Summary From the FIST application a pilot project evaluating existing escape barriers for safeguarding salmon hatcheries and identifying the ones suited for further development will be conducted. The issues are covered mainly by a revised WP 1. A more detailed background was given in the original application but a short summary is included here for completeness. The escape of farmed fish is one of the most important environmental challenges for the fish farming industry with respect to adverse genetic impact and contribution to the spreading of salmon lice. In addition it represents a considerable economic loss for the industry, estimated to 2 billion NOK by the Directorate of Fisheries in 2004. Currently the most common escape barriers are combinations of nets and gratings, however over the years research on several other options have been investigated. Researchers at the Department of Engineering Cybernetics (DEC) at the Norwegian University of Science and Technology (NTNU) have developed and studied several alternatives to traditional fish barriers and new methods of manipulating fish behaviour in general (Balchen, 2000). One of the techniques which may prove useful in context of the FIST project is the electrical fish barrier which employs electrical fields in combination with / or instead of physical obstructions to restrain the fish. Using a mechanically non-obstructive barrier has a clear advantage over a physical barrier in terms of less vulnerability to debris and fouling matter, and, consequently, reduced maintenance costs; however it requires rigorous safety measures. A combination of vision technology and a mechanical collection system is another option that combines technology with mechanical barriers. Environmental considerations will also be an important measure, as a double barrier will be an excellent opportunity for a better control system of the effluent water and its water quality. Fish welfare will also be an important consideration
