A hint of optimism creeps into Darius Kasprzak's voice as he pilots his boat, the Marona, out of Kodiak harbor on a recent calm day.
"We're in the morning, we're at the start of the flood tide," he says. "This is where you want to be."
He is fishing a bay on the northwestern edge of the Gulf of Alaska, about 200 miles southwest of Anchorage. The chilly waters here are some of the most productive fish habitat on Earth. In a good year, Kasprzak could catch more than 100,000 pounds of cod.
