Effect of Electric Fish Barriers on Corrosion and Cathodic Protection
Project ID: 4805
Principal Investigator: Daryl Little
Research Topic: Fish Passage and Entrainment
Funded Fiscal Years: 2015
Keywords: cathodic protection, corrosion, fish barrier, electric crowder, graduated field, interference
Will electric fish barriers have an adverse effect on the corrosion of nearby structures? Can potential interference issues be created between cathodic protection systems and electric fish barriers affecting the operational electrical fields of either?
Need and Benefit
A main goal of Reclamation is the delivery of water and power. However, endangered and protected fish species may be affected by this water delivery system. Electric fish barriers can be used to control the movement of fish, thereby protecting them from adverse outcomes due to Reclamation projects. Corrosion though is also an issue in many of these bodies of water and therefore must be protected, often with some type of cathodic protection system. Interference can be extremely detrimental to both corrosion mitigation and controlling the movement of the fish.
