“…Of note, the concentrated aggregation detected in depth around 40m in certain sampling locations was not detected in the surface waters. This is in line with recent studies which showed eDNA dispersal was restricted by halocline [37] and pycnocline [38] using eDNA surveys. The vertical distribution of eDNA depends on the layer where the organism resides and the dispersion and degradation of eDNA [2].…”

Species distribution monitoring and biomass assessment are crucial for fishery management and resource conservation. However, traditional methods such as motor trawling are costly and less effective than the novel environmental DNA (eDNA) approach. This study employs eDNA approach to investigate horizontal and vertical distributions of small yellow croaker (Larimichthys polyactis), an economically important species, in the East China Sea. The analysis of 171 eDNA samples collected from 44 stations using the species-specific primers and Taqman probe suggests a presence of small yellow croaker at 28 sampling layers in 44 stations. Significant differences in croaker eDNA concentrations were revealed among sampling stations and layers, consistent with previous findings through motor-trawl capture offshore and nearshore ichthyoplakton surveys, indicating small yellow croaker exhibits strong regional distribution and layer preference. In addition, we found a high eDNA concentration of small yellow croaker in the surface waters beyond the motor-trawl prohibition line, which confirms spawning grounds have been expanded from nearshore to offshore areas. Such expansion of spawning grounds could be a response by small yellow croaker to stressors such as overfishing, climate change, and nearshore environment contamination. To identify environmental variables potentially associated with small yellow croaker presence and absence, we conducted a correlation analysis between eDNA concentration and environmental variables, and the results provide a guideline for further investigation of fishery resources in the future. In conclusion, this study demonstrates the power of the eDNA approach in monitoring small yellow croaker at extensive geographic scales. The developed protocols and the findings are expected to assist in long-term monitoring and protection programs and benefit sustainable fishery in small yellow croaker.

“…The implementation of eDNA for surveying GZP biodiversity has been integrated within broader assessments of marine biodiversity, including zooplankton in coral reefs in Florida (Djurhuus et al., 2018), as a part of a mesozooplankton survey in the Western Pacific (Feng et al., 2022) and in the mesopelagic zone in the North‐Atlantic (Govindarajan et al., 2021). Studies with a focus on single‐species GZP detection have been increasing in number in temperate and tropical areas including scyphozoan species in the Sea of Japan (Minamoto et al., 2017; Ogata et al., 2021; Takasu et al., 2019), and cubozoans (Bolte et al., 2021; Morrissey et al., 2022). However, the use of eDNA metabarcoding studies truly focused on jellyfish biodiversity and at the community level are limited.…”

Fram Strait, the gateway between the Arctic and Atlantic Oceans, is undergoing major climate change‐induced physical and biological transformations. In particular, rapid warming and ongoing “Atlantification” are driving species range shifts and altering food web structures in the Arctic. Understanding and predicting the consequences of these processes on future ecosystems requires detailed assessments of local and pelagic biodiversity. Gelatinous zooplankton (GZP) is an important component of pelagic communities, and recent evidence indicates that such communities are undergoing major changes in the Fram Strait. However, as sampling GZP is challenging, they are regularly underestimated in biodiversity, distribution, and abundance. To overcome this and address existing ecological knowledge gaps, we investigated patterns of pelagic metazoan diversity in Fram Strait using environmental DNA (eDNA) metabarcoding of the cytochrome c oxidase I (COI) gene. We successfully detected a broad range of taxa from the marine metazoan and GZP communities across sampling locations and ocean depth zones. We demonstrate the vertical structuring of diversity and elucidate relationships between taxa and water mass indicators, such as salinity and temperature. Furthermore, when comparing eDNA data with net and video transect data for GZP at the same period and location, we found that eDNA uncovered a higher number of taxa, including several that were not detected by the other methods. This study is a contribution to the formation of baseline Arctic GZP biodiversity datasets, as well as future research on changing marine metazoan biodiversity and community composition.

“…Recently, a study compared the zooplankton taxa recovered with nets and with eDNA of filtered water samples, and demonstrated eDNA to be particularly suitable for revealing gelatinous diversity (Govindarajan et al, 2021). However, eDNA studies focusing on gelatinous zooplankton still remain relatively scarce (Ames et al, 2021;Gaynor et al, 2017;Minamoto et al, 2017;Takasu et al, 2019).…”

Environmental DNA (eDNA) studies have burgeoned over the last two decades and the application of eDNA has increased exponentially since 2010, albeit at a slower pace in the marine system. We provide a literature overview on marine metazoan eDNA studies and assess recent achievements in answering questions related to species distributions, biodiversity and biomass. We investigate which are the better studied taxonomic groups, geographic regions and the genetic markers used. We evaluate the use of eDNA for addressing ecological and environmental issues through food web, ecotoxicological, surveillance and management studies. Based on this state of the art, we highlight exciting prospects of eDNA for marine time series, population genetic studies, the use of natural sampler DNA, and eDNA data for building trophic networks and ecosystem models. We discuss the current limitations, in terms of marker choice and incompleteness of reference databases. We also present recent advances using experiments and modeling to better understand persistence, decay and dispersal of eDNA in coastal and oceanic systems. Finally, we explore promising avenues for marine eDNA research, including autonomous or passive eDNA sampling, as well as the combined applications of eDNA with different surveillance methods and further molecular advances. Keywords: environmental DNA, DNA metabarcoding, marine metazoa, biodiversity, population genetics, natural sampler DNA, diet analysis.
