Methodological recommendations for quantifying the risk of injury and mortality to fish during the passage of hydropower sites
The key messages of Fact Sheet No. 03 are:
- Studies to determine the risk of injury to fish at hydropower sites should consider the comparability of results.
- This requires a minimum of methodological standardisation. A uniform protocol for recording injuries is a basic prerequisite for this.
- Experimental studies with, individually marked fish guarantee reliable data and a high degree of comparability
