Use of wastewater is an issue gaining importance throughout the (developing) world, as water sources become scarcer and competition for them increases. In Peru, research has shown the technical, economic and social feasibility of growing fish in wastewater. Such fish farms could recover 100% of the wastewater treatment costs.
There are 58 species of Clarias recognized in FishBase (as of January 2009), 33 in Africa and 25 in Asia. Aquaculture of clariids is important with 30 countries reporting a total production of over 300 000 t worth nearly US$400 million in 2006. Most production involves the African Clarias gariepinus (Burchell, 1822) and three Asian species, Clarias batrachus (Linnaeus, 1758), Clarias macrocephalus (Günther, 1864) and Clarias fuscus (Lacep'de, 1803). In much of Asia, hybrids of introduced C.
An endangered fish species in China, Reeves shad (Tenualosa reversii), is finding hope of restoration and conservation in aquaculture and induced breeding efforts spearheaded by the Yangtze River Fisheries Management Commission. The history and sensitive traits of the Reeves shad are described featuring the species' life history, population dynamics and management of the Reeves shad resources.
The study compares the socioeconomic profile of fish and nonfish farming households in three different agroecological regions in Zimbabwe. Some of the direct socioeconomic factors that influence the adoption of small-scale fish farming in the areas are also identified.
The great bulk of shrimp farming in India, as in most of Asia, as well as that of aquaculture in general in the region, is based on small scale farming activities, and in this regard, is no exception to other primary sector activities. The work on the development of better management practices (BMPs) on the shrimp culture sector commenced with the recognition of the need to place the sector on a firmer footing, while combating the problems of frequent disease occurrences, and to ensure its long term sustainability.
Sandfish is arguably the most commercially valuable of the tropical species of sea cucumber that are processed into bêche-de-mer. It is widely distributed throughout the Indo-Pacific, occurring in shallow inshore areas where it is easily accessible to coastal fishers. A-grade bêche-de-mer processed from sandfish commands some of the highest prices on the international market. But these same attributes also make it vulnerable to overexploitation. Sadly, this has happened in most places where it occurs.
In Bangladesh, only 6% of the daily food intake is animal food of which fish accounts for 50%. Rice is the mainstay, making up 60% of the daily food intake. However, many nutrients such as vitamins A and C, iron, calcium, zinc and iodine are not found in rice and have to be obtained from other sources. Small indigenous fish are a vital contribution to the diet of the rural poor in Bangladesh, where more than 30,000 children go blind every year from vitamin A deficiency and 70% of women and children are iron-deficient.
The WorldFish Center and the UN Food and Agriculture Organization (FAO) are currently implementing a Regional Programme entitled Fisheries and HIV/AIDS in Africa: Investing in Sustainable Solutions, to strengthen the capacity in the region to develop sustainable solutions to enhance the contributions of fish and fisheries to economic and human development. In particular, the programme is building a strategic response to HIV/AIDS in the fisheries sector that will generate benefits for vulnerable groups in wider society.
