In this study, the effects of nitrogen fertilizer (NH4NO3
+ CaMg (CO3)2) on Capoeta capoeta (Guldensteadt, 1773) were studied
with electrophoretic and histopathological methods. The fish caught from Kars
Creek (TURKEY) were put into 300 liters tanks and they were enabled to adapt to
the medium for 10 days. Then they were divided into 3 groups. The fish in the 1st
group were held in normal water, 2nd and 3rd groups were
held in the water containing 15 mg/L and 30 mg/L nitrogen fertilizer
respectively for 15 days. At the end of this period, blood and tissue samples
were taken from the fish for electrophoresis and histopathological examination.
Serum samples obtained were carried out in Sodium Dodecyl Sulphate
Polyacrylamide Gel Electrophoresis (SDS-PAGE). Tissue samples were fixed in %10
formaldehyde solution, and paraffin blocks were prepared by routine
histological methods and section 3-5 µ thickness were performed and all of the sections were stained with
hematoxylin and eosin method and investigated under light microscope. In
SDS-PAGE of serum proteins, new protein expression as well as thinning and
thickness in various protein bands of fish applied nitrogen fertilizer were
observed.
In histopathological examination, increasing levels of
degeneration, necrosis and mononuclear cell infiltration were observed in the
tissues of the liver, intestine, gill and kidney tissues of experimental fish
groups in proportion with the increasing of dose.
It is concluded that contamination of nitrogen fertilizer
in aquatic environments can have harmful effects on fish.
