Where do sturgeon live in the United States?

Why are sturgeon endangered species?

The shortnose sturgeon has been federally listed as endangered since the inception of the Endangered Species Act in 1973. Both shortnose and Atlantic sturgeon once thrived in the Delaware River, occurring in huge numbers that far exceeded those found in the Hudson.

When did the shortnose sturgeon become endangered?

The ESA was enacted in 1973 and all species that were listed as endangered in the 1969 Endangered Species Conservation Act were deemed endangered under the ESA. Shortnose sturgeon currently remain listed as endangered throughout their range along the U.S. East Coast.

Is there a recovery plan for the shortnose sturgeon?

NOAA Fisheries announces the availability of the final recovery plan for the shortnose sturgeon, as required by the Endangered Species Act of 1973 (ESA).

Do shortnose sturgeon live in saltwater or freshwater?

For the most part, shortnose sturgeon are amphidromous fish—meaning they are born in freshwater, then live in their birth (natal) river, make short feeding or migratory trips into salt water, and then return to freshwater to feed and escape predation. All sturgeon, including shortnose sturgeon, spawn in freshwater.

What are the most abundant fish in the Delaware River?

A New Jersey Fish and Wildlife boat drags a net, called a seine, in a “U” shape to collect fish in an annual Delaware River survey.

How many shortnose sturgeon are in Delaware River?

Although there are now about 12,000 adult shortnose sturgeon living within the Delaware River estuary, the population faces serious human-induced threats. Water quality contaminants such as endocrine distributing chemicals (EDCs) have been linked to reproductive and developmental disorders in many fish species.

How many Atlantic sturgeon in the Pee Dee River?

In the Pee Dee River, side scan sonar imaging was used to estimate a summer feeding aggregation, which may have included fish non-natal to the river, of approximately 1,823 to 1,944 adult or sub-adult Atlantic sturgeon in the river during the three day sampling period.

Why did the Atlantic sturgeon go extinct?

It was driven to near extinction by overfishing, by-catch in the shad fishery, damming of rivers, habitat destruction, and deterioration of water quality. Scientists and fishermen in the 19th and early 20th centuries did not distinguish between Atlantic and shortnose sturgeon, so there are no historical population estimates.

Are shortnose sturgeon no longer fished?

What are the barriers to shortnose sturgeon recovery?

Bycatch in commercial fisheries and increased industrial uses (e.g., hydropower, nuclear power, treated sewage disposal) of the nation’s large coastal rivers during the 20th century became the primary barriers to shortnose sturgeon recovery.

What are the shortnose sturgeon management units?

Shortnose sturgeon populations are divided into 19 management units based on presumed reproductive isolation [1]. Recent genetic analysis generally supports the management units, but suggests that the Delaware River be combined with Chesapeake Bay and the Ogeechee River be combined with the Altamaha River [2].

When did the Sturgeon become endangered?

Clearly, however, by the early 20th century populations were declining and by the 1950s or earlier had become endangered. The sturgeon was placed on the endangered species list of 1967. Shortnose sturgeon populations are divided into 19 management units based on presumed reproductive isolation [1].
