Tides rule the day for most mariners, who plan their work days based on its ebb and flow.
&ldquo;A tide book is like a Bible to a fishermen. It is constantly referenced &ndash; they lay their nets down by the tide, they launch by the tide &ndash; all their activity is centered around that every day,&rdquo; said Jerry Thompson of Soldotna, publisher of the Alaska Tide Book for 23 years.
