Abstract = {{The appropriateness of three official fisheries management reference
   points used in the north-east Atlantic was investigated: (i) the
   smallest stock size that is still within safe biological limits (SSBpa),
   (ii) the maximum sustainable rate of exploitation (F-msy) and (iii) the
   age at first capture. As for (i), in 45\% of the examined stocks, the
   official value for SSBpa was below the consensus estimates determined
   from three different methods. With respect to (ii), the official
   estimates of F-msy exceeded natural mortality M in 76\% of the stocks,
   although M is widely regarded as natural upper limit for F-msy. And
   regarding (iii), the age at first capture was below the age at maturity
   in 74\% of the stocks. No official estimates of the stock size (SSBmsy)
   that can produce the maximum sustainable yield (MSY) are available for
   the north-east Atlantic. An analysis of stocks from other areas
   confirmed that twice SSBpa provides a reasonable preliminary estimate.
   Comparing stock sizes in 2013 against this proxy showed that 88\% were
   below the level that can produce MSY. Also, 52\% of the stocks were
   outside of safe biological limits, and 12\% were severely depleted.
   Fishing mortality in 2013 exceeded natural mortality in 73\% of the
   stocks, including those that were severely depleted. These results point
   to the urgent need to re-assess fisheries reference points in the
   north-east Atlantic and to implement the regulations of the new European
   Common Fisheries Policy regarding sustainable fishing pressure, healthy
   stock sizes and adult age/size at first capture.}},
