“…One of the ocean regions most poorly studied in terms of jellyfish ecological data is the Southwestern Atlantic (SWA) [12,13]. There, the knowledge of species composition and distribution is characterized by a noticeable space-time discontinuity [14,15], and studies focused on jellyfish abundance in the area are practically nonexistent in spite of some efforts that have been made (see [16] for a review).…”

Gelatinous organisms are crucial components of marine ecosystems and some species imply social and economic consequences. However, certain geographic areas, such as the temperate Southwestern Atlantic (SWA, 27° - 56° S), remain understudied in terms of jellyfish ecological data. We analyzed 3,727 plankton samples collected along ~6.7 million km 2 over a 31-year period (1983–2014) to determine the occurrence, abundance, and diversity patterns of hydromedusae in the SWA. Analyses were made at both community and species levels. Two abundance hot spots of hydromedusae were identified, where values up to 2,480 ind. m -3 were recorded between 2003 and 2014. Liriope tetraphylla and Obelia spp. were the main responsible for recurrent peaks. Diversity indexes were in the range of those published for temperate areas worldwide, and some coastal zones showed values that can be considered moderate to high for a temperate neritic region. The community analysis yielded 10 groups following previously determined biogeographic schemes throughout the study area. This work enhances the knowledge of hydromedusae in the SWA and provides essential information about the current global warming context and the gelatinous zooplankton data necessity.

“…Additionally, in some species, embryos can develop directly into young medusae, as is the case for Pelagia noctiluca (exclusively) and, under rarer circumstances, for A. aurita. 13,36,45 Scyphozoan polyps (ie scyphistomae) are typically small sessile organisms (1-2 mm diameter and 1-3 mm tall, depending on the species) that have an oral disc (central mouth) with up to 24 tentacles (with cnidocytes) around the margin and present columnar bodies (with or without a tube encasing the aboral stalk) that attaches to a hard substrate at the aboral disc. Polyps are colonial organisms that can reproduce asexually to form new clonal polyps, through budding and podocyst formation (in some species), and new ephyrae, through strobilation (ie transverse fission followed by metamorphosis and production of free-swimming ephyrae) 4,[45][46][47] (Figure 1).…”

“…19,20,27,[77][78][79] More recently, interest in edible jellyfish fisheries has also extended to other locations, such as in the Western Hemisphere, often as a consequence of local collapses of more traditional fishery resources (eg finfish and shrimp). 13,14,26,[80][81][82] Catches of edible jellyfish have significantly increased worldwide, with at least 19 nations currently being involved in commercial fisheries targeting these organisms. 12,14,80,81 The global production of edible jellyfish products (live, fresh, chilled, frozen, dried, salted or in brine) was estimated to be around 10,000-17,000 tons/year between 2011 and 2015, representing a growing business trend of 20-100 million USD.…”

“…11,12 Similar constraints can also be caused by jellyfish on other important economic activities, such as those using industrial facilities requiring seawater to cool-down heavy machinery (eg by clogging water inflows of cooling systems), aquaculture (eg mass mortality in caged fish farmed and structural damage to aquaculture facilities by net fouling organisms) and tourism (eg stinging swimmers and raising the need to temporarily evacuate beaches). 1,[11][12][13] Overall, jellyfish are more often than desired in the 'spotlight' due to the negative impacts associated with their blooms, being commonly perceived as a nuisance or 'pest' organisms. 1,9,12,14 Curiously, jellyfish blooms worldwide have also sparked the attention of researchers, 12,15,16 due to the potential valorisation of their biomass for multiple uses.…”

Interest on jellyfish research has significantly increased over the last two decades, mostly driven by the potential benefits of their high-end uses. Recent efforts have been put forward towards the commercial use of scyphozoan jellyfish, although the pipeline leading to their full exploitation is still at an early stage of development.Indeed, further research and several technical advances are still required to expand the use of these bioresources to a larger and more sustainable scale. Here, we describe the state of the art of culture systems already available to farm these organisms throughout the different stages of their life cycle and provide an overview of the potential applications of jellyfish aquaculture for food, feed, as source of bioactive compounds for pharmaceutical and other biotechnological applications, as well as to supply the marine aquarium trade. Overall, this work aims to raise awareness on the relevance that jellyfish will likely play on the development of sustainable blue bioeconomy frameworks fostering a sustainable valorisation of marine living resources.

“…In the study area, ctenophore aggregations (mainly Mnemiopsis leidyi ) seem to coincide with hake reproductive peaks (Schiariti et al., 2018). Feeding by these ctenophores may diminish the nutritional condition of hake larvae through competition for food and, ctenophores could also prey on hake eggs and larvae as well (Purcell & Arai, 2001).…”

Variability in fish recruitment is a consequence of various processes that operate at different spatial and temporal scales. To understand this variability, it is necessary to study the factors that determine the survival of the early developmental stages of fish. These factors can be both physical and trophodynamic and act throughout the pre-recruit life of fish (Houde, 2008). Nutritional condition assessment allows evaluating the individual physiological state of larvae, which is an echo of the environmental
