Tilapia lake virus (TiLV): What to know and do?

Tilapia lake virus is a newly emerging virus that is associated with significant mortalities in farmed tilapia. With cases reported across Africa, Asia and South America, the virus represents a huge risk to the global tilapia industry, whose 2015 production was valued at USD 9.8 billion. All countries with a tilapia industry must be vigilant and act quickly to investigate cases of mortalities in farms.

The 'seafood gap' in the food-water nexus literature--issues surrounding freshwater use in seafood production chains

Freshwater use for food production is projected to increase substantially in the coming decades with population growth, changing demographics, and shifting diets. Ensuring joint food-water security has prompted efforts to quantify freshwater use for different food products and production methods. However, few analyses quantify freshwater use for seafood production, and those that do use inconsistent water accounting. This inhibits water use comparisons among seafood products or between seafood and agricultural/livestock products.

Identifying opportunities to improve governance of aquatic agricultural systems through participatory action research

Challenges of governance often constitute critical obstacles to efforts to equitably improve livelihoods in social-ecological systems. Yet, just as often, these challenges go unspoken, or are viewed as fixed parts of the context, beyond the scope of influence of agricultural, development, or natural resource management initiatives. What does it take to get governance obstacles and opportunities out in the open, creating the space for constructive dialogue and collective action that can help to address them?

Conflict and collective action in Tonle Sap fisheries: adapting governance to support community livelihoods

This paper presents the results of action research conducted from 2009 to 2015 on the dynamics of resource conflict concerning fisheries and livelihoods in the Tonle Sap Lake, as well as the institutional context and strategies for institutional adaptation to address such conflicts equitably.

A new professionalism for agricultural research for development

There have been repeated calls for a ‘new professionalism’ for carrying out agricultural research for development since the 1990s. At the centre of these calls is a recognition that for agricultural research to support the capacities required to face global patterns of change and their implications on rural livelihoods, requires a more systemic, learning focused and reflexive practice that bridges epistemologies and methodologies.

Growth and economic analysis of freshwater prawn, Macrobrachium rosenbergii (de Man), produced with feeds substituting sunflower cake for fish meal, soya bean meal and mustard oil cake

Prawn farming has grown in popularity since its introduction to Bangladesh in the early 1980s and is now widely practised in coastal areas. In Bangladesh, the main fish feed ingredients for prawn farming are rice bran, maize, soya bean meal, mustard oil cake, fish meal and meat and bone meal. This study was designed to evaluate the suitability of variable concentrations of low-cost oil-extracted sunflower cake in the diet for freshwater prawn M. rosenbergii in freshwater gher aquaculture system of Southern Bangladesh.

WorldFish incubator: Investing in sustainable aquaculture through SMEs

WorldFish Incubator bridges the gap between scientific research and business by supporting investment in sustainable small- and medium-sized aquaculture enterprises in Africa, Asia and the Pacific. By building opportunities for growth, WorldFish Incubator connects small-scale aquaculture enterprises in Africa, Asia and the Pacific with investors seeking scalable, high-impact, bottom-line investments in aquaculture.

A workshop on length-based methods in fisheries analysis in the Solomon Islands

A brief account is given of a workshop organized by the South Pacific Research Coordination Unit of the ForumFisheries Agency in order to examine the use of length frequency data as a tool in fish population assessment in the South Pacific region. The workshop concentrated on the ELEFAN suite of programmes and length frequency data for species from a variety of taxa and habitats were analyzed.
