    The fourth session of the Scientific Advisory Group (SAG) of the Western Central Atlantic Fishery Commission (WECAFC) was held in Merida, Mexico, from 2 to 4 April 2007. Major topics discussed during the session were: the state of fisheries in the WECAFC region; the status and trends of fisheries and aquaculture; the decisions of the twenty-seventh session of the Committee on Fisheries (COFI) and the twelfth session of WECAFC; intersessional activities and projects; factors of unsustainability a nd overexploitation in marine fisheries; fisheries social science; and coordination and collaboration in fisheries science in the region. The decisions of the twenty-seventh session of COFI have implications for the work of WECAFC, especially in areas such as small-scale fisheries, subsidies, marine protected areas and bycatch reduction. The meeting identified weak management and poor governance as major problems in WECAFC member countries. Training and capacity building, to reinforce management , were identified as areas for donor support. The need for incorporating the human dimension in fisheries governance to ensure that outputs and outcomes contribute meaningfully to human well-being was highlighted.

    The seventh meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Agadir, Morocco, from 17 to 26 April 2007. The Group assessed the status of the small pelagic resources in Northwest Africa and made projections on the development of the status of the stocks and on future effort and catch levels. The advices for the stocks are given in relation to the agreed reference points F0.1, FMSY, B0.1 and BMSY and on the basis of the projections for the next five years. The results of the assessments indicate that the stock of round sardinella is overexploited and consequently a decrease in effort in the total sardinella fishery was recommended. The Atlantic horse mackerel was also found to be overexploited whereas the Cunene horse mackerel was found to be fully exploited. It was recommended that the effort in 2008 should decrease about 20 pour cent of the actual effort. The sardine stock in Zone A+B was found overexploited and the Working Group recommended to decrease the effort by 20 pour cent corresponding to a catch level of 350 000 tonnes in 2008. The stock of sardine in Zone C was found to be not fully exploited and it was noted that the total catch level may be temporarily increased, but should be adjusted to natural changes in the stock. The mackerel was found not to be fully exploited, the catches should not exceed in 2008 the current level of 200 000 tonnes. It was not possible to reach relia ble conclusions from the assessment models applied to bonga and anchovy but, in the case of anchovy, acoustic estimates show a decrease in biomass from 2005 to 2006. As a precautionary measure, the catch level for this species should not exceed the average over the last three years of 115 000 tonnes. For bonga, the recommendation from 2006 is maintained as no new information is available on this species, and the Working Group recommended that the catch level should not exceed 42 000 tonnes.
