Accumulation of some heavy metals in Raphidascaris acus (Bloch, 1779) and its host (Esox lucius L., 1758).

Concentrations of some heavy metals (Fe, Zn, Cu, Mn and Cr) in liver of pike (Esox lucius L., 1758) and its endoparasite [Raphidascaris acus (Bloch, 1779)] inhabiting Işikli Lake (Turkey) were analyzed using atomic absorption spectrophotometry. Only Fe and Zn were detected in R.

Helminth infections in common carp, Cyprinus carpio L., 1758 (Cyprinidae) from Kovada Lake (Turkey).

The aim of this study which was carried out from March 2003-February 2004 was to determine the parasites of carp (Cyprinus carpio L., 1758) inhabiting the Kovada Lake. During the study, a total of 63 common carps were caught in different regions of Kovada Lake each month and investigated parasitologically.

[The effects of parasites on the growth of the crucian carp (Carassius carassius L., 1758) inhabiting the Kovada Lake].

The aim of this study carried out between March 2003-February 2004 was to determine the effects of parasites on the growth of the crucian carp (Carassius carassius L., 1758) inhabiting the Kovada Lake. A total of 102 specimens were caught monthly and investigated parasitologically.

Seasonal variations of heavy metals in some organs of carp (Cyprinus carpio L., 1758) from Beyşehir Lake (Turkey).

In this study which was carried out between March 2003 and February 2005 Fe, Cu, Zn, Mn, Cr, Pb and Cd contents were determined in muscle, liver and gill of carp (Cyprinus carpio L., 1758) caught from Beyşehir Lake. Among the heavy metals analyzed Cr, Pb and Cd were below the detection limit (<0.

[An investigation of parasites of goldfish (Carassius carassius L., 1758) in Kovada Lake.].

The aim of this study, carried out from 25.03.2003-17.

[Seasonal distributions and effects of parasites in pike (esox lucius l., 1758) inhabiting the işikli dam lake (Denizli).].

The aim of this study carried out from December 2000-November 2001 was to determine the endoparasites of pike (Esox lucius L., 1758) inhabiting the Işikli Dam Lake. A total of 160 samples were caught and investigated parasitologically.

Comparative study on the accumulation of heavy metals in different organs of tench (Tinca tinca L. 1758) and plerocercoids of its endoparasite Ligula intestinalis.

Concentrations of heavy metals (Cu, Fe, Zn, Mn, Cr, Pb and Cd) in some organs of tench and tissues of its parasite found in Kovada Lake (Turkey) were analyzed using atomic absorption spectrophotometry and subsequently compared with the data from sediments and water. Only Cu, Fe, Zn and Mn were detected in water, sediment, plerocercoids of Ligula intestinalis and fish samples, while levels of Cr, Pb and Cd were below the detection limits. Four elements were found at higher concentrations in the plerocercoid than in different fish tissues (muscle, liver and gill), being 1.
