Book (series)Technical studyThe use of ice on small fishing vessels 2003The use of ice on board smaller fishing vessels is increasing. One reason for this is the decrease in near-shore fish resources that is forcing the fishermen to make longer fishing trips and to conserve the catch on board during the trip. Another reason is the increasing demand for good quality fresh fish and the globalization of the markets for these products with increased quality control. This publication describes the requirements for the use of ice (and chilled seawater) on board fishin g vessels, from small insulated containers in dugout canoes, to refrigerated tanks on bigger vessels. It also gives an overview of the different types of ice plants and the ice produced in them. Chapter 1 describes the physical changes in fish exposed to heat, and how chilling the product delays these processes. Chapter 2 gives an overview of the different types of ice and chilled seawater and how they are produced. Chapter 3 describes the installation requirements for shore-based ic e plants and how the ice is stored and handled. Chapter 4 describes the on-board handling of ice and fish, including the advantages and drawbacks of the different types of ice and chilling systems. Chapters 5 and 6 give a description of the materials used for insulation and the design of insulated containers and fish holds. Finally, in Chapter 7 some calculations are given that can be used to estimate the quantity of ice needed for a fishing trip, and the volume of the fish hold. The publication is aimed both at fishermen who want more information about the different techniques used, and at boat owners and economic agents who want to invest in the use of ice to preserve the catches.

Book (stand-alone)Technical reportAgriculture mondiale: horizon 2015/2030. Rapport abrégé 2002Ce rapport constitue l'évaluation la plus récente de la FAO sur les perspectives à long terme de l'alimentation, de la nutrition et de l'agriculture dans le monde. Les projections concernent l'offre et la demande des principaux produits et secteurs agricoles, pêches et forêts comprises. Cette analyse sert de base à un examen plus détaillé d'autres facteurs, dont la nutrition et la sous-alimentation, et des conséquences pour le commerce mondial. Le rapport étudie également les répercussions futur es de l'offre et de la demande sur les ressources naturelles, et aborde la façon dont la technologie pourra contribuer à un développement plus durable. L'une des conclusions essentielles du rapport est qu'en l'absence d'actions correctives, l'objectif fixé par le Sommet mondial de l'alimentation en 1996 (réduire de moitié le nombre de personnes sous-alimentées d'ici 2015) ne saurait être atteint. A moins d'un effort massif d'amélioration des performances globales du développement, les probl èmes d'insécurité alimentaire les plus pressants continueront à peser sur le monde en développement. Les progrès à effectuer dans ce domaine dépendent de nombreux facteurs, et en particulier de la volonté politique et de la mobilisation de ressources supplémentaires. Les expériences du passé mettent en évidence le rôle crucial de l'agriculture dans le processus de développement, notamment lorsque la majorité de la population dépend de ce secteur pour ses emplois et ses revenus.

No results found.The document is a brief of showcase of a specific aquaculture innovation. It contains main information on the technique and approach used, scope and scale of application, accessibility and the outcome and benefits of the innovation. Rabbitfish are herbivorous fish native to the Indo–Pacific region. Most rabbitfish consumed currently come from capture fisheries. The high demand for these species is causing a decline in their numbers in the wild. Rabbitfish have considerable potential for small-scale sustainable aquaculture across Southeast Asia particularly in polyculture pond systems with milkfish, mud crab or shrimp. Rabbitfish feed low in the food chain, tolerate changes in temperature and salinity, and have non-aggressive behaviour, making culture of the species easier than most other marine finfish. Currently, there are very few hatcheries producing rabbitfish fingerlings and therefore the sustainable production of these species is in its infancy. Once a hatchery is established, this can serve as a hub to produce rabbitfish locally in a sustainable manner. Grow-out and marketing of rabbitfish can provide an alternative livelihood option for coastal communities.
