Fraser River sockeye salmon: data synthesis and cumulative impacts

ased on time or other stocks) to ‘fill in’ the dataset and therefore reduce the number ofdata points that had to be dropped from the analysis. In the end this strategy was rejectedbecause data sets with only small gaps only resulted in a small loss of data and data setswith larger gaps (often at the beginning or end of the data set) were not able to be ‘filled in’with confidence. We have re-written the description of how we handled ‘missing data’ in4.7 as well as in Appendix 3.26. Page 78 - The table suggested above should define what is meant by "Threeadditional models were tested with the model set...", the "all marine model", and otherequally vague terms.Response: This section has been completely rewritten. Please refer to the response for #24.27. Section 4.7.3 on pp. 79-80 - A summary table is also necessary here.Response: This section has been completely rewritten. Please refer to the response for #24.28. Page 81 - In the last two paragraphs prior to section 4.8, you bring in pink salmondata without describing what types of mechanisms the PSC workshop concluded wereplausible. Here the reader will have no idea whether you are talking about competitionor predation by pinks. The last sentence prior to section 4.8 talks only in vague termsabout the mechanism; it must be more explicit.Response: We have revised this paragraph, providing more details on the hypothesesevaluated in the PSC report.29. Page 86 - what do you mean by "database assimilation"?Response: We have rewritten this line to clarify the intended meaning, that collected datawould be assimilated into a central, integrated database.30. Page 87 - An intriguing, but to me, impractical suggestion is made here: "... continueexisting topic-specific databases (e.g., climate data, ocean conditions, stockinformation, contaminants, habitat data, disease), each maintained by the entities thathave collected these data, but link key fields of each one to an integrated,interdisciplinary, geo-referenced database." The footnote to this idea notes that theTrinity River Restoration Project is moving in this direction. It would be worth expandingupon that example here to demonstrate that the suggestion made by the authors in thequote above is achievable.Response: We have expanded our description and included some discussion of thechallenges involved with integrated but regionally distributed databases.31.
