Effects of zinc sulphate on transcaucasian barb,(Capoeta capoeta [Guldenstaedt,1773]) plasma nitric oxide,malondialdehyde and total sialic acid levels [Siraz bali{dotless}ǧi{dotless} (capoeta capoeta [guldenstaedt,1773]) plazma nitrik oksit,malondialdehit ve total sialik asit düzeyleri üzerinde çinko sülfati{dotless}n etkileri]

The aim of this study was to investigate plasma total sialic acid (tsa),nitric oxide (no) and malondialdehyde (mda) levels in response to different doses of zinc sulphate (znso4) in capoeta capoeta. the fishes were kept in tanks for 15 days for adaptation. three groups of fish (control,1st,and 2nd),each containing 9 fishes,were placed in separate tanks containing no,5 and 10 mg/l znso4,respectively for 10 days. at the end of the study,blood samples were taken,and plasma tsa,no and mda levels were analyzed. an increase in plasma tsa and mda levels were found along with increasing znso4 amounts,and a decrease in no levels was observed. in conclusion,it was determined that levels of tsa,mda and no were altered depending on znso4 doses applied in c. capoeta.
