EXECUTIVE SUMMARY SWO-MEDeither in SSB or landing levels. Several countries have imposed technical measures, such as closed areas andseasons, minimum landing size regulations and license control systems. The EC introduced a driftnet ban in2002 and in 2003 ICCAT adopted a recommendation for a general ban of this gear in the Mediterranean [Rec.03-04]. Rec. 04-12 forbids the use of various types of nets and longlines for sport and recreational fishing fortuna and tuna-like species in the Mediterranean.In the past meetings, the Committee has reviewed the various measures taken by member countries and noted thedifficulties in implementing some of the management measures, particularly that of minimum landing size.SWO-MED-6. Management recommendationsThe Commission should adopt a Mediterranean swordfish fishery management plan with the goal of rebuildingthe stock to levels that are consistent with the ICCAT Convention objective. Until now, the Committee hasevaluated the technical measure for time-area fishing closures, which could initiate rebuilding, depending on theduration and timing of these closures. The Committee recommends the Commission to consider the adoption ofsuch measures which will move the stock condition to the level which will support MSY.Following the results from recent studies (de la Serna et al. 2006), technical modifications of the longline fishinggears, as well as the way they are operated, can be considered an additional technical measure to reduce the catchof juveniles. The Committee recommends that future work should consider a broader set of scenarios includingsuch modifications of the fishing gears, as well as fishing capacity reductions, minimum landing size regulations(MLS) and quota scenarios. However, the Group considers that MLS and quota might be difficult to implementin the Mediterranean swordfish fisheries. In addition, future analyses of management measures should includeeconomic aspects.MEDITERRANEAN SWORDFISH SUMMARYMaximum Sustainable Yield 14,250-15,500 1Current (2005) Yield 214,600 tCurrent (2007) Replacement Yield ~12,000-14,000 t 1Relative Biomass (B 2005 /B MSY ) 0.26-0.87 1Relative Fishing MortalityF 2005 /F MSY1.3 (0.6-2.5) 3F 2005 /F max2.9 (2.4->5) 4F 2005 /F 0.14.6 (3.7->5) 4F 2005 /F 20%SPR3.0 (2.6->5) 4F 2005 /F 30%SPR 4.2 (3.6->5) 4Management measures in effect Driftnet ban (Rec. 03-04)One month fishery closure in 2008 (Rec. 07-01) 51Range indicated is average estimates from production models and age-structured models. The uncertainty in the estimates is broader thanindicated.2 The 2006 reported catch is considered incomplete and too provisional to use in this table.3 Based on production model analysis using a long time series of catch effort data for which we have less confidence, range representsapproximately 80% confidence region for the model assumptions.4Based on age-structured analysis using a shorter times-series of catch effort data for which we have greater confidence, range representsapproximately 80% confidence region for the model assumptions.5 Various technical measures, such as closed areas, minimum size regulations and effort controls are implemented at the national level.121
