  • Seasonal Variation in the Occurrence of Planktic Bivalve Larvae in the Schleswig-Holstein Wadden Sea
    HELGOLdkNDER MEERESUNTERSUCHUNGEN Helgolander Meeresunters. 51, 23-39 {1997} Seasonal variation in the occurrence of planktic bivalve larvae in the Schleswig-Holstein Wadden Sea Andrea Pulfrich* Institut ffir Meereskunde; Dfisternbrooker Weg 20, 24105 Kiel, Germany ABSTRACT: In the late 1980s, recruitment failures of the mussel Mytilus edulis led to economic pro- blems in the mussel fishing and cultivation industries of northwestern Europe. As part of a collabo- rative study to gain a better understanding of the mechanisms affecting recruitment processes of mussels, plankton samples were collected regularly over a four-year period (t990-I993) from three stations in the Schleswig-Holstein Wadden Sea. The bivalve component of the plankton was domi- nated by the Solenidae, which was almost exclusively represented by Ensis americanus [= directus). NI. eduhs was the second most abundant species. Abundances of mussel larvae peaked 2 to 4 weeks after spawning maxima in the adult populations. Although variations in timing and amplitude of the tota~ [arvaL densities occurred, annua[ abuadances o[M. edulis larvae remained stable during the study period, and regional abundance differences were insignificant. A close relaUonsh~p was found between peaks in larval abundance and phytoplankton blooms. Differences in larval concentrations in the ebb and the flow currents were insignificant. Planktic mussel larvae measured between 200 }am and 300 ~tm, and successive cohorts were recognizable in the majority of samples. Most lar- vae were found to originate from local stocks, although imports from outside the area do occur. INTRODUCTION Successive years of failing spatfall and recruitment of the edible mussel Mytilus edu- lis L. (Bivalvia) on the northwestern European coast during the late 1980s caused sub- stantial production Losses in the mussel fishing and cultivation industries.

Initially it was found only in Corio Bay, but during the past fiveyears it has spread so that it now occurs throughout the western half of Port Phillip Bay. • Densities of Sabella in many parts of the bay remain low but densities are usually higher (up to 13/m2 ) in deeper water and they extend into shallower depths in calmer regions. • Sabella larvae probably require a 'hard' surface (shell fragment, rock, seaweed, mollusc or sea squirt) for initial attachment, but subsequently they may use their own tube as an anchor in soft sediment . • Changes to fish communities following the establishment of Sabella were analysed using multidimensional scaling and BACI (Before, After, Control, Impact) design analyses of variance.

  • Processing of 13C-Labelled Phytoplankton in a Fine-Grained Sandy-Shelf Sediment (North Sea): Relative Importance of Different Macrofauna Species
    MARINE ECOLOGY PROGRESS SERIES Vol. 297: 61–70, 2005 Published August 1 Mar Ecol Prog Ser Processing of 13C-labelled phytoplankton in a fine-grained sandy-shelf sediment (North Sea): relative importance of different macrofauna species Anja Kamp1, 2,*, Ursula Witte1, 3 1Max Planck Institute for Marine Microbiology, Celsiusstr. 1, 28359 Bremen, Germany 2Present address: Institute for Microbiology, University of Hannover, Schneiderberg 50, 30167 Hannover, Germany 3Present address: Oceanlab, University of Aberdeen, Newburgh, Aberdeen AB41 6AA, UK ABSTRACT: On-board and in situ experiments with 13C-labelled diatoms were carried out to inves- tigate the processing of algal carbon by the macrofauna community of a fine sandy-shelf site in the southern German Bight (North Sea). The time series (12, 30, 32 and 132 h incubations) was supple- mented by additional laboratory experiments on the role of the dominant macrofauna organism, the bivalve Fabulina fabula (Bivalvia: Tellinidae), for particulate organic matter subduction to deeper sediment layers. The specific uptake of algal 13C by macrofauna organisms was visible after 12 h and constantly increased during the incubation periods. F. fabula, a facultative (surface) deposit- and suspension-feeder, Lanice conchilega (Polychaeta: Terebellidae), a suspension-feeder and the (sur- face) deposit-feeder Echinocardium cordatum (Echinodermata: Spatangidae) were responsible for the majority of macrofaunal carbon processing. Predatory macrofauna organisms like Nephtys spp. (Polychaeta: Nephtyidae) also quickly became labelled. The rapid subduction of fresh organic matter by F. fabula down to ca. 4 to 7 cm sediment depth could be demonstrated, and it is suggested that entrainment by macrofauna in this fine-grained sand is much more efficient than advective transport.

  • Population Dynamics of the Freshwater Clam Galatea Paradoxa from the Volta River, Ghana
    Knowledge and Management of Aquatic Ecosystems (2012) 405, 09 http://www.kmae-journal.org c ONEMA, 2012 DOI: 10.1051/kmae/2012017 Population dynamics of the freshwater clam Galatea paradoxa from the Volta River, Ghana D. Adjei-Boateng(1),,J.G.Wilson(2) Received February 6, 2012 Revised April 25, 2012 Accepted May 7, 2012 ABSTRACT Key-words: Population parameters such as asymptotic (L∞), growth coefficient (K), recruitment, mortality rates (Z, F and M), exploitation level (E) and recruitment pattern mortality, of the freshwater clam Galatea paradoxa were estimated using length- growth frequency data from the Volta River estuary, Ghana. The L∞ for G. para- parameters, doxa at the Volta estuary was 105.7 mm, the growth coefficient (K)and Volta River, the growth performance index (Ø)´ ranged between 0.14–0.18 year−1 and Bivalvia 3.108–3.192, respectively. Total mortality (Z) was 0.65–0.82 year−1, while natural mortality (M) and fishing mortality (F) were 0.35–0.44 year−1 and 0.21–0.47 year−1, respectively, with an exploitation level of 0.32–0.57. The recruitment pattern suggested that G. paradoxa has year-round recruit- ment with a single pulse over an extended period (October–March) in the Volta River. The Volta River stock of G. paradoxa is overfished and requires immediate action to conserve it. This can be achieved by implementing a minimum landing size restriction and intensifying the culture of smaller clams which is a traditional activity at the estuary.

    DISTRIBUTION, ABUNDANCE, AND DIVERSITY OF EPIFAUNAL BENTHIC ORGANISMS IN ALITAK AND UGAK BAYS, KODIAK ISLAND, ALASKA by Howard M. Feder and Stephen C. Jewett Institute of Marine Science University of Alaska Fairbanks, Alaska 99701 Final Report Outer Continental Shelf Environmental Assessment Program Research Unit 517 October 1977 279 We thank the following for assistance during this study: the crew of the MV Big Valley; Pete Jackson and James Blackburn of the Alaska Department of Fish and Game, Kodiak, for their assistance in a cooperative benthic trawl study; and University of Alaska Institute of Marine Science personnel Rosemary Hobson for assistance in data processing, Max Hoberg for shipboard assistance, and Nora Foster for taxonomic assistance. This study was funded by the Bureau of Land Management, Department of the Interior, through an interagency agreement with the National Oceanic and Atmospheric Administration, Department of Commerce, as part of the Alaska Outer Continental Shelf Environment Assessment Program (OCSEAP). SUMMARY OF OBJECTIVES, CONCLUSIONS, AND IMPLICATIONS WITH RESPECT TO OCS OIL AND GAS DEVELOPMENT Little is known about the biology of the invertebrate components of the shallow, nearshore benthos of the bays of Kodiak Island, and yet these components may be the ones most significantly affected by the impact of oil derived from offshore petroleum operations. Baseline information on species composition is essential before industrial activities take place in waters adjacent to Kodiak Island. It was the intent of this investigation to collect information on the composition, distribution, and biology of the epifaunal invertebrate components of two bays of Kodiak Island. The specific objectives of this study were: 1) A qualitative inventory of dominant benthic invertebrate epifaunal species within two study sites (Alitak and Ugak bays).

  • Molluscs: Bivalvia Laura A
    I Molluscs: Bivalvia Laura A. Brink The bivalves (also known as lamellibranchs or pelecypods) include such groups as the clams, mussels, scallops, and oysters. The class Bivalvia is one of the largest groups of invertebrates on the Pacific Northwest coast, with well over 150 species encompassing nine orders and 42 families (Table 1).Despite the fact that this class of mollusc is well represented in the Pacific Northwest, the larvae of only a few species have been identified and described in the scientific literature. The larvae of only 15 of the more common bivalves are described in this chapter. Six of these are introductions from the East Coast. There has been quite a bit of work aimed at rearing West Coast bivalve larvae in the lab, but this has lead to few larval descriptions. Reproduction and Development Most marine bivalves, like many marine invertebrates, are broadcast spawners (e.g., Crassostrea gigas, Macoma balthica, and Mya arenaria,); the males expel sperm into the seawater while females expel their eggs (Fig. 1).Fertilization of an egg by a sperm occurs within the water column. In some species, fertilization occurs within the female, with the zygotes then text continues on page 134 Fig. I.
