Résumé traduit : Les résultats de cette étude sont encourageants et fournissent les moyens vers un moyen efficace de surveiller les méduses, qui peut être utilisé pour le développement d'un système d'alerte précoce des méduses, fournissant des informations très précieuses pour les biologistes marins et contribuant à la réduction des impacts des méduses sur humains – guatemalt
Monitoring these changes in a cost-effective manner is of high relevance to assess the environmental status and evaluate the effectiveness of management measures.
In particular, recent studies point to a rise of jellyfish populations on a global scale, negatively affecting diverse marine sectors like commercial fishing or the tourism industry. Past monitoring efforts using underwater video observations tended to be time-consuming and costly due to human-based data processing.

Résumé traduit : L'étude a révélé que seule une seule espèce de méduse rhizostomatidée, Crambionella annandalei, soutient la pêche active des méduses. La saison de pêche s'est déroulée de mars à juillet. Bien que la pêche aux méduses ait entraîné des avantages économiques substantiels pour les pêcheurs, les transformateurs et donc l'économie locale, elle pourrait avoir un impact négatif sur les populations de méduses de la région. Les bras oraux transformés de la méduse ont une bonne demande et sont exportés vers les pays d'Asie du Sud-Est, principalement la Chine. Les procédures détaillées impliquées dans le traitement des méduses sont également discutées dans cet article. – guatemalt
MARINE BIODIVERSITY RECORDS 02/05/19 Distribution of the highly toxic clinging jellyfish Gonionemus sp. around the island of Martha’s Vineyard, Massachusetts, USA. Gonionemus sp. medusae were found in five coastal ponds distributed around the island.
Medusae had been previously reported from four of these (Farm Pond, Sengekontacket Pond, Stonewall Pond, and Lake Tashmoo; Govindarajan and Carman 2016). This is the first record of Gonionemus sp. medusae in Edgartown Great Pond. It is likely that this represents a recent range expansion, as the Great Pond Foundation and Edgartown Shellfish Department have monitored the pond for decades (Reddington 2018; Howes et al. 2008) and would almost certainly have been observed it if it were present.
Medusae were not found in Squibnocket Pond, although they had been reported there previously (Govindarajan and Carman 2016). Squibnocket Pond ranges in salinity from fresh to brackish depending on the location within the pond and the presence of salt water over-wash (Howes et al. 2017). Gonionemus sp. medusae were only found at sites with eelgrass. Food Quality and Preference Volume 79, January 2020, The attitudes of Italian consumers towards jellyfish as novel food.
Introduction Scientific research and reports of inter-governmental organizations jointly point out the need of changing global food consumption patterns to foster sustainable consumer behavior and achievement of biodiversity conservation goals (Robins, 1999; European Commission, 2008, FAO, 2008, United Nations Educational, Scientific and Cultural Organization, UNESCO, 2010, FAO, 2017). Shared recommendations advocate consumption of local, low-industrialized and renewable food products (FAO, 2011) increasing the awareness that consumers’ food choices represent significant environmental decisions.
Recently, regarding seafood products the FAO fishery guidelines focused on “eco-labelled fish products” (FAO, 2018) to enhance sustainable seafood production and environmental protection to mitigate impacts of sudden climatic change and biotic modifications. Ecological Society of America - 2014 - Linking human well-being and jellyfish: ecosystem services, impacts, and societal responses.

Fuentes1,*, Jennifer E. BIOLOGICAL REVIEWS 14/02/18 Evolution and development of scyphozoan jellyfish. Scyphozoans (Cnidaria) are abundant and important members of many ocean habitats, and their most obvious ecological impact is related to the final life‐cycle stage: the jellyfish.
This jellyfish stage, termed a ‘scyphomedusa’ or ‘medusa’, is the most recognizable scyphozoan form, but it is far from the only one. Scyphozoan life cycles are among the most complex of any non‐parasitic animal, with different life‐cycle stages inhabiting different ecosystems and varying in size by orders of magnitude. These complex life cycles provide a unique opportunity to study life‐cycle evolution, the role of development in the evolution of novel life histories, and the dynamics between development and the environment. In most scyphozoans, the life cycle is broken into three stages. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 31/01/18 Eating jellyfish: safety, chemical and sensory properties.

Helgoland Marine Research 01/08/18 First record of the non-indigenous jellyfish Blackfordia virginica (Mayer, 1910) in the Baltic Sea. We describe the first record of the hydromedusan jellyfish Blackfordia virginica from northern Europe, namely Kiel Canal and Kiel Fjord, southwestern Baltic Sea.
So far, standardised sampling of gelatinous zooplankton in other parts of the Baltic Sea has not detected the species during the past 10 years. The persistent presence of medusae populations during summer/autumn and seasonal variation in their size distribution in Kiel Canal indicate active recruitment throughout summer since 2016. Concerning the question of the initial introduction vector to the Kiel Canal, there is no direct evidence.
Shipping has been suggested to be the major cause for the primary introduction of non-indigenous species in the marine realm, both due to ballast water release and from fouling communities on ship hulls . No ballast water release takes place in Kiel Canal and the water exchange with the North Sea and Baltic Sea is limited. We further confirm B. virginica from Kiel Bight.

Contributed by: European Science Foundation ESF participates in European research project on the use of jellyfish blooms as solutions for producing new products. While some people might find these slimy creatures at the beach very exciting, a number of species are poisonous; some tropical species are even among the most toxic animals on earth.
Even worse, rising water temperatures, ocean acidification and overfishing seem to favor the jellyfish blooms. More and more often, they appear in huge swarms, which have already destroyed whole fish farms on European coasts and blocked cooling systems of power stations near the coast. Can we find a solution to this emerging environmental threat? A consortium of 15 scientific institutions from eight countries coordinated by the GEOMAR Helmholtz Centre for Ocean Research Kiel has an innovative idea. In the GoJelly project, funded by the European Union with six million euros over a four-year period, they want to sensibly use this perceived threat. First, there is still basic work to do for all partners. Jellyfish can also be used as fertilizers for agriculture or aquaculture feeds. PARLEMENT EUROPEEN - Réponse à question E-007083/2017 Measures to resolve the Pelagia Noctiluca jellyfish problem. During the summer of 2017, the Gulf of Corinth and the Gulf of Patras were infested with blooms of Pelagia Noctiluca jellyfish, causing major problems for tourism, one of the main sources of income for their coastal resorts, making it impossible to go bathing and driving visitors elsewhere.
It is estimated that seaside establishments in Loutraki, for example, suffered a possible 70%, fall in business turnover generated by domestic tourism. This has caused significant losses to all areas washed by the Gulf of Corinth, or will do so if immediate measures are not taken, given the unexpected proportions assumed by this problem over the last four or five years. It is essential to take immediate action to tackle the problem if the economic survival of local residents is to be assured in view of the approaching 2018 summer season. Any such measures must be taken without delay if they are to have any effect. Front Ecol Environ 2013; 11(2): 91–97, Is global ocean sprawl a cause of jellyfish blooms?

Introduction Interest in jellyfish grew considerably in recent years as a result of “anomalous” proliferations seen with increasing frequency in all seas and the new appearance of invasive species in temperate seas , linked to multiple causes such as climate change, overfishing and pollution [2,3,4]. Variations in temperature and salinity have been linked to variations in jellyfish abundance in a number of studies [5,6,7,8]. There is widespread concern that the oceans may increasingly be dominated by jellyfish, because many of them are able to increase in abundance rapidly and adapt to new conditions following ecosystem regime shifts . THE GUARDIAN 08/08/14 New jellyfish discovered: giant venomous species found off Australia. A giant and extremely venomous jellyfish found off Western Australia’s north-west coast has researchers stumped because it appears to have no tentacles.

PLOS 07/04/11 Gill Damage to Atlantic Salmon (Salmo salar) Caused by the Common Jellyfish (Aurelia aurita) under Experimental Ch. Background Over recent decades jellyfish have caused fish kill events and recurrent gill problems in marine-farmed salmonids.
Common jellyfish (Aurelia spp.) are among the most cosmopolitan jellyfish species in the oceans, with populations increasing in many coastal areas. The negative interaction between jellyfish and fish in aquaculture remains a poorly studied area of science. Thus, a recent fish mortality event in Ireland, involving Aurelia aurita, spurred an investigation into the effects of this jellyfish on marine-farmed salmon. Methodology/Principal Findings To address the in vivo impact of the common jellyfish (A. aurita) on salmonids, we exposed Atlantic salmon (Salmo salar) smolts to macerated A. aurita for 10 hrs under experimental challenge. Conclusions Our findings clearly demonstrate that A. aurita can cause severe gill problems in marine-farmed fish.
