The proponents have some interesting ideas, but the technical background was poorly explained. A brief summary of the existence of a book on salmon rhythms and the presentation of related hypotheses within the region was presented. The concept of using light as a cue for a variety of practical applications in the salmon-hydrosystem is tempting, but based on the information in the proposal not enough evidence is presented to justify investment in the development of the models. Therefore, the ISRP believes the proposal is not fundable at this time.
