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.
Effects of stocking density on the growth, production, and economics of all-male tilapia (Oreochromis niloticus) were investigated in a rain-fed rice-fish ecosystem for a period of 120 days. Fish were stocked at the rate of 4000, 5000, and 6000 ha-1 in treatments T1, T2, and T3, respectively. Water quality was suitable for fish culture. Significantly higher growth was observed in T1 as compared to other treatments. SGR ranged from 1.26 to 1.51. Survival varied between 79% and 88% with treatment T1 producing the highest survival.
Throughout the world, poor fisheries management contributes to resource degradation, poverty, and food insecurity. This European Union project on an Ecosystem Approach to Small-scale Tropical Marine Fisheries is led by WorldFish and implemented in collaboration with national partners in Indonesia, the Philippines, the Solomon Islands and Tanzania. The overall objective is to use an ecosystem approach to fisheries management (EAFM) to improve governance of small-scale fisheries (SSF).
This report is an account of a cross-country study that covered Vietnam, Indonesia and the Philippines. Covering four sites (one each in Indonesia and Vietnam) and two sites in the Philippines, the study documented the impacts of three climate hazards affecting coastal communities, namely typhoon/flooding, coastal erosion and saltwater intrusion. It also analyzed planned adaptation options, which communities and local governments can implement, as well as autonomous responses of households to protect and insure themselves from these hazards.
In this paper, the authors present a methodology developed for gathering socioeconomic and environmental survey data in the field. The system is divided into two interfaces: i) an Android tablet with survey software for data collection in the field and ii) a back office application for questionnaire management and data compilation. Each of these technical components is detailed and the solutions to challenges and constraints that were faced are described.
This report summarizes activities carried out by WorldFish under Agreement CT09 Amendment No.2 dated 31 March 2010 between WorldFish and WWF, under the Coral Triangle Support Partnership (CTSP) project. The overall goal of the five-year CTSP project is “to improve the management of biologically and economically important coastal and marine resources and associated ecosystems that support the livelihoods of peoples and economies in the Coral Triangle”.
This paper reviews the coastal fishery resources of Bangladesh emphasizing the coastal environment, capture fisheries and management issues relative to the sector. Bangladesh’s Exclusive Economic Zone (EEZ) covers an area of about 166 000 km2. This area has abundant natural resources such as fish, shrimps, crabs and other marine products. Shrimp and fish trawling is the most important economic activity in this area. The fishery sector makes a significant contribution to the national economy in terms of foreign exchange, income generation and employment.
In rural Cambodia, fish is a source of food and income to millions of people. However, there has been a real threat to fish populations in natural wetlands due to the degradation of aquatic biodiversity and habitat, illegal fishing, increase of population and demand for fish, and the use of harmful pesticides for agriculture. The Rice Field Fisheries Enhancement Project (RFFEP) seeks to rebuild and protect the fish populations through innovative methods.
This report is intended to provide a range of background material in relation to Bangladesh and weather event forecasting, forecast information dissemination, and the implications of weather events and forecasting for communities and their livelihoods. It identifies where institutional efforts and funds have been, and are presently being focused, and ultimately makes some recommendations about CCAFS and WorldFish potential involvement/investment in these areas.
This brochure is part of a series that collectively detail how a community-based assessment of climate change was used in partnership with coastal communities and provincial and national-level stakeholders in Timor-Leste and Solomon Islands. The assessment contains four distinct, but related, steps focused on supporting community-level decision-making for adaptation through a series of participatory action research activities. Each brochure in this series details a specific activity in the four-step assessment.
