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.

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.
