AB  - In order to ,issess effects of environme ntal pollutants on aqu at ic ecosystem s, different biomarkers may be exa mined.  The  pha se  I  biotransforma t ion e nzymes, notab ly CYP l A, definitely belong to t he most sensitive fish biomarker s known at present. CYP l A is a well-established biomarker  of  exposure  of  fish  to  xenobiotic  compounds.  The  CY P l A  protein  le vels can  be  determined  immunologicaly  ,  using   mono-   or polyclonal  antibodies  with  ELISA,  Western-blotting   or   histochemic  al technique  s.  Generally,  a  good  correlation  is  observed  between  CYP I A mRNA , protein le ve l s and CYP I A activity.  ln  this  work  we  per fo rm ed Weste r-b lot analys is and our aim was to characterize the  in du c ti on  of  CYPIA in he patopanc reas of the  European  hake-Merluccius mer /ucc ius and Red mul let-Mu l/us barbatus and in  winter  and  spring  at  the  mouth  of  th e river  Bojana.  Both  species  are  of  considerable  commercial  import ance Whereas intersp ecies differences in protein profiles were established, no qualitative  or  quantitative  intraspecies  or  seasonal  variations  in  protein  profiles were observed. Western blot analysis with a polyclonal antibody to  CYP1A reve aled the CYP I A expression in both  examined  fish  species  in winter  at  the  very  low  level.   However,   the   relative   concent!"ations   of CYP I A were increased in sprin g. The apparent initiation of  the  defens e response in fish  suggests  that  the  contamin  ants  present  in  seawater  have  an eco toxico logic al potentia l. These findings could be interpreted as an ea rly­ warning  signal for the deleter ious effects  of  the  pollutants.  The  higher  le vel of CYP l A in spr in g could  be connecte d with increased antopo genic ac ti v ity at the mouth  of  the  river Bojana  in  this  part  of the year.
