This meeting included a joint day with the Working Group on Ballast Water and Other Ship Vectors (WGBOSV). The meeting was hosted by Judy Pederson (USA) and chaired by Cynthia McKenzie (Canada). The meeting was attended by 23 scientists in person, two by web-conference and five by correspondence, representing 16 countries; four additional scientists attended on the joint meeting day. The objective of the meeting was to communicate new information and discuss several aspects of the introductions and transfers of marine organisms relevant to the six terms of reference for the working group. There was a particular focus on introductions into the Arctic environment, bio- fouling of vessels and structures, and developing indicators to evaluate impact of non- indigenous species in marine environments. This year’s interim report provides: a summary of the 16 National Reports (reports at- tached in Annex 4); the 20 presentations provided by members and chair invited mem- bers in support of term of reference objectives (abstracts provided in Annex 5); discussions, achievements, limitations and a recommendation. All Terms of Reference were discussed with this report structured so that each Term of Reference is dealt with in sequential order. The National Reports provide an overview of the priorities, findings, meetings and publications for each country. In addition, it provides discussion points for methodologies, collaborations and knowledge gaps that need to be addressed by the group (ToR a). The AquaNIS database continues to be updated and the data is now georeferenced. There were three additional presentations under this term of reference addressing monitoring methodology and an invasion risk assessment tool. WGITMO considered two ToRs jointly with WGBOSV: examining the effect of climate change on the establishment of aquatic species in the Arctic (ToR b); and examining bio- fouling as vector for the introduction and transfer of aquatic organisms on vessels and structures (ToR c). An update was provided on an ongoing initiative to address De- scriptor 2 of the EU-MSFD, in particular Indicator 2.2.1 regarding impact of Invasive Al- ien Species (IAS) on marine environments (ToR d). The final goal is to develop a new indicator of impact that can be proposed for the implementation within the Marine Strat- egy Framework Directive. Two ICES Cooperative Research Reports developed by WGITMO were recently released. One was an alien species alert report on the invasive tunicate Didemnum vexillum and the other summarized the status of non-indigenous ma- rine species in the North Atlantic and adjacent waters 2003–2007 (ToR a). An update was provided on communications regarding the Suez Canal enlargement and bioinvasion problems in the Mediterranean Sea. A theme session for the 2017 ICES ASC on bioinvasion trajectories and impacts in con- trasting marine environments was proposed by WGITMO as collaboration between IC- ES-PICES-CIESM. The proposal was accepted and will be jointly chaired by representatives of the three groups.

Year 2 Working on all ToRs, but with special focus on ToRs a, c, and e. Year 3 Report on all ToRs 4 List of Outcomes and Achievements of the WG in this delivery period • A review of national activities (16 countries) was conducted to advance re- search, develop collaborations and address surveillance and knowledge gaps in issue related to the introduction and transfer of marine organisms. • It was noted that in both the United States and Canada there were no new spe- cies reported in 2016. However, in Europe several countries reported new sightings including the invasive tunicate Didemnum vexillum in Germany and a new location on an oyster farm in the United Kingdom (Scotland). • The AquaNIS database continues to be the main repository of new non- indigenous species data with each country updating the database annually. Georeferenced data can soon now be stored which will address the needs of OSPAR and other potential users. • Numerous papers and reports have been published collaboratively among working group researchers that have addressed ToR objectives including pub- lications in Nature and other journals. • Two ICES Cooperative Research Reports developed by WGITMO were recent- ly released; an Alien Species Alert on Didemnum vexillum Kott, 2002: Invasion, impact and control CRR#335 and a report on the status of introductions of non-indigenous marine species in the North Atlantic and adjacent waters 2003–2007 CRR#334. • Working group members participated in testing the AS-ISK risk assessment tool and results of this study were discussed, including implications for use. • A theme session for the 2017 ICES ASC on bioinvasion trajectories and impacts in contrasting marine environments will be chaired jointly by ICES-PICES- CIESM. • A scientific

CUESTA2,4) 1) Biologie I, Universität Regensburg, D-93040 Regensburg, Germany 2) Instituto de Ciencias Marinas de Andalucía, CSIC, Avenida República Saharaui, 2, E-11519 Puerto Real, Cádiz, Spain ABSTRACT A molecular and morphological analysis of representatives of the family Plagusiidae, including all members of Plagusia Latreille, 1804, and the recently established Davusia Guinot, 2007, was carried out. Due to marked differences in adult and larval morphology, as well as mitochondrial and nuclear DNA, two species of Plagusia,viz.,P. chabrus (Linnaeus, 1758), and P. dentipes De Haan, 1835, are considered sister taxa but distinct from other members of the genus. They are transferred to a new genus, Guinusia. A molecular phylogeny suggests that Guinusia is not closer related to Plagusia than to the plagusiid genera Euchirograpsus H. Milne Edwards, 1853, and Miersiograpsus Türkay, 1978. Furthermore, with new evidence from mitochondrial and nuclear DNA as well as a reappraisal of the larval morphology, the genus Percnon Gistel, 1848, is formally removed from the Plagusiidae and recognized as a separate family, Percnidae Števciˇ c,´ 2005.

  • Stock Assessment of Nehu, Encrasicholina Purpurea, Using the Egg Production Method
    BULLETIN OF MARINE SCIENCE 53(21: 768-777. 1993 STOCK ASSESSMENT OF NEHU, ENCRASICHOLINA PURPUREA, USING THE EGG PRODUCTION METHOD D.A. Somerton, D. R. Kobavashi and K. C.Landgraf ABSTRACT Nehu. Encrusicholina purpurea. are short lived. tropical anchovies used as baitfish for the Hawaiian pole-and-line tuna fishery. The spawnlng biomass of nehu within Pearl Harbor. Hawaii, was estimated weekly using the Daily Egg Produalon Method (DEPM). Over the 2-year studv period. spawning biomass vaned between 0.5 and 5.0 mctnc tons in response to the intensive fishery and a seasonal cyclicity In reproductive effort. Nehu, Encrasicholina purpurea. are among the smallest of anchovies. yet they are commercially valuable as the primary bait used by the Hewzii:tn pole-and- line fishery for skipjack tuna, Katsuwonw pehmis (Uchidz.. 197'7). Similar to other stolephorid baitfishes (Dalzell. 1987), nehu ?.re exrrzirdy short lived (<6 months; Struhsaker and Uchiyarna. 1976) and spawn almost continuously throughout the year (Tester. 1952: Clarke. 1987, 1989). Unlike the others, nehu occur exclusively within estuarine embayments, migrating daily between diurnal resting areas along turbid shorelines and nocturnal spawning areas in relatively clear channels. The commercial fishery exploits this unusual behavior. and is thereby unique among baitfish fisheries. by using seines to capture nehu in their shallow daytime habitat (Uchida, 1977; Dalzell and Lewis, 1989). Nehu abundance has fluctuated over time and occasionally has declined to such an extent that vessels have spent nearly as much time fishing for bait as for tuna. The economic hardships resulting from the periodic shortages of nehu precipitated early efforts at stock assessment using either egg and larva data (Tester, 1951, 1952) or commercial catch statistics (Bachman.

Abstract Otolith morphometrics, coupled with image analysis and mathematical equations were examined to investigate stock structure of Anchovy, Encrasicholina punctifer on Persian Gulf and Oman Sea. Samples (360 Otolith) were collected during December and January 2012 from three main fisheries landing including Gheshm, Garze and Jask. The structure of transverse sagittal otolith sections were described for individual anchovy samples by using Image motic software. The measured parameters for each otolith were: length, width, weight, perimeter and area. In addition, the morphological indices of otoliths including roundness, oval and circular indices were measured by mathematical equations. Results from this study showed a similarity in morphological and morphometric parameters of Otoliths of anchovy stocks collected from Gheshm, Garze and Jask. Therefore, theses three populations could be considered as single population.

For over 140 years, convergent evolution of the crab-like body plan (with a wide and flattened shape, and a bent abdomen) at least five times in decapod crustaceans has been known as ‘carcinization’. The repeated loss of this body plan has been identified as ‘decarcinization’. We offer phylogenetic strategies to include poorly known groups, and direct evidence from fossils, that will resolve the pattern of crab evolution and the degree of phenotypic variation within crabs. Proposed ecological advantages of the crab body are summarized into a hypothesis of phenotypic integration suggesting correlated evolution of the carapace shape and abdomen. Our premise provides fertile ground for future studies of the genomic and developmental basis, and the predictability, of the crab-like body form.

    Aspects of taxonomy and life history traits of engraulids in the context of biodiversity conservation and fisheries management 19 Ganga, U Pelagic Fisheries Division, CMFRI, Kochi-18 Engraulids are a major small pelagic resource abundant in at about mid-body, pectoral fins low on the sides, abdominal the tropical and temperate seas of the world. The prominent pelvic fins originating before or below the dorsal-fin base, a snout which is characteristic of this family carries a unique forked tail (except in rattail anchovy Coilia) and a wide silvery organ called the “rostral organ”. They are small, silvery stripe along the mid-sides. The body has no lateral line and coloured small pelagics with more than 16 genera and 139 is covered in smooth, often weakly attached cycloid scales. species identified worldwide (Nelsen, 1984) of which 4 genera namely, Anchoa (35 species), Anchoviella (15 species), Stolephorus (19 species) and Thryssa (25 species) constitute the majority of species. They form a major fishery resource in the coastal fisheries of the Indian EEZ. In 2013 the dominant group among anchovies contributing to commercial fisheries were the whitebaits with an estimated 69500 t landed, followed by the other anchovies such as Thryssa (42000 t), Coilia (30767 t) and Setipinna (8507 t). Correct identification of fishes, their eggs and larvae are thus crucial in fisheries management. Classification Class: Actinopterygii Fig. 2.

New Technologies in Conservation Research and Management Abstract Directors from the Waikiki Aquarium (Dr. Andrew Rossiter), Maui Ocean Center (Tapani Vouri) and the Bishop Museum (Melanie Ide) will discuss their programs public conservation programs and what the future holds for these institutions both during and after COVID-19. Panelists will discuss: How these institutions survived during COVID-19, what they will be doing in the future to ensure their survival and how they promote and support conservation efforts in Hawai'i. HCC is an excellent opportunity to showcase how Hawaii's largest aquaria and museums play a huge role in building awareness of the public in our biocultural diversity both locally and globally, and how the vicarious experience of biodiversity that is otherwise rarely or never seen by the normal person can be appreciated, documented, and researched, so we know the biology, ecology and conservation needs of our native biocultural diversity. Questions about how did COVID-19 affect these amazing institutions and how has COVID-19 forced an internal examination and different ways of working in terms of all of the in-house work that often falls to the side against fieldwork, and how it strengthened the data systems as well as our virtual expression of biodiversity work when physical viewing became hampered.

Le crabe plat des oursins Percnon gibbesi (Milne-Edwards H., 1853). in Muséum national d'Histoire naturelle [Ed.], 20 juillet 2015. Inventaire national du Patrimoine naturel, 10 pp., site web http://inpn.mnhn.fr Contact de l'auteur : Pierre Noël, SPN et DMPA, Muséum national d'Histoire naturelle, 43 rue Buffon (CP 48), 75005 Paris ; e-mail [email protected] Résumé Percnon gibbesi est un crabe très plat. Sa carapace est à peine plus longue que large, et sa longueur mesure jusqu'à 39 mm chez les mâles, 34 mm chez les femelles et entre 26 et 30 mm chez les femelles ovigères. Elle porte trois dents au niveau du front et quatre dents antérolatérales pointues. Chaque patte ambulatoire est munie d'une rangée de fortes épines sur la marge antérieure du mérus. Les pinces des mâles sont inégales et plus fortes que celles des femelles ou des juvéniles. La couleur générale est brunâtre-rougeâtre. Ce crabe furtif est actif le jour. C'est un herbivore plus ou moins strict. Les femelles sont ovigères en saison chaude ; le développement larvaire comporte 6 stades zoé et une mégalope.
