Pacea, , Eric N. Powella, Roger Mannb a Gulf Coast Research Laboratory, University of Southern Mississippi, 703 East Beach Drive, Ocean Springs, MS 39564, United States b Virginia Institute of Marine Science, The College of William and Mary, Rt. 1208 Greate Road, Gloucester Point, VA 23062-1346, United States ARTICLE INFO ABSTRACT Keywords: Ocean quahogs [Arctica islandica (Linnaeus, 1769)] are the longest-lived, non-colonial animal known today, with Ocean quahog a maximum life span exceeding 500 years. Ocean quahogs are a commercially important bivalve, inhabiting the Arctica islandica continental shelf of the North Atlantic basin. We examined growth rates of ocean quahogs that were fully re- Growth cruited to the commercial fishery (> 80-mm shell length) from four sites covering the range of the stock along Little Ice Age the east coast of the U.S. through analysis of annual growth lines in the hinge plate. Both geographic and Climate change temporal differences (on a scale of decadal or longer) in growth rates exist throughout the range of the stock. The age at which animals reached 60, 80, and 90 mm decreased significantly, and average growth rates to 60, 80, and 90 mm increased significantly with birth year at a New Jersey and a Long Island site, both located in the southwestern portion of the stock, since the late 1700s/early 1800s, likely in response to increasing bottom water temperatures.

Koen-Alonso3, Mar Sacau Cuadrado4, Hannah Munro3 1Department of Fisheries and Oceans, Dartmouth, Nova Scotia, Canada. 2CEFAS, Lowestoft , Suffolk, United Kingdom. 3Department of Fisheries and Oceans, St. John’s, Newfoundland and Labrador, Canada. 4Institute of Spanish Oceanography, Vigo, Spain. Abstract In support of the 2021/2022 NAFO review of the closed areas to protect vulnerable marine ecosystems (VMEs) in the NAFO Regulatory Area, previously established kernel density estimation (KDE) methods were applied to four important ecological functions provided by benthic communities: A) Bioturbation; B) Nutrient cycling; C) Habitat provision; and D) Functional diversity (FRic), in order to evaluate significant adverse impacts of NAFO bottom-contact fishing on vulnerable marine ecosystems against the wider benthic contributions to those functions. Fish and invertebrate species recorded in the EU and Canadian surveys from 2011-2019 were classified a priori as contributing to each of bioturbation, nutrient cycling and habitat provision functions, using literature references. The resultant catch biomass data for each function were examined using K-S statistics and cumulative biomass distribution plots to determine whether data from the different surveys could be combined. With few exceptions the surveys were analyzed separately and the KDE polygons overlain a posteriori to produce combined polygon areas for each function. A suite of species were important contributors to the biomass of catches used to delineate each of the KDE polygons.

Tools will be implemented to monitor environmental parameters of the Arctic ecosystem at different time scales (from the daily to the decadal scales) by using two bivalves species, Chlamys islandica and Astarte spp., and at different spatial scales (from the single fjord to a pan-arctic view). Moreover, research in ecology will serve the visual and plastic design. This project will be the occasion for scientists and artists to work together around the climate change issues, transgressing the limits of each discipline. Keywords: Arctic bivalves; climate; growth; proxy; biology; marine ecology 2 PAN-ARCTIC BIVALVES AS POLAR BIOARCHIVES BIVALVES PAN-ARCTIQUES COMME BIOARCHIVES POLAIRES B.B. POLAR Context and issues: Research to calibrate Arctic bivalves as indicators of environmental variations has been underway for the last decade. In the Observatory at the European Institute of Marine Studies (IUEM), we have demonstrated since 1994 that the King scallop (Pecten maximus) provides exceptional biological archives of the temperate environment1.

  • Chlamys Varia (Bivalvia: Pectinidae)
    MARINE ECOLOGY PROGRESS SERIES Vol. 18: 253-262,1984 - Published August 15 Mar. Ecol. Prog. Ser. Energetic parameters of a population of Chlamys varia (Bivalvia: Pectinidae) M. S. Shafeel and G.Conan2 * Section Halieutique Institut Agronomique et Veterinaire Hassan 11, B.P.: 6202, Rabat-Instituts Rabat, Morocco Centre de Recherche en Biologic Marine, Universite de Moncton, Moncton, N. B. E1A 349, Canada ABSTRACT: Energy relations of a population of black scallop Chlamys varia (L.) in Lanveoc (Bay of Brest, France) were studied from 1976 to 1978. The population had a production of 538.52 Kcall00 mu' and of 497.10 Kcal 100 m"' during the years 1976 to 77 and 1977 to 78, respectively; it assimilated 5773.21 Kcal 100 m-' during the first year and 4561.21 Kcal 100 m"' during the second year of this study. Net production efficiency of black scallops (9 to 12 %) was very low compared to that of other bivalve populations reported so far. Average annual biomass of the population studied was 1252.59 Kcal 100 m-2 and 956.06 Kcal during the 2 yr period of study. Considerable energy was eliminated by the population due to mortality (natural and fishing mortality): 1017.42 Kcall00 m2and 939.51 Kcal 100 m2during the first and second second year, respectively. Average P:B ratios were 0.43 and 0.52 during the 2 yr. INTRODUCTION the period of this study (1976-1979) scallops were commericially fished every year 3 times a week from The black scallop Chlamys varia (L.), a pectinid October to March. lamellibranch, is common to Atlantic coasts of France The population studied was subtidal.
