Lamna Nasus) Inferred from a Data Mining in the Spanish Longline Fishery Targeting Swordfish (Xiphias Gladius) in the Atlantic for the 1987-2017 Period
SCRS/2020/073 Collect. Vol. Sci. Pap. ICCAT, 77(6): 89-117 (2020) SIZE AND AREA DISTRIBUTION OF PORBEAGLE (LAMNA NASUS) INFERRED FROM A DATA MINING IN THE SPANISH LONGLINE FISHERY TARGETING SWORDFISH (XIPHIAS GLADIUS) IN THE ATLANTIC FOR THE 1987-2017 PERIOD J. Mejuto1, A. Ramos-Cartelle1, B. García-Cortés1 and J. Fernández-Costa1 SUMMARY A total of 5,136 size observations of porbeagle were recovered for the period 1987-2017. The GLM results explained very moderately the variability of the sizes considering three main factors, suggesting minor but significant differences in some cases especially for the year factor and non-significant differences in other factors depending on the analysis. The greatest differences in the standardized mean length between some zones were caused by some large fish of unidentified sex. The standardized mean length data for the northern zones showed stability throughout the time series, very stable range of mean values and very few differences between sexes. The size distribution for northern areas indicated an FL-overall mean of 158 cm. The size showed a normal distribution confirming that a small fraction of individuals of this stock/s is available in the oceanic areas where the North Atlantic fleet is regularly fishing and the fishes are not fully recruited to those areas and / or this fishing gear up to 160 cm. The data suggests that some individuals could sporadically reach some intertropical areas of the eastern Atlantic. RÉSUMÉ Un total de 5.136 observations de taille de requins-taupes communs ont été récupérées pour la période 1987-2017. Les résultats du GLM expliquent très modérément la variabilité des tailles en tenant compte de trois facteurs principaux, ce qui suggère des différences mineures mais significatives dans certains cas, notamment pour le facteur année et des différences non significatives pour d'autres facteurs selon le type d’analyse. -

Over 10,500 names are treated including 6,793 valid species and subspecies (with 1,907 primary synonyms), 1,271 genera and subgenera (with 393 primary synonyms), 93 families and 38 superfamilies. Nomenclatural and taxonomic problems are reviewed in detail, and many resolved. Detailed notes and references are provided where necessary. The constitution of a large number of families and superfamilies is discussed in detail, with the positions of some taxa rearranged in an attempt to form a stable base for future taxonomic studies. This is the first time the nomenclature of any large group of decapod crustaceans has been examined in such detail.

Porbeagle TAC Fact Sheet 2008
Fact Sheet: Porbeagle Sharks Porbeagle sharks are: • exceptionally slow-growing and vulnerable to overfishing • heavily exploited for their valuable meat and fins • classified by IUCN as Critically Endangered off Europe • highly migratory but unprotected in international waters • legally fished in Europe counter to scientific advice, and • in urgent need of conservation measures. Biology Porbeagle sharks are exceptionally vulnerable to overexploitation and long lasting depletion due to their slow growth, late maturity, and small litters. Females do not reproduce until their teen years and give birth to only about four pups after an 8-9 month pregnancy. Like most sharks, porbeagles are top predators in marine food webs and therefore critical to keeping the ocean in balance. Fisheries today Porbeagle meat is among the most prized of all shark meat, particularly in Europe. The large fins of porbeagles are valuable for use in “shark fin soup”, an Asian delicacy. Schools of porbeagle sharks are therefore sporadically targeted, but also often kept if taken incidentally, as “bycatch”, usually by pelagic longliners. Scientists note that most hooked porbeagle sharks make it to the boat alive; many could therefore survive capture if released. Currently, vessels from France and Spain take most of the EU catch of porbeagles, through targeted fisheries and as bycatch. Boats from the UK and Ireland also land porbeagle sharks taken incidentally. Population status Intense fishing has left the Northeast Atlantic porbeagle shark stock the most depleted porbeagle population in the world. Norwegian landings from this region declined by 99% between 1936 and 2005. The IUCN-World Conservation Union includes porbeagle on their Red List of Threatened Species, as Vulnerable globally; the Northeast Atlantic population is classified as Critically Endangered. -
Porbeagle Shark Fact Sheetforthe16 Overview Regional Efforts Toward Recovery Andsustainableuse
Fact sheet for the 16th Meeting of the Conference of the Parties (CoP16) to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) Porbeagle shark PROPOSAL Lamna nasus # 44 Proposed action Listing on CITES Appendix II Lead proponent European Union Co-sponsors Brazil, Comoros, Croatia, Egypt Annotation Entry into effect delayed by 18 months to allow Parties to resolve technical and administrative issues ANDY MURCH Overview The porbeagle is a globally threatened, low-productivity shark that has been seriously overfished in major parts of its range primarily for international trade in meat and fins. Strong demand for these products continues to drive targeted and incidental take of porbeagles that is inadequately managed or completely unregulated. CITES Appendix II listing is warranted to facilitate compliance with relevant fishing restrictions and establishment of science-based export limits, thereby complementing national and regional efforts toward recovery and sustainable use.

Atlantic Sharks at Risk
RESEARCH SERIES JUNE 2008 Risk Assessment Prompts No-Take Recommendations for Shark Species ATLANTIC SHARKS AT RISK SummARY OF AN EXPERT WORKING GROup REPORT: Simpfendorfer, C., Heupel M., Babcock, E., Baum, J.K., Dudley, S.F.J., Stevens, J.D., Fordham, S., and A. Soldo. 2008. Management Recommendations Based on Integrated Risk Assessment of Data-Poor Pelagic Atlantic Sharks. POpuLATIONS OF MANY of the world’s pelagic, or open ocean, shark and ray species are declining. Like most sharks, these species are known to be susceptible to overfishing due to low reproductive rates. Pelagic longline fisheries for tuna and swordfish catch significant numbers of pelagic sharks and rays and shark fisheries are also growing due to declines in traditional target species and the rising value of shark fins and meat. Yet, a lack of data has prevented scientists from conducting reliable population assessments for most pelagic shark and ray species, hindering effective management actions. Dr. Colin Simpfendorfer and the Lenfest Ocean Program convened an international expert working group to estimate the risk of overfishing for twelve species caught in Atlantic pelagic longline fisheries under the jurisdiction of the International Commission for the Conserva- tion of Atlantic Tunas (ICCAT). The scientists conducted an integrated risk assessment designed for data-poor situations for these sharks and rays. Their analysis indicated that bigeye thresher, shortfin mako and longfin mako sharks had the highest risk of overfishing while many of the other species had at least moderately high levels of risk. Based on these results, the scientists developed recommendations for limiting or prohibiting catch for the main pelagic shark and ray species taken in ICCAT fisheries.
