Table 6.  For the time periods within each year that were managed in the Mid-Coast and Massachusetts Bay Management Areas during 1 January 1999–31 May 2007, the number of harbor porpoises (HP) that would have been observed if the bycatch rate was exactly at the compliant rate of 0.031 observed harbor porpoises per observed mtons landed. 

Thus, the way to interpret this table is: in 1999 if there had been observed 0, 1, 2, or 3 harbor porpoises (whole numbers below the value in the last column) then the resulting bycatch rate would have been below the compliant bycatch rate, 0.031.
