Several investigations have investigated the gut microbiota in shellfish species, but less information is available on the favorable gut bacteria colonizing the GI tract, the lactic acid bacteria (LAB), and these studies have revealed the presence of <i>Carnobacterium, Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, Pediococcus, Streptococcus, Vagococcus</i>, and <i>Weissella</i>. Identification ...

There is increasing pressure to use currently untapped resources in the deep sea, raising questions regarding ecosystem service trade‐offs in these often unknown areas. We assessed the trade‐offs between protection of cold‐water coral reefs and economic activities, such as fisheries and petroleum extraction, through a survey of a representative sample of the populations of Norway and Ireland. ...

There has been a widespread push to incorporate ecosystem services (ES) in research and policy-making, yet ES have remained an expert-driven discourse not well integrated into hands-on planning and management, particularly at the more local levels. We carry out a retrospective investigation of an inter-municipal marine spatial planning (MSP) process in Northern Norway, where the allocation of new ...

This study analyzes fresh and brackish water aquacultures—especially carp, tilapia, and shrimp production—in major Asian aquaculture-producing countries. Different indicators have been used, involving dimensions that may be affected by climate change. High diversity is believed to indicate high adaption capacity, while resilience is estimated by known biological properties of each species. The results ...

Knowledge of the life history of populations at the warm edge of their distributional range can provide a better understanding of how they will adapt to climate warming, including potential poleward redistribution. The range of Gray Snapper Lutjanus griseus has the potential to expand along its northern temperate fringe, but little is known about this species in the warmest portion of its range. ...

Commercial harvesting of snow crab (<i>Chionoecetes opilio</i>) in the Barents Sea started in 2012 by Norwegian fishing vessels. This new fishery has significant bait requirements, representing an emerging conservation challenge. In this study, we evaluate the performance of five alternative (natural) baits manufactured from the waste stream of existing and sustainably managed harp seal (<i>Pagophilus ...

In northern Fennoscandian lakes, monophylogenetic lineages of postglacial fishes are radiating into several adaptive forms, but the speciation process is still at an incipient stage. The speciation process has received increased attention over the years, but the underlying mechanisms and drivers are still debated and poorly understood. European whitefish (<i>Coregonus lavaretus</i> [L.]) is the most ...

Rapporten beskriver hendelsesforløpet og beredskapen i forbindelse med giftalgeangrepet i Astafjorden, Ofotfjorden, Vestfjorden og Tysfjorden våren 2019: hva skjedde, hva ble gjort, hva fungerte og hva fungerte ikke. Rapporten belyser også håndteringen av situasjonen da den oppsto relatert til internkommunikasjon, handlingsrom, disponible ressurser i beredskapen, samt dialog med forvaltning og ...

We focus on a case study along an English canal comparing environmental DNA (eDNA) metabarcoding with two types of electrofishing techniques (wade‐and‐reach and boom‐boat). In addition to corroborating data obtained by electrofishing, eDNA provided a wider snapshot of fish assemblages. Given the semi‐lotic nature of canals, we encourage the use of eDNA as a fast and cost‐effective tool to detect and ...

Microbial community succession is a fundamental process that affects underlying functions of almost all ecosystems; yet the roles and fates of the most abundant colonizers are often poorly understood. Does early abundance spur long term persistence? How do deterministic and stochastic processes influence the ecological contribution of colonizers? We performed a succession experiment within a hypersaline ...
