The grandsons of Ernest Hemingway have received a hero's welcome in the Cuban village where the Nobel laureate spent decades hunting marlin, tuna and sharks in the waters of the Florida Straits.

John and Patrick Hemingway and a team of U.S. researchers started a five-day mission Monday aimed at building trust between U.S. and Cuban scientists. They hope to gain access to potentially invaluable knowledge about the massive game fish.

U.S. scientists believe Hemingway's fishing logs could contain the earliest detailed data on deep-ocean fish populations in the straits and hope to negotiate access to them from Cuban conservators.

Hemingway, whose Pulitzer-winning "Old Man and the Sea" relates an aging fisherman's battle with a giant marlin, was one of the earliest and most prolific sport fishermen in the straits.
