Enhancing fish community monitoring at a cabled observatory by combining environmental DNA and imaging analysis

Journal of Fish Biology, EarlyView.
Abstract Cabled multiparametric observatories are sustaining ecological monitoring by collecting long‐term real‐time biological and environmental data. Here, we investigated fish communities by sampling environmental DNA (eDNA) over 4 days near the multiparametric cabled video‐observatory OBSEA (Northwestern Mediterranean Sea).

Genes, fish and fisheries: translating science into policy

Journal of Fish Biology, EarlyView.
Abstract The 2024 Annual Symposium of the Fisheries Society of the British Isles reviewed the burgeoning impact of ‘omics’ technologies on fish ecology, management and forecasting. As with life sciences more generally, major advances in speed, cost‐effectiveness and breadth of applications in ‘omics’ has had profound societal and environmental impacts.

Comparing environmental metabarcoding and trawling survey of demersal fish communities in the Gulf of St. Lawrence, Canada

Environmental DNA, 2021
Biodiversity assessment is an important part of conservation management that ideally can be accomplished with noninvasive methods without influencing the structure and functioning of ecosystems.

Quantitative insights into the spatio‐temporal variation of Atlantic salmon (Salmo salar) biomass in a river catchment using eDNA metabarcoding

Journal of Fish Biology, EarlyView.
Abstract Effective species conservation and management requires comprehensive biomonitoring, enhanced by combining traditional and newer methodologies, such as environmental DNA (eDNA) analyses. A seasonal pulse of spawning adult Atlantic salmon (Salmo salar) was detected by normalised eDNA 12S reads from metabarcoding, which facilitated estimation of ...

Comparison of Water Sampling between Environmental DNA Metabarcoding and Conventional Microscopic Identification: A Case Study in Gwangyang Bay, South Korea

Applied Sciences, 2019
Our study focuses on methodological comparison of plankton community composition in relation to ecological monitoring and assessment with data sampling. Recently, along with the advancement of monitoring techniques, metabarcoding has been widely used in ...

‘It's not much, but it's honest work’: The status of environmental DNA analyses of fish biodiversity in southern Africa

Journal of Fish Biology, EarlyView.
Abstract Environmental DNA (eDNA) biodiversity surveys have the power to transform the detection of species in natural environments, which is crucial for the conservation and management of freshwater, estuarine and marine environments. Globally, eDNA‐based analyses have increased significantly, with fishes being the most widely studied aquatic ...

Environmental DNA metabarcoding shows potential for monitoring meiofauna and marine nematodes diversity in mangrove ecosystems in China

Ecological Indicators
Mangrove ecosystems, located at the vital interface between land and sea, exhibit exceptionally high biodiversity. Meiofauna are key components in the food webs and nutrient cycles of mangrove ecosystems. However, the diversity of intertidal meiofauna is

Rapid increase in abundance and distribution of invasive pink salmon (Oncorhynchus gorbuscha) within a diverse, large Barents Sea catchment

Journal of Fish Biology, EarlyView.
Abstract Pink salmon originate from the North Pacific area but were introduced into northwest Russia from the late 1950s onwards. Since 2017, the alien species has increased dramatically in abundance and rapidly invaded adjacent areas of the North Atlantic region.

The Tree of Life eDNA metabarcoding reveals a similar taxonomic richness but dissimilar evolutionary lineages between seaports and marine reserves

Molecular Ecology
Coastal areas host a major part of marine biodiversity but are seriously threatened by ever‐increasing human pressures. Transforming natural coastlines into urban seascapes through habitat artificialization may result in loss of biodiversity and key ...

Rapid Clearance of Tetracapsuloides bryosalmonae Spores by Freshwater Sponge Ephydatia muelleri: Potential Implications for Controlling Proliferative Kidney Disease in Salmonids

Journal of Fish Diseases, EarlyView.
ABSTRACT Host–parasite interactions are influenced by both abiotic and biotic factors. While abiotic drivers, particularly temperature, have received considerable attention in recent years due to global climate change, the role of biotic factors remains comparatively underexplored.
