It promises to be a suitable finale to Series I, which has seen us visit all continents except Antarctica. Episode One kicked off in North America during January 2000, when Monty Graham and Jennifer Purcell invited us to Gulf Shores. Seven years later Kylie Pitt dragged us off to the Gold Coast in Australasia for episode Two, and our late, and much beloved, colleague Hermes Mianzan introduced us to the delights of a cold and wet Mar del Plata in South America some three years later. In 2013, Shin-Ichi Uye welcomed us to Asia by hosting episode Four in Hiroshima and Europe's turn came in 2016, when Verónica Fuentes and her team seduced us in a visit to Barcelona. Episode Six takes us to the cradle of humankind, thereby returning us to the polyp. Polyps can develop in a myriad of ways, and we have tried to emphasise development in our programme and associated events. A student at the Red and Yellow Creative School of Business has designed our logo, and a student jazz band from the University of the Western Cape (UWC) will provide our entertainment at the gala dinner. We have deliberately collaborated with the Creative Design Institute to provide local entrepreneurs with an opportunity to develop conference-themed items for retail, and we encourage you to both support their imagination and spread the word. Our conference bags, generously sponsored by De Beers, are made by local communities using locally sourced, in part recycled, materials: if you have purchased a T-shirt, it too is manufactured locally using locally sourced recycled plastics. Our organisational partners are Iziko Museums of South Africa and the Two Oceans Aquarium, and both organisations have capitalised on the meeting in various outreach activities with the broader public. Spreading our science beyond the academy is important in a developing country like ours, and we would urge future meetings to engage similarly with their communities. 6TH INTERNATIONAL JELLYFISH BLOOMS SYMPOSIUM 1 CAPE TOWN, SOUTH AFRICA | 4 - 6 NOVEMBER 2019 ME But we are here for the science, and the science programme is a packed one, with almost 150 presentations delivered by participants from 25 SS countries and all continents, except Antarctica. We have representatives from six African countries, thanks to generous help from the South African A National Research Foundation. We are especially pleased to see so many GE FR students (almost 50) and we are grateful to all the PIs that have had to make sacrifices in order to allow their mentees to participate. OM THE C In Barcelona, when Monty Graham twisted my arm to agree to host the sixth meeting, I implied that lions walked the streets of the city – this is Africa after all! I am sorry but I lied, and the last lion seen wandering around Cape Town was shot in 1802: though leopards are regularly seen not 60 km away. Although I didn't lie about the uncertainty and chaos that we are facing in the world today, I am hoping that you will forget about it ONVENOR for the next three days and immerse yourselves in the science of jellyfish and the people that share your passion. And of course, that you will find the time to, carefully, enjoy the splendour and serenity of Cape Town. Welcome. 6TH INTERNATIONAL JELLYFISH BLOOMS SYMPOSIUM 2 CAPE TOWN, SOUTH AFRICA | 4 - 6 NOVEMBER 2019 The southern tip of the African continent is the meeting place of two mighty and bountiful oceans, the Indian and the Atlantic. The Two Oceans Aquarium on the V&A Waterfront, Cape Town is ideally positioned to showcase the incredible diversity of marine life found in these two oceans. The Aquarium's exhibits and displays have an educational focus, providing access to this unique natural world to more than 500 000 visitors per year, from near and far. In addition to being an award-winning attraction, the Aquarium is also deeply invested in environmental education and campaigning, conservation, and research. In 2018 the Two Oceans Aquarium Education Foundation was established as a registered Non-Profit Organisation with Public Benefit status, making possible the expansion of its education, conservation and research programmes. We welcome the International Jellyfish Blooms community to Cape Town and the Two Oceans Aquarium, and we wish you a successful, informative, productive and enjoyable symposium.

UWC was established in 1959 in terms of the extension of Higher Educaon Act of 1956 as a University College for “non-whites other than Bantu”. Rejecng these ideological foundaons, it became the home of the an-apartheid le and a large part of the leadership of the new South Africa originated from UWC. Relevant research from the University informed early policy development and the University connues to be at the forefront of intellectual debate and transion, producing new generaons of researchers and graduates to provide leadership for their communies, and their world. In the face of global climate change, poverty, inequality and the clash of cultures, UWC sees itself as an engaged university - a nexus of research, teaching and learning that responds to the needs of a society in transion in crical and creave ways. The University is commied to being a research-led learning-focused university that acts as an anchor instuon in the region, connecng communies, industries and academics: it strives to be a hub in the research and innovaon landscape as well as a place with a sense of community, where collecve leadership maers. Drawing on its proud experience in the liberaon struggle, the www.uwc.ac.za University is commied to a disncve academic role in helping to build an equitable and dynamic society. 6TH INTERNATIONAL JELLYFISH BLOOMS SYMPOSIUM 4 CAPE TOWN, SOUTH AFRICA | 4 - 6 NOVEMBER 2019 6TH INTERNATIONAL JELLYFISH BLOOMS SYMPOSIUM 5 CAPE TOWN, SOUTH AFRICA | 4 - 6 NOVEMBER 2019 Sunday 3 November 2019 OPENING CEREMONY OPENING CEREMONY TWO OCEANS AQUARIUM DOCK ROAD AT THE V&A WATERFRONT 18:30 Registraon of parcipants, collecon of the conference bags, and the conference T-shirts will be located next to Nemos' tank, follow the posted signs.

Marine Biodiversity Records (2016) 9:21 DOI 10.1186/s41200-016-0023-8 MARINE RECORD Open Access An observation of two oceanic salp swarms in the Tasman Sea: Thetys vagina and Cyclosalpa affinis Natasha Henschke1,2,3*, Jason D. Everett1,2,3 and Iain M. Suthers1,2,3 Abstract Background: Large oceanic salps are rarely encountered. The highest recorded biomasses of the salps Thetys vagina (852 g WW m−3)andCyclosalpa affinis (1149 g WW m−3) were observed in the Tasman Sea during January 2009. Results: Due to their fast sinking rates the carcasses and faecal pellets of these and other large salps play a significant role in carbon transport to the seafloor. We calculated that faecal pellets from these swarms could have contributed up to 67 % of the mean organic daily carbon flux in the area. This suggests that the flux of carbon from salp swarms are not accurately captured in current estimates. Conclusion: This study contributes information on salp abundance and biomass to a relatively understudied field, improving estimates for biogeochemical cycles.

  • Medusa Catostylus Tagi: (I) Preliminary Studies on Morphology, Chemical Composition, Bioluminescence and Antioxidant Activity
    MEDUSA CATOSTYLUS TAGI: (I) PRELIMINARY STUDIES ON MORPHOLOGY, CHEMICAL COMPOSITION, BIOLUMINESCENCE AND ANTIOXIDANT ACTIVITY Ana Maria PINTÃO, Inês Matos COSTA, José Carlos GOUVEIA, Ana Rita MADEIRA, Zilda Braga MORAIS Centro de Polímeros Biomédicos, Cooperativa Egas Moniz, Campus Universitário Quinta da Granja, 2829-511, Portugal, [email protected] The Portuguese continental coast, specially Tejo and Sado estuaries, is the habitat of Catostylus tagi [1]. This barely studied medusa was first described in 1869, by Haeckel, and is classified in the Cnidaria phylum, Scyphozoa class, Rhizostomeae order, Catostylidae family, Catostylus genus. According to the European Register of Marine Species, the referred medusa is the only species of the Catostylidae family found in the European continent [2]. C. tagi is particularly abundant during the summer. Several medusas from the Rhizostomae order are traditionally used as food in some oriental countries [3]. Simultaneously, modern medusa utilizations are related to bioluminescence [4], toxicology [5] and biopolymers [6]. The lack of information on this genus along with the recent discoveries of new marine molecules showing anti-arthritic, anti-inflammatory or antioxidant properties motivated our studies [7]. In addition, the abundant medusa biomass could be evaluated as another natural collagen source, alternative to bovine collagen, with its multiple cosmetic and surgical potential uses [8]. The capture and sample preparation methods were optimized in 2003 [9]. Results reported in this poster relate to 65 animals that were captured in the river Sado in August and September of 2004. Macroscopic aspects, like mass and dimensions, were evaluated as well as their C. tagi by J.Gouveia chemical characteristics.

To address this knowledge gap, we provide a holistic trophic characterization of a jelly web in the eastern tropical Atlantic, based on δ13C and δ15N stable isotope analysis of a unique gelatinous zooplankton sample set. The jelly web covered most of the isotopic niche space of the entire planktonic oceanic food web, spanning > 3 tro- phic levels, ranging from herbivores (e.g., pyrosomes) to higher predators (e.g., ctenophores), highlighting the diverse functional roles and broad possible food web relevance of gelatinous zooplankton.

    The secret lives of JELLYFISH Long regarded as minor players in ocean ecology, jellyfish are actually important parts of the marine food web.

The marine biologist sports a rain suit, calories than some which seems odd for a sunny day in August until the bottom of the net other jellyfish. is manoeuvred in her direction, its mesh straining from a load of moon jellyfish (Aurelia aurita). Slime drips from the bulging net, and long ten- tacles dangle like a scene from an alien horror film.

    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.
