Abstract
In close cooperation with the Norwegian sea-based aquaculture industry SINTEF has developed and tested a methodology for investigating fish-escape events. The study base was a review of a selection of investigation methods from other industries. Four different methods were tested through investigations of specific fish-escape events. An assessment of strengths and weaknesses of the individual methods related to requirements and framework conditions of the aquaculture industry followed. Important requirements for the investigation methods were that the methods should be adapted to the complexity and characteristics of the fish-escape events. In addition, it should be adapted to the size of the aquaculture company, and the available level of expertise and resources. A combination of two investigation methods were tested in a final workshop with a dedicated aquaculture company. The recommended methodology became a combination of the STEP method (Sequentially Timed Events Plotting) and a Causal map method. Positive feedback from the aquaculture companies during the testing proved applicability of the suggested methodology.
