KAnuRA3 ABSTRACT: The first occurrence of the rare viper shark, Trigonognathus ka­ beyai, from the central Pacific Ocean is reported. Morphometries are compared between this specimen and the type specimens from Japan, and this specimen differs from the types in only a few measurements. The poor preservation of this specimen precluded examination of internal anatomy. THE SHARK Trigonognathus kabeyai belongs (Pseudopentaceros wheeleri) aboard the to a recently described genus and species in NOAA ship Townsend Cromwell at 29° the family Squalidae. Only three specimens, 48.0' N, 179° 04.6' E on Southeast Hancock all from Japan, have been reported since this Seamount, approximately 300 km northwest species was described in 1990 (Mochizuki ofKureAtoll, NorthwesternHawaiianIslands. and Ohe 1990, Shirai and Okamura 1992; The shark was caught in an Aberdeen bottom L. J. V. Compagno, pers. comm.). This shark trawl, which was towed east to west across differs in skeletal morphology from other the seamount at a depth of approximately squaloid sharks and is distinguished from 270 m. Towing speed was between 2.5 and similar genera by the presence of a triangular 3.0 knots (4.6-5.6 km/hr) and the trawl was jaw and long, caninelike teeth (Shirai and hauled at approximately 2200 hours.

    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.

Abstract: A litter of Squalus megalops consisting of two normal single embryos and one pair of monozygotic twin embryos was collected off southern Brazil in 1982. The single embryos were males with respectively total length (TL) of 167.1 and 173.3 mm, yolk-free body weight (YFBW) of 25.3 and 27.9 g, internal yolk weight (INTYW) of 1.3 and 2.3 g. The twin embryos were females with respectively TL of 144.1 and 146.0 mm, YFBW of 12.4 and 13.6 g, and INTYW of 0.7 and 0.6 g. The twins were conjoined by a thin cord of embryonic tissue with length of 36.0 mm and diameter of 1.5 mm, attached to the ventral body surface between the pectoral fin bases. All four embryos were similar in body proportions and in the relative weight of the internal yolk. The twins were normally conformed but their body weights were approximately half of those of the single embryos of the litter. This is explained from theory of embryonic development of the telolecithal lecitotrophic elasmobranch egg.

Despite being intensively fished in several loca- tions, biological knowledge is limited and no genetic structure information is available. This is the first study to examine the ge- netic structure of S. blainville in the Mediterranean Sea. Considering the high dispersal potential inferred for other squalid sharks, the hypothesis of panmixia was tested based on a 585 bp fragment of the mitochondrial DNA cytochrome c oxidase subunit I gene from 107 individuals and six nuclear microsatellite loci from 577 individuals. Samples were collected across the Ionian, Aegean and Libyan Seas and off the Balearic Islands. Twenty three additional sequences of Mediterranean and South African origin were retrieved from GenBank and included in the mitochondrial DNA analysis. The overall haplotype diversity was high, in contrast to the low nucleotide diversity.

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.

To cope with variable Accepted conditions of pelagic light environments they typically adjust their luminescence intensity. Here, we found 21 February 2014 evidence that bioluminescent sharks instead emit a constant light output and move up and down in the water Published column to remain cryptic at iso-luminance depth. We observed, across 21 globally distributed shark species, 10 March 2014 a correlation between capture depth and the proportion of a ventral area occupied by photophores. This information further allowed us, using visual modelling, to provide an adaptive explanation for shark photophore pattern diversity: in species facing moderate predation risk from below, counterilluminating photophores were partially co-opted for bioluminescent signalling, leading to complex patterns. In addition Correspondence and to increase our understanding of pelagic ecosystems our study emphasizes the importance of requests for materials bioluminescence as a speciation driver. should be addressed to J.M.C. (julien.m. mong sharks, bioluminescence occurs in two shark families only, the Dalatiidae (kitefin sharks) and the [email protected]) Etmopteridae (lanternsharks), which are among the most enigmatic bioluminescent organisms1–3.
