eDNA Metabarcoding Identifies Fish Conservation Priorities in Deep‐Water Fjords of British Columbia, Canada

Conservation Letters
Fjords are deep‐water estuaries that support a wide range of marine habitats for pelagic fish. Yet, knowledge gaps in fish distribution and habitat use limit the implementation of efficient marine conservation strategies within fjords. Using five British

An Updated Ecology of Atlantic Salmon (Salmo salar) at Sea

Fisheries Oceanography, EarlyView.
ABSTRACT Atlantic salmon have had a key role in European and North American oceans and human societies. Salmon are exploited and observed in rivers and along coasts, but there has always been great interest in knowing where salmon are going when they are at sea.

Glacial Ice‐Front Calving: Internal Wave Generation and Melting

Geophysical Research Letters
Small, frequent calving events dominate the behavior of most Arctic marine‐terminating glaciers, yet their oceanographic impacts remain largely unquantified.

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).

Salmon lice infection on wild salmonids in marine protected areas: an evaluation of the Norwegian ‘National Salmon Fjords’

Aquaculture Environment Interactions, 2014
In Norway, 29 fjords and 52 rivers have been designated for protection in order to prevent the infection of important populations of wild salmonids with salmon lice of farm origin. We evaluated the effect of this protection on the lice infection pressure

Modified fin morphology in mackerel icefish (Champsocephalus gunnari) may indicate nesting behaviour

Journal of Fish Biology, EarlyView.
Abstract Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that the only commercially harvested channichthyid, mackerel icefish (Champsocephalus gunnari), exhibits modifications to their anal ...

Otolith growth of herring (Clupea harengus) and sprat (Sprattus sprattus) in the Norwegian fjords [PDF]

, 2022
Small pelagic fish play an important role in the ecosystem and are an important economical resource. The two most abundant pelagic fish in the Norwegian fjords are herring and sprat.

Underwater light environment in Arctic fjords

<jats:p>Abstract. Most inhabitants of the Arctic live near the coastline, which includes fjord systems where socio-ecological coupling with coastal communities is dominant.
