application of a sustainable fisheries development indicator system for taiwan s Aquaculture industry
Aquaculture, 2015Co-Authors: Kuo-huan Ting, Kun-lung Lin, Hao-tang Jhan, Teng-jeng Huang, Chi-ming Wang, Wen-hong LiuAbstract:Abstract The benefits of Aquaculture for humans worldwide have become increasingly important, especially in Asia. Although Taiwan does not have a high Aquaculture output, the superior Aquaculture techniques employed allow Taiwan to maintain competitiveness in the Asian region. The objective of this study was to evaluate the trend of sustainable Aquaculture fishery development in Taiwan, and the potential problems that exist. This study used a sustainable development indicator framework with 4 dimensions to analyze the sustainable development of Taiwan's Aquaculture fisheries. The results showed that between 2004 and 2009, economic indicators declined, posing substantial concerns for the sustainable management of Taiwan's Aquaculture. The results for the ecological, social, and institutional dimensions demonstrated stability or slight increases. Although the indicators partially reflect the effects of government Aquaculture policies, problems such as illegal Aquaculture fish ponds, inaccurate sales data, and sales channels controlled by a limited number of fishmongers and middlemen remain. In summation, current Aquaculture fisheries cannot achieve sustainability through production alone; instead, integrating the Aquaculture fisheries with social humanities, environment and ecology, and resource management is required.

Simulating the spillover benefits from R&D by a small producer country embedded in a co-authorship network: Aquaculture R&D in Germany
2012Co-Authors: Stefan Guettler, Linda Seidel-lass, Rolf A.e. MuellerAbstract:Aquaculture is increasingly important for the future supply of fish because of steadily increasing demand while supply from fisheries is stagnating. Despite the small size of their Aquaculture industries some German states have initiated sizeable Aquaculture R&D-programs to foster local Aquaculture industries. Three scenarios are computed with IFPRI´s DREAM-model to estimate the economic effects of Aquaculture R&D conducted in Germany. We correlate the size of R&D-spillovers across EU-15-countries to the strength of fishery and Aquaculture research cooperation that have been measured in a bibliometric study. The results of this paper provide important implications for political decisions concerning the allocation of public funds for R&D-projects in Aquaculture.

water metagenomic analysis reveals low bacterial diversity and the presence of antimicrobial residues and resistance genes in a river containing wastewater from backyard Aquacultures in the mekong delta vietnam
Environmental Pollution, 2017Co-Authors: Tatsuya Nakayama, Tran Thi Tuyet Hoa, Kazuo Harada, Minae Warisaya, Megumi Asayama, Atsushi Hinenoya, Joon Won Lee, Tran Minh Phu, Shuhei UedaAbstract:The environmental pathways for the dissemination of antibiotic resistance have recently received increased attention. Aquatic environments act as reservoirs or sources of antimicrobial-resistant bacteria, antimicrobial residues, and antimicrobial resistance genes (ARGs). Therefore, it is imperative to identify the role of polluted water in the dissemination of antimicrobial resistance. The aim of this study was to evaluate the antimicrobial residues, ARGs, and microbiota in the freshwater systems of the Mekong Delta. We selected 12 freshwater sites from Aquacultures and rivers in Can Tho, Vietnam and analyzed them for 45 antimicrobial residues and 8 ARGs by LC/MS/MS and real-time PCR, respectively. A 16S rDNA-based metagenomic analysis was conducted to characterize the water microbiota. Residues of sulfamethoxazole (10/12) and sulfadimidine (7/12) were widely detected, together with the sulfa-resistance genes sul1 (11/12) and sul2 (9/12). Additionally, sulfamethoxazole residues and the β-lactamase-resistance gene blaCTX-M-1 were detected in eight freshwater systems (8/12), suggesting that these freshwater systems may have been polluted by human activity. The metagenomic analysis showed that all the tested freshwater systems contained the phyla Proteobacteria, Actinobacteria, and Bacteroidetes, representing 64% of the total microbiota. Moreover, the Cai Rang River site (Ri-E), which is located at the merge point of wastewaters from backyard-based Aquacultures, contained the genera Polynucleobacter, Variovorax, and Limnohabitans, representing more than 78.4% of the total microbiota. Bacterial diversity analysis showed that the Ri-E exhibited the lowest diversity compared with other regions. Principal coordinate analysis showed that the differences among water microbiotas in backyard-based Aquacultures could be explained by the farmers' Aquaculture techniques. In conclusion, this study demonstrated a collapse of bacterial diversity at the merge point of wastewaters from backyard-based Aquacultures in the Mekong Delta.

The contribution of small-scale, privately owned tropical Aquaculture to food security and dietary diversity in Bolivia
Food Security, 2020Co-Authors: Sean Irwin, Mark S. Flaherty, Joachim CarolsfeldAbstract:New Aquaculture systems are emerging in new contexts around the world in part due to Aquaculture’s perceived development benefits. However, linkages between Aquaculture and food security in these systems are unclear. This study investigated the impact of emerging small-scale, business-oriented fish culture in central Bolivia on the food security and dietary diversity of Aquaculture producers ( n = 40) and workers ( n = 26) in the value chain and compared them to local non-Aquaculture farmers ( n = 40). Three pathways were investigated: fish consumption, household income, and women’s participation. Food insecurity was widespread and did not vary in a statistically significant way between groups, but a trend toward greater food security amongst Aquaculture producers was observed. Dietary diversity was highly homogenous, with the notable exception of high fish consumption amongst producers. Aquaculture was related to higher income, and income has a modest positive effect on food security for aquaculturists and non-Aquaculture farmers, but not Aquaculture value chain workers. Income did not have an effect on dietary diversity. Women’s involvement in Aquaculture was correlated positively to productivity, profitability, and size of operation, while male-only Aquaculture was negatively correlated to these. The value chain generated employment, especially for women, but average wages were higher for men. The research provides important insight into Aquaculture-food security linkages by showing that the introduction of small-scale business-oriented Aquaculture systems can provide nutritious products for regional consumption and can have positive effects on food security but is not sufficient to change local dietary preferences more broadly.
