1.2 Harvest Strategy (management)<br />

1.2.1 Harvest Strategy:<br />

There is a robust and<br />

precautionary harvest<br />

strategy in place<br />

Scoring comments<br />

(1-60) The harvest strategy is<br />

expected to achieve stock<br />

management objectives<br />

reflected in the target and limit<br />

reference points.<br />

(2-60) The harvest strategy is<br />

likely to work based on prior<br />

experience or plausible<br />

argument.<br />

(3-60) Monitoring is in place that<br />

is expected to determine<br />

whether the harvest strategy is<br />

working.<br />

(1-80) The harvest strategy is<br />

responsive to the state of the<br />

stock and the elements of the<br />

harvest strategy work together<br />

towards achieving management<br />

objectives reflected in the target<br />

and limit reference points.<br />

(2-80) The harvest strategy may<br />

not have been fully tested but<br />

monitoring is in place and<br />

evidence exists that it is<br />

achieving its objectives.<br />

(1-100) The harvest strategy is<br />

responsive to the state of the<br />

stock and is designed to achieve<br />

stock management objectives<br />

reflected in the target and limit<br />

reference points.<br />

(2-100) The performance of the<br />

harvest strategy has been fully<br />

evaluated and evidence exists to<br />

show that it is achieving its<br />

objectives including being clearly<br />

able to maintain stocks at target<br />

levels.<br />

(3-100) The harvest strategy is<br />

periodically reviewed and<br />

improved as necessary.<br />

The harvest strategy for the sea bass fishery is designed to avoid growth overfishing and maximise recruitment to the adult stock by protecting<br />

bass smaller than 36 cm (see report section 3.1). There is a robust and precautionary strategy that has been in place and monitored for 20<br />

years, which has been demonstrated to have achieved its stock management objectives in UK waters in terms of yield per recruit and MSY.<br />

The performance of the harvest strategy has been periodically reviewed and evaluated, which has demonstrated that the growth overfishing that<br />

took place in the 1980‘s has ameliorated and there are no signs of recruitment overfishing.<br />

There are no target or limit reference points in terms of SSB and F for this stock, but the assessment team has not penalised the fishery for the<br />

absence of clearly defined reference points under this Performance Indicator, since the harvest strategy clearly uses an appropriate proxy for<br />

reference points. Instead, the harvest strategy is designed to achieve management objectives in terms of yield per recruit and MSY. These<br />
