14pgs, We used an online survey to document challenges experienced by aquaponic hobbyists (n = 81), producers (n = 117), and educators (n = 75). Responses were distilled into the following categories: 1) operations and management; 2) facilities, location, and system design; 3) knowledge and educational resources; 4) funding; 5) economic viability; 6) plant culture; 7) marketing and distribution; 8) fish culture; 9) human factors; 10) regulations and certifications. Training and research in these areas are needed to advance the aquaponics industry.

27 pages., Authors provide an overview of recent and forthcoming global datasets and explore the challenges of translating these new analyses into policy action and on-the-ground conservation of mangrove forests. They describe a new platform for visualizing and disseminating these datasets to the global science community and other audiences - and they highlight future directions and collaborations.

8 pages, The role of information in agricultural development cannot be overemphasized, as information is vital in increasing production, improving marketing and enhancing distribution strategies. Therefore, the study examined the impact of information communication technologies on the technical efficiency of fish farming in Ogun State, Nigeria using a stochastic production frontier approach. In a cross-sectional survey, a multi-stage sampling technique was employed to elicit primary information from 120 fish farmers. Major ICT sources used by the fish farmers include television (81.7%), radio (79.2%) and the Internet (68.3%). The average output of catfish has positive and significant elasticity with regards to each input variable except family labour. The inefficiency model revealed that the age of farmers, farming experience, television and radio usage were significant but negatively related. That means that any increase in any of these factors will reduce the inefficiency of fish farmers and bring about an increase in technical efficiency. This implies that it is possible to increase technical efficiency in fish farming in the study area provided that the media channel (radio and television) predominantly used is improved. This study recommends a reduction in family labour usage while at the same time encouraging young people to venture into fish farming.

6 pages., via Scientific American website., Demand for seafood is increasing across the globe, and the United States is no exception. Aquaculture, or aquatic farming, is increasingly meeting this demand and now supplies just over 50 percent of all seafood globally. In fact, it has been one of the world’s fastest growing food sectors for years.
30 pages, via online journal, Environmental journalists, as gatekeepers, often become arbiters of risk and benefit information. This study explores how their routine news value judgments may influence reporting on marine aquaculture, a growing domestic industry with complex social and ecological impacts. We interviewed New England newspaper journalists using Q methodology, a qualitative dominant mixed-method approach to study shared subjectivity in small samples. Results revealed four distinct reporting perspectives—“state structuralist,” “neighborhood preservationist,” “industrial futurist,” and “local proceduralist”—stemming from the news value and objectivity routines journalists used in news selection. Findings suggest implications for public understanding of, and positionality toward, natural resource use and development.
Using two samples of U.S. adults (Study 1: N = 336; Study 2: N = 2329), this study features a messaging experiment utilizing a between-subjects design, with a no-message control group, to explore the impact of a narrative video, in comparison to an infographic video, on support for sustainable aquaculture. Results indicate that the infographic video type is more transporting than the narrative video, and that transportation influences support for aquaculture indirectly through emotional response, as well as risk and benefit perceptions; however, importantly, we also note that video content may have contributed to the observed differences. For an emerging issue like aquaculture with environmental and human health implications, strategic messaging, especially when accompanied by vivid images, may allow audiences to better engage with a complex and contentious topic.

6 pages, Numerous approaches can be implemented to carry out on-farm Extension demonstrations in aquaculture. The design and approach used are often governed by the problem or question that needs to be addressed as well as budgetary constraints within Extension programs. West Alabama is home to a unique inland marine shrimp industry that uses a low-salinity artesian groundwater source to raise shrimp. Demonstration and technology transfer have been carried out on commercial shrimp farms for nearly 20 years using low-budget on-levee tank systems operated by Extension personnel using this unique water source. On-farm tank demonstrations can be an effective tool for Extension professionals working in aquaculture, especially where unique circumstances exist.
8 pages, via online journal, Dense networks of rivers, canals, ditches, dikes, sluice gates, and compartmented fields have enabled the farms of the Red River Delta to produce 18% of Vietnam's rice (Oryza sativa) crop (figure 1), 26% of the country's vegetable crops, and 20% of capture and farmed aquaculture (Redfern et al. 2012). Agriculture in this fertile delta was transformed in the 11th and 13th century AD by large-scale hydraulic projects to protect the delta from flooding and saltwater intrusion, and provide field drainage during the wet season and crop irrigation in the dry season (Tinh 1999). The 20th century brought advancements in agricultural science globally—new crops and livestock genetics, inorganic fertilizers, mechanization, and pesticides that could double and triple food production per unit of land. It was the diesel pump combined with post-Vietnam War agricultural collectivization from 1975 to 1988 that brought the Green Revolution to the Red River Delta.
