Hackleback

This is another contender when looking to substitute the classic Caspian sturgeon. Hackleback comes from the American Shovelnose sturgeon, a fish found in Mississippi River. Like the Sevruga both in the size and texture of its eggs, Hackleback has small firm eggs that are dark brown to black. Hackleback sturgeon has the smooth and delicate flavor of Caspian sturgeon, but milder and with a little extra nutty punch.
