Historical Exploitation and Current Status

Atlantic Sturgeon populations in the United States have faced a long history of decline, primarily due to commercial exploitation. In the past, New York coastal gill-net fisheries specifically targeted adult Atlantic Sturgeon for their caviar and flesh, resulting in a significant decrease in landings.

This relentless extraction led to the collapse of the fishery in the late 19th century. However, the mid-1970s saw a resurgence of the fishery, mainly concentrated in the New York Bight (NYB) region, threatening the already vulnerable population once again.

Recognizing the urgent need for action, the fishery was closed in 1996, and Atlantic Sturgeon were subsequently listed as an endangered species. This status reflects the critical state of their populations and underscores the importance of conservation efforts to protect this iconic species.

To truly safeguard Atlantic Sturgeon from further decline, it is vital to address the consequences of commercial exploitation and implement measures to promote their recovery and long-term survival.

Commercial Exploitation and Population Declines

“The Atlantic Sturgeon has suffered greatly at the hands of commercial exploitation, enduring a century of population declines.
