Histological and chemical assessment of mercury-induced liver damage in Brosme Brosme from the Sognefjord

 

Project duration: 2018

Project description:

Mercury is found in most aquatic environments, including freshwater and seawater and impacts the health of aquatic animals by bioconcentration and bioamplification which in turn affects the entire food chain. It is also well known that exposure of fish to deep waters and sediments enhances exposure to mercury.

The goal of this study is to assess for detrimental signs of mercury on the liver of the deep water fish, Brosme brosme, and compare the liver quality to liver of surface fish as Gadus morhua and Pollachius pollachius.

To reach this goal, fish will be collected by fishing with net and longline in the Sognefjord (Norway). A proprietary preliminary technique for quantifying mercury in the liver oil will then be used to confirm that the Brosme brosme has a higher mercury content in the liver than surface fish as Gadus morhua or Pollachius pollachius. The histology analysis of the liver will then be carried out to identify eventual cellular structure differences between fish with high and low levels of mercury contamination of the livers.

The most interesting and challenging part of this project lies in the study of the fish in their natural conditions, without a reference control as is normally arranged in any laboratory experiment. Nevertheless this result can help to better understand how mercury affect living being in their natural environment.
