1.2.4 Assessment of stock<br />
status: There is an<br />
adequate assessment<br />
of the stock status<br />
(1-60) The assessment<br />
estimates stock status relative to<br />
reference points.<br />
(2-60) The major sources of<br />
uncertainty are identified.<br />
(1-80) The assessment is<br />
appropriate for the stock and for<br />
the harvest control rule, and is<br />
evaluating stock status relative<br />
to reference points.<br />
(2-80) The assessment takes<br />
uncertainty into account.<br />
(3-80) The stock assessment is<br />
subject to peer review.<br />
(1-100) The assessment is<br />
appropriate for the stock and for<br />
the harvest control rule and<br />
takes into account the major<br />
features relevant to the biology<br />
of the species and the nature of<br />
the fishery.<br />
(2-100) The assessment takes<br />
into account uncertainty and is<br />
evaluating stock status relative<br />
to reference points in a<br />
probabilistic way.<br />
(3-100) The assessment has<br />
been tested and shown to be<br />
robust. Alternative hypotheses<br />
and assessment approaches<br />
have been rigorously explored.<br />
(4-100) The assessment has<br />
been internally and externally<br />
peer reviewed.<br />
Scoring comments<br />
There is an assessment methodology for evaluating sea bass stock status relative to the reference points defined in the harvest strategy (yield<br />
per recruit and MSY), which takes account of all of the major features relevant to the biology of the species and the nature of the fishery. The<br />
assessments take uncertainty into account, and have been subject to peer review (Kupschus,et al., 2007 and Kupschus, 2010, by ICES), and<br />
published (Pawson et al., 2005; Pawson et al., 2007b). These models are considered appropriate for the stock by ICES SGBASS and WGNEW<br />
The assessment team notes, however that the most recent assessments of this stock (Kupschus et al., 2007, Kupschus 2010) are thought to be<br />
increasingly uncertain, other than in terms of trends in SSB. Consequently, the stock status at present is uncertain.<br />
