Urban aquaculture for resilient food systems
No full textFirst paragraph: Urban aquaculture has been defined in several ways. Clearly the location of aquacultural production within built-up areas of cities or within municipal administrative boundaries can be classified as such but the definition 'urban' has been attached to aquaculture outside this strictly literal definition (Little et al. 2012). Aquacultural practices established in conjunction with commercial, industrial and infrastructural developments - for example, power stations and dams for hydroelectric power generation - have previously been categorized as urban (Bunting and Little 2003, 2005; Leschen et al. 2005; Bunting et al. 2006). Aquaculture located on the edge of towns and cities (peri-urban) that makes use of nutrientenriched drainage and sewerage water for producing food and at the same time treats the waste is often termed urban (Edwards 2003). The city as a source of nutrients and other key inputs, as well as being the major demand driver for the outputs, explains the location of much traditional or emergent aquaculture being located close to urban settlements. The very nature of'urban' in densely populated, dynamic economies that are increasingly well networked is subject to redefinition (Leschen et al. 2005; Little and Bunting 2005). Aquacultural practices developed in rural areas but inspired by examples operated in urban areas or based on knowledge derived from urban-rural migrants and returning students or intended to supply demand from urban markets may be regarded as urban from a sociocultural or social-psychological perspective (Iaquinta and Drescher 2000; Bunting and Little 2005)
Aquaculture Technologies for Food Security
No full textAquaculture has been identified as a critical part of supporting food security, especially for low- and medium-income countries (LMIC) in which fish is an established and key part of diets. Finfish and other aquatic products (“fish”) are high in protein and rich in micronutrients. Employment for low-income people throughout aquaculture value chains is increasingly contributing both directly and indirectly to their food and nutritional security

Evaluating the potential of innovations across aquaculture product value chains for poverty alleviation in Bangladesh and India
No full textEvidence is presented that innovation across aquaculture value chains can contribute to poverty reduction through income generation and increased consumption of nutritious aquatic foods. Innovation is defined and contextualized in relation to aquaculture development. Opportunities for aquaculture innovation across value chains for poverty reduction and sustainable production are described. Contemporary trends in aquaculture development in Bangladesh and India, with a focus on 2011-2020, are reviewed, as understanding transformative change to aquatic food systems during this period could benefit millions of poor and marginal consumers. Market-led commercial production, instigated by private sector entrepreneurs for domestic markets, has underpinned the surge in freshwater fish culture in key geographical locations. In contrast booms in shrimp production have been associated with export opportunities and related cycles of boom-and-bust have been described, with busts attributed to falling market prices and disease outbreaks. Innovation could safeguard supplies of affordable fish to poorer groups (especially young children and pregnant and breastfeeding women) and enable better health management of aquatic animals including coordination of surveillance and disease control measures. Innovation to effectively promote better management practices and integrated services provision to large numbers of small- and medium-scale producers could contribute to poverty reduction. Opportunities for future innovation to ensure that aquaculture development is sustainable are critically reviewed. Innovative strategies to add value to byproducts and utilize waste resources could avoid negative environmental impacts, recycle nutrients and create income generating opportunities. A new paradigm for development assistance that identifies and supports promising innovation trajectories across jurisdictions, product value chains, institutional regimes and food systems is needed. Government agencies must be responsive to the needs of businesses throughout aquatic food systems and devise policies and regulatory regimes that support transformative and sustained growth of the aquaculture sector. Investment in capacity-building, education, research and training and action to promote an enabling institutional environment must be regarded as essential elements to maximize and share equitably the benefits arising and avoid potential negative impacts of inappropriate innovations

“‘With God For Us, We Must Be Successful’: Nationalism, Slavery, and Death in the Civil War Letters of Robert Franklin Bunting”
No full textRobert Franklin Bunting (b. 1828, d. 1891) was a preeminent Presbyterian minister, church planter, and Confederate chaplain. Before serving as a chaplain, he planted multiple churches in Central Texas. As a chaplain, he wrote numerous letters to various Texas newspapers. This thesis utilizes Bunting’s letters to understand how white southerners understood and interacted with the primary social issues in the Civil War. Specifically, it examines how Bunting understood nationalism, slavery, and death. His perception of these issues flowed from his religious worldview. As such, it highlights his religious interplay with these issues and contributes to furthering our understanding of religion\u27s role in developing the cultural contours of the war
Mixed-sex Nile tilapia (Oreochromis niloticus) can perform competitively with mono-sex stocks in cage production
No full textAll-male tilapia stocks are widely used by farmers to supply both domestic and international markets with homogenous, large sized fish (500 g+). While a number of strategies are possible, hormonal treatment of fry with 17α-methyltestosterone (MT) is the most common method used by commercial farmers due to its low cost and ease of application. However, contrasting to its current widespread use the implications of MT in tilapia farming have raised concerns especially from public and environmental perspectives. Therefore, in this study we tested the impact of stocking a mixed-sex fast growing strain of Nile tilapia (Oreochromis niloticus) fry at high density and then grading out females at 4 or 8 weeks intervals during grow-out and compared final production with a standard MT-treated mono-sex system. From a production perspective, the strategies to remove females at 4 or 8 weeks were successful as no differences in harvest weight, survival and feed conversion rate were observed when compared to the MT-treated group. Similarly, no differences at harvest were obtained in terms of external appearance, Fulton's condition factor, gonadosomatic index, fillet yield, fat-somatic index and visceral-somatic index (%) between MT-monosex group and the groups where females were removed (4 or 8 weeks). However, a financial analysis of this approach showed that the additional costs (fry, feed and labour) involved in the mixed-sex strategy resulted in lower profits. This could be mitigated if a proportion of the removed females could be sold at a premium price as potential broodstock. In the model presented, sales of 13% of the removed females for broodfish at current Thai prices, or a premium of at least 8% for non-sex-reversed final product would be sufficient for the mixed-sex system to return a higher profit than the mono-sex system. The latter strategy could also enable further social licence through use of small fish in nutritional and outgrower initiatives
