Sturgeons are seen in an aquarium in the Danube river port city of Tulcea, Romania on May 17, 2011. The sturgeon thrived in the Danube for 200 million years, migrating from feeding grounds in the Black Sea to Germany some 1,200 miles (2,000 kms) upstream. Archaeologists have found wooden sturgeon traps in the ruins of Roman fortresses behind the willow trees on the Danube's banks, along with bones dated to the 3rd century. Fishermen, unrestrained after the collapse of order in eastern Europe in 1989, caught them in huge numbers as they began their migration, trapping them before they could reproduce. Now, environmentalists are trying to head off the latest threat: a European Union plan to deepen shipping channels that they fear could eliminate the last shallows where the sturgeon deposit their eggs _ dooming the fish to vanish in its last stronghold in Europe. less
