Xenobiotic impact on Arctic charr: Nutritional modulation and physiological consequences

Updated 2000-10-05

The objectives are to test the hypothesis that the tissue re-distribution of PCB are linked to the metabolic status of the Arctic charr and that the tissue re-distribution of PCB associated with fasting will decrease the overall performance characeristics of the Arctic charr.

This is not a National Implementation Plan (NIP) project

Parameters and Media

Parameter groups measured/observed/modelled
Biological effects
Persistent organic pollutants (POPs)
Media sampled/studied/modelled
Freshwater fish
Additional information or further specification of types of data / information collected, species / tissues / organs sampled, etc.

The project are performed as an experimental study in which laboratory fish or wild fish are contaminated with relistic doses of PCB. Effect parameters include enzyme kinetics, metabolism, endocrine processes and immune status/disease resistance.


Regions studied
Persistent organic pollutants (POPs)

Methods & Procedures

Procedures and methodology used for, e.g., sampling and sample storage, sample pretreatment, extraction and analysis, including which laboratories are involved, references to methods employed, etc.

A number of laboratory methods are used for the analyses, including RIA and ELISA methods for hormone analyses, molecular methods for enzyme induction analyses. Disease resistance experiments with fish pathogens are performed in a certified fish disease laboratory in Tromsø.
