The frustrations encountered when trying to compare technical reports in which fishpond yield figures are reported in a variety of units (e.g., kg/ha, kg/pond, lb/acre, etc.) are familiar to most aquaculturists. However, severe problems may develop when trying to com¬municate research results to other audiences if data are transformed to a hectare basis. The authors gives his own experience in conveying research data to the farmers and the problem encountered.
Two means of reducing feed costs in semi-intensive aquaculture systems in the tropics are considered: economically optimal dietary protein levels and mixing feeding schedules.
This paper assesses factors influencing adoption of new shrimp aquaculture technologies within aquatic-agricultural farming systems in southwestern Bangladesh. The impacts of three new technologies were assessed: two Modified Traditional Technologies (MTT 1 and MTT 2) and a Closed System Technology (CST). A total of 789 farmers from 10 sub-districts in Khulna Division were surveyed randomly, including a control group of 350 farmers using traditional technologies.
India is endowed with a continental shelf of 0.5 million km2 and an exclusive economic zone (EEZ) of about 2 million km2. Almost half (39%) of the Indian population utilizes the marine fisheries resources. India ranked sixth worldwide in total fish production (4.95 million t) and second in inland fish production (2.24 million t) during 1995 - 96. Fish production expanded from 0.75 million t in 1950 - 51 to 4.95 million t in 1995 - 96, giving a significant increase at a cumulative growth rate of 4.2% per annum.
Small fish are a common food and an integral part of the everyday carbohydraterich diets of many population groups in poor countries. These populations also suffer from undernutrition, including micronutrient deficiencies – the hidden hunger. Small fish species, as well as the little oil, vegetables and spices with which they are cooked enhance diet diversity. Small fish are a rich source of animal protein, essential fatty acids, vitamins and minerals.
WorldFish Incubator is a new and innovative program designed to support investment into sustainable small and medium-sized aquaculture enterprises in developing countries. It identifies suitable projects and facilitates technical and financial assistance, offering nurturing in sustainable aquaculture through its network of contacts. By leveraging the benefits of scale, WorldFish Incubator will help the aquaculture sector deliver on its promise to meet the growing demand for fish whilst ensuring equitable supplies and access for the poor.
At WorldFish, we work with an extensive network of donors and partners to create change for the millions who depend on fish in the developing world. Partnerships are essential to bring technologies and innovations to scale and achieve development impact. By 2024, WorldFish and our donors and partners will improve the lives of 7 million direct beneficiaries and 23 million indirect beneficiaries.
Fish farming in Egypt is not formally recognized as an agricultural activity, so aquaculture cannot use water from irrigation canals. However, fish are raised as primary or secondary crops in combination with fruit and other plant crops. A study by the WorldFish Center found farms could efficiently use well water to intensively raise tilapia in aerated tanks and use the effluent to irrigate fruit trees, vegetables and flowers. Two other farms used water from nearby Nile irrigation canals to fill water storage reservoirs stocked with tilapia.
The WorldFish Center is implementing the FtF Aquaculture Project in 20 southern districts in Bangladesh. The project is implemented under USAID’s Feed the Future initiative in collaboration with the Government of Bangladesh.
This study was carried out to evaluate the value chain performance of the aquaculture feed sector in Egypt, in terms of value addition, employment and profitability. The strengths and weaknesses of each link of the value chain were assessed and appropriate upgrading, management and development strategies were suggested. Quantitative data were collected for each link in the value-chain through structured questionnaires that were drafted and distributed to the key players in the sector; 25 fish feed mills and 34 fish farms covering different geographical and production regions.
