Smallholder aquaculture diversifies livelihoods and diets thus improving food security status: evidence from northern Zambia - Agriculture & Food Security
The study was conducted in Luwingu District in the Northern Province of Zambia in September 2017 (see Fig. 1). Luwingu has a total population of approximately 80,000 people as of the last census conducted in 2014 [35]. Over 80% of households are classified as rural agricultural households [36]. Most households engage in some form of farming, typically growing a combination of maize, cassava, beans, and groundnuts [37].
Proteomic analysis of Malaysian Horseshoe crab (Tachypleus gigas) hemocytes gives insights into its innate immunity host defence system and other biological processes
4.3 Implication of bacterial infection mimics LPS challenge on the abundance/expression of proteins in the HSC hemocytes The LPS was introduced to the isolated T. gigas hemocytes to mimic a scenario of bacterial infection and stimulate the innate immune response of the T. gigas through its hemocytes. Expectedly, antimicrobial proteins, CRP and hemocyanin were found to be degraded or reduced in expression following the LPS challenge (Fig 4).
Blue food demand across geographic and temporal scales - Nature Communications
Abstract Numerous studies have focused on the need to expand production of ‘blue foods’, defined as aquatic foods captured or cultivated in marine and freshwater systems, to meet rising population- and income-driven demand. Here we analyze the roles of economic, demographic, and geographic factors and preferences in shaping blue food demand, using secondary data from FAO and The World Bank, parameters from published models, and case studies at national to sub-national scales.
A major quantitative trait locus affecting resistance to Tilapia lake virus in farmed Nile tilapia (Oreochromis niloticus) - Heredity
Abstract Enhancing host resistance to infectious disease has received increasing attention in recent years as a major goal of farm animal breeding programs. Combining field data with genomic tools can provide opportunities to understand the genetic architecture of disease resistance, leading to new opportunities for disease control.
Dried small fish provide nutrient densities important for the first 1000 days
Abstract Inadequate nutrient intakes are prevalent among many populations in sub‐Saharan Africa and increasing fish consumption among pregnant/lactating women and children is one strategy to improve diets and address nutrient deficiencies. We report the nutrient content of two fish‐based recipes—fish powder and fish chutney—that contain dried small fish available in local markets in Zambia.
Malaria is a cause of iron deficiency in African children
Abstract Malaria and iron deficiency (ID) are common and interrelated public health problems in African children. Observational data suggest that interrupting malaria transmission reduces the prevalence of ID1. To test the hypothesis that malaria might cause ID, we used sickle cell trait (HbAS, rs334), a genetic variant that confers specific protection against malaria2, as an instrumental variable in Mendelian randomization analyses.
Blind spots in visions of a “blue economy” could undermine the ocean's contribution to eliminating hunger and malnutrition
Summary Increasing the production of food from the ocean is seen as a pathway toward more sustainable and healthier human diets.
Scenarios for Global Aquaculture and Its Role in Human Nutrition
1. Introduction Achieving global food and nutrition security goals within environmental boundaries will require transformation of global food production and distribution systems. This dual challenge will become ever more critical to solve with a global population headed to 10 billion by 2050, shifting socio-economic demographics, and with dietary trends toward more resource-intensive foods (Tilman and Clark 2014; Springmann et al. 2018; Willett et al. 2019).
Circadian rhythms in insecticide susceptibility, metabolic enzyme activity, and gene expression in Cimex lectularius (Hemiptera: Cimicidae)

Veera Singham Published: June 17, 2019 https://doi.org/10.1371/journal.pone.0218343 Figures Abstract Many insect species display daily variation of sensitivity to insecticides when they are exposed to the same concentration at different times during the day.
Club soars to victory
They took home RM500, a Nestle hamper and goodies sponsored by Great Eastern and RSH sports equipment. Team captain Izzahar Ramli, 24, said the victory here was their second, having emerged triumphant at the Penang Open Dodgeball Tournament last month. “The prize money certainly comes in handy as we can now use it to fund our competition at the National Dodgeball Tournament next week. “The victory was sweet and a boost to our confidence.
