Walter de la Cruz scrambled down a large sand dune in the fog to reach a rock overlooking the Pacific Ocean, where he has fished for three decades. He cast a hook into the waters off Peru’s coast several times, with no luck. One attempt yielded a piece of plastic stained with oil.
De la Cruz, 60, is one of more than 2,500 fishermen whose livelihoods have been cast into doubt as a result of a large crude-oil spill at the Spanish-owned Repsol oil refinery on Jan. 15.
