Vitamin deficiencies are known to be common among infants residing in low- and middle-income countries but relatively few studies have assessed several biochemical parameters simultaneously.The purpose of this study was to describe the status of key vitamins (A, D, E, B6, B12 and folate, and the biomarkers total homocysteine and methylmalonic acid) in a random sample of breastfed infants, from two months of age, residing in Bhaktapur, Nepal.
There is increasing awareness that integrating gender into development frameworks is critical for effective implementation of development strategies. In working to alleviate rural poverty, the CGIAR Research Program on Aquatic Agricultural Systems (AAS) recognizes that “business as usual” gender integration approaches will not deliver lasting and widespread improvements in agricultural productivity, poverty reduction and food security. In response, AAS operationalized a gender transformative approach.
Where access to renewable natural resources essential to rural livelihoods is highly contested, improving cooperation in resource management is an important element in strategies for peacebuilding and conflict prevention. While researchers have made advances in assessing the role of environmental resources as a causal factor in civil conflict, analysis of the positive potential of collective natural resource management efforts to reduce broader conflict is less developed.
In this review, the author provides an overview of the small water bodies as an important inland fishery resource and analyses the global trends in their utilization. He also assesses the opportunities for enhancing fish production from these water bodies based on the strengths and weaknesses of the different management options.
Seasonal floodplains under private and public ownership in the Indo-Ganges river basin provide food and income for millions of people in Bangladesh. This research aimed to understand the complex institutional relations that govern ownership, access, and control of the floodplains under Community Based Fish Culture (CBFC) to increase fish production and overall livelihoods of the poor.
Biophysical impacts of aquaculture, with consequences for biodiversity, vary with species and culture systems and include issues such as: nutrient enrichment/removal, chemicals, land use, species introductions, genetic flow to wild populations, disturbance of balance or introduction of pathogen/parasites, consumption of capture fishery resources, energy, and greenhouse gas emissions. Guiding principles, labeling schemes and various tools are needed to analyze performance and conformance.
The role of the WorldFish Center is to research and disseminate appropriate aquaculture and fisheries technologies for sustainable agricultural intensification. To achieve these goals the WorldFish Center works in partnership with the government of Malawi. It leverages success by collaborating with both local and overseas academic research organizations, drawing funding from the global development community.
Development programmes aimed at raising income levels of the half-million Philippine traditional municipal fishermen have emphasized production-oriented projects designed to up-grade vessels and gear. Review of recent biological, technical, and socio-economic research provides evidence that technology-based efforts have generally not been successful, and that the coastal resources fished by municipal fishermen are not as extensive as previously supposed.
Despite the success in fertilization and hatching of fish eggs with cryopreserved sperm, report on growth and survival of larvae produced from frozen-thawed sperm is inadequate. This study evaluates the applicability of cryopreserved sperm for mass seed production by comparing the growth and survival of a popular food-fish olive barb, Puntius sarana (Hamilton 1822) larvae produced from cryopreserved and fresh sperm.
In the present paper, the phylogeographies of two monogenean species, Pseudokuhnia minor and Kuhnia scombri, on the same species of host, Scomber japonicus, were studied.
