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.
The article is based on a FAO/UNDP consultancy on integrated fish farming in China, October-November 1981.
Seasonal floodplains under private and public ownership in the Indo-Ganges river basin provide food and income for millions of people in Bangladesh. Floodplain ownership regimes are diverse, covering the whole spectrum from public to private ownership. The paper compares community-based fish culture projects in these floodplains and analyzes the institutional arrangements of three different Floodplain Management Committees (FMC).
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.
A commercial breeding nucleus of coho salmon (Oncorhynchus kisutch) was established in Chile in 1997. This nucleus consists of two independent populations corresponding to different year-classes (even and odd, depending on the spawning year), which have been successfully selected for harvest weight (approximate genetic gain per generation of 10%). In order to constrain the buildup of inbreeding a strategy based on avoiding full-sib mating in each generation was used.
The IEIDEAS project, funded by the Swiss Agency for Development and Cooperation and managed by WorldFish and CARE in collaboration with the Ministry of Agriculture and Land Reclamation, has focused on the development of the Egyptian aquaculture value chain. In 2011, SDC and WorldFish conducted a value chain assessment.
Small-scale fisheries in and around rice fields in the lowland areas of Cambodia are greatly underestimated and undervalued. Their contribution to the protein requirements of the poor rural households is significant. In Svay Rieng province, they could provide 65-75% of the animal protein requirements of these households. The value could well be around 40% of the value of rice production. It is, therefore, important that these natural stocks and the fisheries are managed well and that developmental activities explicitly consider their impact on these fisheries.
