Abstract	Low-quality complementary foods combined with inappropriate feeding practices put children under the age of five in developing countries at high risk for undernutrition. This study explored dietary diversity, fish consumption patterns and nutritional status of children in Luapula, a rural province in Zambia, where households rely on capture fisheries for their livelihoods. In the cross-sectional study, households with children aged 6–59 months were enrolled in the study. A semi-structured questionnaire was utilised to collect socioeconomic characteristics, dietary intake and anthropometric data. Descriptive statistics and bivariate associations were conducted. 23% of children aged 6–23 months met the minimum dietary diversity. About 49% and 41% of the children were fed on fresh small pelagic fish and large dried fish once to twice a week, respectively. Imbilya (Serranochromis mellandi), Chisense (Poecilothrissa moeruensis), and amatuku (Tilapia sparrmanii) were the most preferred fish species due to their availability and affordability. Only 3.5% of children consumed porridge to which fish powder had been added. There was a significant difference in the height for age z scores of children in the two communities (χ2= 12.404; p = 0.002, d.f = 2). Low dietary diversity was observed across the fishing and non-fishing communities and less than half of the children consumed fish despite proximity of the study sites to one of the largest water bodies in Zambia. Better nutrition outcomes were observed among children in capture fisheries dependent households. Nutrition education in growth monitoring and promotion centres should address the issue of adequacy of diets with regard to frequency and diversity.

Abstract	Abstract Background Much has been made of the potential for aquaculture to improve rural livelihoods and food and nutrition security in Africa, though little evidence exists to back such claims. This study, conducted in northern Zambia, assessed the benefits of adopting aquaculture by comparing a sample of households with (n = 177) and without fishponds (n = 174). Results On-farm food production was assessed by summing all crop and livestock activities and calculating a production diversity score (PDS) of key food groups. Aquaculture households had greater crop diversification and were more associated with key nutritious foods grown on the farm, possibly due to additional water irrigation capabilities. A greater diversity of cultivated crops led to better household dietary diversity scores (HDDS). We further assessed the frequency of consumption of 53 food items (including 30 fish species) over a period of 4 weeks via a Food Frequency Questionnaire (FFQ). Using the Simpson’s Index, aquaculture households had greater diversity and evenness in the distribution of foods and fish species consumed, particularly for foods grown on the farm. Using livelihood and dietary factors in a multilevel probit regression on the Household Food Insecurity Access Scale (HFIAS), we found that adopting aquaculture gave households almost two times more likelihood of improving their food security status. Households could further improve their food security outcomes by growing and consuming certain vegetables, especially those that could be integrated along pond dykes. Conclusions The study suggests three clear pathways to food security. (1) Increasing wealth and income from the sale of fish and integrated vegetables and/or crops, which can be used to purchase a diversity of foods. (2) Increasing food and nutrition security via the direct consumption of fish and vegetables grown on the farm. (3) Improving irrigation capabilities in integrated aquaculture–agriculture systems that has direct impact on pathways 1 and 2. Aquaculture should ...

Abstract	Increased intake of animal-source foods (ASFs) is crucial to tackle multiple nutritional challenges in Bangladesh, and contribute to achieving targets under the Sustainable Development Goals (SDGs). Qualitative and quantitative data were collected to assess current ASFs intake behaviors and preferred ASFs, among three types of households, namely 1. aquaculture intervention (AI); 2. aquaculture non-intervention (ANI); and 3. non-aquaculture non-intervention (NANI) households and children aged 6−59 months, to understand whether intake of ASFs vary by the types of households. Purposive sampling was conducted to obtain a total of 100 households (AI, 50; ANI, 25; NANI, 25). Fish was the most commonly consumed (52.2−61.5%) and preferred (73.9−84.6%) ASF by the majority households, across study groups; although amount (mean ± SD) of intake (g/d/person) by NANI households was statistically significantly lower (NANI, 105.5 ± 53.3; p < 0.001), compared to other two groups (AI, 163.6 ± 64.7 and ANI, 159.6 ± 53). Fish species selection for household consumption was led by taste, health benefits, availability, and price. Pangasius was the first fish species of choice fed to children, due to having fewer small bones compared to other commonly consumed fish species. Dietary interventions to prioritize fish, in targeting increased intake of ASFs among study population, for improved food and nutrition security.

Abstract	BACKGROUND:This study examines socio-economic determinants of food consumption patterns amongst women of reproductive age and children aged 6-59 months from urban poor settlements of Lusaka and their implications for nutritional status. Particular emphasis was placed on the role of fish in their diets and nutritional status. METHODS:A cross-sectional survey design was applied, in which 714 mother-child dyads, with children aged 6-59 months were enrolled. A three-stage randomized cluster sampling approach was applied. RESULTS:The mean dietary diversity score among children aged 6-23 and 24-59 months was 2.98 (±1.27) and 3.478 (±1.07), respectively. In children aged 6-23 months, there was a significant difference in their nutritional status, based on fish consumption (χ2 = 10.979, df = 2, p = 0.004). Children from poorer households consumed mostly small fish (Kapenta). The quantity of fish consumed by children was significantly associated with stunting in both age groups, odds ratio = 0.947 (95% CI: 0.896, 1.000) for children aged 6-23 months and odds ratio = 1.038 (95% CI: 1.006, 1.072) for children aged 24-59 months old. Other significant risk factors for stunting in children aged 6-23 months were the child's age, mother's body mass index, access to treated water and child morbidity. Child's age, mother's educational level and wealth status were determinants of dietary diversity in children aged 6-59 months as shown by the Poisson regression. CONCLUSION:Nutritional status of children aged 6-23 months is associated with fish consumption, with children consuming fish less likely to be stunted. Small fish (Kapenta) is an animal-source food that is particularly important in the diet of children in urban poor households in Zambia and contributes to better nutritional outcomes. As all small fish stem from capture fisheries, sustainable one health environmental integration, monitoring and management strategies are desirable.

Abstract	Aquaculture in Zambia is growing and likely to play an important role for food and nutrition security in the country. While outputs in capture fisheries and small-scale aquaculture are stagnating, commercial aquaculture holds promising potential to help increase the availability and accessibility of fish in the country, especially for the poor. While fish supply per capita has increased over the last decade, little is known on the food consumption patterns and the role of farmed fish in the diets of resource-poor households. The aim of this paper is to (1) generate information on the fish consumption patterns of poor households in urban Zambia and (2) explore the role of Zambian aquaculture as a source of fish among poor urban households. Multi-stage stratified cluster sampling was used to sample poor households in Lusaka. Data on fish consumption were collected through a cross-sectional study that analyzed a quantitative household survey (N = 714). Using Principal Component Analysis (PCA), the sample of poor households was further disaggregated into four socio-economic strata (asset-based) to compare household fish consumption in respect to poverty levels. The results of the study show that the poorest households almost exclusively rely on small, dried fish products from capture fisheries while the slightly better off households among the poor strata tend to consume larger, fresh fish, such as tilapia, which are partly supplied by aquaculture producers. These results imply that the poorest of the poor households – unlike the better off households – are less likely to supplement their diets with fish products from aquaculture. This could have negative consequences for the food and nutrition security of disadvantaged consumers, given the stagnation of fish supply from Zambian capture fisheries and an increasing population that demands fish. For aquaculture to contribute more effectively to fish supply among poor consumers, we conclude that the sector would need to further expand its economies of scale (to decrease unit production costs), explore producing smaller-sized fish (to increase accessibility), promote the development of small and medium-sized fish farming, and diversify production with respect to species and products that better respond to the needs of poor consumers.

Abstract	Reorienting food systems towards improving nutrition outcomes is vital if the global goal of ending all forms of malnutrition is to be achieved. Crucial to transitioning to nutrition-sensitive agriculture is valuing and measuring nutritional quality of the outputs of agricultural production. We review existing indicators which capture an element of nutritional quality applicable to different stages of the food and nutrition system. Applying relevant indicators from the agricultural production stage to selected aquaculture systems, we compare and contrast their strengths and limitations. âNutritional yieldsâ, âpotential nutrient adequacyâ and âRao's quadratic entropyâ show particular promise in capturing the ability of a production system to nourish the most people and could be useful tools for prioritising investments and decision-making in the public, non-government and private sectors driving agriculture.

Abstract	Since 1961, global per capita fish consumption has nearly doubled. Much of the increase has been due to aquaculture. Bangladesh, the world's eighth largest fish producing country, has been part of this transformation. Despite having vitamin A supplementation and fortification programs, the prevalence of inadequate vitamin A intake (IVAI) in Bangladesh is very high, estimated to be 60%. The promotion of a small indigenous fish, high in vitamin A – mola carplet – offers a promising food-based approach to improving vitamin A status of the 98% of Bangladeshis who eat fish. The objective of this paper was to conduct a benefit–cost analysis of a national household pond Mola Promotion Program (MPP) in Bangladesh.Using the 2005 Bangladesh Household Income and Expenditure Survey (HIES) and nutrition and health statistics, we developed baseline estimates of usual vitamin A intake, the prevalence of IVAI and disability-adjusted life years (DALYs) attributable to vitamin A deficiency (VAD). Drawing on a WorldFish project and HIES data, we designed and modeled the implementation of a MPP, and calculated the additional vitamin A intake it would provide, calculated new incidence rates of VAD-related health outcomes and estimated MPP-attributable annual changes in DALYs. The MPP's total health benefits were calculated over the program's 11-year phase-in as the annual sum of DALYs saved. The MPP's costs were estimated as the sum of the costs of a small fish program of the Fisheries Development Program plus the costs of mola brood stock, other inputs and additional farmer training-related costs. Program costs and benefits were combined to produce estimates of the cost-effectiveness of the program.An 11-year, $23 million project would increase average daily vitamin A intakes by 7μg retinol activity equivalent (RAE), reduce the prevalence of IVAI by 1.1 percentage points, and save 3000 lives and 100,000 DALYs, at a cost of $194 per DALY saved. The MPP's impact would be concentrated among homestead pond-fishing households that would consume 60% of the additional mola produced. Among these, it would reduce IVAI prevalence by 7 percentage points. If the MPP was implemented for at least 20years, it would dominate – have higher health benefits and lower total costs – than a national vitamin A wheat flour fortification program.By World Bank and World Health Organization criteria, the MPP is a cost-effective approach to reduce the burden of micronutrient malnutrition in Bangladesh.

Abstract	Freshwater social-ecological systems are shaped by site-specific characteristics, environmental change and annual fluctuations, and the actions of resource users and managers. Our primary aim is to analyze the relative effects of these multifacted forces on fishery productivity and biodiversity using the case of community-managed protected areas within Cambodia's rice field fisheries, known as community fish refuges. Our secondary aim is to take advantage of fixed-effects regression models, a rigorous approach that is common in other disciplines, yet novel to analysis of social-ecological system productivity, and allows comparison of each site to itself across time using observational data. We analyze the relative associations of site characteristics, annual fluctuations, biophysical modifications (e.g., deepening, creation of inlet/outlets, etc.), and governance capacity (i.e., community committee meeting intensity, fundraising to support illegal fishing patrols, etc.) with fish biomass and biodiversity within 40 refuges over three years. We find that seasonal and site-specific effects within this system relate strongly to biomass and species richness patterns. We also find an association between biomass and biodiversity and some elements of governance capacity building. Our findings suggest that in this setting solutions tailored and responsive to the local context may be most appropriate given the strong interannual and site-specific drivers. Methodologically, the dynamism and site specificity of such systems befits within-site comparisons over long time horizons to appreciate the factors that drive biomass and biodiversity.
