Since 4,900 of these were stocked hatchery-raised fish, about 4,600 fish were thought to be of wild origin. Fourteen feet long, it weighed eight hundred pounds! The shortnose is protected as an endangered species, and must be released without harm whenever taken. Sturgeon are bottom feeders, using whisker-like barbels on the underside of their snouts to find food - chiefly worms, insects, crustaceans, and small fish - that is sucked up in their tube-like mouths. In New York, mature males immigrate into the Hudson River in early spring, and females follow approximately one month later. The biggest Atlantic sturgeon on record was caught in Canada. Fishing begins by placing three nets at slack tide, the time when the river moves the slowest. Benthic habitat maps developed for the Hudson River will be used to quantify and predict habitat use. Males return to spawn as early as age 12. The sturgeon, one of the Hudson River's most famous, enormous and delicious fish, may be coming back.
