Spanish fisherman Santi Diaz Mosquera knows every journey down the treacherous Galician rocks in search of a handful of prized gooseneck barnacles could be his last. The dangerous practice of darting in between the huge waves that hammer against the Ferrol coastline in northwest Spain to cut the rare delicacy from the rocks claimed the life of his father nearly 15 years ago. But for Mosquera, the rewards from a successful mission are too great to ignore. He can sell 1 kg (2 lb) of the crustaceans for around 70 euros ($73). That rises to 250 euros ($260) at auction in the week before Christmas, a big sum in a region struggling since the collapse of its shipbuilding industry. On a good day Mosquera can catch 10 kg of gooseneck barnacles, also known as percebes. REUTERS/Nacho Doce SEARCH "BARNACLES" FOR THIS STORY. SEARCH "WIDER IMAGE" FOR ALL STORIES.

A shrimp is seen after being rescued by volunteers from the waters of the Rio Doce (Doce River) in Linhares, where, according to Brazil's environmental regulator IBAMA, is about to be flooded with mud after a dam, owned by Vale SA and BHP Billiton Ltd burst, Brazil, November 19, 2015. The collapse of two dams at a Brazilian mine has cut off drinking water for quarter of a million people and saturated waterways downstream with dense orange sediment that could wreck the ecosystem for years to come. Nine people were killed, 19 are still listed as missing and 500 people were displaced from their homes when the dams burst at an iron ore mine in southeastern Brazil on Nov. 5. Scientists say the sediment, which may contain chemicals used by the mine to reduce iron ore impurities, could alter the course of streams as they harden, reduce oxygen levels in the water and diminish the fertility of riverbanks and farmland where floodwater passed. According to the predictions of Brazil's environmental regulator IBAMA, the mud will touch the sea, in Espirito Santo state coast, on this Friday. REUTERS/Ricardo Moraes

Josue Vega nets crabs one-by-one with his family at a parking lot abutting Long Wharf Park in Cambridge, Maryland August 26, 2015. Young people in the small rural shore towns of Chesapeake Bay, which straddles the eastern U.S. states of Maryland and Virginia, are shunning the erratic pay of "watermen", who catch crabs using skills such as baiting a crab pot or handling a trotline, previously passed down through the generations. Seasonal workers from Mexico fill many of the manual jobs in picking houses to process the crustaceans. The industry faces other headwinds, environmental issues and an increasingly global agricultural market among them. Last year's harvest was the lowest recorded in 25 years after the crab population crashed in the 1990s and early 2000s.
