NOAA’s Fisheries Service is proposing several measures to end overfishing and rebuild blacknose sharks and other shark populations.  Nine public hearings will be held on the proposal, from New England to the Gulf of Mexico, in August and September 2009 (Public Hearing Dates-Locations).
     
“Our latest stock assessment found that the blacknose shark is depleted and the rate of fishing is unsustainable,” said Jim Balsiger, acting NOAA assistant administrator for NOAA’s Fisheries Service. “Blacknose sharks are vulnerable because they bear few young (3-6 young per year at best).  The proposed measures will help rebuild the species, an important part of the ecosystem in the south Atlantic, Gulf of Mexico and the Caribbean Sea.”
     
An average blacknose shark grows to about 4 ½ feet (about 1.3 meters), and  is currently fished as a game fish by recreational anglers and are fished commercially for their meat, which is sold fresh or dried and salted.  These sharks play an important role in the ocean ecosystem, helping control various fish populations.
     
The stock assessment determined that reducing the annual mortality of blacknose sharks, the only small coastal shark that has been determined to be fished at an unsustainable rate and have a depleted population, by approximately 78 percent across all fisheries could result in rebuilding by 2027.  To rebuild the blacknose shark population NOAA proposes creating a separate blacknose shark quota.  Until now, landings of blacknose sharks have been counted against the small coastal shark complex quota.  The proposed annual quota would be 6,065 blacknose sharks, or 14.9 metric tons dressed weight (shark weight without head, guts and fins), a 78 percent decrease from the 1999-2005 fished average of 27,484 blacknose sharks, or 62 metric tons dressed weight.

The proposition also determines that only commercial fishermen with a directed permit would be allowed to land blacknose sharks until the quota is reached.  Commercial fishermen with an incidental shark permit and recreational fishermen would not be allowed to land blacknose sharks. 
     
To help rebuild the blacknose population, NOAA’s Fisheries Service is also proposing to prohibit the landing of all Atlantic sharks with gillnet gear — the primary way blacknose sharks are caught — from South Carolina south, including the Gulf of Mexico and the Caribbean Sea.  This gillnet fishery targets small coastal sharks, including blacknose.
     
While blacknose sharks are the only small coastal shark that needs management updates to be rebuilt, because they are frequently caught with other small coastal sharks, there is also a proposed annual quota for the non-blacknose small coastal sharks, including finetooth, Atlantic sharpnose, and bonnethead sharks, as well as smooth dogfish.  
     
NOAA’s Fisheries Service will also identify essential habit for smooth dogfish, a species that lives in coastal waters and ranges from Massachusetts to the Gulf of Mexico and Caribbean Sea.
     
In addition, the proposal promotes the live release of shortfin mako sharks by commercial and recreational fishermen to help rebuild the species population in the Atlantic Ocean.  The U.S. contributes less than 10 percent to the overall catch in the Atlantic.  NOAA’s Fisheries Service has proposed to take action at the international level to develop measures to end overfishing of the species.
