Ruggerone Publications

I have place several publications on this web site at the request of fishermen and the salmon industry, who do not have easy access to journal publications. Copyrights of some publications belong to the journal, which is noted on each pdf file. For example, the Canadian Journal of Fisheries and Aquatic Sciences is published by NRC Press (http://pubs.nrc-cnrc.gc.ca/cgi-bin/rp/rp2_desc_e?cjfas). You may download the pdf file for personal use or you may contact me by email if the file is not available here. Additional papers will be added in the near future. 9/20/2006. Ruggerone@comcast.net
