Water quality. Biochemical and physiological measurements on fish - Sampling of fish, handling and preservation of samples Ingestion-build-48183 Acoustics - Rating of sound1 Scope This part of ISO 23893 provides guidance on how to sample fish for determination of biochemical and physiological characteristics, such as the composition and enzyme activities of blood, liver, muscle and other tissues in order to asses the health of fish in the field as well as in the laboratory. The biochemical and physiological variables used for this purpose are often called biomarkers. This part of ISO 23893 includes recommendations and
