Comparison of paraoxonase activity,malondialdehyde and high-density lipoprotein levels in cultuvated normal and albino rainbow trout reared in the same conditions [Ayni{dotless} koşullarda yetiştirilen normal ve albino gökkuşaǧi{dotless} alabali{dotless}klari{dotless}ni{dotless}n paraoksonaz aktivitesi,malondialdehit ve yüksek yoǧunluklu lipoprotein seviyelerinin karşi{dotless}laşti{dotless}ri{dotless}lmasi{dotless}]

In this study,serum paraoxonase activity (pon),malondialdehyde (mda) and high-density lipoprotein (hdl) levels of culture rainbow trout (nrt) and albino rainbow trout (art) have been compared. in this research,art and nrt which have average weights of 130±10.7g and 150±11.9g respectively have been used. during the research,fish (art and nrt) have been fed with commercial trout feed,twice a day. fish used in the analysis have been random-ly caught from pools and five fish (three times replicated) for each group have been sampled. pon activity,hdl and pon/hdl levels determined in serum samples of nrt group have been found higher than the art group. mean mda level in nrt group has been found lower than the art group,however,these differences have been found statistically insignificant. finally,the different species and size,dominance status may be reason for the change of pon activity,mda and hdl levels.
