“…In China, increased number of marine construction where polyps settle and decreased currents (retention) in bays has lead to a higher than usual abundance of moon jellies (Dong et al 2012). Generally speaking, with increasing size of the predatory jellyfish the predation rate increases (Purcell and Arai 2001), so one can imagine that 200-kg jellyfish appearing in millions in a given area can cause severe impacts on the ecosystem and fishing industry.…”

Worldwide increases of jellyfish has occurred during the last several decades. A dense population of a large scyphozoan jellyfish, Periphylla periphylla, has established itself as top predator in the Trondheimsfjord in Norway, impacting traditional fisheries. On this background we discuss the adaptive capacity of artisanal fishers and stakeholder involvement in environmental management. A serendipitous discovery was that fishers report that their capacity to adapt to the presence of jellyfish in fact was sufficient. What they could not adapt to, within the context of jellyfish proliferation, was top–down decisions from the national government allowing purse seiners into the fjord to harvest Sprat Sprattus sprattus and Atlantic Herring Clupea harengus rest quotas and thereby also large bycatches of the local codfishes. This harvest was perceived more detrimental to their fishery than was the jellyfish invasion. Relative to fisheries management's choice of regulatory mechanisms during times of climatic change, we argue that by involving stakeholders intimately, the resulting policy advice will be experienced bottom–up and, thus, more legitimate and serendipitous results of a critical nature are more likely to surface.

“…For example, the medusae may predate on pelagic eggs and larvae of fish, but fish also predate on gelatinous species. Meanwhile, the medusae compete with some small planktivorous fish for the same zooplankton prey (Purcell and Arai, 2001;Richardson et al, 2009). Therefore, some studies suggested that overfishing might help facilitate the jellyfish outbreaks (Purcell et al, 2007;Lynam et al, 2005Lynam et al, , 2006Richardson et al, 2009).…”

“…This perception now appears outdated and international eVorts are underway to redress this long-standing gap in our knowledge (Mills 2001;Purcell and Arai 2001). However, until recently, many questions surrounding the trophodynamics of jellyWsh seemed somewhat intractable given the spatial and temporal variability of aggregations (Doyle et al 2007a;Houghton et al 2007) and the broad scale over which they can occur (Houghton et al 2006;Doyle et al 2008).…”

Preservation methods alter stable isotope values in gelatinous zooplankton: implications for interpreting trophic ecology

et al. 2011

JellyWsh are increasingly topical within studies of marine food webs. Stable isotope analysis represents a valuable technique to unravel the complex trophic role of these long-overlooked species. In other taxa, sample preservation has been shown to alter the isotopic values of species under consideration, potentially leading to misinterpretation of trophic ecology. To identify potential preservation eVects in jellyWsh, we collected Aurelia aurita from Strangford Lough (54 o 22Ј44.73ЉN, 5 o 32Ј53.44ЉW) during May 2009 and processed them using three diVerent methods prior to isotopic analysis (unpreserved, frozen and preserved in ethanol). A distinct preservation eVect was found on 15 N values: furthermore, preservation also inXuenced the positive allometric relationship between individual size and 15 N values. Conversely, 13 C values remained consistent between the three preservation methods, conXicting with previous Wndings for other invertebrate, Wsh and mammalian species. These Wndings have implications for incorporation of jellyWsh into marine food webs and remote sampling regimes where preservation of samples is unavoidable.
