ABSTRACT

 

There is a need for sensitive bio-monitoring tools in toxicant impact assessment to indicate the effect of toxicants on fish health in polluted aquatic ecosystems. Histopathological assessment of fish tissue allows for early warning signs of disease and detection of long-term injury in cells, tissues, or organs. The aim of this study is to assess the degree of histopathological alterations of various organs in various fish species in different environmental conditions. Histopatholoigcal lesions in fish served as primary indicators of exposure to contaminants and certain diseases and lesion types have proven to be reliable biological indicators of toxic/carcinogenic effects resulting from such exposure. Use of histopatholoigcal techniques allows investigators to examine specific target organs and cells as they are affected by exposure to environmental chemicals. Moreover, it offers a means of detecting acute and chronic harmful effects of exposure in the tissues and organs of individual animals. The present study reviews the most important histo-cytopathological alterations in various organs of fish, which have been used as biomarkers in different international pollution monitoring programs. This review provides information concerning the exposure, effects and susceptibility of fish in the context of environmental monitoring and the biomarker approach. As such, it provides a powerful integrative tool for the assessment of biological effects of contaminants in these environments.
