This is the first study to report a dense aggregation of juveniles of this crab, which was observed at Wollaston Island (WI) (~ 10 m). Paralomis granulosa was present on half the transects at WI (N=10), with a density of 3.1 ± 9.9 ind. m-2. Photographs from the podding event showed densities of P. granulosa ranging from 63 to 367 ind. plant-1 (190 ± 133 ind. plant-1).

Recent records of lithodid crabs in deeper waters off the Antarctic continental slope raised the question of the return of crabs to Antarctic waters, following their extinction in the lower Miocene ;15 million years ago. Antarctic cooling may be responsible for the impoverishment of the marine high Antarctic decapod fauna, presently comprising only ®ve benthic shrimp species. Effects of polar conditions on marine life, including lowered metabolic rates and short seasonal food availability, are discussed as main evolutionary driving forces shaping Antarctic diversity. In particular, planktotrophic larval stages should be vulnerable to the mismatch of prolonged development and short periods of food avail- ability, selecting against complex life cycles. We hypothesize that larval lecithotrophy and cold tolerance, as recently observed in Subantarctic lithodids, represent, together with other adaptations in the adults, key features among the life-history adaptations of lithodids, potentially enabling them to conquer polar ecosystems. The return of benthic top predators to high Antarctic waters under conditions of climate change would considerably alter the benthic communities.

  • Changes in Biomass and Chemical Composition During Lecithotrophic Larval Development of the Southern Stone Crab Paralomis Granulosa

At 6 ± 0.5°C; total larval development from hatching to metamorphosis lasted ca. 56 d, comprising 2 demersal zoeal stages and a benthic mega- lopa, with mean stage durations of 5, 11 and 45 d, respectively. All larval stages of P. granulosa are lecithotrophic, and first feeding and growth were consistently observed immediately after meta- morphosis to the first juvenile crab stage. Regardless of presence or absence of food, W, C, N, and H decreased throughout larval development. Also the C:N mass ratio decreased significantly, from 7.2 at hatching to 4.2 at metamorphosis, indicating that a large initial lipid store remaining from the egg yolk was gradually utilised as an internal energy source.

Cañete1, Javier A. Díaz-Ochoa1, Tania Figueroa1 & Alvaro Medina1 1Departamento Ciencias y Recursos Naturales, Facultad de Ciencias Universidad de Magallanes, Punta Arenas, Chile Corresponding author: Javier Díaz ([email protected]) ABSTRACT. We document latitudinal patterns of infestation of the bopyrid parasite isopod Pseudione tuberculata on southern king crab Lithodes santolla juveniles (20-77 mm carapace length) recruited to fishing grounds in the southern Chilean fjord system. Seven hundred and fifty individuals were collected by semi- autonomous diving in 11 of 21 sampling locations in the study area, along the western margin of the Magellan region between August and October 2013.The prevalence of P. tuberculata varied between 0 and ~22%, and displayed a spatial pattern associated with three areas: i) northern Beagle Channel (10 to ~22%; lengths between 37 and 47 mm), ii) northwestern Navarino Island without infestations (0%; 26-55 mm), and iii) Piazzi Island- Capitán Aracena Island (0-12%; 50-77 mm). Infestations were independent of host sex, while parasite prevalence decreased with host length. No parasites were observed on crabs longer than 60 mm. A comparison of slopes between linearized length-weight regressions suggests that parasitized individuals had lower weight growth than uninfested individuals. Both southern king crab juvenile density and P. tuberculata prevalence were higher in fishing areas towards Beagle Channel where previous research reported lower average surface water temperatures (<6.5°C) and higher surface water salinity (>30).

  • Crustáceos Decápodos (Arthropoda: Crustacea: Decapoda) De Aguas Profundas Del Pacífico Mexicano: Lista De Especies Y Material Recolectado Durante El Proyecto TALUD
    Crustáceos decápodos (Arthropoda: Crustacea: Decapoda) de aguas profundas del Pacífico mexicano: lista de especies y material recolectado durante el proyecto TALUD Michel E. Hendrickx1 INTRODUCCIÓN Los crustáceos decápodos son organismos omnipresentes en los mares y océanos de la Tierra y han sido encontrados desde la zona intermareal hasta las profundida- des abisales. Contienen los muy conocidos cangrejos, los camarones, los langosti- nos y las langostas. Algunas especies son particularmente llamativas por su forma y sus colores. El grupo de los crustáceos decápodos corresponde a una orden dentro del filo de los Arthropoda (Subfilo Crustacea: Orden Decapoda). Se caracteriza por tener un caparazón generalmente bien calcificado y (salvo algunas excepciones) 10 pares de “patas” (o pereiópodos) que sirven como apéndices prensiles o para desplazarse. Contiene unas 18000 especies y está formado por dos subórdenes y 10 infraordenes. El primer suborden, los Dendrobranchiata, corresponde, entre otras especies, a los camarones clásicos (e.g., los Penaeidae que se pescan en las costas de México). Los Pleocyemata, el segundo suborden de decápodos, contiene todas las demás especies de camarones, langostinos, langostas y cangrejos reparti- das entre 10 infraordenes (Stenopodidea, Caridea, Astacidea, Glypheidea, Axiidea, 1 Laboratorio de Invertebrados Bentónicos, Instituto de Ciencias del Mar y Limnología, Uni- dad Académica Mazatlán, Universidad Nacional Autónoma de México, Joel Montes Cama- rena s/n, Mazatlán 82040, Sinaloa, México.

De estos, ocho tienen representantes en aguas profundas (Martin y Davis 2001, Brusca y Brusca 2002). Los Glypheidae, con solamente dos especies vivas, no tienen representantes en aguas profundas.

  • 1 Amphipoda of the Northeast Pacific (Equator to Aleutians, Intertidal to Abyss): IX. Photoidea
    Amphipoda of the Northeast Pacific (Equator to Aleutians, intertidal to abyss): IX. Photoidea - a review Donald B. Cadien, LACSD 22 July 2004 (revised 21 May 2015) Preface The purpose of this review is to bring together information on all of the species reported to occur in the NEP fauna. It is not a straight path to the identification of your unknown animal. It is a resource guide to assist you in making the required identification in full knowledge of what the possibilities are. Never forget that there are other, as yet unreported species from the coverage area; some described, some new to science. The natural world is wonderfully diverse, and we have just scratched its surface. Introduction to the Photoidea Over more than a century the position of the photids has been in dispute. Their separation was recommended by Boeck (1871), a position maintained by Stebbing (1906). Others have relegated the photids to the synonymy of the isaeids, and taxa considered here as photids have been listed as members of the Family Isaeidae in most west coast literature (i.e. J. L. Barnard 1969a, Conlan 1983). J. L. Barnard further combined both families, along with the Aoridae, into an expanded Corophiidae. The cladistic examination of the corophioid amphipods by Myers and Lowry (2003) offered support to the separation of the photids from the isaeids, although the composition of the photids was not the same as viewed by Stebbing or other earlier authors. The cladistic analysis indicated the Isaeidae were a very small clade separated at superfamily level from the photids, the neomegamphopids, and the caprellids within the infraorder Caprellida.

Scientific review, however, does not constitute an endorsement of the Seafood Watch program or its recommendations on the part of the reviewing scientists. Seafood Watch is solely responsible for the conclusions reached in this report. We always welcome additional or updated data that can be used for the next revision. Seafood Watch and Seafood Reports are made possible through a grant from the David and Lucile Packard Foundation. 2 Final Seafood Recommendation Southern king crab (Lithodes santolla) from trap fisheries within Argentine waters is assessed as a Good Alternative.
