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. La seizième réunion du Groupe de travail de la FAO sur l'évaluation des petits pélagiques au large de l'Afrique du Nord-Ouest s’est tenue à Dakar, au Sénégal, du 23 au 28 mai 2015. Le Groupe de travail a examiné l’état actuel des ressources de petits pélagiques en Afrique nord-occidentale et a fait des projections sur le développement de l’état des stocks ainsi que sur les futurs niveaux d’effort et de captures. -

No results found.The sixth meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Banjul, Gambia, from 2 to11 May 2006. This year, the Group made decisions on reference points for management of the pelagic stocks in the region. The advice for the stocks is given in relation to these reference points and on the basis of predictions for the next five years. The results of the assessments indicate that the stock of round sardinella is overexploited and co nsequently a decrease in effort in total sardinella fishery was recommended. The Atlantic horse mackerel was found to be probably fully exploited whereas the Cunene horse mackerel was found not fully exploited. Given that this is a mixed fishery, a decrease in the catches of horse mackerel was recommended. The mackerel was found not to be fully exploited, but given the mixed fishery with other species, it was recommended that the catches should not exceed 200 000 tonnes. The sardine stock in Zone A+B was found not fully exploited and the Working Group recommended not to increase catches above the average level of the last 5 years. The stock of sardine in Zone C was found to be underexploited and it was noted that the total catch level may be progressively increased during a five-year period. It was not possible to reach reliable conclusions from the assessments for bonga and anchovy, but in the case of anchovy acoustic estimates show an increasing biomass in recen t years. For bonga the catch rates are stable. The Working Group recommended as a precautionary measure that the catch level should not exceed the average over the five and three last years, for bonga and anchovy respectively. -

No results found.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.
