C. agassizi were captured with a commercial trawler form 150-200 m in depth. Minimum-maximum length and weight of captured fishes were determined as 7.8-18.6 cm and 2.3-51.6 g for males and 7.0-17.5 cm and 1.8-42.5 g for females respectively. Length-weight relationships were found as W=0.0038*L3.2432 (r2= 0.969, SEb =0.089) for all individuals, W=0.0035*L3.2825 (r2=0.982, SEb =0.071) for females and W=0.0049*L3.1299 (r2=0. 944, SEb =0.098) for males. Length-weight relationship of this species, all individuals, females and males of this fish species showed a positive allometric growth (b>3).
