Measuring the nutritional benefits of fisheries adaptations in the Pacific Islands region

Fish are an important source of dietary protein 1 and essential nutrients 2 . However, efforts to sustain these benefits across the global south are increasingly challenged by population growth, habitat degradation and climate change 3 , 4 , 5 . These pressures are particularly acute in several Pacific Small Island Developing States (SIDS), where gaps have emerged between the recommended level of fish consumption needed for good nutrition and the supply of fish from coral reefs and other coastal habitats 6 , 7 , 8 ̶ the source of most fish consumed in the region 8 , 9 , 10 . Adaptations are needed to sustain recommended levels of fish consumption. Importantly, a practical metric is also needed to measure the success of these adaptations in delivering the intended nutritional benefits.
