Plenty more fish in the sea? - is there a place for seafood within a healthier and more sustainable diet?

Abstract

Fish and other seafood species play an important nutritional, economic and social role within current diets worldwide, providing significant amounts of protein and micronutrients for an estimated 3 billion people. Advice to consume fish is a common feature of dietary guidelines globally, including in the UK. However, increased global demand for seafood has led to overfishing and environmental damage linked to aquaculture expansion; issues, which are exacerbated by climate change. This raises the question of whether future demand for seafood can be met sustainably. In this article, we provide professionals working in diet, nutrition and health with an insight into the challenges facing the seafood sector and offer advice on how consumers may include seafood within a healthier and more sustainable diet. While a complex and multi-faceted challenge, fisheries scientists estimate that successful implementation of better management practices (for farmed and wild-capture fisheries) can meet future demand, allow fish stocks to rebuild to sustainable levels, help mitigate environmental effects of aquaculture, and ensure profitable fisheries to support the ~60 million people employed by the seafood sector globally. Those working within the UK food system, including nutrition and health professionals, and businesses, can support the transition towards a more sustainable future for seafood by: encouraging consumption of a wider variety of species by UK consumers; increasing awareness of and knowledge about 'ecolabel' certifications designed to help consumers identify more sustainable choices; and engaging with multi-stakeholder initiatives addressing sustainability challenges facing the seafood sector.
