  • Clearance Rates of Jellyfish and Their Potential Predation Impact on Zooplankton and Fish Larvae in a Neritic Ecosystem (Limfjorden, Denmark)
    MARINE ECOLOGY PROGRESS SERIES Vol. 304: 117–131, 2005 Published December 8 Mar Ecol Prog Ser Clearance rates of jellyfish and their potential predation impact on zooplankton and fish larvae in a neritic ecosystem (Limfjorden, Denmark) Lars Johan Hansson1,*, Ole Moeslund2, Thomas Kiørboe1, Hans Ulrik Riisgård2 1Danish Institute for Fisheries Research, Kavalergården 6, 2920 Charlottenlund, Denmark 2Marine Biological Research Centre (University of Southern Denmark) Hindsholmvej 11, 5300 Kerteminde, Denmark ABSTRACT: Clearance rates of the hydromedusae Sarsia tubulosa, Rathkea octopunctata and Bougainvillea superciliaris and the scyphomedusa Aurelia aurita were measured in the laboratory. Gut contents analyses of A. aurita were also collected in situ and subsequently used for estimation of clearance rate. The clearance rate of A. aurita varied widely with prey organisms. Large crustacean prey with low escape capabilities (Artemia salina nauplii and cirripede larvae) were cleared at high rates, whereas copepodites were cleared at lower rates, and clearance rates of small bivalve larvae and copepod nauplii were comparatively low. These data were used to assess the impact of jellyfish preda- tion upon zooplankton and fish larvae in Limfjorden, Denmark. Repeated sampling of zooplankton, fish larvae and medusae was undertaken during the first half of 2003. Nine taxa of hydromedusae and 4 taxa of scyphomedusae were identified. Abundance estimates were combined with estimated clear- ance rates of individual medusae to calculate potential jellyfish-induced mortality on prey in Limfjor- den. Copepoda was used as a model prey group to estimate the collective predation impact by all medusae. Medusa species with unknown clearance potential were given assumed clearance rate val- ues, but the collective predation potential by these species was evaluated to be small.

The seasonal abundance and distribution of the dominant species of hydromedusae along a salinity gradient within the Gironde Estuary, Atlantic coast of France, were evaluated based on monthly surveys, June 2013 to April 2014. The results confirmed the presence of three species considered to be introduced in many coastal ecosystems around the world: Nemopsis bachei (Agassiz, 1849), Blackfordia virginica (Mayer, 1910), and Maeotias marginata (Modeer, 1791). These species were found at salinities ranging from 0 to 22.9 and temperatures ranging from 14.5 to 26.6 ºC, demonstrating their tolerance to a wide range of estuarine environmental conditions.

ABSTRACT: Hydroids are common components of fouling communities in the sea, but they are often inconspicuous and easily overlooked. In such cases, the appearance of their medusae in plankton is an obvious indicator of the species’ presence in a locality. In this study, we present the first record of medusae Bougainvillia principis from the White Sea. We hypothesize that hydroids of the species B. principis inhabit the White Sea, as well, but they do not usually produce medusae and consequently the species does not exhibit sexual reproduction in the White Sea.

  • (Cnidaria, Hydrozoa) from the Madeira Archipelago
    On a collection of hydroids (Cnidaria, Hydrozoa) from the Madeira archipelago PETER WIRTZ Wirtz, P. 2007. On a collection of hydroids (Cnidaria, Hydrozoa) from the Madeira archipelago. Arquipélago. Life and Marine Sciences 24:11-16. Hydroids were collected from Madeira and Porto Santo Islands (eastern temperate Atlantic Ocean) by SCUBA diving over a depth range from 0 to 62 m, as well as by two trawls off the city of Funchal, at depths of 60 and 100 m. A preliminary list of 53 identified species from 33 genera and 17 families is given and comments are made on some of them. Eight of them could not be determined to species level because they either lacked gonophores or the medusa stage is necessary for identification. An undescribed species (genus Sertularella) will be described in a separate publication. Additional species have been sent to hydroid specialists, and their identifications are pending. Key words: hydrozoa, Madeira, Sertularella, species list Peter Wirtz (e-mail: [email protected]), Centro de Ciências do Mar, Universidade do Algarve, Campus de Gambelas, PT-8005-139 Faro, Portugal. INTRODUCTION Hydroid colonies were collected by SCUBA diving, at depths ranging from 0 to 62 m, and The Hydrozoa of Madeira were reported on as during two trawls off the city of Funchal, at early as the middle of the 19th century (Busk depths of 60 and 100 m.

  • CNIDARIA Corals, Medusae, Hydroids, Myxozoans
    FOUR Phylum CNIDARIA corals, medusae, hydroids, myxozoans STEPHEN D. CAIRNS, LISA-ANN GERSHWIN, FRED J. BROOK, PHILIP PUGH, ELLIOT W. Dawson, OscaR OcaÑA V., WILLEM VERvooRT, GARY WILLIAMS, JEANETTE E. Watson, DENNIS M. OPREsko, PETER SCHUCHERT, P. MICHAEL HINE, DENNIS P. GORDON, HAMISH J. CAMPBELL, ANTHONY J. WRIGHT, JUAN A. SÁNCHEZ, DAPHNE G. FAUTIN his ancient phylum of mostly marine organisms is best known for its contribution to geomorphological features, forming thousands of square Tkilometres of coral reefs in warm tropical waters. Their fossil remains contribute to some limestones. Cnidarians are also significant components of the plankton, where large medusae – popularly called jellyfish – and colonial forms like Portuguese man-of-war and stringy siphonophores prey on other organisms including small fish. Some of these species are justly feared by humans for their stings, which in some cases can be fatal. Certainly, most New Zealanders will have encountered cnidarians when rambling along beaches and fossicking in rock pools where sea anemones and diminutive bushy hydroids abound. In New Zealand’s fiords and in deeper water on seamounts, black corals and branching gorgonians can form veritable trees five metres high or more. In contrast, inland inhabitants of continental landmasses who have never, or rarely, seen an ocean or visited a seashore can hardly be impressed with the Cnidaria as a phylum – freshwater cnidarians are relatively few, restricted to tiny hydras, the branching hydroid Cordylophora, and rare medusae. Worldwide, there are about 10,000 described species, with perhaps half as many again undescribed. All cnidarians have nettle cells known as nematocysts (or cnidae – from the Greek, knide, a nettle), extraordinarily complex structures that are effectively invaginated coiled tubes within a cell.
