It’s been almost six years since the New Fulton Fish Market moved to The Bronx on Nov. 14, 2005 after 180 years of smelling up lower Manhattan. The $86-million, half-mile long facility houses more than 30 wholesale distributors, bringing over a billion dollars in annual revenue. Critics contend it lacks the character of the old market by the Brooklyn Bridge, and its remote location contributes to a recent slump in sales. Others say the city-owned Hunts Point warehouse has modern amenities that keep the produce fresh and in high demand. Most recently, one operator declared bankruptcy leaving the warehouse 15 percent empty. But on a midnight visit not too long ago, the market still pulsates with energy. And with the thick smell of the sea wafting over the vending spots, there’s no mistaking this is the world’s second largest fish market.
