From the sea to aquafeed: A perspective overview

open access: yesReviews in Aquaculture, Volume 15, Issue 3, Page 1028-1057, June 2023., 2023
Abstract Aquaculture has been one of the fastest‐growing food production systems sectors for over three decades. With its growth, the demand for alternative, cheaper and high‐quality feed ingredients is also increasing. Innovation investments on providing new functional feed alternatives have yielded several viable alternative raw materials ...

Global Warming and the Spread of the Introduced Jellyfish Cassiopea andromeda: Thermal Niche and Habitat Suitability in the Mediterranean Sea. [PDF]

open access: yesGlob Chang Biol
Written Summary: Climate change is reshaping marine ecosystems, with the Mediterranean Sea among the most vulnerable due to warming and non‐native species such as the upside‐down jellyfish Cassiopea andromeda. We investigated the thermal tolerance and habitat suitability of its polyps, a key stage for reproduction and persistence.

Identification and Verification of the Blue Pigment in the Edible Jellyfish (Rhopilema esculentum)

open access: yesAquaculture Research, Volume 2023, Issue 1, 2023., 2023
Rhopilema esculentum is widely cultured in Chinese coastal regions and has thousand years of consumption history in China. Despite R. esculentum owns multiple colors (mainly ochre and blue) in aquaculture ponds, little is known about the pigments and color formation. This study identified and verified the blue pigment of R. esculentum.

Successful Culture of Pelagia noctiluca (Cnidaria: Scyphozoa) Over Time: A Continuous Supply of the Holoplanktonic Jellyfish for Research and Industrial Applications

open access: yesFrontiers in Marine Science, 2022
The scyphozoan Pelagia noctiluca has potential value for research and a wide variety of industrial applications. However, its holoplanktonic life cycle makes it difficult to maintain a permanent stock in aquaculture, unlike the continuous supply of newly-

Stable landings mask irreversible community reorganizations in an overexploited Mediterranean ecosystem

open access: yesJournal of Animal Ecology, Volume 91, Issue 12, Page 2465-2479, December 2022., 2022
Using novel methodology to investigate the presence of regime shifts in the Northern Adriatic Sea marine community, this work provides evidence of probably‐irreversible changes over the last 40 years connected to fishing pressure and climate change. Understanding these discontinuous dynamics is important in managing our oceans sustainably under climate

Circles in the sea: annual courtship “torus” behaviour of basking sharks Cetorhinus maximus identified in the eastern North Atlantic Ocean

open access: yesJournal of Fish Biology, Volume 101, Issue 5, Page 1160-1181, November 2022., 2022
Abstract Groups of basking sharks engaged in circling behaviour are rarely observed, and their function remains enigmatic in the absence of detailed observations. Here, underwater and aerial video recordings of multiple circling groups of basking sharks during late summer (August and September 2016–2021) in the eastern North Atlantic Ocean showed ...

Spawning site distribution of a bluefin tuna reduces jellyfish predation on early life stages

open access: yesLimnology and Oceanography, Volume 66, Issue 10, Page 3669-3681, October 2021., 2021
Abstract Bluefin tunas across the world migrate long distances to spawn in particularly warm and oligotrophic areas constrained by oceanographic fronts. The low abundance of predators in these areas increases survival chances of their early life stages, but its importance for choice of spawning habitat is unknown. Here, we use estimated clearance rates

The venom and the toxicity of Pelagia noctiluca (Cnidaria: Scyphozoa). A review of three decades of research in Italian laboratories and future perspectives

open access: yesJournal of Biological Research, 2015
Recurrent outbreaks of Pelagia noctiluca and health problems consequent to stings were recorded during the last decades. This phenomenon forced some Italian University laboratories to study this cnidarian.

Haemolytic activity and characterization of nematocyst venom from Pelagia noctiluca (Cnidaria: Scyphozoa) [PDF]

open access: yes, 2013
We investigated the haemolytic capacity of the crude venom extracted from isolated nematocysts of Pelagia noctiluca (Cnidaria: Scyphozoa), and evidenced the proteic fractions responsible for this activity.

Versatile aquarium for jellyfish: A rearing system for the biomass production of early life stages in flow-through or closed systems

open access: yesFrontiers in Marine Science, 2022
Interest in the rearing of jellyfish has grown exponentially over recent years due to their indisputable potential in a wide variety of uses and research. Here, we describe the design and operation of an effective modified kreisel aquarium that allows to
