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 />

Score:<br />

80 (default score RBF on 1.1.1)<br />
