In this photo taken March 28, 2017, Ken Massee, right, and Cort Jensen, left, biologists with the National Oceanic and Atmospheric Administration, collect eggs from a sablefish at a research facility in Manchester, Wash. The silvery-black fish prized for their buttery flavor live deep in the ocean, so researchers keep their labs cold and dark to simulate ideal conditions for sablefish larvae. Scientists are studying sablefish genetics and investigating ways to make it easier and more efficient to commercially grow and farm the fish. (AP Photo/Ted S. Warren)
