Request for Information about Pacific Shark Tagging Activities

 

Dear All,

 

We are writing to you in connection with the Shark Research Plan currently being implemented by the Secretariat of the Pacific Community (SPC) on behalf of the Western and Central Pacific Fisheries Commission (WCPFC).  The Shark Research Plan is designed to gather all relevant fisheries and biological information about key shark species in the Western and Central Pacific Ocean and to support shark stock assessments and inform future discussion of management measures.  For more information about the Shark Research Plan please refer to http://www.wcpfc.int/node/2950 and http://www.wcpfc.int/doc/wcpfc7-2010-16/spc-progress-toward-shark-assessments.

 

One of our new initiatives under the Shark Research Plan is the Shark Tagging Metadatabase Project.  This project is designed to identify sources of biological information for highly migratory shark species through gathering and storing of information about shark tagging.  Our aim is not to compile actual tag tracking data, but rather to compile metadata such as the numbers of species and tags attached and recovered, the study area and the type of tag.  These metadata will be stored in a database and made freely available online at the conclusion of the project through the SPC website.  As these data may be useful in identifying new information for our ongoing stock assessments, we need to work quickly to gather and understand what shark tag may be available and produce the database by the end of June 2011.  At the same time, we also hope this metadatabase can assist those who recover tagged sharks or unattached tags to return them to the researchers who attached them.  In the longer term, we hope that the database can inform researchers about the existence of similar tagging programmes in other parts of the Pacific and identify data gaps for various species and areas.

downloadlink of the excel-file

We would like to request your assistance in providing some information about tags attached to sharks in the Pacific by you or your colleagues.  A suggested list of data fields is provided in the attached spreadsheet.  Please feel free to modify these fields to reflect the available data, or to add new fields if necessary.  If you do not hold any shark tagging information but can refer us to other researchers who may, we would greatly appreciate hearing from you.

 

This project is being coordinated at SPC by Ms Lea Protoy so please contact her if you have any questions or require further information.  We would be happy to assist you in whatever way we can in finding ways to receive your metadata without taking up large amounts of your time (e.g. linkages to existing web databases).  Thank you in advance for your consideration and we look forward to hearing from you!

 

Best wishes,

 

Shelley Clarke and Lea Protoy

New to nature No 31: Chlamydoselachus africana

This is the first species of frilled shark discovered since 1884

    namibia-shark Chlamydoselachus africana, found off the coast of Namibia

    Chlamydoselachus africana is the second known species of the shark family Chlamydoselachidae.

    Caught off the coast of Namibia, this newly discovered shark appears to feed on smaller sharks and squid. Its snakelike head and long, distensible jaws with multiple needle-like, inwardly directed spines on its teeth are capable of snagging prey as large as half its own body length.

    The only other species of frilled shark, such as this is, was discovered in 1884 off the coast of Japan.

    Whether this new shark is geographically widespread like its sister species is yet to be determined. Both species are known to inhabit only very deep waters, from 550m to around 900m.

ScienceDaily (Feb. 28, 2011) — A study led by scientists at the University of Miami (UM) Rosenstiel School of Marine & Atmospheric Science details the first scientific research to successfully track a great hammerhead shark using satellite tag technology.


Rosenstiel Schhol Research Assistant Professor Neil Hammershlag and colleagues tracked one of the nomadic sharks for 62 days to uncover its northeast journey from the coast of South Florida to the middle of the Atlantic off the coast of New Jersey. The straight line point-to-point distance of 1,200 kilometers (745 miles) represents a range extension for this species. The data also revealed the shark entering the Gulf Stream current and open-ocean waters of the northwestern Atlantic Ocean.

"This animal made an extraordinary large movement in a short amount of time," said Hammerschlag, director of the R.J. Dunlap Marine Conservation Program at the UM Rosenstiel School. "This single observation is a starting point, it shows we need to expand our efforts to learn more about them."

The animal was likely following food, such as mahi-mahi and jacks, off the continental slope and into the Gulf Stream, according to the authors.

This preliminary study is part of a larger effort by Hammerschlag to satellite track tropical sharks to identify hotspots -- areas that are important for feeding, mating, and pupping -- and to document their largely unknown migration routes. In the last year, the R.J. Dunlap team has tagged the fins more than 50 large and environmentally threatened sharks in Florida and Bahamas, among them great hammerhead, bull and tiger sharks.

The great hammerhead shark is listed as endangered in the northwest Atlantic and Gulf of Mexico by the International Union for Conservation of Nature (ICUN) due to a suspected population decline of nearly 50 percent over the last 10 years. The shark is found in tropical waters worldwide and is under threat of extinction due to overfishing for its large fins, which are prized for shark fin soup, and from accidental bycatch from commercial fishing operations.

"This study provides evidence that great hammerheads can migrate into international waters, where these sharks are vulnerable to illegal fishing," said Hammerschlag. "By knowing the areas where they are vulnerable to exploitation we can help generate information useful for conservation and management of this species."

DNA analysis of great hammerhead fins sold in the Asian shark fin market has shown that a large majority of the sharks came from Atlantic waters.

The paper was published in the current issue of the journal Endangered Species Research.
