The Atlantic Sturgeon

Oct 3, 2017

In the late nineteenth and early twentieth centuries Atlantic sturgeon were a highly sought after target for commercial caviar fishermen on the Atlantic coast. Overfishing and pollution were initial reasons identified for population declines. Successful fall spawning has occurred for 3 consecutive years in 2011, 2012 and 2013 at the Bears Bluff National Fish Hatchery, SC. A successful temperature regime for fall spawning (without the use of hormones) has been developed for natural tank spawning. Current effort is focused on refining spawning, hatching and rearing techniques.
