The bottom feeding fish species have a good potential to be used for
assessments of pollution, as they are under pressure from pollutants
from both water and sediments. In this study, the level of similarity of
histopathological responses to pollution in gills and liver between
barbel (Barbus barbus) and sterlet (Acipenser ruthenus) from the Danube
River was assessed, and compared with elemental concentrations in their
gills, liver, and muscle. Results indicate that the detected metal
concentrations were likely cause of different tissue responses in gills
and liver of the two investigated fish species. Statistical analysis
indicated a clear differentiation of the two species based on elemental
concentrations and the level of histopathological changes in gills and
liver. Metal concentrations exceeded maximum acceptable concentrations
in a number of analyzed specimens, which indicates the importance of
this type of monitoring. Results indicate that barbel is a better
indicator for specific, rather narrow sites, whereas sterlet is a better
indicator of larger (longer) water current segments. Obtained
information could be of importance for both scientists and fishery and
water management authorities working on the development of water
monitoring programs. (c) 2014 Wiley Periodicals, Inc. Environ Toxicol
