No results found.The eighth meeting of the FAO Working Group on the Assessment of Small Pelagic Fish off Northwest Africa was held in Saly, Senegal, from 6 to 15 May 2008. 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 nex t five years. With the exception of sardine (Sardina pilchardus) in Zone C, the other small pelagic fish stocks in the region are considered to be fully or overexploited. Sardine in Zone C does not show signs of overexploitation and the estimated biomass index from the regional survey (November–December) increased in 2007 as compared to 2006. Nevertheless, given the fluctuations observed in the abundance of this stock care should be taken in its management. The situation for the sardine stock in Zone A+B seems to have improved since 2006 and this stock is now considered fully exploited. Cunene horse mackerel (Trachurus trecae) was found to be fully exploited, and the recruitment survey index suggests a good recruitment for 2007. The stock of Atlantic horse mackerel (Trachurus trachurus), despite the observed increase in the biomass index estimated by the regional acoustic survey, is still considered overexploited. Because horse mackerel fishery in parts of the zone does not separate the two species, an overall reduction of effort on these species was recommended. Round sardinella (Sardinella aurita) and chub mackerel (Scomber japonicus) were found to be overexploited and effective management measures will be required to promote their recovery to a productive state. -

Book (stand-alone)Technical book玉米田草地贪夜蛾 综合防治
非洲农民田间学校指南
2020Also available in:
草地贪夜蛾(Spodoptera frugiperda)是一种原产于美洲的危险跨境害虫，自2016年起迅速传入非洲所有区域，给作物造成巨大损害。农民教育和社区行动是采用综合生态害虫管理方法防治草地贪夜蛾种群最有效管理战略的关键要素。农民田间学校(FFS)是一个已经在90多个国家使用的综合农民教育方法，将成为应对草地贪夜蛾防治工作的重要手段。 本指南旨在就如何在非洲草地贪夜蛾综合及可持续管理方面开展农民田间学校工作进行指导，并以玉米围绕草地贪夜蛾为重点。本指南介绍草地贪夜蛾生物学和生态学，以及为期一季的农民田间学校采取的田间试验和练习，并针对如何为草地贪夜蛾农村咨询服务/推广而设计培训计划，和农民田间学校骨干培训师和辅导员的进修课程提出了建议。 -
