Where the Jellyfish Roam

Following the path of seafood from ‘fisherman to fork’ is important for regulating the industry and reassuring consumers – but current analytical methods are limited when it comes to proving claims about origin. Luckily, jellyfish are joining the frontline in the fight against food fraud. Scientists from the University of Southampton recently used the “chemical record” collected from jellyfish to create a stable isotope-based map of the seas (1).
