Greenland Shark (Somniosus Microcephalus)
Greenland shark (Somniosus microcephalus) feeding behavior on static fishing gear, effect of SMART (Selective Magnetic and Repellent-Treated) hook deterrent technology, and factors influencing entanglement in bottom longlines Scott M. Grant1, Rennie Sullivan1 and Kevin J. Hedges2 1 Centre for Sustainable Aquatic Resources, Memorial University of Newfoundland, St. John’s, NL, Canada 2 Central and Arctic Region, Arctic Aquatic Research Division, Fisheries and Oceans Canada, Winnipeg, MB, Canada ABSTRACT The Greenland Shark (Somniosus microcephalus) is the most common bycatch in the Greenland halibut (Reinhardtius hippoglossoides) bottom longline fishery in Cumberland Sound, Canada. Historically, this inshore fishery has been prosecuted through the ice during winter but winter storms and unpredictable landfast ice conditions since the mid-1990s have led to interest in developing a summer fishery during the ice-free season. However, bycatch of Greenland shark was found to increase substantially with 570 sharks captured during an experimental Greenland halibut summer fishery (i.e., mean of 6.3 sharks per 1,000 hooks set) and mortality was reported to be about 50% due in part to fishers killing sharks that were severely entangled in longline gear. This study investigated whether the SMART (Selective Magnetic and Repellent-Treated) hook technology is a practical deterrent to Greenland shark predation and subsequent bycatch on bottom longlines. Greenland Submitted 1 December 2017 shark feeding behavior, feeding kinematics, and variables affecting entanglement/ 22 April 2018 Accepted disentanglement and release are also described.

These sharks closely resemble each other, have overlapping geographical ranges and are difficult to identify by morphological characters. Non-metric multidimensional scaling of morphometric variables indicates a clear separation between the two species, with 10 characters each contributing 2Á12–2Á45% of the total variability between species. Maximum likelihood, parsimony and neighbour-joining trees revealed two major mtDNA haplotype clades, corresponding to the two species, with an average corrected sequence divergence between them of 3Á39 Æ 0Á56%. Within species divergences between haplotypes averaged 0Á27 Æ 0Á18% in G. melastomus and 0Á12 Æ 0Á08% in G. atlanticus. A total of 35 diagnostic nucleotide site differences and four restriction fragment length polymorphism recognition sites in the ND2 gene can be used to distinguish the two species. -

A5 By-catch Species APPENDIX 5: BY-CATCH SPECIES A.5 By-catch species By-catch is the unintentional/incidental capture of non-target species during fishing operations. Different types of fisheries have different types and levels of by-catch, depending on the gear used, the time, area and depth fished, etc. Article IV of the Convention states: "the Commission shall be responsible for the study of the population of tuna and tuna-like fishes (the Scombriformes with the exception of Trichiuridae and Gempylidae and the genus Scomber) and such other species of fishes exploited in tuna fishing in the Convention area as are not under investigation by another international fishery organization". The following is a list of by-catch species recorded as being ever caught by any major tuna fishery in the Atlantic/Mediterranean. Note that the lists are qualitative and are not indicative of quantity or mortality. Thus, the presence of a species in the lists does not imply that it is caught in significant quantities, or that individuals that are caught necessarily die.

“Trophic Strategies and Basic Morphology of the Rare Demersal Kitefin Shark Dalatias Licha in the North- Western Mediterranean Sea”
“Trophic strategies and basic morphology of the rare demersal kitefin shark Dalatias licha in the north- western Mediterranean Sea” Mª Lourdes López Calero Master in Marine Sciences: Oceanography and Marine Environment Management Directores: Tutor: Dra. Marta Coll Montón y Dr. Joan Dr. Joan Baptista Company Claret Navarro Bernabé Departamento de Recursos Marinos Departamento de Recursos Marinos Renovables Renovables Instituto de Ciencias del Mar - CSIC Instituto de Ciencias del Mar - CSIC September 2013 Abstract At the present time unravelling the complexity of marine food webs has become a valuable tool to progress on the knowledge on how marine ecosystems are structured and how the function. Recently, to the study of species trophic ecology, has been applied a combination of two complementary methodologies, stomach content and stable isotope analyses With the present study I aimed at examining the trophic ecology and other biological traits of the kitefin shark Dalatias licha in the north-western Mediterranean Sea. A demersal shark which has been assessed as near threaten globally and data deficient in the Mediterranean Sea within the IUCN framework. In this study I provide morphological measures and also new information on its diet composition, trophic ecology and trophic level of this organism by means of stomach content analysis, providing dietary quantitative indexes (%F, %N and %IRI), and stable isotopes analysis by measuring δ15N and δ13C isotopic values and applying Bayesian isotopic mixing models. Also potential differences in dietary habits and basic morphology between sexes and different study areas were examined. Results show alimentary preference for small demersal sharks, followed by bony fishes, which could be a symptom of a dietary shift from fishes that were the main prey 30 years ago. -
(Squalus Acanthias) and Black Dogfish (Centroscyllium Fabricii) Spanish Data (Surveys and Fishery) in NAFO Divisions 3LMNO
NOT TO BE CITED WITHOUT PRIOR REFERENCE TO THE SECRETARIAT Northwest Atlantic Fisheries Organization Serial No. N5250 NAFO SCR Doc. 06/30 SCIENTIFIC COUNCIL MEETING – JUNE 2006 Spiny Dogfish (Squalus acanthias) and Black Dogfish (Centroscyllium fabricii) Spanish Data (Surveys and Fishery) in NAFO Divisions 3LMNO. by F. González-Costas1, D. González-Troncoso1, M. Casas1 and G. Ramilo1 1 Instituto Español de Oceanografía, Vigo, Spain ABSTRACT The analysis of Spanish survey and fishery data from Divisions 3LMNO show that Spiny dogfish (Squalus acanthias) is not abundant and that this species appears in these Divisions sporadically and in depths of less than 500 meters. Black dogfish (Centroscyllium fabricii) data show that this species is present in all Divisions, but is more abundant in Div. 3NO and in depths of more than 900 m. Biomass estimated from the 3NO survey displays an increasing trend over the last three years. Commercial catches of this species are mainly a by-catch of the Greenland halibut fishery in Div. 3LMNO. Size compositions are mainly in between 50 and 70 cm of length, both for commercial and survey catch es. INTRODUCTION The aim of this paper is to review and present the Spanish information from surveys and commercial data for Spiny dogfish (Squalus acanthias) and Black dogfish (Centroscyllium fabricii) that were requested to the NAFO Scientific Council, in accord with the recommendation from the 2002 NAFO Symposium on Elasmobranches Fisheries. Part of this information had been presented by P. Duran et al. in 1999 for the period 1999-1998. MATERIAL AND METHODS Two sources of information have been used in this paper, data recorded by the National Scientific Observers and research survey dat a. -

Identification Guide to the Deep-Sea Cartilaginous Fishes Of
Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean FAO. 2015. Identification guide to the deep–sea cartilaginous fishes of the Southeastern Atlantic Ocean. FishFinder Programme, by Ebert, D.A. and Mostarda, E., Rome, Italy. Supervision: Merete Tandstad, Jessica Sanders (FAO, Rome) Technical editor: Edoardo Mostarda (FAO, Rome) Colour illustrations, cover and graphic design: Emanuela D’Antoni (FAO, Rome) This guide was prepared under the “FAO Deep–sea Fisheries Programme” thanks to a generous funding from the Government of Norway (Support to the implementation of the International Guidelines on the Management of Deep-Sea Fisheries in the High Seas project) for the purpose of assisting states, institutions, the fishing industry and RFMO/As in the implementation of FAO International Guidelines for the Management of Deep-sea Fisheries in the High Seas. It was developed in close collaboration with the FishFinder Programme of the Marine and Inland Fisheries Branch, Fisheries Department, Food and Agriculture Organization of the United Nations (FAO). The present guide covers the deep–sea Southeastern Atlantic Ocean and that portion of Southwestern Indian Ocean from 18°42’E to 30°00’E (FAO Fishing Area 47). It includes a selection of cartilaginous fish species of major, moderate and minor importance to fisheries as well as those of doubtful or potential use to fisheries. It also covers those little known species that may be of research, educational, and ecological importance. In this region, the deep–sea chondrichthyan fauna is currently represented by 50 shark, 20 batoid and 8 chimaera species. This guide includes full species accounts for 37 shark, 9 batoid and 4 chimaera species selected as being the more difficult to identify and/or commonly caught.
