The need to uncover, interrogate, and integrate women’s contributions to fisheries in research and development has never been clearer. As coastal and fisheries management continues to look to the Sustainable Development Goals and the Voluntary Guidelines for Securing Sustainable Small-Scale Fisheries in the context of Food Security and Poverty Eradication, as frameworks and mandates, gender equity and equality have become a central concern.

Women play an important role within small-scale fishing communities in sub-Saharan Africa through engaging in fish value chain activities and contributing to household food security and income. There is, however, little empirical information about the nature of women’s engagement in small-scale fishery value chains and the outcomes of that engagement especially in Malawi, our study country.

Failure to address unsustainable global change is often attributed to failures in conventional environmental governance. Polycentric environmental governance—the popular alternative—involves many centres of authority interacting coherently for a common governance goal. Yet, longitudinal analysis reveals many polycentric systems are struggling to cope with the growing impacts, pace, and scope of social and environmental change. Analytic shortcomings are also beginning to appear, particularly in the treatment of power.

Improving livelihoods and livelihood opportunities is a popular thrust of development investments. Gender and other forms of social differentiation influence individual agency to access, participate in, and benefit from existing, new, or improved livelihood opportunities. Recent research illustrates that many initiatives intended to improve livelihoods still proceed as “gender blind,” failing to account for the norms and relations that will influence how women and men experience opportunities and outcomes.

Micronutrient deficiencies account for an estimated one million premature deaths annually, and for some nations can reduce gross domestic product by up to 11%, highlighting the need for food policies that focus on improving nutrition rather than simply increasing the volume of food produced3. People gain nutrients from a varied diet, although fish—which are a rich source of bioavailable micronutrients that are essential to human health—are often overlooked.

A fish agri-food system is an interconnected and interdependent system involving components of fish production through to processing, marketing and consumption. The CGIAR Research Program on Fish Agri-Food Systems (FISH) is a collaborative global partnership that aims to enhance the sustainability, productivity and resilience of fish agri-food systems, contributing to global goals for poverty reductions, food and nutrition security, and improved resilience of natural resource systems.

In 2018, WorldFish made notable progress toward our ambition to position fish firmly at the heart of discourse, policy and practice currently shaping the global thinking on transforming food systems, paying closer attention to nutrition and healthier diets and informing the path toward an inclusive and sustainable blue economy. Our achievements in 2018 are highlighted in this annual report.

Oomycete infections caused by Saprolegnia species represent an escalating problem in sustainable aquaculture development. This could be attributed to the ban of Malachite green and other carcinogenic agents aims at killing the pathogen. The increase in the incidence of saprolegniosis could also be attributed to its ability to form biofilms. In this study, the authors have investigated the effects of propionic acid (PPA) on reducing the viability of induced Saprolegnia biofilms using colorimetric MTS assay based on the reduction of tetrazolium salts.
