Jellyfish as an alternative source of food for opportunistic fishes 5
Marques, Raquel; Bouvier, Corinne; Darnaude, Audrey M.; Molinero, Juan-carlos; Przybyla, Cyrille; Soriano, Solenn; Tomasini, Jean-antoine; Bonnet, Delphine.
Although scientific interest on jellyfish ecology has substantially increased in the last decades, little is known on the role of potential predators shaping their population dynamics. Jellyfish were long considered as ‘dead ends’ within food webs, and therefore overlooked as potential food source for higher trophic levels, e.g. fishes. Here this question is tackled by using comprehensive laboratory experiments assessing fish predation on jellyfish. The approach included all the life stages (polyps, ephyrae and medusa) of Aurelia sp. versus more traditional aquaculture feeds in an easily farmed opportunistic fish, the gilthead seabream Sparus aurata (L.). Results revealed that all life stages of Aurelia sp. were accepted as a source of food by S. aurata,...

Dynamics and asexual reproduction of the jellyfish Aurelia coerulea benthic life stage in the Thau lagoon (northwestern Mediterranean) 5
Marques, Raquel; Darnaude, Audrey M.; Schiariti, Agustin; Tremblay, Yann; Molinero, Juan-carlos; Soriano, Solenn; Hatey, Elise; Colantoni, Sébastien; Bonnet, Delphine.
For many jellyfish, the magnitude and timing of medusae blooms are recognized to result from the benthic stage dynamics. However, information on the scyphistomae of jellyfish populations in the wild remains scarce. Here, bi-mensual underwater photoquadrat surveys were combined with scyphistomae sampling and observation to describe the annual (February 2017–January 2018) benthic stage dynamics and asexual reproduction strategy of Aurelia coerulea in the Thau lagoon (43°25′31.1″N; 03°42′0.9″E). Our results revealed unexpected seasonal patterns of variation: scyphistoma coverage peaked in the spring (11.6 ± 3.7% on 21st April) and was minimal in the summer and autumn (1.4 ± 1.3% on 10th October). The increase in scyphistoma coverage mainly resulted from an...

Déterminisme du recrutement larvaire de l’huître creuse (Crassostrea gigas) dans la lagune de Thau. 5
Lagarde, Franck; Fiandrino, Annie; Richard, Marion; Bernard, Ismael; Mortreux, Serge; Ubertini, Martin; Chiantella, Claude; Boj, Marie; Meddah, Slem; Leurion, Axel; Soriano, Solenn; Fuhrmann, Marine; Le Gall, Patrik; Chiera, Caroline; Berteaux, Tom; Guillou, Jean-louis; Roque D'Orbcastel, Emmanuelle; Perignon, Adeline; Bonnet, Delphine; Roques, Cecile; Bec, Beatrice; Cochet, Helene; Gervasoni, Erika; Miron, Gilles; Pouvreau, Stephane.
Since spat mortality events that were firstly detected in 2008, Mediterranean shellfish industry seeks to exploit the Pacific oyster spat from lagoon natural recruitment. The CRCM, Cepralmar and Ifremer developed accordingly a research project named PRONAMED Phase 1 and 2 - 2010-2014, in order to define the economic potential of spatfall and improve knowledge of the reproductive cycle of Crassostrea gigas in this specific environmental context. The results of the past three year‘s study (2012, 2013, 2014) showed that broodstock have the ability to provide larvae after sexual maturation and spawning. A coincidence was noted between moon phase (new and full moon) and spawnings with an amplifying effect of storms on the intensity of spawning (Ubertini et al....
