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. -

D. McIntyre and A. ~leftheriou Marine Laboratory, .berdeen. Introduction During 1965 the macrofauna of a sandy bay in a Scottish sea loqh was investigated. The work formed part of an extensive study by a larger group, of food chains leading to place, involving sarnpling of all trophic levels, combined with experimental work. The area investigated is Firemore, a sandy bay inside Loch Ewe (latitude 57°49t'N, 542'W). -
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. -

GES • Since the 1990s, various european Directives aimed at nature protection have been issued. The most recent is the « Marine Strategy » Framework Directive – « MSFD » • The MSFD targets reaching a GES in European seas. Targets are defined for 11 different descriptors of the marine ecosystem, including « seafloor integrity ». – “Sea-floor integrity is at a level that ensures that the structure and functions of the ecosystems are safeguarded and benthic ecosystems, in particular, are not adversely affected.” • This directive and others involves the definition of objective criteria towards measurement of the GES • The measurement of the amplitude of change induced by human pressures is necessary to set meaningful targets => Baseline assessment => Benthos composition = sensitive indicator for change in the seafloor condition => Monitoring Human Footprint on the Seafloor Brussel - RBINS 2/9/2011 Belgium: a unique historical macrobenthic data set: The surveys and material of G.
