This aerial picture taken on July 24, 2020 shows fishermen checking their fishing traps at the estuary of Dead River (Lumi i Vdekur) in the village of Adriatik near the Divjaka Lagoon. - The blue crab's colourful claws are pretty but dangerous: ripping up fishing nets and upsetting ecosystems off Albania's coast, the invasive species is a source of daily anguish for Balkan fishermen struggling to make ends meet. Native to the Atlantic, the crustacean started emerging in Albania's Adriatic waters over a decade ago, aided by warming sea temperatures. (Photo by Gent SHKULLAKU / AFP)
