4 Responsible Sourcing Guide: Hake. Version 6 – March 2012 Management Stock (colour coded to map) Agreed TAC 2012 (t) Advis’y TAC 2012 (t) Scientific advice and management Category 1-3. Inside safe biological limits North Pacific hake (Pacific whiting: Merluccius pruductus) 393,751 (2011) 757,738 (2011) The latest assessment in 2011 indicated a stock that is abundant and not overfished (8,11). The 2008 year class is estimated, with some uncertainty, to be very large, indicating good prospects for the fishery. Fishing mortality is below the target level. There are measures to reduce by-catch of other species. One MSC certified fishery (4). South African shallow water cape hake (M. capensis) European hake, (Merluccius merluccius) northern stock: ICES Division IIIa, Subareas IV, VI, and VII, and Divisions VIIIa,b,d. 28,869 28,869 South African cape hake are assessed as two separate stocks. Spawning Stock Biomass (SSB) of M. capensis has been well above B MSY-trigger for 30 years (12). This indicates a healthy population that is not overfished. The TACs are set using an operational management plan that uses time series of both commercial and survey catch per effort data to forecast on future catches. One MSC certified fishery (4). 55,105 (13) (13), 51,900 All EU waters combine d A new length-based assessment method and extension of the modelled time period back to 1978 has improved the quality of the assessment and reduced uncertainty in estimates of SSB and fishing mortality (10). There have recently been several high recruitments and SSB has increased since 1998 and is estimated to be record high in 2011. Though fishing mortality has been decreasing in recent years, it is still above F MSY . A recovery plan agreed by the EU in 2004 (14) is scheduled to be replaced by a long-term management plan (15) aiming towards MSY. ICES’ advice is given on the basis of the transition towards the MSY framework. Cat 4. Stocks at risk of being outside safe biological limits and below biomass action point B MSY-trigger South African cape hake Deep-water (Merluccius paradoxus) 115,580 115,580 The SSB of M. paradoxus has improved since 2007, but was still below B MSY-trigger in 2011. An Operational Management Plan (see M. capensis) is in place to allow the recovery over 20 years (12). One MSC certified fishery (4).
5 Responsible Sourcing Guide: Hake. Version 6 – March 2012 Management Stock (colour coded to map) Agreed TAC 2012 (t) Advis’y TAC 2012 (t) Scientific advice and management Category 5. Stock outside safe biological limits. Argentine hake Merluccius hubbsi Northern stock, North of 41 o S Argentine hake Merluccius hubbsi southern stock South of 41 o S Preuvian hake Merluccius gayi peruanus Chilean hake Merluccius gayi gayi Patagonia Merluccius australis 60,000 40,000 Spawning Stock Biomass (SSB) has been below the safe biological limit since 1998 and shows no signs of improvement, and fishing mortality in 2010 was more than twice the target for recovery. The catch recommendation is intended to restore SSB levels, but TACs are set higher that advised and there is substantial mis-reporting (16). 273,000 238,000 SSB has been below the safe biological limit since 2008 and fishing mortality is above the target for recovery. Although the stock is considered to be in poor condition, TACs have been set in excess of advice in recent years (16). 40,000 (2011) 40,000 (2011) SSB has recently recovered to around safe biological limits, but the current fishing mortality is 3 times the target (16). 45,000 33,000 The current stock abundance is slowly recovering but SSB has been outside safe biological limits since 2004. Although the set TACs have been above the advised TACs in recent years, the actual catches have been lower and fishing mortality is below the target. Technical measures to protect juvenile fish and closures for stock recovery have been introduced. Industry has established a protocol for responsible fishing (16). 23,000 22,000 The stock has declined over the past 10 years to its lowest recorded level, but estimated to be just inside safe biological limits. Fishing mortality has been above the recommended level for 9 years (16). Category 6. Reference points not defined Namibian cape hakes (Merluccius paradoxus & Merluccius capensis) European hake (Merluccius merluccius) Southern stock ICES division VIIIc, IX and X European hake Mediterranean 145,000 The status of the Namibian stock is uncertain. Stock status reports have not been published since 2004 and produced conflicting results (16). 19,373 12,299 (13) 29,841 (FAO 2009) 14,300 Included in EU total No TAC advised Recruitment has been high since 2005 and SSB has increased consistently since 1998, but its status relative to any potential biomass reference points is unknown. Fishing mortality has been stable over the last decade and is well above F MSY (10). A recovery plan agreed by EU in 2005 (15) has not been evaluated by ICES, which provides advice on the basis of a transition to the MSY approach, on the assumption that SSB in 2012 will be above any potential candidate for B MSY-trigger .
