The impressive growth in aquaculture is now commonly dubbed a “blue revolution.” In some Asian countries, fish availability has increased at a faster rate in recent decades than did cereal availability during the Green Revolution. As an example, Bangladesh is one country where aquaculture has increased almost eightfold since the early 1990s. This growth has important implications for food and nutrition securities. Yet, there is little research on the determinants and impacts of this growth to document the lessons, identify evolving issues, and guide policy discussions.

The global demand for fish and fish products is continuously increasing. However, fisheries management is still insufficient, leading to over-exploitation, illegal fishing and massive post-harvest losses. Our authors describe what has to be done.

It would be difficult to imagine the diet of the local consumers around Lake Victoria without the silver cyprinid. The small fresh water sardine also plays an important role in women’s participation in Kenya’s fishery sector. However, in spite of intensive efforts, there is still a long way to go before they have achieved an equal role in the value chain.

Aquaculture holds a big potential to satisfy the growing demand for aquatic food. Setting out from lessons learnt in past development projects, our author describes what fish farming systems must look like to fit the needs of smallholders and the environment.

Mauritania’s coastal waters are among the world’s richest fishing grounds. However, just as in many other countries around the globe, the sustainable use of this resource is under threat from illegal fishing and overfishing. KfW contributes to protecting the valuable fishing grounds with the aid of modern surveillance systems and rigorous conservation and species protection measures.

A project run by the WWF has set itself the goal of transforming Philippine tuna fisheries towards more sustainable practices, securing the livelihoods of the small-scale fishers in the long term. European buyers who have committed to source from them provide the necessary incentives.

During the last few years, the donor community has increased its efforts to reduce the large amounts of fish lost in the distribution chain in artisanal fishery, an endeavour that ought to be welcomed in principle. However, focusing on one single solution, the development of an expensive cool chain and the supply of fresh or frozen fish, represents a massive interference with the traditional processing and distribution channels, with women being the main losers. Our author calls for more foresight in international co-operation.

The multitude of certification schemes in seafood production has assumed massive dimensions, posing considerable challenges for all actors in the supply chain. Here, the Global Sustainable Seafood Initiative seeks to provide a remedy.

Experts agree that the rising demand for fish for human consumption cannot be met without a major expansion and sustainable intensification of aquaculture. Our WorldFish authors describe the areas in which research plays a particularly important role in this context.

Often with just one or two ponds managed by a single person or family, smallholders make up an important share of the world’s seafood production. So why are by far the minority of certified aquaculture operations smallholders?
