The findings are presented of a literature survey conducted regarding research on Epinephelus culture. Information was obtained from ASFA for the period 1971-88, the ICLARM library and professional staff collections. Details are given of publication types, areas of research and some recent papers and research centres involved in grouper cultureare cited.
Over recent decades co-management has become an increasingly popular form of governance reform in many developing countries. Viewed as a means of promoting sustainable and equitable management of natural resources, it has seen wide application in small-scale inland fisheries. However, perhaps because of its worthy credentials, there has been insufficient critical assessment of the results. This paper commences with a review of underlying theory which is then used to explore the reasons for failure of a co-management initiative in Sri Lankan reservoir fisheries between 2001 and 2002.
Activities undertaken in the field of reef conservation are discussed in detail. Harvesting reef resources, national parks and protected areas, research and monitoring, and general management of coastal waters are covered. International initiatives are also considered.
Commencing with a summary of the current status, importance and productivity of natural wetlands the contribution of wetland ecological functions to sustaining vital ecosystem services is then reviewed. Provisioning services, notably fish and water for irrigation or domestic and industrial purposes constitute important benefits derived by humanity from wetlands, whilst recognition is growing that supporting, regulating and cultural services supported by wetlands are critical for sustaining social-economic systems and ensuring human well-being.
WorldFish and the International Centre for Climate Change and Development (ICCCAD) held a two-day workshop on the topic of Weather Index-Based Insurance: Lessons Learned and Best Practices for Bangladesh. Weather index insurance is based on a predefined weather event which when triggered ensures automatic payout to farmers who have taken out insurance. For example, the climatic trigger could be a predefined consecutive number of days where rainfall is below a set level or when the floodwater level reaches above a certain point.
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.
Settlement ponds are used to remove particulate and dissolved nutrients in Australian land-based aquaculture wastewater. At best, marine and brackish water settlement ponds reduce total suspended solids by 60%, but their efficiency is inconsistent. Functional improvements to nutrient removal systems are essential to provide uniform and predictable treatment of flow-through aquaculture wastewater. Furthermore, environmental regulation of discharge from intensive systems in Australia is increasing, providing the impetus to upgrade rudimentary single-step settlement pond systems.
The objectives of this study were first, to understand the market chain of fish as traded by women in the south-eastern Arm of Lake Malawi, with a specific focus on analyzing how fish is moved from the lake to the wholesale market. Secondly, the study identifies HIV/AIDS vulnerability factors along this market chain i.e. from the point of catch to the wholesale market.
In this chapter, the authors assess the vulnerability of aquaculture in the tropical Pacific to climate change. It begins by summarising recent and potential aquaculture production to set the scene for the sector, and then use the framework outlined in Chapter 1, based on exposure, sensitivity, potential impact and adaptive capacity, to evaluate the vulnerability of the main commodities for food security and livelihoods.
The primary factors that have caused the predicament of small-scale fishermen in India are discussed and recommendations are given.
