Bioindicator in rivers and lakes

The bream is a species of fish which lends itself particularly well as a specimen type for the Environmental Specimen Bank on the grounds of its numbers, widespread presence and substantial biomass availability.

Muscle and liver are used as a specimen. Sampling takes place in the late summer after the spawning season.

For more information about the specimen, the sampling and the processing of samples see the Guideline for Sampling and Sample Processing Bream (Abramis brama).

Target organs/Matrices

  • Musculature
    The musculature or muscles are the eatable part of the fish and therefore are directly linked to the human food chain.
  • Liver
    The liver is the main reloading point of the substances within the body. Thus the liver is suitable for surveying eco-toxicological relevant components.
  • Blood plasma
    As a liquid component of the blood, blood plasma is responsible for the transport of numerous components, such as fats, hormones and proteins. In terms of quantity, it makes up the largest part of the blood.
