No results found.This report gives an account of penaeid shrimp culture development work including postlarval production, nursery rearing and pond culture. The postlarval culture method was established for Penaeus monodon and P. merguiensis using different types of culture vessels. The total number of postlarvae produced in 1975 was 580 300 and production has increased to over 4 million in 1977; this figure will be rapidly increased in 1978 from induced gonad maturation and spawning. The highest P. monodon postl arvae per brood in a 10 m3 tank was achieved by producing 375 000 with 73 percent survival, and 320 000 with 52 percent survival for P. merguiensis. Mass-culture systems of phytoplankton and rotifers were established for larval food organisms. The particulated soybean curd and rotifers were used for the larval diet to substitute for Artemia nauplii. Artemia will still be needed for a better survival rate. Various types of nursery methods were experimented on formulated diet and on natural food in ponds; the optimal nursery stocking densities were determined. A series of pond culture results indicated that interim fish extermination by using 7 ppm derris root extract was effective. The annual shrimp production in pond projected from preliminary results indicated that 600 kg per ha per year is possible, utilizing natural productivity with the fertilization but no feeding. This phase of the work needs to be repeated. Based on the experiments, recommendations are outlined for f urther work to increase production. -
Book (stand-alone)Technical bookPromotion of Small-scale Shrimp and Prawn Hatcheries in India and Bangladesh - BOBP/REP/66 1994

No results found.The shrimp and prawn culture industries in India and Bangladesh still depend on wild fry. However, expanding production and the trend towards intensification, especially in India, will require the development of hatchery industries in these countries. Since the private sector is likely to be the engine for this development, BOBP undertook activities to transfer smallscale hatchery technology as directly as possible to this sector. In India, this took the form of training small-scale entrepr eneurs in tiger shrimp hatchery technology and providing financial support to the Government of West Bengal for the construction of a demonstration hatchery. Of eight trainees in India, one has set up a shrimp hatchery. The shrimp/prawn hatchery in West Bengal was completed, but not put into production. In Bangladesh, a small-scale demonstration freshwater prawn hatchery was set up in Chittagong District. A new hatchery technology, using brine and a simple recirculating biofilter, was found to be feasible. Both government and private sector participants were trained in the hatchery. Direct assistance in the form of training and equipment was given to four private groups. Three of them completed prawn hatchery construction by the end of 1993 and one of them went into production.

Book (series)FlagshipThe State of Food Security and Nutrition in the World 2021
Transforming food systems for food security, improved nutrition and affordable healthy diets for all
2021In recent years, several major drivers have put the world off track to ending world hunger and malnutrition in all its forms by 2030. The challenges have grown with the COVID-19 pandemic and related containment measures. This report presents the first global assessment of food insecurity and malnutrition for 2020 and offers some indication of what hunger might look like by 2030 in a scenario further complicated by the enduring effects of the COVID-19 pandemic. It also includes new estimates of the cost and affordability of healthy diets, which provide an important link between the food security and nutrition indicators and the analysis of their trends. Altogether, the report highlights the need for a deeper reflection on how to better address the global food security and nutrition situation.To understand how hunger and malnutrition have reached these critical levels, this report draws on the analyses of the past four editions, which have produced a vast, evidence-based body of knowledge of the major drivers behind the recent changes in food security and nutrition. These drivers, which are increasing in frequency and intensity, include conflicts, climate variability and extremes, and economic slowdowns and downturns – all exacerbated by the underlying causes of poverty and very high and persistent levels of inequality. In addition, millions of people around the world suffer from food insecurity and different forms of malnutrition because they cannot afford the cost of healthy diets. From a synthesized understanding of this knowledge, updates and additional analyses are generated to create a holistic view of the combined effects of these drivers, both on each other and on food systems, and how they negatively affect food security and nutrition around the world.In turn, the evidence informs an in-depth look at how to move from silo solutions to integrated food systems solutions. In this regard, the report proposes transformative pathways that specifically address the challenges posed by the major drivers, also highlighting the types of policy and investment portfolios required to transform food systems for food security, improved nutrition, and affordable healthy diets for all. The report observes that, while the pandemic has caused major setbacks, there is much to be learned from the vulnerabilities and inequalities it has laid bare. If taken to heart, these new insights and wisdom can help get the world back on track towards the goal of ending hunger, food insecurity, and malnutrition in all its forms. -

After shedding light on the nature of the challenges that agriculture and food systems are facing now and throughout the 21st century, the study provides insights into what is at stake and what needs to be done. “Business as usual” is not an option. Major transformations in agricultural systems, rural economies, and natural resources management are necessary. The present study was undertaken for the quadrennial review of FAO’s strategic framework and for the preparation of the Organization Medium-Term plan 2018-2021. -
