Changes in hematological and biochemical parameters of European chub (Squalius cephalus L.) in unpolluted reservoir and polluted creek [Avrupa tatli{dotless}su kefali (Squalius cephalus L.)'nin temiz baraj ve kirli çay'daki hematolojik ve biyokimyasal parametrelerindeki deǧişimler]

This study investigates the surface water quality parameters of the atikhisar reservoir and sari{dotless}çay creek,both of which are located in çanakkale,the north-west part of turkey. the conductivity,cod,bod,tp,tn,and tss content of water in sari{dotless}çay creek were higher than in atikhisar reservoir (p<0.05),however; water do content in sari{dotless}çay creek was less than in atikhisar reservoir (p<0.05). chl-a concentration,temperature,salinity and ph of water were not statistically significant in both of the resources (p>0.05). the quality of surface water samples of atikhisar reservoir and sari{dotless}çay creek were accepted first quality and third quality,respectively. the blood samples of european chub (squalius cephalus l.) caught in the atikhisar reservoir (unpolluted) and sari{dotless}çay creek (polluted) provided the data to compare the hemato-chemical effects of pollution. the wbc,mcv,mch,ht,hb,glc,tp,and glo levels of fish in sari{dotless}çay creek were significantly higher than those in atikhisar reservoir (p<0.05). the rbc,tbil,chol,ast,and alt levels of fish in sari{dotless}çay were lower than the ones in atikhisar reservoir (p<0.05). there were no statistically significant differences in the mchc,tg,alb,ca,and p values among the fish samples of atikhisar reservoir and sari{dotless}çay (p>0.05). in conclusion,the data analyses infer that blood parameters can be used as an indicator of the fish health in general. on the other hand,the blood test can be used to determine fish stress due to water pollution.
