Fish protection for water intake structures

摘要

Water provides an important living environment for many creatures. Every intrusion poses a threat to what are often very fragile ecological systems. This statement is the starting point of a consideration of technical solutions for fish protection in the water intake process. EU guidelines (92/43/EWG) for protecting flora and fauna are the basis of every protection measure. Their appendixes define both areas worthy of protection (Appendix 2) and the animal and plant types (Appendix 4 and 5) to be protected. The fish described in Appendix 4 and 5 occur in almost all European waters.
