The marketing system for sea cucumber in South-East Asia is generally inefficient, and marketing channels are multilayered. Information asymmetry encourages proliferation of redundant players in the distribution system, while high transaction costs keep the overall marketing margin high but the price received by collectors low. This paper is limited to establishing the major features of the marketing system for sea cucumber in South-East Asia.
Details are given of trials conducted in Thailand using the "hapa" system for nursing fish fry to fingerlings of the desired size for use in small scale aquaculture operations.
Aquaculture is widely held to contribute to poverty reduction and food security in the Global South, but robust evidence is limited. Using nationally representative data from Bangladesh, this study analyses changes in fish consumption from 2000 to 2010. Rapid expansion of commercial aquaculture pegged down fish prices, resulting in increased fish consumption by extreme poor and moderate poor consumers and those in rural areas. These outcomes are closely linked to the pro-poor nature of national economic growth during this period.
Integration of aquaculture with agricul¬ture (integrated farming) provides balanced food production, increases farmers' income, recycles nutrients, protects the environment and optimizes food production where resources are limited. Zimbabwe is a land-locked country with abundant resources in the form of dams, lakes, streams, rivers and groundwater. The rationale for development of integrated farming in Zimbabwe is given.
This report presents the findings of a mission to critically review the institutional, policy and regulatory framework for sustainable development of the Egyptian aquaculture sector. The study was undertaken by an International Expert on Aquaculture Policy, and a National Expert on Institutions, on behalf of the Project “Improving Employment and Income through the Development of Egypt’s Aquaculture Sector“, implemented by WorldFish and CARE, and funded by the Swiss Agency for Development and Cooperation(SDC).
Bivalve culture in Thailand is discussed, describing pilot hatchery operations at Prachuap.
Poor rural consumers benefit from Egypt’s aquaculture sector through access to small and medium-sized farmed tilapia sold by informal fish retailers, many of whom are women. In fact, informal fish retail is the main, if not only, segment of the farmed fish value chain where women are found. This report aims to inform current and future strategies to improve conditions in informal fish retail by understanding in more depth the similarities and differences in employment quality and outcomes across different fish retailers.
Social interactions often occur among living organisms, including aquatic animals. There is empirical evidence showing that social interactions may genetically affect phenotypes of individuals and their group mates. In this context, the heritable effect of an individual on the phenotype of another individual is known as an Indirect Genetic Effect (IGE). Selection for socially affected traits may increase response to artificial selection, but also affect rate of inbreeding.
Through a SIDA -funded project on small-scale fisheries FAO and partners have been supporting WorldFish Center research into small-scale aquaculture investment. Studies of projects in Bangladesh, India and Indonesia suggest significant outcomes from investment, and start to show the potential for new avenues for investment in aquaculture that have potential to deliver not only aquaculture products and profitable businesses for smallholders, but also social and economic goals. Some of the highlights are provided in this article.
Fish—including finfish and shellfish—are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than 75 percent of the world’s fish consumption occurs. In addition to protein, fish contain micronutrients and longchain omega-3 fatty acids that are essential for maternal and child health, but often deficient in the diets of the poor.
