This study analysed four groundfish biomass surveys (POKER 1–4) conducted from 2006 to 2017 across depths ranging from 100 to 1 000 m. Forty demersal species were recorded in total and density distributions of twenty presented. However, only seven species account for the majority of the biomass (96%). Total biomass was 250 000 tonnes during the first three surveys (POKER 1–3), and 400 000 tonnes for POKER 4 due to a high catch of marbled notothen (Notothenia rossii) and mackerel icefish (Champsocephalus gunnari) (accounting for 44% and 17% of the 400 000 tonnes biomass respectively). -

Vulnerable Marine Ecosystems Database Newfoundland Seamounts Geographical reference Northwest Atlantic Management Body/Authority Northwest Atlantic Fisheries Organization (NAFO) Area Type Seamount closure (NAFO) Closed since 2007-01-01 until 2021-12-31 Habitat and Biology General Biology Seamounts are uniquely complex habitats that rise into bathyal and epi-pelagic depths. In general seamounts, owing to their isolation tend to support endemic populations and unique faunal assemblages. Physical description of the environment: Seamounts Newfoundland Seamounts consist of 6 peaks with summits all deeper than 2400 m, with most of the area being deeper than 3500m. The Newfoundland seamounts were volcanically active in the late Cretaceous period. Named seamounts include Shredder and Scruntion.

The Marine Board was established in 1995 to facilitate enhanced cooperation between European marine science organizations towards the development of a common vision on the research priorities and strategies for marine science in Europe. Members are either major national marine or oceanographic institutes, research funding agencies, or national consortia of universities with a strong marine research focus. In 2015, the Marine Board represents 36 Member Organizations from 19 countries. The Board provides the essential components for transferring knowledge for leadership in marine research in Europe. Adopting a strategic role, the Marine Board serves its member organizations by providing a forum within which marine research policy advice to national agencies and to the European Commission is developed, with the objective of promoting the establishment of the European marine Research Area. www.marineboard.eu European Marine Board Member Organizations UNIVERSITÉS MARINES Irish Marine Universities National Research Council of Italy Consortium MASTS Delving Deeper: Critical challenges for 21st century deep-sea research European Marine Board Position Paper 22 This position paper is based on the activities of the European Marine Board Working Group Deep-Sea Research (WG Deep Sea) Coordinating author and WG Chair Alex D. -

Area-restricted search patterns and dive behaviour were established from location data gathered by CTD satellite- relayed data loggers. At-sea movements of the seals demonstrated that >40% of the juvenile ele- phant seal population tagged use the Kerguelen Plateau during the austral winter. Search activity increased where temperature at 200 m depth was lower, when closer to the shelf break, and, to a lesser extent, where sea-surface height anomalies were higher. However, while this model explained the observed data (F1,242 = 88.23, p < 0.0001), bootstrap analysis revealed poor predic- tive capacity (r2 = 0.264). There appears to be potential overlap between the seals and commercial fishing operations in the region. This study may therefore support ecosystem-based fisheries man- agement of the region, with the aim of maintaining ecological integrity of the shelf.

New Records of Fishes from the Hawaiian Islands!
Pacific Science (1980), vol. 34, no. 3 © 1981 by The University Press of Hawaii. All rights reserved New Records of Fishes from the Hawaiian Islands! JOHN E. RANDALL 2 ABSTRACT: The following fishes represent new records for the Hawaiian Islands: the moray eel Lycodontis javanicus (Bleeker), the frogfish Antennarius nummifer (Cuvier), the jack Carangoides ferdau (Forssk::U), the grouper Cromileptes altivelis (Cuvier) (probably an aquarium release), the chubs Kyphosus cinerascens (Forsskal) and K. vaigiensis (Quoy and Gaimard), the armorhead Pentaceros richardsoni Smith, the goatfish Upeneus vittatus (Forsskal) (a probable unintentional introduction by the Division of Fish and Game, State of Hawaii), the wrasse Halichoeres marginatus Ruppell,' the gobies Nemateleotris magnifica Fowler and Discordipinna griessingeri Hoese and Fourmanoir, the angelfish Centropyge multicolor Randall and Wass, the surgeonfish Acanthurus lineatus (Linnaeus), the oceanic cutlassfish Assurger anzac (Alexander), and the driftfish Hyperoglyphe japonica (Doderlein). In addition, the snapper Pristipomoides auricilla (Jordan, Evermann, and Tanaka) and the wrasse Thalassoma quinquevittatum (Lay and Bennett), both overlooked in recent compilations, are shown to be valid species for the Hawaiian region. Following Parin (1967), the needlefish Tylosurus appendicu latus (Klunzinger), which has a ventral bladelike bony projection from the end of the lower jaw, is regarded as a morphological variant of T. acus (Lacepede). IN 1960, W. A. Gosline and V. E.

Conger myriaster (Brevoort), which are caught rather plentifully, having high commercial value, in the coastal waters off southern Japan. Chapter I. Larva and elver of the conger eel A good many young of the conger eel, including larva and elver stages, were caught in the Sea of Suo-nada, a western part of the Inland Sea of Japan, and were used in the study of their morphological transformation as they grew up. ( I ) When the conger larve hatches out, it develops into the elver stage through the semi-larva and semi-elver stages. The larva, from the time it is hatched out until it is a full grown leptocephalus, is called the developing stage, being constitut ed of early, middle and last. While the shrinking course from a full grown to a minimum size is called the metamorphosis stage, being constituted also of three stages (early, middle and last), of w'hich the first two are called semi-larva, and the last semi-elver, which is further classified into four sub-stages (Table 25)- (2) The larvae enter their metamorphosis stage when they grew up to 120 mm in body length, and they enter to the elver stage when their body length shrinked to 65 mm. -
Microsatellite Markers for the Notothenioid Fish Lepidonotothen
Papetti et al. BMC Res Notes (2016) 9:238 DOI 10.1186/s13104-016-2039-x BMC Research Notes SHORT REPORT Open Access Microsatellite markers for the notothenioid fish Lepidonotothen nudifrons and two congeneric species Chiara Papetti1*, Lars Harms1, Jutta Jürgens1, Tina Sandersfeld1,2, Nils Koschnick1, Heidrun Sigrid Windisch1,3, Rainer Knust1, Hans‑Otto Pörtner1 and Magnus Lucassen1 Abstract Background: Loss of genetic variability due to environmental changes, limitation of gene flow between pools of individuals or putative selective pressure at specific markers, were previously documented for Antarctic notothenioid fish species. However, so far no studies were performed for the Gaudy notothen Lepidonotothen nudifrons. Starting from a species-specific spleen transcriptome library, we aimed at isolating polymorphic microsatellites (Type I; i.e. derived from coding sequences) suitable to quantify the genetic variability in this species, and additionally to assess the population genetic structure and demography in nototheniids. Results: We selected 43,269 transcripts resulting from a MiSeq sequencer run, out of which we developed 19 primer pairs for sequences containing microsatellite repeats. Sixteen loci were successfully amplified in L. nudifrons. Eleven microsatellites were polymorphic and allele numbers per locus ranged from 2 to 17. In addition, we amplified loci identified from L. nudifrons in two other congeneric species (L. squamifrons and L. larseni). Thirteen loci were highly transferable to the two congeneric species. Differences in polymorphism among species were detected. Conclusions: Starting from a transcriptome of a non-model organism, we were able to identify promising polymor‑ phic nuclear markers that are easily transferable to other closely related species. These markers can be a key instru‑ ment to monitor the genetic structure of the three Lepidonotothen species if genotyped in larger population samples.
